The observations of naturalists attached to the late expeditions demonstrate this bird to he of 
common occurrence in Texas, on the Rio Grande. It is a dull and heavy bird in its habits, 
and subsists for the greater part on dead animals. 
This bird appears to belong to the genus Craxirex , as given by Mr. Gould, if not identical 
with his species.
