The Big Sit!® 2020 All eBird checklists from The Big Sit! held
on October 10 and 11, 2020, have been received. We have clear
winners.
We have seen the Facebook pictures and posts. To be sure,
everyone had a good time.
The Big Sit! was started by the New Haven Bird Club 1992. Nine
years later Birdwatcher’s Digest took over management of the event
and with their resources grew the event to 234 circles in ten
countries. Due to changes at Birdwatcher’s Digest, management of
The Big Sit! was given back to the New Haven Bird Club this
year.
We are a small club and had to use a combination of approaches
to keep The Big Sit! going. We built a website to inform the
participants, we used eBird for data handling and Facebook for
comments, chats, and photos. Many organizations still use The Big
Sit! to raise funds for conservation. Most importantly it was the
circle compilers and participants who jumped in to keep the
tradition alive.
eBird added an important aspect to The Big Sit! It offers a
simple user interface, an ease of effort tracking, an ability to
capture GPS coordinates and location management, and accessibility
to the data that could be invaluable to scientists studying bird
migration on a continental scale. Data can be exported from eBird
and shared as a spreadsheet. Please let us know if you would like
this year’s data; email us at [email protected].
This year The Big Sit! had three countries participating: Costa
Rica (one circle, 47 species), Guatemala (three circles, 147
species), and the United States of America (98 circles, 358
Species). Hopefully in the future we can attract Big Sit! circles
in other countries and on other continents.

Some Unique Approaches
Friends of Goose Pond in Indiana did two Big Sits. One was
actual (as per normal rules). The other was virtual through Zoom
and FaceBook Live. Due to social distancing, they could not invite
folks like they normally do. They broadcast on Zoom for 12 hours.
They had birders on property connected via Zoom sharing scope
views. Remote viewers also tuned in via Zoom and see the actual
"Big Sitters" and see what the virtual "Big Sitters" were seeing.
Viewers could hear the conversations, stories etc.
Snacks
The Big Sit! is nicknamed the “Tailgate party of birding.”
Tailgating means food is involved. So next year let’s see how each
circle does snacks. Here are few photos from Connecticut.

Moving Forward
This was the New Haven Bird Club’s first year back with managing
The Big Sit! We all had challenges with the COVID-19 pandemic. We
think we are off to a great start. We hope to see the event expand
to more circles in more states and countries. Please let us know if
you have ideas on how to improve the event by emailing
[email protected]. Together we can continue the fun and
provide a very important snapshot of bird distribution during the
October migration.

Circles Ranked by Number of Species (Bragging Rights for Best
Overall Count and Best State Count)
For the purpose of The Big Sit! Bragging Rights, the checklists
from each circle were ranked based on the number of eBird Species
in the submitted eBird report. We hope to modify the Rules for The
Big Sit! next year to adjust for our use of eBird as the reporting
system.
