The picture of these Greater Yellowlegs in flight was taken at the Jamaica Bay Wildlife Refuge. I took this picture with the CANON EOS7D with a CANON 100-400mm lens.
This was taken at the north side of the East Pond at the Jamaica Bay Wildlife Refuge in the evening light. The East Pond water was lowered for the Shorebird Migration making it easier to enter though the north part of the pond. It is a beautiful vantage point to see the pond and taken advantage of the setting sun.
