A Quick Look at Spring Migration Bird Collision Figures

Summer intern Kaitlyn Parkins presents data on spring migration bird collisions collected by Project Safe Flight volunteers

 

Every year, more than 100 species of migratory birds pass through New York City on their way between South and Central America and their northern breeding grounds   along the Atlantic Flyway. The trek through the City can be perilous for these birds because of the maze of tall buildings, bright lights, and reflective glass.

 

Since 1997, NYC Audubon has sponsored Project Safe Flight (PSF), an endeavor to study and mitigate urban bird collisions. Working with a devoted group of volunteers who patrol high-risk locations during migrations, Project Safe Flight counts and collects birds that have been injured or died in building collisions. To date, over 6,000 birds of 126 different species have been found and documented in PSF’s database.

This spring, eight sites were monitored, and a total of 39 dead and five injured birds were found by volunteers. Of those, 29 were identified to the species. Just like previous years, common yellowthroats and ovenbirds were found more frequently than any other species; they were followed by white-throated sparrows, American woodcocks, and black-and-white warblers. The majority of collisions occurred at Bryant Park and the Metropolitan Museum of Art.

 

We will include this year’s data with our records from 1997–2012 and analyze it to help us better understand why bird collisions occur, and what can be done to reduce their frequency. Soon, volunteers will be gearing up for the fall migration. If you’re interested in volunteering for this important project please contact our outreach manager at apalmer@nycaudubon.org.
