THE RAZOR-BILLED CURASSOWS. 215 
her wherever she went about the grounds. I found this kind 
of Curassow bird was very common in the forests of the 
Cupdri; but it is rare on the Upper Amazons. These birds 
in their natural state never descend from the tops of the loftiest 
trees, where they live in small flocks and build their nests. It 
is difficult to find the reason why these superb birds have not 
been reduced to domestication by the Indians, seeing that 
they so readily become tame. The obstacle offered by their 
not breeding in confinement, which is probably owing to their 
arboreal habits, might, perhaps, be overcome by repeated 
experiment ; but for this the Indians probably have not suf- 
ficient patience or intelligence.”
