The Semicollared Hawk is a small, rare hawk of the Andes. It occurs from Colombia south to Peru in cloud forest at intermediate elevations. Adults are slate gray above and white below with heavy black barring. Immatures are either brown or rufous. Similar to the Tiny Hawk (A. superciliosus) of lower elevations, the Semicollared is unique in having a pale nuchal collar and generally a pale, streaked cheek giving it something of a hooded appearance. It is very poorly known, and there is no available information on its feeding or breeding behavior.
