The White-collared Kite is restricted to Alagoas and Pernambuco states in northeastern Brazil. It resembles the widespread Gray-headed Kite (Leptodon cayanensis), the two sharing relatively large size, dark gray upperparts, and white underparts. The White-collared is unique in having a white collar wrapping around the hindneck, a single pale tail band, white spotting on the mantle, white tips to the secondaries, and white underwing coverts. The behavior of this species is very poorly known, although it likely is similar to that of the Gray-headed. It resides in Atlantic coastal forest, which is heavily threatened by habitat destruction. This species is extremely poorly known - even its status as a species was in doubt until recently - and is of significant conservation concern, although population data are still limited.
