Carriker : List of the Birds of Costa Rica. 819 



This common warbler is found in winter in almost every part of Costa 

 Rica, from near sea-level up to not less than 7,000 feet (Ujurras de Terraba). 

 It never appears to be numerous in individuals and is always seen alone.

As is generally the rule with species covering so wide a geographical 

 range as the present, it is found in almost all parts of Costa Rica from 

 sea-level up to 4,000 feet, and perhaps higher, on the Pacific as well as the 

 Caribbean slope, but is not at all common in the region of Guanacaste or 

 Nicoya. It does not associate in flocks so much as the other species of 

 the family, being in this respect more like Diglossa plumbea, although 

 often found in company with other species of honey-creepers, vireos, and 

 small tanagers. It is seldom encountered in the heavy forest, preferring 

 open woodland, low trees, and shrubbery.
