Caatinga Black-Tyrant

A common and widespread albatross of the southern oceans; often seen from shore and ferries. Like other albatrosses, often scavenges at fishing boats. All plumages white-headed, often obvious at long distance (black brow only visible at close range). Adult has orange-yellow bill, brighter at the tip and thick black irregular underwing margins; 1st-year has dusky bill with black tip and solidly blackish underwings; mostly like adult in 3 years.

Breeding males are mostly black with a long tail. There is a large yellow-and-buff patch on the shoulder. Females and non-breeding males are streaky and brown, though males retain their colorful shoulder. Found locally in montane marsh, heath, and grassland. Vocalizations include low rasps and twittering and sizzling calls. Male separated from Marsh Widowbird by its more extensive buff shoulder patch. Female can be confused with several other species, but is usually identified by association with buff-shouldered males.

Scarce and local throughout its range, and rarely encountered. Found in varied scrubby montane habitats, especially Polylepis groves. Feeds in shrubs and on the ground, often in pairs and small groups; associates readily with other siskins. Both sexes resemble the much commoner and more widespread Hooded Siskin (absent in central Chile), but Thick-billed Siskin is stockier with a relatively large, deep bill. Varied songs and calls overall rather similar to other siskins.
