The nominate subspecies B. c. coromandus is distributed in Pakistan, north and central India, Nepal, Bangladesh, northeast India and east China. The subspecies B. c. klossi is distributed in southern Myanmar and southern Thailand.

The Important Bird and Biodiversity Areas (IBA) of the dusky eagle-owl in Nepal are, Bardia National Park, Chitwan National Park, Sukla Phanta Wildlife Reserve and Koshi Tappu Wildlife Reserve and Koshi Barrage.

Ecosystem and habitat

These owl species have medium forest dependency. These species occur in altitudes from 0 to 250 meters.

They inhabit artificial ecosystems like plantations, dense rural gardens and groves with densely foliaged trees. The natural ecosystem of these species includes tropical and subtropical moist lowland forests, dense woodlands, rivers, streams and creeks.

Diet and feeding behavior

The diet of these owl species is mostly birds. Crows, bee-eaters, parakeets, rollers, coucals, pigeons and doves are their primary food.

Reproduction and breeding habits

The breeding season of the dusky eagle-owl is from November to April in India, with a peak in December and January. These species usually lay eggs in the abandoned stick nests of kites, raptors and other birds of prey.

Migration and movement patterns

The dusky eagle-owl species are non-migratory resident birds.

Post breeding, the juveniles may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.
