516 BIRDS OF THE REPUBLIC OF PANAMA PART 4 



13 days and the young are hatched blind, with sparse g*ray down, and 

 red mouth linings. They are fed by both parents, although primarily by 

 the female, on a diet of fruit and insects. At 11 days the nestlings are 

 nearly fully feathered and at 14 days they leave the nest. In Costa 

 Rica, the nesting season seems to end in June; there is no evidence of a 

 second brood.
