Andean Flicker

The Andean flicker is about 32 cm (13 in) long. Males and females have the same plumage except on their heads. Adult males of the nominate subspecies are dark slate gray from forehead to hindneck; the last occasionally has a hint of red. Their face, chin, and throat are pale buffy white with a thin black malar stripe with red tips on the feathers. Adult females have an all-black malar stripe and never any red on the hindneck. Both sexes' upperparts are barred with brown, light brown, and buffy white; their uppertail coverts are white with narrow dark bars. Voice: The Andean flicker has a large vocal repertoire. Its most common calls are "a loud, piercing kweeir...and a loud tew-tew-tew". Males display with a "kwa-kwa-kwa, wee-a, wee-a or kway-áp call". They also make "single or grouped peek or kek" calls that are thought to be for contact or alarm, and "a clear descending trill, brrrridip" that is thought to be for long-distance communication.
