Three skins. 



Fairly common over the lowlands of both the Caribbean and Pacific 

 and extending upward over the highlands, in less numbers, to an ele- 

 vation of perhaps 4,000 feet. Its habits are more like the North 

 American species of the genus, since it keeps more to the open wood- 

 land, isolated thickets, and second-growth scrub. They prey largely 

 upon birds. The specimen shot at El Hogar was feeding upon a 

 freshly killed cuckoo {Crotophaga stt/cirostris).

The White-tailed Buzzard is a rare bird in Costa Rica, but few 

 specimens having been recorded from that country. It appears to be 

 a resident of the higher portions of the country, but in small numbers. 

 It is much more abundant further north, especially in Mexico.
