The NW corner of Cell 1 is drying out quick. A pair of Great Egrets, a handful of Killdeer and Least Sandpipers were foraging the remnants of the pond that is now low enough to show several large Common Snapping Turtles.
I scanned shorebirds at this point and could only pick out a few Greater Yellowlegs among the 100+ Lesser Yellowlegs and 200+ Least Sandpipers.
Here are some comparison shots of both the Little Gull and Bonaparte's Gulls from the same distance. Physically there is very little difference to tell them apart, but some of the Bonies show brown tail and wing tips, while the Little Gull showed black. Some of the Bonies started showing white tips to the primaries. Caps varied from all white to partial to full, with the earspots coming in. On the Little Gull the cap extends lower onto the back of the head. The bird never stretched its wings so I could not look for dark underwing linings. In these pics the Little Gull shows the appearance of almost no neck, which might be diagnostic against the longer-necked appearance of the Bonaparte's Gulls.
Let the shorebird season begin!
