The Clark's Grebe is a lovely North American diving waterbird that is found breeding south into northern and central Mexico. The species, along with Western Grebe, is resident in some areas of Baja California and the central Mexican plateau, and numbers are augmented in winter, especially on the Pacific Coast, by migrants from more northerly breeding populations. It is a striking bird, long-necked and thin-billed with black above and white below and a yellow-orange bill. Clark's Grebe can be separated from the similar Western Grebe by its brighter bill color, whiter face surrounding the eye, paler back and flanks, and thinner hindneck stripe. In most places, Clark's Grebe is outnumbered by the closely related Western Grebe, and hybrids between the two species are known.
