Members of the genus Bubo are the largest of the owls. Heavily built with powerful talons they are recognisable by their size, their prominent ear-tufts, and their eyes that vary in colour from yellow to brown but are frequently vivid orange. The genus, including the Asian fish owls of the genus Ketupa – now believed to be part of Bubo – comprises of 20 species ranging Eurasia, Indonesia, Africa and the Americas. DNA evidence suggests that the Snowy Owls of Nyctea and the fish owls of Scotopelia are also candidates for inclusion in this genus.
Above brown narrowly tipped and banded across with tawny buff over the whole of the upper surface, these bars less distinct on the crown, but broader and deeper colored on the hind neck. Outermost scapulars tipped and spotted with yellowish buff on the outer web, forming a distinct shoulder patch. Primary coverts nearly uniform dark brown, with faint indications of lighter brown bars. Quills dark brown, barred darker; tail dark brown, broadly tipped with whitish and crossed with six other bands of fulvous ; face dusky brown with whitish shaft streaks; feathers above the eye blackish. Ear tufts 9 cm long, dark brown, notched and barred with fulvous or white on the inner web. Cheeks with white stiff feathers mesially streaked with brown ; chin whitish-rest of under surface of body white, washed here and there with fulvous and barred across with dark brown ; under tail coverts the same, also the under wing coverts.

Subtropical/tropical lowland and montane moist forest from 300m up to 3000m
Nest built in cavity or emtpy raptor nest. Also on bare soil. Clutch size 1 egg which is, like the nestlings, is defended fiercly.

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
