..a Dunlin (in between breeding & intermediate plumage), taken a month ago, that part of the beach is closed now..
Dunlins are sparrow-sized sandpipers with long, black, droopy bills and relatively long, black legs. In breeding plumage, Dunlins are comparatively easy to identify because of the conspicuous black belly patch and rufous cap and mantle. In the nonbreeding season, they are plain gray-brown on their upper parts and white below. A prominent white wing stripe, seen in flight, is present in all plumages.
