Although there are quite a number of records for the taking of this 

 bird in Costa Rica, I do not believe it to be very abundant. It is 

 restricted to the higher parts of the central plateau and the high 

 mountains. I saw a fine adult bird on the Volcan de Turrialba in 

 October, 1907, but was unable to secure it.

Four skins. 



The most abundant and widely spread of the migrant species of 

 hawks in Costa Rica, being found in the lowlands of both the Ca- 

 ribbean and Pacific, and over the central plateau region. It seems 

 quite partial to trees along the edges of streams and isolated patches 

 of woodland.

A rare species in Costa Rica and confined to the higher portions of 

 the plateau region, as far as can be determined by the records known. 

 I do not know whether it is a resident there or only a winter visitor,
