Деталі спостереження
Pluvialis plovers, more slender than Black-bellied with relatively smaller heads, thinner necks, and slender bills. Wings extending well beyond tail tip and lots of primary extending beyond tertial tips, but I couldn't count how many. Bold supercillia setting off contrasting dark caps. "Contrasty" gold and dark speckled upper parts. Delayed pre-alternate molt also consistent with this species; Pacific Golden-plover (which I'm not sure we really need to consider) undergo pre-alternate molt early in spring, usually/often prior to migration. Black-bellied Plovers typically molt earlier in the spring, and the several hundred I saw this same morning at AIC were all in alternate plumage.
