Rather an abundant bird over the greater portion of Costa Rica, 

 but especially on the Caribbean slope and central plateau region. I 

 saw one flock in the Terraba Valley, which were flying just behind a 

 large flock of Streptoprocne zonaris zonaris, over the open " sabana. " 

 Underwood also took it farther up the Rio General de Terraba. 

 Little or nothing seems to be known of the habits or breeding of this 

 or any other of the family in Costa Rica.

Bangs Collection : San Pedro del Mojon, Buenos Aires de Terraba 



(Underwood). 

 Carnegie Museum : San Jose and San Pedro del Mojon (Underwood). 



There are but few Costa Rican records for this species, but with 

 the exception of one from Buenos Aires, all are from the vicinity of 

 San Jose, from which we might infer that the bird is more partial to 

 the upland portion of the country than the lowlands. It has not 

 been taken at all on the Caribbean side.
