The immature birds of this species exhibit a peculiar phase of 

 coloration, having the whole of the throat, sides of neck, chest, and 

 upper breast suffused with chestnut-rufous, much the same color as the 

 lower parts in Rhopoctites riifo-brimneus. 



The Costa Rican range of this species is practically the same as that 

 of the preceding, also the habits and habitat. Neither are common 

 birds, the present species probably being the rarer of the two.
