Distribution: Indomalayan. NEPAL, INDIA, and SRI LANKA east to southern CHINA (Hainan) and TAIWAN south through Indochina to JAVA. more....

Subspecies: 11 races. A. t. castroi: PHILIPPINES (Polillo Is., off Luzon); A. t. extimus: Southeastern PHILIPPINES; A. t. formosae: TAIWAN; A. t. indicus: North-central, northeastern and eastern INDIA and NEPAL to South CHINA and south to INDOCHINA and MALAY PENINSULA; A. t. javanicus: JAVA and BALI; A. t. layardi: SRI LANKA; A. t. microstictus: BORNEO; A. t. niasensis: Western SUMATRA (Nias Is.); A. t. palawanensis: PHILIPPINES (Palawan, Calamianes); A. t. peninsulae: Southwestern INDIA; A. t. trivirgatus: SUMATRA.

Taxonomy: Forms a superspecies with A. griseiceps.

Movements: Irruptive or local migrant, with juveniles dispersing from breeding areas (Bildstein 2006).

Habitat and Habits: Occurs in broad-leafed and coniferous forest, urban parkland, and marshes. Apparently prefers more mature habitats than the similar Besra (A. virgatus). In the Malay Peninsula, it occasionally occurs in mangroves (Parr 1988), but not peatswamp forest, and is widespread in tall evergreen and semi-evergreen lowland forest, mature and recovering from logging, at plains level and on hill-slopes to about 250 m (Wells 1999). It also occurs in edge habitat, far into plantation agriculture, and in well wooded suburbia (Wells op cit.). Usually solitary, but pairs may soar together. more....

Food and Feeding Behavior: Prey items include squirrels, rodents, bats, and birds (Carey et al. 2001). It still-hunts from perches in the lower canopy or in the mid-stratum of forest, and in dense edge cover, taking prey from trees, from the ground, and occasionally in flight (Wells 1999). In the Philippines, it tends to hunt from a perch low in the forest, but sometimes perches on exposed upper branches (Kennedy et al. 2000).more....

Breeding: Builds a stick nest placed in a fork near the top of a tree. The nest is lined with green leaves and material continues to be added during incubation. Clutch size is 2 eggs, which are white and unmarked. Pairs will re-nest after failed attempts. more....

Conservation: Categorized globally as a species of "Least Concern" by BirdLife International (2007).more....
