PRE-AMBLE
During CMS COP 10 an Action Plan for Migratory Landbirds in the African Landbirds in the African Eurasian
Region (UNEP/CMS) was drafted (Resolution 10.27). This Action Plan was updated by the recently formed
African-Eurasian Migratory Landbirds Working Group under the auspices of the CMS Scientific Council
earlier this year (2014). One of the products of this process was a document entitled “Improving the
Conservation Status of Migratory Landbird Species in the African-Eurasian Region” (UNEP/CMS/ScC18/Doc.
10.7.1.)
Various actions were accordingly requested of the Scientific Council, specifically the council was invited to :
(1) Review and endorse the Action Plan for Migratory Landbirds in the African-Eurasian Region, including
its annexes, and to agree on its submission to COP11 for discussion and adaption,
(2) Provide advice on scientific and technical issues pertaining to the conservation of African Eurasian
Migratory Landbirds and recommed priority researtch to fill existing gaps.
This report is drafted in the above context and aims to contribute to the AEMLAP by focusing on the globally threated and near threatened species (as per Category A of Annex 3). It is also aimed at hopefully complementing this Action Plan by focusing on the research and monitoring guidelines as per Doc. 10.7.1 (pages 18-20). These include and pertain to (1) Understanding migration patterns and connectivity along flyways; (2) Monitoring of population trends; (3) Understanding causes of population change in migratory land bird species; and (4) Building capacity and improve the exchange of information, collaboration and coordination between researchers studying migratory land bird species. This document thus presents a broad summary globally threatened and near threatened bird species. Species are catalogued according to their respective IUCN Red List status (from Critically Endangered to Near Threatened). As a broad overview it is hoped that this approach may complement the work of the CMS Scientific Council and AEMLAP, while recognizing that many issues would need to be explored in greater detail. The focus in the African Eurasian flyway, as defined by the AEMLAP report. However it should be noted that there is a fair amount of overlap with the East Asian-Australasian flyway (for example Pale-backed Pigeon, Bengal and Lesser Florican, Great Bustard, Little Bustard, Marsh Grassbird, Grey-sided Thrush, White-throated Bush Chat, Derbyan Parakeet etc). It is hoped that this framework could complement the objectives of the CMS in general and within the
context of COP11 and the Strategic Plan 2015-2023 in particular. As a follow-up to this report it is
suggested that a similar exercize be conducted with regards to species listed in Category B (according to
UNEP/CMS/ScC18/Doc. 10.7.1.) with decreasing global population trends, and that these reports
complement existing efforts and form the basis of a database on these species going forward. An
appropriate conduit for this would be via BirdLife International’s Migratory Bird Flyways Programme and
it’s associated species information database (see http://www.birdlife.org/datazone/species).

1. Northern Bald Ibis Geronticus eremita (Critically Endangered)
©Marco Valentini
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species only occurs in viable numbers in Morocco, specifically the Souss-Massa National Park & Tamri,
a total range of only some 580 square kilometres. It is thought that birds used to winter in Yemen, Saudia
Arabia, Eritrea and Sudan. It also used to occur in Turkey, but is critically endangered and possibly even
extinct there.
MONITORING POPULATION TRENDS
In Souss-Massa National Park and Tamri, Morocco, 113 pairs (i.e. 226 mature individuals) nested, out of
319 adults in 2013, and produced 148 fledged young. In 2011, at least 100 pairs produced at least 130
fledged young, matching the breeding success of 2010, when 105 pairs fledged 138 young. After the
breeding season the total number of birds in the western population may have exceeded 500 in 2011-
2012, but most recently has been evaluated as 443 individuals. Only a single mature female returned to
Syria in 2013, and 2011 was the last successful breeding when a single breeding pair fledged two young.
The Turkish population now numbers around 100 individuals, but these managed birds are excluded from
the total estimate (BirdLife International 2014; Smith et al 2000).
CAUSES OF POPULATION CHANGE
Combination of factors, especially disturbance and persecution by man from hunting and also the loss of
habitat, poisoning from pesticides and the construction of dams.
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Conduct research into their habitat requirements and feeding and breeding biology (Bowden et al
2003); (2) monitor numbers and breeding success; (3) try to prevent disturbance and development near
their key breeding and roosting sites; (4) establish their ecological requirements and use this information
to try to reintroduce captive-bred birds into previously occupied sites (Brindley et al 1995).

2. Bengal Florican Houbaropsis bengalensis (Endangered)
©Ramki Streenivasan
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
There are two disjointed populations. The first is in Indian subcontinent, where it occurs in fragmented
subpopulations in the region of Uttar Pradesh, Assam and Arrunachal in India as well as an isolated
subpopulation in the terai of Nepal. It formally occurred in Bangladesh but is thought extinct there. The
other population is in South-East Asia where it occurs in Cambodia and adjacent southern Vietnam
(BirdLife International 2000).
MONITORING POPULATION TRENDS
The population of this species is decreasing and it is classified as endangered. The population in Cambodia
was estimated at 294 displaying males or c.600 individuals in 2009, but recently an extensive survey has
reported a total of only 432 individuals (95% CI 312-550). 75-96 individuals remain in Nepal. No recent
estimates are known from India but the total global population for this species is likely to fall in the range
250-999 mature individuals. This equates to 375-1,499 individuals in total, rounded here to 350-1,500
individuals (BirdLife International 2014).
CAUSES OF POPULATION CHANGE
The primary cause of the decrease in numbers is the significant loss and modification of its grassland
habitat through the conversion to agriculture, drainage, overgrazing, over cutting, inappropriate burning
regimes, flooding, hunting, human disturbance and the trampling of nests by livestock (BirdLife
International 2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Conduct surveys for populations, especially in Cambodia; (2) monitor current populations; (3) expand
and connect existing protected areas and establish new ones; (3) promote and implement rotational
burning, grazing and cutting regimes in protected areas; (4) control human disturbance and hunting; (5)
facilitate the regeneration of grassland habitats; (5) promote awareness campaigns about grassland
conservation; (6) integrate these efforts with existing strategies to conserve bustards in India.

