The Northern race of Jungle Owlet is found from the Sub¬-Himalayas, where it occurs up to about 4,000 feet, down as far South as Khandesh in the Bombay Presidency on the West and to the mouths of the Godavery on the East. It occurs in the Nilgiris also, and Macpherson records taking its eggs in Mysore. It is not found in Sind and the Punjab, but is resident in the Arivalli Hills in Rajputana. In the Bombay Deccan and in the Western and Central Provinces it is nowhere common.
This is a Jungle Owlet and keeps to forest or thickly wooded country. Over most of its area it will be seen most often in thin deciduous forest and in orchards, but it often breeds in evergreen forest and has also, on the other hand, been found nesting in gardens. Cockburn, writing from Allababad, says : “a clutch of three eggs of this Owl were taken by me on the 21st March out of a hole in a horseradish-tree in my garden. The bird is common in this, the old side of the Cantonments." Darling says that in Coonoor it breeds “in rather open jungle,” while in the United Provinces Osmaston took eggs from trees standing “in scrub-jungle.”
As a rule the birds select a natural hollow in a tree some 10 to 25 feet from the ground, and more often under than over 15 feet. Occasionally they make use of the deserted nests of Barbets or Woodpeckers.
The breeding season is April and May, sometimes March, while Harrington Bulkly took eggs as early as the 24th February.
The full clutch of eggs is three or four, but Macpherson took a single hard-set egg from a hole occupied by a pair of this species on the 22nd March.
Twenty-eight eggs average 31.5 x 26.8 mm, ; maxima 34.2 x 27.3 and 31.3 x 27.5 mm. ; minima 30.6 x 26.4 and 31.0 x 26.0 mm.
Both birds are often found together in the nesting-hole, but there is nothing on record as to whether the male really incubates.
