The Bengal eagle owl is also known as the Rock eagle owl, it is a species of large horned owl found in South Asia. Until very recently they were considered to be a subspecies of the Eurasian Eagle Owl.

The male has a deep, resonant, double hoot bu-whooh, which he will repeat at intervals of several seconds. The female's song is similar, with a slightly higher pitch. At the nest both sexes may make a clucking noise, or a series of huwoo-huwoo sounds - again, the female is slightly higher in pitch.

Generally, these Owls will breed from February to April, but this may vary locally between October and May. The nest is usually a shallow scrape on bare earth. This may be on a protected rock ledge, river bank, or a recess in a cliff that is in a ravine. They have also been known to nest on the ground under a bush, or between rocks on a slope.

2-4 white eggs are laid which are incubated by the female for 35 days. Chicks are born with white fluff which is gradually replaced by speckled feathers during the prejuvenile moult after about two weeks. A month or so later they go through a prebasic moult and a brownish juvenile plumage is assumed similar to the adults but the underside is downy. The full adult plumage is assumed much later. In the nest young birds produce clicks, hisses and open up their wings to appear larger than they are to warn off predators.
