Seen about a week ago in Central TX, probing around a stretch of shallow water in a river. I know there's a Greater Yellowlegs, and I believe the little fellows are Least Sandpipers. But I'm really not sure what the others are. They're the medium-sized ones that are present, and not flying, in both photos. Is there enough detail to identify them? I imagine there are half a dozen little things that can be used to tell them apart from other species, like many similar birds seem to have, but I don't know what those particular little things are.
