Bestimmung

This small owlet has a rounded head and is finely barred all over. There is no clear facial disk and the wings are brownish and the tail is narrowly barred in white. There are two subspecies, the nominate form is found in the plains of India and Sri Lanka, while G. r. malabaricum of the Western Ghats is shorter tailed and shows more brown on the head. It has been suggested that the latter may warrant full species status.<p>The plumage on the upper parts is dark black-brown barred with white. The wing coverts have white and rufous patches. The primaries and secondaries are dark brown and barred with pale chestnut. The lower side is whitish or pale rufous barred with black. There is a whitish patch on the chin, upper breast and centre of the abdomen. The iris is yellow, the bill and tarsi are greenish with black claws.<p>In Sri Lanka, the chestnut-backed owlet (Glaucidium castanonotum) was once included as a subspecies but this is elevated to full species. It is found in the wet zone ,whereas G. radiatum is found in drier forests.

Resident species

Verhalten

This owlet is mainly active at dawn and dusk, but is known to call and fly during the daytime as well. The call is distinctive and consists of a rapid series of prao..prao.prao-prao-prao that increases and then fades in volume before ending abruptly. At their daytime roosts, they may be mobbed by drongos, treepies and sunbirds. During the day, young nestlings produce tick calls not unlike that of a pale-billed flowerpecker.<p>The Jungle Owlets roost inside tree cavities and when disturbed they freeze and appear like a dead tree stump. They sometimes perch prominently on wires or bask in the morning sun before retiring to their roost. Also, they have been known to capture small Phylloscopus warblers during the day, although their peak foraging hours are an hour before sunrise and after sunset. Their diet consists of insects, small birds, reptiles, and rodents.<p>The breeding season in India is March to May, and they nest in the hollow of a tree at a height of 3 to 5 m (10 to 16 ft). The typical clutch consists of four eggs (three eggs in G. r. malabaricum).
