Both specimens were noted as having enlarged, active gonads when 
collected, indicating that the ‘immature’ male may well have been 
fully adult, as there is nothing in its plumage to indicate youthfulness.

These specimens considerably extend the previously known range 
of this cuckoo. All of them are deep brown above and gray below, 
with the under surface of the rectrices (except the middle pair) black, 
tipped with white. The one from San Antonio is lighter brown above 
than the others and so shows a slight approach to columbiana. All 
are very distinct in appearance from the specimen of columbiana 
taken at Soledad, and they differ from P. c. cayana in being slightly 
darker brown above and in having the under tail coverts lighter.

One of the April birds was noted as having enlarged active gonads 
when collected. 
The Cucuhy bird is slightly paler than any of the others and has a 
slightly shorter bill, suggesting in these characters an approach to the 
race ochracea Cory, known from Yurimaguas, Peru. It cannot be 
considered as belonging there, however, for it has these characters
