Circus assimilis
The Spotted Harrier (*Circus assimilis*) is a slim, medium-sized bird of prey found across much of mainland Australia. This raptor is well known for its graceful, low flight as it glides over open grasslands and woodlands in search of food. Its long legs, narrow wings, and unique plumage make it one of the more easily recognised birds of prey in open country.
1. Chestnut underparts with bold white spots (adults); streaked, buff underparts (juveniles)
2. Long legs, narrow wings, and a long, barred tail
3. Owl-like facial disc and low, gliding hunting flight
Spotted Harriers primarily hunt on the wing, using their slow, methodical flight to locate ground-dwelling prey such as small mammals (including rodents and bandicoots), birds (like quail and pipits), reptiles, and occasionally large insects. They are mostly solitary and tend to be quiet, except during the breeding season when they become more vocal. Breeding occurs from August to December, with nests built high in trees using sticks and lined with leaves. Females do most of the nest building and incubation, while males provide food. Clutches usually contain up to four eggs, and the young remain in the nest for several weeks.
Spotted Harriers are found throughout mainland Australia, favouring open habitats such as grasslands, open woodlands, agricultural fields, and lightly wooded plains. They are rarely seen in dense forests or wetlands. Look for them flying low over open areas or perched on fence posts and small trees, especially during dawn and dusk when they are most active.
