The females of this species are very like those of P. cinnamomeus, and are only 
to be distinguished by their smaller size; the males of course are widely different, 
being cinereous above and white beneath, instead of wholly of a cinnamon colour like 
the female. : 
P. cinereus has a wide range along the northern portion of the South American 
continent. It just enters our fauna, occurring along the line of the Panama railway, 
‘but not, so far as we know, farther to the westward.

It is now generally considered that the sexes of this species are alike in coloration, 
and differ only in the form of the second primary, which is much reduced in size in 
the male but normal in the female. At one time it was believed that all these 
cinnamon-coloured birds were either young birds or females of a species having a 
black or cinereous male ; against this supposition is the fact that no such male has yet 
been found in Central America north of the Isthmus of Panama, whereas the supposed 
females and young birds are common in many places up to the confines of Mexico. 
The probability, therefore, is that P. cinnamomeus isa distinct species in which the 
sexes are similarly coloured. 
Though this species is common in the forest-region of Vera Paz and the adjoining 
parts of British Honduras, it is absent from all the low-lying lands bordering on the 
Pacific Ocean, but in the State of Panama it is found all across the isthmus.
