The tawny fish owl is a fish owl species in the family known as typical owls, Strigidae. It is native from southern Nepal to Bangladesh, Vietnam and China and Bhutan. Due to its wide geographical distribution, it is listed as Least Concern on the IUCN Red List.
Region
Himalayan foothills to southern China and northern Indochina
Typical Environment
This owl inhabits forested rivers, rocky streams, and lakes from southern Nepal and Bhutan through northeastern India and Bangladesh into northern Myanmar, northern Vietnam, and southern to central China. It favors riparian broadleaf and mixed forests with dense cover and quiet pools or riffles. It also uses reservoirs, forest-fringed ponds, and fish farms when cover is nearby. Steep ravines, gorges, and mature riverine gallery forests are typical sites.

The tawny fish owl is a large, riverine owl specialized for catching fish and other aquatic prey. It often hunts from low perches over water, sometimes wading to snatch prey with rough, spicule-covered toes. Its booming duet carries far along valleys, so it’s more often heard than seen. The species is sensitive to disturbance of forested streams and rivers.

Temperament
solitary and territorial
Flight Pattern
strong flier with deep, steady wingbeats; low, direct flights along waterways
Social Behavior
Usually encountered as single birds or territorial pairs along a stretch of river. Pairs maintain long-term territories and often duet at dusk and night. Nests are placed in large tree cavities, cliff niches, or occasionally on old stick platforms; they are early-season breeders in parts of the range.
Migratory Pattern
Resident
Song Description
A resonant, booming series of hoots, often a deep two-note phrase repeated at intervals. Males give lower-pitched notes; pairs may duet antiphonally. Harsh screeches and barks are also given near the nest.
Plumage
Rich tawny to rufous-brown plumage with bold dark streaking on the underparts and barring on wings and tail; loose, shaggy feathering gives a bulky look.
Diet
Primarily fish and freshwater crabs, with frogs and other amphibians taken frequently. It also captures aquatic insects, small reptiles, and opportunistically small mammals and birds near water. Prey is seized by powerful feet with rough, spicule-covered toes that help grip slippery catches.
Preferred Environment
Hunts from low branches or rocks overhanging quiet pools, riffles, and stream edges. It may patrol along riverbanks and occasionally wade in shallow water. Artificial water bodies like reservoirs and fish farms are used where adjacent forest cover provides concealment.
