The Lesser Cliff Swallow is a very rare winter resident in Costa Rica, 

 the capture of but few specimens being on record. Mr. Bangs has one 

 specimen, and I secured but one. It seems to be found only in the high-

The Gray-breasted Martin is found over the whole of the central high- 

 lands and the Pacific slope and lowlands, but is rare or wanting on the 

 lower parts of the Caribbean watershed. Its habits are the same as those 

 of the Purple Martin of North America.
