This species is nearly allied to the Red-tailed Hawk of North 

 America, and the Buteo Jackal of South Africa, but from both of 

 these it may be distinguished by the jet-black colouring and by its 

 more lengthened bill. During flight the white at the base of the 

 primaries is very conspicuous, and is strikingly contrasted with the 

 black of the chest and the brown of the other part of the wings.
