Brown boobook
The brown boobook, also known as the brown hawk-owl, is an owl which is a resident breeder in south Asia from India, Sri Lanka, Bhutan, Bangladesh and Nepal east to western Indonesia and south China.
This species is a part of the larger grouping of owls known as typical owls, Strigidae, which contains most species of owl. The other grouping is the barn owls, Tytonidae.
Taxonomy
The brown boobook was formally described in 1822 by Stamford Raffles from a specimen collected in Sumatra under the binomial name Strix scutulata. The specific epithet is from Latin scutulatus meaning "diamond-shaped". The brown boobook is now placed with the other boobooks in the genus Ninox that was introduced by the English naturalist Brian Houghton Hodgson in 1837.Description

The underparts are whitish with reddish-brown streaking, although the subspecies found in the Andaman Islands has dark brown underparts. The eyes are large and yellow.
