friend.

This beautiful species is evidently sparingly distributed over nearly 

 the whole of Costa Rica, excepting the higher portions of the moun- 

 tains. It frequents the more open woodland, soars a great deal, and 

 likes to perch on the very top of tall trees, like Leucopternis ghies- 

 breghti, for which it might easily be mistaken if the back were not 



visible.

Carnegie Museum : El Pozo de Terraba (Carriker). One skin. 



Although there is a record of the taking of this species at Jimenez, 

 in the Caribbean lowlands, I believe it to be merely a straggler on 

 that side, and that its true range in Costa Rica covers only the central 

 plateau region and the Pacific slope to the coast, including Guanacaste. 

 It is much more abundant than the other representative of the genus 

 in Costa Rica (S. tyrannus), but yet is not by any means a common 

 bird, for in all my collecting I saw only two individuals. It is 

 Buteo-like in its habits and manner of flight, and perches in large 

 trees in conspicuous places as do the Buteos.
