Campo Flicker
Colaptes campestris
The campo flicker is about 30 cm (12 in) long and weighs about 150 g (5.3 oz). Males and females have the same plumage except on their faces; males have a red malar stripe and females a black one. Adults of both subspecies have a black crown and a yellow face with white around the eye. Subspecies campestris has a black throat and campestroides a white one, their only difference. Both subspecies' upperparts are brown with dull white bars; their rump is white with a few narrow dark bars. Their flight feathers are brown with yellow shafts. Voice: The campo flicker has a large vocal repertoire. Its song is a "rapid 'wicwicwic---'" repeated 10 to 12 times. Calls tend to be high, sharp, and nasal: "tih", "tir", or "wur". Pairs duet with a "high 'wicwicwic' immediately answered by low 'wucwucwuc'."