3. Lesser Florican Sypheotides indica (Endangered)
© Rakesh Ranjan
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species breeds in several isolated sub-populations in India and disperses within India in the non-
breeding season. It has also been recorded in Pakistan and is a summer migrant to Nepal.
MONITORING POPULATION TRENDS
Formally far more common, the Lesser Florican has declined in numbers throughout its range. By 1994 its
numbers were estimated at around 2200 birds. It is now classified by the IUCN Red List as Endangered
(BirdLife International 2000).
CAUSES OF POPULATION CHANGE
Pressure from hunting for sport and food, loss and degradation of its grassland habitat from overgrazing
and conversion for agriculture. It is also particularly susceptible to climate change
(BirdLife International 2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Monitor and update population size and status; (2) Try to establish a network of grassland habitats and
demarcate protected areas; (3) Improve the management of grasslands through sustainable use; (4)
Involve local people to act as guardians in protecting floricans and their habitat; (5) Integrate these efforts
with existing strategies to conserve bustards in India.

4. Spotted Ground Thrush Zoothera guttata (Endangered)
©Sion Stanton
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species occurs in a number of widespread but localized areas with limited connectivity between them.
These include Kwazulu-Natal in South Africa, possibly in Mozambique with isolated populations in Kenya
(Arabuko-Sokoke Forest) and Tanzania (Litipo and Rondo Plateau Forest Reserve) and Malawi (Bennun and
Njoroge 1999). The coastal forest patches in Tanzania are under pressure and becoming increasingly
fragmented. Wintering habitat in Kenya is also under pressure (Waiyaki & Bennun 1999). Single specimens
have been collected in the DRC and Sudan.
MONITORING POPULATION TRENDS
This fragmented range with increasing threats to its habitat suggests it should be classified as Endangered.
Its population in the year 2000 was thought to be between 1000 and 2500 birds but decreasing (BirdLife
International 2000).
CAUSES OF POPULATION CHANGE
Increasing habitat destruction and associated disturbance is the primary threat to this species. In South
Africa mining has destroyed much of its wintering habitat (Barnes 2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Identify habitats and breeding sites for this species and areas that could connect their migratory
patterns, particularly in Tanzania and Mozambique; (2) Clarify the status of its forest habitat in South Africa
and improve protection at these sites; (3) Promote the conservation of water resources within the
remaining forest reserves in Malawi; (4) Investigate its status in Sudan and DRC (BirdLife International
2000).

5. Yellow-breasted Bunting Emberiza aureola (Endangered)
©Johan Stenlund
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
Emberiza aureola breeds across the northern Palaearctic from Finland, Belarus and Ukraine in the west,
through Kazakhstan, China and Mongolia, to far eastern Russia, Korea and northern Japan. In the autumn,
birds stop-over in large numbers to moult in the Yangtze Valley, China, before continuing on to their winter
quarters. It winters in a relatively small region in South and South-East Asia, which includes eastern Nepal,
north-eastern India, Bangladesh, Myanmar, southern China, Cambodia, Laos, Vietnam and Thailand.
MONITORING POPULATION TRENDS
It was formerly classified as a near threatened species by the IUCN .However it has declined severely in
most breeding areas and it has completely disappeared from parts of its former breeding range since the
early 1990s. Severe declines have been noted in Finland, Kazakhstan, Hokkaido, Japan and Mongolia
(BirdLife International 2014b). It is estimated to have declined by at least 70% in European Russia between
2000 and 2010 suggesting a massive decline in the core range (BirdLife International
2014b). Consequently, it was uplisted to vulnerable status in 2008 and then to endangered in 2013.
CAUSES OF POPULATION CHANGE
Since many populations on pristine breeding grounds have dropped rapidly, the decline is likely to be
driven by excessive trapping at migration and, in particular, wintering sites (Chan 2004) Roosting flocks in
reedbeds are disturbed and then caught in mist-nets, they are cooked and sold as "rice-birds"; this practice
was formerly restricted to a small area of southern China, but has now become more widespread and
popular owing to increasing affluence, and hunters now have to travel widely to find sufficient birds.
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1): A programme of co-ordinated range-wide monitoring and action is badly needed to quantify the
magnitude of the decline and reduce the impact of threats; (2) Implement a programme of co-ordinated
range-wide monitoring at breeding, passage and non-breeding sites, in order to quantify the rate of
decline. Through awareness campaigns, reduce the demand for the species as a food item, mascot and
merit-bird; (3) Research its precise habitat requirements on the wintering grounds; (4) Protect sites which
still hold large numbers on the wintering grounds.

6. Basara Reed Warbler Acrocephalus griseldis (Endangered)
©Mike Pope
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
Acrocephalus griseldis breeds in the Mesopotamian marshes of south-east Iraq (between Baghdad and
Basra) (Maltby 1994) and probably in south-west Iran in the Hawr Al Hawizeh marsh complex of Khuzestan
two pairs have been recorded breeding in Israel. It winters in Sudan, South Sudan, Ethiopia, south
Somalia, south-east Kenya (Urban et al. 1997), east Tanzania, south Malawi (few records) and
Mozambique. It is regular on passage in Saudi Arabia and Kuwait (where it may breed).
MONITORING POPULATION TRENDS
The population is estimated to number 2,500-9,999 individuals based on an assessment of known records,
descriptions of abundance and range size. This is consistent with recorded population density estimates for
congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated
Extent of Occurrence is likely to be occupied. This estimate is equivalent to 1,667-6,666 mature individuals,
rounded here to 1,500-7,000 mature individuals.
CAUSES OF POPULATION CHANGE
Since the 1950s there has been considerable loss of its shallow, marshy wetland habitat due to large-scale
hydrological projects throughout the Euphrates and Tigris river-basins (Maltby 1994). Improvement in
access to the region, with consequent increases in settlement, has resulted in increased disturbance and
water pollution (Maltby 1994). The 130,000 ha Tana River Delta in Kenya, a key wintering site, is
threatened by large-scale conversion for agriculture (food and biofuels), including Kenyan based
organisations wanting to establish huge sugar cane plantations on over 70,000 ha of land, companies from
Canada and the UK wanting to grow oil seed crops on over 60,000 ha, possible mining in the sand dunes
and prospecting for oil and gas (RSPB 2012).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Confirm whether Acrocephalus griseldis breeds in the marshes of Khuzestan, Iran; (2) Continue to
monitor migrating birds at Ngulia (Kenya) to assess population trends; (3) Conduct surveys to assess
whether the species now breeds in sub-optimal habitats, e.g. further up the Euphrates/Tigris north of
Baghdad; (4) Investigate possibilities for habitat restoration (BirdLife International 2014).

