Chorlito Pechinegro Erythrogonys cinctus

Attractive plover, but contrary to its name, it does not have red knees. Instead it has pinkish upper legs. Adult has solid black hood and white chin with a black breast-band and chestnut flank patch. Juvenile is gray with white underparts lacking the black or red. Fairly common resident around freshwater wetlands, where it often occurs in small flocks.
