The range of this species extends over the Caribbean slope from an 



altitude of about 2,000 to 4,000 feet, but it is never a common bird. 



It is always found in or near the forest, coming out to feed along the 



edges like the preceding species.

I did not meet with this species and know nothing about its 



habitat more than that it has been collected in Costa Rica in the 



Dota Mountains, probably extending from there down through 



Chiriqui. It probably has about the same range as does Eupherusa 



egregia on the Pacific slope.
