The White-bellied Guan is very abundant in the Pacific coast region, and in the 
early morning the woods in the neighbourhood of the more remote villages resound with | 
its loud continued cries. It is usually to be seen perched on the trees, and on being 
approached exhibits scarcely any symptoms of alarm. The breeding-season appears to 
extend over a considerable period, as young birds and fresh eggs were observed 
simultaneously in the month of March. The chicks appear to run almost as soon as 
they are hatched, and display great agility in avoiding capture by clinging to the 
branches of the underwood. The nest, composed entirely of twigs, is usually placed 
in a low bush, and contains two creamy-white eggs with rough shells, measuring 1°d 
by 1°25 inch.
