These three specimens agree with others in the British 
Museum. They are in somewhat worn plumage and all are 
beginning to moult. 
This Guan seems to prefer the wooded slopes of the 
conical hills, and was usually observed in parties of about half 
a dozen. When alarmed they perched on the tops of the tallest 
trees, but could generally be approached within gunshot. 
The call is loud, but quite different from that of the Ortalis , 
and the flight is fairly swift and gliding. Only noticed from 
the Concurencia northwards.

These specimens are identical with examples in the British 
Museum from Northern Argentina. 
I can add nothing to the excellent description of the 
habits and call of this Guan given by Prof. Graham Kerr in 
f The Ibis ’ for 1892 (p. 148). 
On two occasions I saw the nest, which was placed in the 
topmost branches of a tallish tree and was a fair structure of 
sticks ; according to the natives the eggs are of about the 
size and colour of the egg of the domestic fowl. 
I first observed the bird at Colonia Mihanovitch, N. Argen¬ 
tine, but it was heard or observed commonly right up to 
Corumba, The only native name I heard for it was 
“ Yacu ”
