This species is confined entirely to the lower portions of the Pacific 

 slope, from Chiriqui to Guanacaste. It is most abundant around the 

 head of the Gulf of Nicoya. It is more or less a Avoodland species, 

 but does not go into the heavy forest, preferring the open woodland, 

 fringes of trees along streams, and second-growth scrub. I believe it 

 is the only Costa Rican hummingbird which I ever heard sing. On 

 one occasion at Buenos Aires I was attracted by a peculiar fine, sweet 

 song, unlike anything I had ever heard before, which upon investi- 

 gation proved to be from a male of this species, perched on a twig 

 high up in a tree and singing away as though perfectly oblivious to 

 his surroundings. His bill was pointed upward and as he sang his 

 throat swelled and quivered, while his head moved . from side to side 

 as though lost in the ecstacy of the song.

Although this Agyrtria was generally supposed to be found in Costa 

 Rica, I have been unable to find a single record for the actual taking 

 of specimens there, with the single exception of the birds taken by
