Some more info about this morning's bird. I believe people who left Sandy Point before about 9 or arrived after about 10 missed it (high tide at 8:30). Thanks to Steve Grinley for getting word to at least some of those who'd left early. It spent most of the hour at the top of the cove to the west of the point but was last seen on the ocean side before flying off to the south.
Everyone present was confident that we were looking at the same bird Suzanne Sullivan photographed yesterday. Compared to Semipalmated Plovers in the vicinity it was somewhat larger (more distinctly larger in flight) and heftier, wider white wing stripe seen in flight, longer bill, brighter legs, no yellow orbital ring, more contrast and clearer border between head and face, more conspicuous supercillium, broader and more uniformly shaped breast band. It did appear to vocalize but too much distance and background noise kept me from hearing it; maybe others had better luck. Others took lots of photos that I expect we'll be seeing soon.
It isn't a hard bird to find amongst SEPLs if you know it's there but not everyone would think to look for it in the first place; congrats and thanks to Suzanne for looking.
Otherwise a wonderfully birdy day on the Island with tons of warblers and other migrants in the trees at the Pines and Hellcat. No Little Gull seen in a quick scan at Joppa Park on the way home.
