Dunlin (Crop).

Although I can't prove it, perhaps this is the same Dunlin I saw the month prior? In the previous photo, the bird was still mostly in breeding plumage, although showing signs of moult (Especially on the belly), whereas this bird is in a nearly completed winter plumage. Who knows, maybe it stuck around to grow in its feathers?
