New York City has a large population of Peregrine Falcon's. My favorite pair has a scrape on Broadway Bridge, easily accessible by the 1 subway train. It's the Marble Hill-225th Street stop. The bridge is a drawbridge over the Harlem River and allows you some of the closest views of Peregrine Falcons in the city. This year, their scrape is situated so that you can see the eyasses being fed.
