Distribution: Indomalayan. Endemic to SULAWESI. more....

Subspecies: Monotypic.

Taxonomy: May belong to the Besra (A. virgatus) superspecies complex (Wattel 1973).

Movements: Non-migratory (Bildstein and Zalles 2005).

Habitat and Habits: Thought to mainly inhabit primary hill and montane forest, but is seldom observed, as it forages mainly in the forest interior and along trails and roads in forests (Coates and Bishop 1997). Martin et al. (2012) recorded this species twice at near sea level on Buton Island, and Catterall (unpublished) also found it near sea level during an atlas survey of that island. Sometimes perches on a high branch exposed to the early morning sun and flies swiftly through the forest (Coates and Bichop op cit.). Observed singly, or occasionally in pairs.

Food and Feeding Behavior: Feeds mainly on large insects (cicadas and grasshoppers) and snails and also takes small birds, which it captures by diving swiftly from a high perch to take prey on or near the ground at the forest edge (Coates and Bishop 1997).

Breeding: No information.

Conservation: Apparently the least common of Sulawesi's three endemic accipiters, but probably overlooked to some extent (Ferguson-Lees and Christie (2001). Categorized globally as "Near Threatened" by BirdLife International, but any decision on the status of this species seems premature because it has received so little ornithological attention. A focused study might show that it is not uncommon.
