Brown Falcon

Overview

The brown falcon (Falco berigora) is a relatively large falcon native to Australia and New Guinea.
A number of plumage morphs occur, with the primary distinction being between the pale morph and the dark morph. Both morphs usually have dark brown upper parts and wing coverts. Dark morph birds have predominantly dark under parts, although some light streaking is common.