7. Southern Bald Ibis Gerontics calvus (Vulnerable)
©Althepal, en.Wikipedia
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
Occur in north-east South Africa, Lesotho and west Swaziland, with a range of some 200 000 square
kilometres.
MONITORING POPULATION TRENDS
Classified as Vulnerable. Estimated total population size: approximately 8000, comprising of 2000 breeding
pairs (Henderson et al 2012). In South Africa there are over 1500 breeding pairs at just over 100 colonies
(although about 25% occurs at 5 sites). In Swaziland there are three main breeding colonies supporting 10
pairs each and a total population of about 110 birds. In Lesotho the bird still occurs in fairly high numbers,
CAUSES OF POPULATION CHANGE
Habitat loss through intensive crop farming, poisoning from pesticides, commercial afforestation, opencast
mining, acid rain and human settlement. In Lesotho birds are killed for ceremonial purposes. Also natural
predation from raptors.
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1) Assess its status in Lesotho from surveys; (2) Start range-wide monitoring to help clarify population
trends. (3) Protect as many as the larger breeding colonies and feeding areas as possible. (4) Identify uses
of grassland with fewer negative impacts than forestry and provide incentives for their rapid adoption.

8. Great Bustard Otis tarda (Vulnerable)
© Ignacio Yufera
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species breeds in Morocco, Portugal, Spain, Austria, Germany, Slovakia, Hungary, Bulgaria,
Yugoslavia, Romania, Moldova, Turkey, Iran, Russia, Ukraine, Kazakhstan, Kyrgystan, Tajikistan,
Uzbekistan, Mongolia and China (BirdLife International 2000). Its Palearctic range is becoming increasingly
disjunct with rapid declines throughout eastern Europe and Asia. The population in north-eastern China
and Mongolia is now separated from those in Kazakhstan, similarly from those in Ukraine and Russia. The
populations in Portugal and Spain, the latter of which supports the highest numbers, are also becoming
increasingly isolated.
MONITORING POPULATION TRENDS
The total population is estimated to number 44,054-57,005 individuals, rounded here to 44,000-57,000
individuals (BirdLife International 2014). Highest sub-populations occur in Spain, Russia and China.
CAUSES OF POPULATION CHANGE
Main threats are increased human disturbance, mainly due to the expanding agriculture practices industry
throughout its range. Ploughing of grasslands, over-grazing by livestock, chemical fertilizers and pesticides
as well as irrigation schemes have led to habitat loss and declines in their population. Afforestation and the
construction of roads, powerlines, fences as well as hunting in Ukraine and China are also major threats
(Chan and Goroshko 1998).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Identify the limiting factors; (2) Identify protect and manage their breeding areas; (3) Try to ensure the
availability of habitat in their wintering range; (4) Establish new protected areas in east Asia and maintain
existing ones; (5) Try to mitigate the impacts of agriculture by promoting low-intensive farming in their
range; (6) Mitigate the effects of fire, illegal hunting and collision with power lines; (7) Raise public
awareness (BirdLife International 2000).

9. Blue Swallow Hirundo atrocaerulea (Vulnerable)
©Warwick Tarboton
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
The Blue Swallow is an intra-African migrant that breeds in South Africa, west Swaziland, Zimbabwe,
Malawi, north-east Zambia, south-western Tanzania, west Mozambique and southeast DRC (BirdLife
International 2000). It is a non-breeding visitor to north-east DRC, south Uganda and west Kenya.
MONITORING POPULATION TRENDS
The total population has declined by an estimated 36-56% since the 1850s, and is now estimated at
approximately 1500 to 3800 individuals. Estimated numbers of breeding pairs may be less than one
expects, as when nests are surveyed they are assumed to indicate one breeding pair each, which may not
be the case in this facultative cooperative breeder, and it has been observed that some nests are not used
after construction (Wakelin 2007). The largest population is in Tanzania and Malawi, it is uncommon in
Uganda and Kenya, rare in Zambia and Zimbabwe and critically endangered in Swaziland and South Africa
(BirdLife International 2000).
CAUSES OF POPULATION CHANGE
The Blue Swallow is threatened by destruction and degradation of its grassland habitat on both its
breeding grounds and wintering sites. This included human settlement, cultivation, intensive livestock
farming, intense grazing, burning, and invasion of exotic trees
(Keith et al 1992; Nasirwa and Njoroge 1997).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Identify key wintering sites and conserve them; (2) Survey and monitor breeding populations and
trends at less well-studied sites; (3) Control and remove non-native plants at breeding sites; (4) Assess
effects of grassland fires on spread of non-native plants.

