Carriker : List of the Birds of Costa Rica. 789 



Carnegie Museum: Juan Vinas, April 18, 1907 (Carriker). 



The Bank Swallow is evidently not a common migrant in Costa Rica. 

 Very few specimens are recorded, and recent collectors seem to have 

 missed it or else it does not come there in any numbers. I saw a few birds 

 at Juan Vinas during April in company with Hirundo erythrogastra and 

 Stelgidopteryx serripennis, which spent their whole time either in feeding 

 over a meadow and along a road or else perched on a telephone wire. 

 There are no records for the lowlands, either of the Pacific or Caribbean, 

 and it is quite probable that the birds remain in the highlands.

This is the most abundant resident swallow in Costa Rica and is dis- 

 tributed over nearly the whole of the country wherever conditions will 

 permit of its presence. I found it very abundant at Boruca and Buenos 

 Aires, where it had been nesting in the grass-thatch roofs of the houses. 

 It is more partial to regions where open meadows are numerous.
