I finally caught up with the Peregrine Falcon that likes to sun on the north edge of the Reservoir in Central Park for the first time this winter. We had a pair in the same tree last year, and a single Peregrine the year before. This one was very vocal. I couldn't see what it was concerned about, but if it was like last year, it was most likely a Red-tailed Hawk.
It's nice to have the Peregrine back. The low tree branch the bird perches in gives great looks at the bird.
