 Terraba between Palmar and Lagarto, which were nesting in the rocks. 

 Mr. Cherrie also mentions this colony as having been there in 1892 (Expl. 

 Zool. en C. R., 1890-1, 1893, 16). After the breeding season they spread

The Barn Swallow is a common migrant over the whole of the plateau 

 and both slopes. In fact it is found over the whole country wherever 

 there is sufficient open ground to give feeding places. I saw it at Juan 

 Vinas until about the last of April, 1907, when it disappeared. It is 

 more abundant in the highlands than in the low, hot regions.
