"In the series taken during the fall there is only one adult male, the 

 remainder being either adult females or birds in first winter plumage. It 

 is not clear how long this latter dress is worn, but it is probable that it 

 persists through the first breeding season. One specimen (25750) from 

 Carrillo, August 14, 1905, is emerging from the juvenal plumage, which 

 is dull olive-yellowish below, quite different from the next stage." (W. 

 E. C. Todd.) 



This bird ranges over the whole of the central plateau from 3,000 to 

 8,000 feet. It is inclined to be gregarious when not breeding, and is found 

 only in the heavy virgin forest, usually at a considerable height from the 

 ground. It has a weak, rather musical note, which is often repeated while 

 feeding or moving through the tree-tops. Males in full plumage are not 

 common, the birds probably not attaining the adult phase until the second 

 or third year. When fruit is scarce at high altitudes it frequently descends 

 as low as 1,200 feet, specimens having been taken at Carrillo in August, at 

 La Hondura in September, on Irazu at 8,000 feet in April, and at Ujurras 

 de Terraba at 7,000 feet in September.
