- Circus assimilis
White-spotted chestnut breast, blue-grey upper parts, owl-like chestnut coloured facial disc with a narrow light grey ruff, yellow eyes, long slender yellow legs and a long tail, with a wedge-shaped tip. Its long, broad wings have dark, well rounded, 'fingered' tips. The female is larger than the male.
Plains and scrubland, sometimes swamps, open wooded country, particularly in arid and semi-arid areas.
It hunts by day, and the diet includes ground birds such as quail and pipits, also mice, rats, rabbits and lizards. 
Its nest is built in trees in woodland and is a large flimsy platform of twigs and sticks, lined with green leaves. The female incubates the eggs, broods and guards the young. The male hunts and brings food to the female.
