314 SWALLOW. 



Inhabits South America : found at Brazil and Cayenne ; also 

 Jamaica. — Sloane observes, that it is only there for six months, as the 

 Swallow in Europe, frequenting the Plains and Savannas of that 

 Island ; now and then alighting on the tops of shrubs. 



48 —SUPERCILIOUS SWALLOW. 



Hirondelle a Croupiou blanc, Voy. d'Azara, iv. No. 304. 



LENGTH five inches and a quarter. Plumage above blue black; 

 under parts from chin to vent white; rump white, and a trace of the 

 same over the eye ; tail a trifle forked. 



Inhabits Paraguay, near the Settlements, and chiefly seen in 

 pairs, rarely ten or twelve together; builds in October, in some hole 

 of a post or tree, the nest made of leaves and hair, and the entrance 

 so small, that the young cannot be easily taken therefrom. On the 

 River Plata, where no trees are, they build in the holes of banks, 

 made by their own efforts, in the manner of our Sand Martin.
