To hunt their prey, individuals of Common Black Hawk perched on low trees, and sometimes can be seen running into the ground chasing crabs.

The flight of Common Black Hawk is deep, loud and slow. When gliding it put wings flat and extends the tail. During the migration may fly with the birds of same species or in mixed flocks, occasionally following the thermals.

Buteogallus anthracinus remain solitary or in pairs, and although there are obvious when perching, it is more commonly found gliding.
