The pigeons in union square, washington square park, and Columbus circle are all very well socialized. Go to pet co and get a big bag of seeds (or just some bread) and get out there… you can have a cute photo op and also they’re nice. they are nice and they are beautiful, is the main thing. They will not give you diseases even if they land on you!
Also the high line, the MAD museum, the folk art museum, and the met Are all good places to go, if you don’t want to feed pigeons