10. Pale-backed Pigeon Columba eversmanni (Vulnerable)
© Kumpulan Kliping Hare
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species is known to breed in Kazakhstan, Uzbekistan, Turkmensitan, Tajikistan, Kyrgystan,
Afghanistan, northeast Iran and north-west China. Pale-backed Pigeons move south towards the Arabian
Seas during the winter where they frequent Pakistan and north-west India during this season.
MONITORING POPULATION TRENDS
During the 19th and 20th centuries huge flocks occurred in their wintering grounds, particularly in the
Punjab, India. However their population has declined rapidly. The current population size is thought to
number 15,000-30,000 individuals (BirdLife International 2014)
CAUSES OF POPULATION CHANGE
Habitat loss and degradation, exploitation from hunting (especially China). In India, cultivation and
conversion of habitat to wheat and rice has reduced habitat in wintering areas. In east Kazkhstan
destruction of polar woodland is believed to have had a major negative impact on the breeding population.
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1): Clarify the size and distribution, key threats and habitat requirements within its breeding range; (2)
Similarly survey habitat requirement on their wintering range; (3) Improve the management of protected
areas where this species occurs and protect important breeding habitat from further degradation; (4)
Protect it from hunting pressures especially in China and India (BirdLife International 2000).

11. Marsh grassbird Megalurus pryeri (Vulnerable)
© Japanese Class.jp
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species is known to breed at only six localities in Japan and one site in China and Russia respectively. It
winters in Honshu and Shikoku Islands, Japan and the Yangtze basin in China. This species has also been
recorded in eastern Mongolia and South Korea, and is thought to also occur in North Korea (BirdLife
International 2000).
MONITORING POPULATION TRENDS
The population is thought to be in the range of 2500 to 10 000 individuals but is thought to be decreasing.
The population in Japan was estimated to be approximately 1000 birds in the year 2000 (BirdLife
International 2000).
CAUSES OF POPULATION CHANGE
The main threat to this species is the loss and degradation of marshes in its breeding and wintering
grounds. Some of its breeding sites are also being converted to agriculture. Wetlands along the Nen Jiang
river in China are threatened by oilfield development, reed harvesting and the alteration of water-levels
sue to irrigation. Pollution and hunting are also threats in China. In Japan, many breeding areas are in
abandoned rice-fields which would be lost if agriculture production renews there (BirdLife International
2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Survey potential breeding grounds in Russia, China and North Korea; (2) Develop habitat management
plans at key breeding sites; (3) Ensure legal protection in all range countries and within all important sites
(BirdLife International 2000).

12. Bristled Grasssbird Chaetornis striatus (Vulnerable)
© PM Laad
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species occurs primarily in northern India and the terai of southern Nepal, with isolated sub-
populations in Pakistan.
MONITORING POPULATION TRENDS
The population was estimated at between 2500 and 10 000 in the year 2000, but thought to be decreasing
in numbers (BirdLife International 2000). It has declined in many parts of India and Bangladesh, where it
was formally common.
CAUSES OF POPULATION CHANGE
Degradation of its grassland habitat, primarily through drainage and conversion to agriculture. The
remaining habitat is vulnerable to intense pressure from human encroachment, fire, grass harvesting,
grazing by livestock, commercial frosty plantations, dam construction and irrigation schemes (Birdlife
International 2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1): Conduct surveys to establish its current distribution and population status; (2) Investigate its
behavioural ecology and seasonal movements, both inside and outside protected areas to identify the
effects of differing land-use; (3) Identify the most important sites for this species, try to prioritize such sites
for formal protection; (4) Try to regulate and mitigate the harvesting of grass and encroachment at its key
sites (BirdLife International 2000).

Grey Sided Thrush Turdus feae (Vulnerable)
© Ayuwat J (from Bird Forum.net)
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species breeds in the mountains of north-east China and appears to over-winter in north-east India,
Myanmar, north-west Thailand and Laos. It breeds in temperate deciduous oak forest and pine forest at
an altitude of between 1000 and 1900 metres and winters in evergreen forest generally at higher altitudes
(BirdLife International 2000).
MONITORING POPULATION TRENDS
Given the relatively small number of recent records and its apparent low population density, this species
could have a small total population, i.e. fewer than 10,000 individuals. The global population is estimated
to number 2,500-9,999 mature individuals. The population in China at 100-10,000 breeding pairs and 50-
1,000 individuals on migration (BirdLife International 2014). The population of this species is thought to be
decreasing and it is classified as Vulnerable.
CAUSES OF POPULATION CHANGE
Deforestation is thought to be the main cause of population decline, especially in China. In Thailand and
Myanmar, forests are being affected by agriculture, wood collection and fire (BirdLife International 2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1): Study the ecology and breeding habitat requirements in order to develop optimal forest management
practices in the protected areas in which it occurs; (2) Investigate the overlap between protected areas
demarcated for the Brown-eared Pheasant Crossoptilon mantchuricum and the conservation of the Grey-
sided Thrush. (3) List as a protected species in China; (4) Promote the extension of Pangquangou National
Nature Reserve and strengthen the protection at Lao Ling and Baihuashan Nature Reserve in China
(BirdLife International 2000).

14. Machurian Reed-warbler Acrocephalus tangorum (Vulnerable)
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species breeds in south-east Russia and north-east China, and is known to winter in Thailand. It also
occurs as a passage migrant in Vietnam, although rare. It is thought to also possibility over-winter at Laos
and Cambodia.
MONITORING POPULATION TRENDS
The overall population is small (fewer than 10 000) and decreasing and thus species is classified as
Vulnerable (BirdLife International 2014).
CAUSES OF POPULATION CHANGE
The main threat is the loss of suitable marshland habitat especially in its wintering grounds, due to
urbanization, reclamation, encroachment from plantations of eucalyptus and coconut palms, and
contamination of the water from farming practices.
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1) Rehabilitate reed swamps where possible; (2) Survey suitable habitat in its breeding and wintering
ranges to clarify population size and distribution; (3) Protect Khao Sam Roi Yot National Park in Thailand
and propose ways whereby ecological objectives which help protect this species are compatible with the
aspirations of the local people; (4) Encourage Thailand to ratify the Ramsar Convention in general (BirdLife
International 2000).

