This species ranges over the whole of the Caribbean lowlands, up 

 to about 2,000 feet and on the Pacific slope from the middle of the 

 Gulf of Nicoya northward to Nicaragua. It is much more abundant 

 on the Caribbean side, and seems to have crossed the low divide along 

 the southern side of Lake Nicaragua, thence passing southwards. 

 Its habits are the same as those of the preceding species. The birds 

 are always seen in pairs.

We have but two records for the occurrence of this form in Costa 

 Rica, the specimen taken by Boucard in 1878 and another by Under- 

 wood in 1908. It is evidently only a rare straggler in Costa Rica, 

 that country being south of its range. Its habits are similar to those 

 of the preceding species.
