• Disturbances (caused birds to flush)
2011-2012 FSD Report
• Roving chicks:
– 1623 observations (seabirds/shorebirds,
all ages)
– Useful for:
• Identifying brood-rearing areas
• Statewide productivity estimates (need
counts during count windows)
• Precise local counts (need intensive local
monitoring)
• Estimating distance from natal nest
2011-2012 FSD Report • Rooftops:
– 5 species nesting on rooftops
– Found in all regions (exc. Big Bend); maps in report
– 66% outcomes unknown or not reported

2011-2012 FSD Report
• Conclusions: – Incredible increases in effort!
– Route surveys during count windows are critical
for determining population numbers, trends, and
progress towards objectives.*
– Weekly monitoring of active sites is very
important to estimate peak numbers (nests &
chicks) and nesting outcomes.*
*Important goals for regional partnerships!

What’s to come
• Quality control of 2013 data
• FSD will reopen for data entry March
2014 (always open for data retrieval!)
• FWC will seek funding to
continue/expand training and quality
control
Thank you all for your participation in
Florida’s shorebird monitoring program!
