I have never been good with shore birds. Part of that is because I don’t see them often, but also they are very confusing.
I photographed this one recently, and have been trying to figure it out. I am leaning toward the Solitary Sandpiper (Tringa solitaria), but that diagnosis depends on the legs being green, and they look more yellow-grey in this picture. The Solitary Sandpiper is not native to this area, but it could have been passing through in spring migration.
On purely a name basis, I think that it would be nice if it were a Semipalmated Sandpiper (Calidris pusilla), because “semipalmated” sounds cool.
As far as I know, there is no Fully Palmated Sandpiper.
