The Western Grebe is an elegant North American waterbird that is found breeding south into northern and central Mexico. The species 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 greenish bill. Western Grebe can be separated from the similar Clark's Grebe by its duller bill color, darker face, darker back and flanks, and thicker hindneck stripe. The species is famous for its elaborate courtship display, where pair members mimic each other in a beautiful dance.
