The Tiny Hawk is among the most poorly known members of its genus in the Neotropics. Name for its diminutive size, the male Tiny Hawk is only about 75 g although females exceed 100 g. With relatively elongated toes the Tiny Hawk is highly specialized for preying on birds. Though it will likely take all manner of small avian quarry, it has been known to concentrate on hummingbirds, which it will either still-hunt or actively check perches used by the hummingbirds in their courtship display. The Tiny Hawk is distributed throughout tropical South America in humid lowland forest on both sides of the Andes, Panama, the Guianas and throughout Amazonia and to the southern and eastern coasts of South America. Despite its large range, it is seldom encountered and is poorly known, with very little data on its behavior and or its breeding.
