The Pond in the southeastern corner of Central Park had a Green Heron on Sunday. It was fishing for minnows when I found it on the far shore of the southwest corner of the pond. Fall migration has begun slowly in the park. Number are still very low, but we're getting interesting birds. The highlights of the day for me were a Ruby-throated Hummingbird, Canada Warbler, two Northern Waterthrushs, American Redstart, Belted Kingfisher, Great Egret and Baltimore Oriole.
