We left Sunday afternoon and found out that the bird flew off about 15 minutes before we got there. We stayed until dark, but the bird never returned. So, we drove back over on Monday and got there just after sunrise. We watched and waited until 1:00 and the bird never showed. After spending a total of about 11 hours there over two days, we dejectedly headed back home. Then, as we were crossing the Verrazano Narrows bridge, we found out that the bird had returned to the very spot we just left! We turned around, headed back, and finally got to see this interesting gull. If accepted, this bird will represent only the 2nd record for the United States.
We had many other interesting sightings from Coney Island, but most of them were not bird-related and probably cannot legally be posted here.
