Temminck's Lark
Eremophila bilopha
Unlike most other larks, Temminck's lark is a distinctive looking species on the ground, similar to the other, larger, member of its genus, the horned lark. The 14 to 15 cm (5.5 to 5.9 in) adult is mainly reddish brown-grey above and pale below, and it has a striking black and white face pattern and a distinctive black patch on its breast. The summer male has black "horns", which give this species its alternative name. The juvenile of this species is reddish above and pale below, quite unlike the juvenile horned lark.
