|
| Distribution: Indomalayan. Endemic to SULAWESI and the islands of Talisei, Mona, and Butung. more.... |
|
| Subspecies: Monotypic. more.... |
|
| Taxonomy: Wattel (1973) could not determine any close relatives of this species, but its relationships might be revealed with molecular techniques. |
|
| Movements: Non-migratory (Bildstein and Zalles 2005). |
|
| Habitat and Habits: Inhabits primary hill and lower montane forest, tall secondary forest and mangroves, typically perching in the forest understory, close to a tree trunk (Coates and Bishop 1997). Often quite active, rarely perching for long at one site, and not known to soar. Occurs singly, or occasionally in pairs (Coates and Bishop op cit.). |
|
| Food and Feeding Behavior: Preys mainly on lizard and snakes, and also eats bats, birds, frogs, grasshoppers, and snails (Coates and Bishop 1997. |
|
| Breeding: No information. |
|
| Conservation: According to Ferguson-Lees and Christie (2001), this is the most numerous of the four species of accipiters endemic to Sulawesi, and they suggested that it is still "moderately common". Categorized globally as a species of "Least Concern" by BirdLife International (2008). |
|
| Population Estimates: There are no available data on the population size of this species, but Ferguson-Lees and Christie (2001) suggested that it might have a five-figure population, based on the extent of forest remaining in Sulawesi. |
