Description

The brown wood owl is a medium-sized bird, about 13-17 inches in length, with a wingspan of up to 34 inches. The upper parts are a chestnut brown in color, and heavily-barred in dark brown to blackish. The primary flight feathers are barred chestnut and dark brown; the secondaries and wing-coverts are a reddish-yellow, barred with dark tawny-brown. Chest and belly are a cream color, densely marked in light brown to brown. Like other owls females are slightly larger than males.

The facial disc is reddish-yellow to rufus-brown, ringed with a black rim. The eyes are dark brown, surrounded by additional dark brown feathers that give them a much larger appearance. The gray to blue-gray beak is framed on either side by grayish feathers.

Range and habitat

Brown wood owls are found in southern and southeastern Asia, from India east into Burma, Thailand, Malaysia, and several islands of Indonesia. They inhabit dense tropical forests from the sea coast into lowlands and hilly areas not higher than 1,600 feet.

Habits

Little is known of brown wood owls due to the shy, retiring nature of the birds. When disturbed they compact their feathers to better resemble a stump on a branch. More often they are heard rather than seen, especially on a moonlit night, calling "who-whoowwwwooh" in under a second. Breeding is known only in southern India, when the season is January to March; two eggs are laid.

Threats

Despite being listed as "least concern" by the ICUN[2], the overall population of brown wood owls is suspected of declining, with habitat destruction by man as the cause.
