Chilean hawk
species of bird
The Chilean hawk (Astur chilensis) is a bird of prey species belonging to the family Accipitridae. It was formerly placed in the genus Accipiter. It breeds in Andes forests from central Chile and western Argentina south to Tierra del Fuego, from sea level to 2,700 m altitude (though birds are rarely observed above 1,000 m). Some winter apparently in the lowlands of NW Argentina.
It is sometimes considered to be a subspecies of its northern relative the bicolored hawk (Astur bicolor), including by the American Ornithological Society and sometimes a distinct species. The two show differences in habitat preference and have allopatric distributions. But the situation is complicated by the subspecies pileatus, which is intermediate in plumage between bicolor and chilensis, and has been variously assigned to either species by those that consider them distinct.
Description
The male is 37 to 38 cm long, while the larger female measures 41 to 42 cm. The adults have black upperparts, and an ash-grey chest and abdomen with dark barring. The throat has longitudinal dark stripes and the undertail is white.
This brief starts where responsible research should: with the source description of “Chilean hawk” as species of bird. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of bird. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q114022. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
