The Collared Forest-Falcon is the largest member of its genus. It occurs in a wide variety of tropical forested habitats from central Mexico to southern Brazil. The Collared Forest-Falcon typically prefers humid lowland rainforest but can be found in semi-deciduous, deciduous and riparian forests in the more arid parts of its range. It is a distinctive species, with three color morphs: pale, dark and tawny. The pale and tawny morphs exhibit the pale collar across the back of the neck for which the species is named; this collar contrasts strongly with the black upperparts. The species is often  ommon and is identified easily by its distinctive humanlike ‘aw’ notes, though it is generally harder to see than hear. The Collared Forest-Falcon feeds on a variety of small mammals and birds in the interior of forest which it appears to locate by hearing, though it has been known to run prey down on the ground.
