- Spizaetus tyrannus
In flight, the impression is dominated by the strong barring on wings and tail. The flight feathers near the body are shorter than those further out on the wing, making the jizz somethat butterfly-like.
Two subspecies are recognized:
- S. t. serus:
- S. t. tyrannus:
Disturbed secondary humid forest at ca. 622 m (2,042 ft) elevation.
Mostly seen when soaring, often high above the canopy; sometimes gives its characteristic call when soaring.
Hunts from perches, from which it catches mammals and birds.
