Carriker : List of the Birds of Costa Rica. 545 



or it may be only a case of aberrancy. All specimens with such a 

 tendency are slightly immature birds, with the bright crown- and 

 throat-feathers only partially assumed, and it may be that with the full 

 development of these feathers they assume the normal shade of color. 

 This species is found over the Caribbean lowlands, the plateau 

 region, and southwestern Costa Rica, from Pozo Azul southward. It 

 is particularly abundant in the Terraba Valley, where it feeds on the 

 flowers of the " guava ' ' tree in company with Saucerrottia niveiventris 

 and others. It is difficult to secure males in full plumage, nearly all 

 birds secured lacking some or all of the brilliant feathers of the throat 

 or crown. It is not a bird of the forests, but lives in scattered trees, 

 along rivers and roadsides. It is a very swift flyer, even' for a hum- 

 mingbird, and as a rule feeds high up.

This Floricola seems to be confined to the region of the central 

 plateau and Guanacaste, from the Tempisque River up to about 2,000 

 feet on the Volcan de Miravalles. I have never seen it in the Carib- 

 bean lowlands, nor in the southwestern part of the Pacific lowlands, 

 where it is replaced by F. superba superba. Like the other species of 

 the genus, it keeps more to the open, in gardens and pastures.
