The observations of naturalists attached to the late expeditions demonstrate this bird to be 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.