15. Aquatic Warbler Acrocephalus paludicola (Vulnerable)
©Vytautas JUSYS
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species breeds across a fragmented range in Hungary, Poland, Belarus, Ukraine, Russia, Germany and
Lithuania. It is thought to winter in West Africa.
MONITORING POPULATION TRENDS
Estimated numbers and population size per country (based on records of singing males as per Aquatic
Warbler Conservation Team 1999; Kozulin and Flade 1999) are Hungary: 600; Poland: 2900-3000; Belarus:
7300 – 13000; Ukraine: 2400-3400; European Russia: 10-500; Germany: 40-50 and Lithuania: 250-400.
Two-thirds of the known population has been discovered since 1995. Total population is estimated at
between 13 500 and 21 000 singing males. Overall the species is classified as vulnerable due to declines in
the extent of occurrence and area of occupancy (BirdLife International 2000).
CAUSES OF POPULATION CHANGE
The major threats are loss of breeding habitat due to drainage for agriculture, damning of floodplains and
canalizations of rivers. Uncontrolled fires are also a threat. In the wintering grounds drought, wetland
drainage, intensive grazing, desertification and salinization of irrigated soils are all potential threats
(BirdLife International 2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Conduct surveys in Siberia to assess its status there; (2) Implement a monitoring programme; (3)
Protect key breeding sites; (4) Promote protection of the species and its habitat in wintering areas and
along the migration route; (5) Ensure legal protection (BirdLife International 2000).

16.Kashmir Flycatcher Ficedula subrubra (Vulnerable)
© Varun HB
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
The Kashmir Flycatcher breeds in Pakistan (Neelum Valley and Kaz-i-nag Range), and the extreme
northwest of India (in Kashmir and the Pir Panjal range). It is thought to migrate south from here during
the winter months where it occurs in the hills of central-southern Sri Lanka, and also the southern Western
Ghats in India. It occurs as a passage migrant in Nepal and as a vagrant to Bhutan
(BirdLife International 2000).
MONITORING POPULATION TRENDS
Formally much more common, it is now classified as Vulnerable, with an estimated (declining) population.
It is unlikely that it currently numbers more than a few thousand (perhaps 1500 – 7000) individuals
(BirdLife International 2014).
CAUSES OF POPULATION CHANGE
The species is declining due to habitat loss and degradation due to commercial timber extraction,
conversion of its habitat for agriculture, grazing by livestock (BirdLife International 2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1) Conduct surveys across its breeding range to establish its current population status; (2) Conduct
detailed research into its breeding habitat requirements; (3) Identify key breeding and wintering sites and
campaign for protection of these sites; (4) Provide support for more effective management of protected
areas within its range (BirdLife International 2000).

© James Eaton
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
The Dark-rumped Swift is known from only a few breeding colonies in the hills of Meghalaya and Mizoram
in north-east India and the adjacent Himalayan foothills of Bhutan. It is thought to possibly overwinter in
Thailand and Myanmar.
MONITORING POPULATION TRENDS
This species is very scarce. The population is thought to number 250-999 individuals, based on estimates of
breeding colony sizes ranging from a few to 200 individuals. This estimate equates to 167-666 mature
individuals, rounded here to 150-700 mature individuals (BirdLife International 2014). However it is
possible that other breeding sites occur but have not been recorded as yet.
CAUSES OF POPULATION CHANGE
There are no significant known threats to this species.
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1): Protect existing colonies; (2) Conduct surveys across its known breeding range to assess its population
status, seasonal movements and possible threats (BirdLife International 2000).

MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species breeds in the extreme southeast regions of Russia, as well as various islands in Japan and off
South Korea. It also occurs in Taiwan and as a passage migrant along the eastern coast of China, and is
presumed to overwinter in the coastal wetlands of south China.
MONITORING POPULATION TRENDS
The population is thought to be a few thousand individuals. However the species is poorly known and
difficult to detect. It is classified as Vulnerable (BirdLife International 2000). National population estimates
include: < c.100 breeding pairs and < c.1,000 individuals on migration in China; < c.50 individuals on
migration and < c.50 wintering individuals in Taiwan; c.100-10,000 breeding pairs and c.50-1,000
individuals on migration in Korea; c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in
Japan and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia. The total
population is placed in the range of 2,500-9,999 mature individuals, equating to 3,750-14,999 individuals,
rounded here to 3,500-15,000 individuals (BirdLife International 2014).
CAUSES OF POPULATION CHANGE
The primary threat to this species is habitat loss and degradation.
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1): Survey small islands within its potential breeding range and suitable habitat within its wintering range
in order to clarify its population, habitat requirements and threats; (2) Extend the boundaries of the Far
Eastern Marine Reserve in Peter the Great Bay, to include islands where it breeds; (3) Strengthen
protection of the buffer zones around Mai Po Marshes Nature Reserve and control development where
possible (BirdLife International 2000).

19. White-throated Bush Chat Saxicola insignis (Vulnerable)
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species breeds primarily in the mountains of Mongolia. It appears that it migrates through northern
and western China and overwinters in northern India and Nepal.
MONITORING POPULATION TRENDS
The population size is estimated at between 2500 and 10 000 mature individuals (BirdLife International 2000). This is
equivalent to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals (BirdLife International
2014). Formally a lot more common the population is decreasing and this species is now rare and local in its
wintering range.
CAUSES OF POPULATION CHANGE
The major threat appears to be the rapid and extensive loss and modification of grasslands in its wintering
grounds, as a result of drainage, conversion to agriculture, overgrazing, grass harvesting for thatch
production and inappropriate grassland management within protected areas. (BirdLife International 2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1): In order to identify important sites for this species and associated threats, it has been recommended
that further surveys for the species across its breeding and wintering range should be conducted. (2) In
order to adequately conserve remaining tracts of natural grassland, it has been recommended that
protected areas where this species occurs should be extended, upgraded and linked to existing protected
areas and new protected areas should be established. (3) Widespread conservation awareness initiatives
focusing on sustainable management of grassland should be promoted in order to maximize both available
habitat for threatened grassland birds without compromising the productive harvesting of thatching grass
for local people.

