 parts. It is said to build in trees. The Spanish name is ' Pavo' 

 which is translated as ' Turkey ' by some, and ' Peacock ' by 

 other writers on Central America.

This Guan is very abundant in the Pacific coast-region, where, 

 in the neighbourhood of the more remote and smaller villages, the 

 woods in the early morning resound with its loud continued 

 cries. Like Penelope purpurascens, it is usually seen in trees, 

 and shows little symptom of alarm on one approaching. The 

 time of breeding seems to extend over some period, as young 

 birds and fresh eggs were observed simultaneously in the month 

 of March. The former appear to run almost immediately on 

 becoming free from the shell, and, clinging to the branches of the 

 underwood, are nimble in eluding capture. The nest is usually 

 placed in a low bush, and is composed entirely of small twigs. 

 The eggs, two in number, are of rough texture, and in colour 

 pure creamy-white j they measure, axis 1'25 in,, diam. 1*5 in.

This bird, one of the most curious as well as the most in-
