Carriker : List of the Birds of Costa Rica. 519 



Glaucis hirsuta ceneus Bangs. Auk, XXIV, 1907, 295 (El Pozo de Terraba 



[Underwood]).

Three skins. 



Upon comparison of Costa Rican birds with Colombian, the differ- 

 ences pointed out by Mr. Lawrence for his G. csneits become apparent 

 at once, and I thoroughly agree with Mr. Bangs in setting up Law- 

 rence's name for the northern race of G. hirsuta. 



This form ranges over the whole of the Carribean and Pacific low- 

 lands, but in small numbers, never being abundant, as are the other 

 species with which it associates (see notes on preceding species). I 

 do not believe it is found above 1,000 feet. Its habits are the same 

 as those of the preceding bird.

This handsome hummingbird is pretty well distributed over the 

 Caribbean and Pacific watersheds ; on the Caribbean side it is found 

 between 1,500 and 3,500 feet and does not mix with P. longirostris 

 longirostris of the lowlands, while on the Pacific slope it is found not 

 only at the higher altitudes but also mixes to a small extent with its 

 relative of the lowlands. It is strictly a forest species, as are all of 

 the genus, preferring the dark cool depths of the heavy forests of the 

 Caribbean slope to any other part of Costa Rica. They also feed largely 

 on several species of " Wild Plantains" found in the higher altitudes.