Ethiopia, Kenya, Uganda, Tanzania, Rwanda, Burundi, DRC, Congo, Gabon, Angola, Malawi, Zambia,
Namibia, Zimbabwe, Botswana, southern Mozambique, South Africa, Lesotho and Swaziland.
MONITORING POPULATION TRENDS
Although very widely distributed, it has suffered population declines through much, if not all of its range
(Urban et al 1986).
CAUSES OF POPULATION CHANGE
Hunting is the primary cause of declines across the Sahel (Newby 1990) and throughout West Africa. In
southern Africa the main threat appears to be conversion of grassland habitats to agriculture (Collar 1996).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1) Promote stewardship arrangements which may benefit Stanley’s bustard (for example in the
Overberg, South Africa); (2) Maintain suitable habitats; (3) regulate indiscriminate hunting;

21. Houbara Bustard Chamydotis undulata (Near threatened)
©Stephen Burch
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species occurs over a wide range, from northern Africa to China. There are three subspecies: -
C.u.undulata occurs in Libya, Egypt and Tunisia. C.u.fuertaventurae occurs on the Canary Islands, Spain.
C.u.macqueenii breeds in the Middle East, and from eastern Iran to Kazakhstan and Turkmenistan and
China. Populations from some subregions are thought to mix on the wintering grounds (Goriup 1997).
MONITORING POPULATION TRENDS
The overall population may is estimated at 60 000 birds but may be as high as 100 000 birds. This includes
the various subspecies – C.u.undulata approximately 10 000 birds; C.u.macquuenii, 39 000 – 52 000 birds;
C.u.fuertaventurae is the least common with only 700 individuals. Overall declines have been reported
from Bahrain, Jordan, Iran, Iraq and India (BirdLife International 2000).
CAUSES OF POPULATION CHANGE
The main threats are habitat loss and degradation as desert areas are developed for agriculture and
infrastructure projects. These are compounded by high hunting pressure from falconers
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Mitigate the impacts from agriculture; (2) Regulate falconry practices.

22. Little Bustard Tetrax tetrax (Near Threatened)
© Mike Watson
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species has two widely separated breeding populations. In its eastern range it is most common in
Kazakhstan and Russia and also occurs in Ukraine, northwest China, northern Italy and Turkey. In its
western range it is most common in Spain and Portugal and also occurs in smaller numbers in Italy, France
and possibly Morocco (BirdLife International 2000).
MONITORING POPULATION TRENDS
This species in classified as Near-threated as the global population is still over 200 000 individuals (BirdLife
International 2000). However it has declined rapidly since the 19th century, and it is extinct in a number of
countries where it formally occurred.
CAUSES OF POPULATION CHANGE
The main cause of its decline has been the conversion of dry grassland and low intensity cultivation to
intensive farming such as monocultures. It is also threatened by irrigation and afforestation. Specifically
the main threats to the little bustard are related to farming and land use changes, include killing of females
and juveniles by farm machinery during harvesting; insufficient insect food leading to starvation and low
breeding success and habitat loss and fragmentation (edge effects) causing local extinctions (Inigo & Barov
2010). It is also threatened by illegal hunting.
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1) Maintain the current distribution of the little bustard and prevent local extinctions; (2) Increase the productivity of the breeding populations to more than 1 chick per female; (3) Apply suitable mitigation
measures (to reduce mortality) and agri-environmental schemes (to ensure suitable habitats for nesting and abundant insect food for chick rearing); (4) Maintain Steppe and steppe-like habitats with diverse
structure throughout the range; (5) Protect steppes as a priority habitat and their conversion to other land-uses (arable farming, infrastructure development, afforestation) has to be prevented (Inigo & Barov 2010).

23. Syrian Serin Serinus syriacus (Near Threatened)
© www.hulabirdfestival.org
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species only breeds in mountainous regions in the middle-east (Syria, Lebanon, Mount Hermon in
Israel and Jordon). In winter, birds in Jordon disperse locally (Khoury 1999), and the breeding grounds in
Lebanon, Syria and Israel are completely vacated for wintering grounds that probably comprise desert and
semi-arid country at lower altitudes as far afield as Egypt and Iraq (Evans 1994).
MONITORING POPULATION TRENDS
The total population is estimated at not more than 4000 individuals (Khoury 1999) which includes 1000-
1250 individuals in Jordon, and 100-360 individuals in Israel (Evans 1994).
CAUSES OF POPULATION CHANGE
This species may be negatively affected by excessive tree cutting, grazing and water abstraction as it feeds
on the seeds of annual grasses and herbs and requires daily access to water (Khoury 1999).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Update and verify population sizes throughout its range; (2) Continue monitoring efforts in Jordon; (3)
Reassess its conservation status with consideration for up-listing to CMS Appendix I.

© Polina Clarke
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species breeds along arctic coasts from central Alaska, USA to Devon Island, Canada, with a disjunct
sub-population on Wrangle Island and west Chukotka in Russia. Birds winter in South America, including
Argentina, Uruguay, Paraguay and Bolivia.
MONITORING POPULATION TRENDS
This species used to be abundant at the beginning of the twentieth century, but was brought to the brink
of extinction due to hunting by the 1920s. The global population is estimated to number c.16,000-84,000
individuals (Morrison et al. 2006)
CAUSES OF POPULATION CHANGE
The breeding grounds may be affected by habitat loss and degradation, and environmental contaminants.
Exposure on migration to toxic chemicals and pollutants in its agricultural feeding grounds may pose a
threat, and is being investigated further (Lanctot 2006, McCarty et al. 2009)
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1): Implement priority actions identified at the Buff-breasted Sandpiper symposium; (2) Ascertain the
population size and trend for the species; (3) Complete a species action plan; (4) Conserve key staging and
wintering grasslands; (5) Investigate the quality of foraging habitat and the influence of contaminants at
the agricultural feeding grounds used on migration (McCarty et al. 2009).

