Welcome to the BirdForum Opus

The interactive birding encyclopaedia

Welcome to the Opus, an interactive, multimedia encyclopaedia that anyone can edit. You can use the Opus to find out about everything to do with birds - from the birds themselves to the places you can find them.

Identification

A bulky hawk with a short white tail with a black sub-terminal band.
The common pale morph has white underparts and rump, dark gray back and rusty-colored shoulder patches. The rarer dark morph is, except for the tail, almost entirely brownish-black.
Juveniles are mainly blackish with variable whitish markings on the underparts and head.

Distribution

South-eastern Texas, through Central America, and most of South America east of the Andes as far south as central Argentina. It is absent from densely forested regions (e.g. most of the Amazon).
