Irondequoit Bay Outlet Bridge - March 3

Mary Flood and I birded the Irondequoit Bay Outlet Bridge over the noon hour today. Unlike Tuesday when the place was largely deserted of migratory species, today there was an excellent variety and large numbers of waterfowl. The channel north of the bridge was empty, but the tip of the bay south of the bridge was packed with many birds coming obligingly close for good pictures. :-) There was an abundance of Redheads, perhaps 50+. I was able to get a number of pictures with a Greater Scaup and a Lesser Scaup side-by-side so that the differences became evident. Mary saw three American Coots at the outlet bridge on Tuesday and today we found five. We only saw one each of Red-breasted Merganser, Long-tailed Duck, and (immature) Great Black-backed Gull. Finally, we saw three Trumpeter Swans. We looked for Canvasbacks with no luck. Great midday outing!

Just out of shot to the left, someone is throwing corn to the birds, hence the big bird party!

Mute Swan wondering if I had any corn!

Swan Goose. These were Mary's favorite birds of the day. These are domestic geese that have become feral.

Redheads: female (front), male (back)

Greater Scaup (left), Lesser Scaup (right). There are a number of subtle differences between these two ducks, but the most obvious one in this picture is that the side of the Greater Scaup is pure white, while the side of the Lesser Scaup is not.
