About the size of the Collared Scops Owl. Sexes alike. This little owl is very like the last species in shape, size, and general apperance but it is chestnut on back, scapulars, and wing-coverts, and has white underparts marked with blackish shaft-streaks, and bars on the flanks. Some specimens have white spots on the outer scapulars. Irides bright yellow; feet pale yellow.
 

It is shy and wary, and as it frequents the tops of tall trees, usually on steep hillsides, it is seldom seen. It is very diurnal in habits, often hunting and calling in broad daylight. The Mukalan Bassa feeds mainly on insects, such as beetles, but also captures mice, small lizards, and small birds, on occasion; most likely, the larger vertebrate forms of prey are taken only when young are being fed.

The breeding season is from March to May, the eggs being laid on the bare wood in a hole in the trunk or limb of a tree. The two glossy white eggs measure about 35 × 28.2 mm.