25. Tytler’s Leaf Warbler Phylloscopus tytleri (Near threatened)
© Jayaram Jahgirdar
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
Phylloscopus tytleri breeds in the western Himalayas in Pakistan and Kashmir, India (generally from 2,000-
3,600 m), passes through Nepal in small numbers during migration and winters mainly in the Western
Ghats and Deccan hillocks of peninsular India (Praveen 2007).
MONITORING POPULATION TRENDS
It is scarce to locally common in Pakistan and Kashmir, rare in Nepal, and infrequently recorded in its
wintering range, partly due to identification difficulties.
CAUSES OF POPULATION CHANGE
Declines are likely to be occurring as a result of habitat loss and degradation in both breeding and
wintering grounds.In its breeding range, forests are under constant threat from timber extraction,
excessive cutting for fuelwood and animal fodder, livestock grazing and burning. In its wintering range,
increasing encroachment into forests, livestock grazing, hydroelectric power development, road-building
and the harvesting of fuelwood and huge quantities of forest products such as bamboo and canes are
causing reductions in forest cover in the Western Ghats.
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1) Conduct repeated surveys within the breeding range to assess its current distribution and
abundance, as well as identify population trends and rates of habitat loss; (2) Conduct wider
surveys in areas surrounding known winter sites to determine the full extent of the winter range;
(3) Conduct ecological studies to improve understanding of its precise habitat requirements,
tolerance of secondary habitats and response to fragmentation in both winter and summer ranges;
(4) Effectively protect significant areas of suitable forest at key sites on both breeding and wintering
grounds, in both strictly protected areas and community-led multiple use areas (BirdLife
International 2014).

MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
The Japanese Waxwing breeds only in the far east of Russia where it occurs in coniferous forests. It is a
non-breeding visitor to Japan, South Korea, China and Taiwan (BirdLife International 2000).
MONITORING POPULATION TRENDS
It is locally common on the breeding grounds, but given its limited range, the total population is expected
to be small. It is uncommon and sporadic in Japan, South Korea, China and Taiwan (BirdLife International
2000).
CAUSES OF POPULATION CHANGE
The Japanese Waxwing is thought to be negatively affected by the logging and development of its natural
forest habitat (BirdLife International 2000).
CONSERVATION TARGETS/ RESEARCH PRIORITIES
(1) Closely monitor this species in its breeding grounds and non-breeding grounds; (2) mitigate the
effects of logging and development and protect the habitats where it occurs.

27. Japanese Quail Coturnix japonica (Near threatened)
©Nobuo Matsumura
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
Coturnix japonica breeds in eastern Asia, including northern Mongolia, Sakhalin Island and the Baikal and
Vitim regions of Russia, north-eastern China, Japan, North Korea and South Korea. Some populations in
Japan are resident, but most birds migrate south, wintering in southern China, Laos, Vietnam, Cambodia,
Myanmar, Bhutan and north-eastern India (del Hoyo et al. 1994). There are also introduced populations in
Italy and Hawaii (USA).
MONITORING POPULATION TRENDS
No reliable population estimate exists, and although the species was previously considered to be fairly
common in China (del Hoyo et al. 1994), declines appear to have occurred in Laos (Duckworth 2009) and
Japan (Okuyama 2004), and there are fears that the species has undergone a significant decline overall (del
Hoyo et al. 1994, Duckworth 2009).
CAUSES OF POPULATION CHANGE
Specific threats to the species are unknown, although it may be threatened by agricultural change in Asia
(Duckworth 2009). Hunting is a threat in Japan (Okuyama 2004), and is likely to be a threat elsewhere in its
range.
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1) Obtain an up-to-date population estimate; (2) Develop a monitoring scheme to establish population
trends; (3) Identify and assess the impacts of known and potential threats throughout its range
(BirdLife International 2014).

MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species breeds in wetlands with tall grass and scrub in Primorye in extreme south-east Russia, Japan,
north-east China and is a passage migrant and visitor to North Korea, where it is thought to breed (BirdLife
International 2000).
MONITORING POPULATION TRENDS
The Ochre-rumped Bunting is uncommon or rare throughout its range. National population estimates
include: c.100-10,000 breeding pairs, c.50-1,000 individuals on migration and < 50 wintering individuals in
China; < 1,000 wintering individuals in Korea; c.100-10,000 breeding pairs, c.50-1,000 individuals on
migration and < 50 wintering individuals in Japan and c.100-10,000 breeding pairs and c.50-1,000
individuals on migration in Russia (Brazil 2009). Overall, the global population may number c.10,000-19,999
individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature
individuals (BirdLife International 2014).
CAUSES OF POPULATION CHANGE
While the reason for its apparent decline is not known it is presumably declining still because of the loss
and degradation of wetland habitat within its breeding range, and the destruction of coastal marshes in its
Asian wintering grounds (BirdLife International 2014d).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Monitor the population to identify trends and its status; (2) Research the potential threats that may be
driving declines and take appropriate measures to reduce these; (3) Protect areas of important habitat
(BirdLife International 2014d).

29. Cinereous Bunting Emberiza cineracea (Near threatened)
©Mike Pope
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
This species comprises of two different races. The nominate race breeds on a number of islands in Greece
(such as Chios, Sykros, Samos) with between 100 and 250 pairs, and is also found in Turkey. E.c. semenowi
occurs more in Iraq and Iran (for example in the Zagros mountain range). It winters in a range of habitats in
north-east Sudan, Ethiopia, Eritrea, south-west Saudi Arabia and Yemen. Passage birds may be found in
Syria, Lebanon, Jordon, Israel, Egypt, Kuwait, Qatar, Bahrain and the United Arab Emirates.
MONITORING POPULATION TRENDS
Based on estimates of 2,600-7,800 breeding pairs in Europe and less than 100 pairs in Iran, the population
is estimated to number 5,400-15,800 mature individuals, roughly equating to 8,000-24,000 individuals in
total. Based on estimates of 2,600-7,800 breeding pairs in Europe and less than 100 pairs in Iran, the
population is estimated to number 5,400-15,800 mature individuals, roughly equating to 8,000-24,000
individuals in total (BirdLife International 2014).
CAUSES OF POPULATION CHANGE
Changes in grazing pressure by sheep and goats may affect the population size. High grazing pressure could
result in the trampling of nests whilst too little grazing could reduce the area of open feeding sites.
Remaining habitat in western Turkey is being developed rapidly for tourism. Suitable habitats in south-east
Turkey have been flooded by dam construction, resulting both in direct habitat loss and the relocation of
displaced villagers to new, currently unpopulated areas (BirdLife International 2014c).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Survey suitable habitat within the putative wintering grounds (Walther et al. 2004; Walther 2006); (2)
Develop a Species Action Plan; (3) Develop a monitoring programme to assess population trends. Assess
threats to the species and develop appropriate responses.

MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
Luscinia pectardens breeds in Sichuan, Yunnan and south-east Tibet, China, and is a non-breeding visitor to
the mountains of Arunachal Pradesh and Meghalaya, India, northern Myanmar and Bangladesh.
MONITORING POPULATION TRENDS
This species is very poorly known and the only recent records are from one site in China. Although the rest
of its possible range has not been well surveyed it is possible that the species is genuinely rare and
therefore it is perhaps best placed in the band 10,000-19,999 individuals. This equates to 6,667-13,333
mature individuals, rounded here to 6,000-15,000 mature individuals.
CAUSES OF POPULATION CHANGE
It has presumably been affected by deforestation from logging and agricultural expansion on both the
breeding and wintering grounds.
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1) Survey within its known breeding range to determine habitat preference and density estimates; (2) Use
these to identify other potentially key areas, survey these and generate population estimates; (3) Assess
the impacts of forest loss within its breeding and inferred wintering ranges using satellite imagery and
remote sensing; (4) Protect key breeding strongholds; (5) Collate available winter records and analyse
patterns of distribution and habitat use to improve knowledge of its winter distribution (BirdLife
International 2014).

31. Derbyan Parakeet Psittacula derbiana (Near Threatened)
© Douglas Janson
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
As of the 2011 IUCN Red List of Threatened Species its status was updated from Least Concern to Near
Threatened. Psittacula derbiana occurs from Arunachal Pradesh and Assam, India, to southern China,
including south-eastern Tibet, western Szechwan and western Yunnan (del Hoyo et al. 1997, Juniper and
Parr 1998.)
MONITORING POPULATION TRENDS
Local extinctions and locally falling numbers (Zeidler and Francis 2011) suggest that the species is in decline
overall. It is perhaps the rarest of all species of Psittacula in mainland Asia.
CAUSES OF POPULATION CHANGE
This species's population is suspected to be undergoing a moderately rapid decline owing due to trapping
for the illegal wildlife trade The species was formerly threatened by logging campaigns that resulted in the
loss of much breeding habitat; however, this threat ended in the 1990s (Zeidler and Francis 2011). Today,
old-growth trees, some of which provide nest-holes, are still felled for house construction and firewood,
even in protected forests (Zeidler and Francis 2011). Recent observations indicate that this species is
subject to heavy trapping pressure and egg-collecting for the pet trade (Zeidler and Francis 2011) where it
fetches a high price in the black market.
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Monitor population trends and trapping pressure; (2) tackle the threat of trade through the
enforcement of legislation and awareness-raising activities; (3) increase the number of sites that are
robustly protected; (4) Support monks that carry out wildlife protection activities (Zeidler and Francis
2011); (5) assess the effectiveness of a nest-box scheme (Zeidler and Francis 2011).

32. European Roller Coracias garrulus (Near threatened)
MIGRATION PATTERNS AND CONNECTIVITY ALONG PATHWAYS
Coracias garrulus occurs as two subspecies: the nominate breeds from Morocco, south-west and south-
central Europe and Asia Minor east through north-west Iran to south-west Siberia (Russia); and semenowi,
which breeds in Iraq, east to Kashmir and north to Turkmenistan, south Kazakhstan and north-west China.
The species overwinters in two distinct regions of Africa, from Senegal east to Cameroon and from
Ethiopia west to Congo and south to South Africa (BirdLife International 2014).
MONITORING POPULATION TRENDS
It has a large global population, including an estimated 100,000-220,000 individuals in Europe in 2004 (50-
74% of the global breeding range). However, following a moderate decline during 1970-1990, the species
has continued to decline by up to 25% across Europe during 1990-2000. Overall European declines
exceeded 30% in three generations (15 years). Populations in northern Europe have undergone severe
declines (Estonia: 50-100 pairs in 1998 to no known breeding pairs in 2004; Latvia: several thousand to
under 30 pairs in 2004, Lithuania: 1,000-2,000 pairs in 1970s to 20 pairs in 2004, and in Russia it has now
disappeared from the northern part of its range. Should this species be shown to be declining, it may
warrant uplisting it further to Vulnerable (BirdLife International 2014).
CAUSES OF POPULATION CHANGE
Threats include persecution on migration in some Mediterranean countries and thousands, are shot for
food in Oman and India every spring. The loss of suitable breeding habitat due to changing agricultural
practices, conversion to monoculture, loss of nest sites, and use of pesticides (reducing food availability)
are considered to be the main threats to the species in Europe. (BirdLife International 2014).
CONSERVATION TARGETS/ RESEARCH PRIORITIES:
(1): Continue monitoring population trends. Determine Turkish, Middle Eastern and Central Asian trends
and review its conservation status based on the findings; (2) Tackle specific threats such as hunting; (3)
Address threats in Europe relating to the Common Agricultural Policy and integrate appropriate measures
into agri-environment schemes; (4) Continue monitoring population trends; (5) Determine Turkish, Middle
Eastern and Central Asian trends and review its conservation status based on the findings; (6) Tackle
specific threats such as hunting; (7) Address threats in Europe relating to the Common Agricultural Policy
