This brown-plumaged, short-winged, and exceedingly vociferous Hawk is

common in the woods along the shores of the Plata and its tributaries,

and is never found far removed from water. It perches on the summit of a

tree, and sits there motionless for hours at a time, and at intervals

utters singularly long loud cries, which become more frequent and

piercing when the bird is disturbed, as by the approach of a person.

Its flight is rapid and irregular, the short blunt wings beating

unceasingly, while the bird pours out a succession of loud vehement

broken screams.

Mr. Barrows observed it on the Lower Uruguay, and writes:--"It feeds

largely if not exclusively on fish, nearly every specimen having

their remains (and nothing else) in their stomachs." It would be very

interesting to learn how it captures its prey.
