Squatarola heterotica. January 30, 1911. The plover which I obtained last May in high plumage is now in a mixed plumage, still showing considerable black in the underparts. Its food has been the same as that of the Turnstone, aside from worms, etc. which they both hunt very energetically. February 5, 1911. The plover is evidently moulting slowly and I think has most of the winter-plumage back feathers, although there are a good many black feathers in his underparts. In hunting worms the plover will stop suddenly with head down, and then make a very quick jab with his bill, into the ground. If he gets the end of a worm he keeps up a steady strain until it worm is pulled out. February 12, 1911. Black feathers in the underparts of the plover are becoming scarcer. Feb. 19, 1911. I'm practically full winter plumage. Looks "spick and span." New primaries have put in appearance on the unspunioned wing; look very black compared to old ones.
