"Doubtless this species breeds in the immature (first winter) plumage, 

 as is shown by specimens from Miravalles taken May 30, which are 

 assuming the fully adult dress by a complete postnuptial moult." (W. 

 E. C. Todd.) 



Excepting only Enphonia minuta humilis, this is the commonest and 

 most widely distributed of the Euphonies in Costa Rica. It is found 

 over the plateau region, the whole of the Pacific slope and the Caribbean 

 slope down to the foot-hills, even descending into the lowlands in December 

 and January. It is most abundant on the Pacific slope at an elevation 

 of about 1,000 to 1,500 feet. It is found more in the open woodland and 

 scattering trees such as are found along roadsides and river banks. 

 It is very fond of the berries of the mistletoe, locally known as "Ma- 

 tapalo." It has a weak musical note, very hard to locate.

 ocean. There are no records for its presence south of the Gulf of Nicoya
