|
| Distribution: Indomalayan. Endemic to the NICOBAR ISLANDS (Car Nicobar, Katchall, and possibly other islands). |
|
| Subspecies: 2 races. A. b. butleri: NICOBAR ISLANDS (Car Nicobar); A. b. obsoletus: NICOBAR ISLANDS (Katchall).
|
|
| Taxonomy: Forms a superspecies with A. badius and A. brevipes. Possibly conspecific with A. badius (Brown and Amadon 1968, Amadon and Bull 1988) but see Wattel (1973) and Mees (1981), who noted differences in plumages, morphology, and habitat choice between the two. |
|
| Movements: Non-migratory (Bildstein and Zalles 2005). |
|
| Habitat and Habits: Occurs in forested habitats. |
|
| Food and Feeding Behavior: Feeds chiefly on lizards and insects, according to Ferguson-Lees and Christie (2001). |
|
| Breeding: The only recorded nest, just completed, was ca. 12 m high at the end of a horzzontal branch of a Ficus tree (Ferguson-Lees and Christie 2001). There is no information on clutch size, or incubation and nestling periods. |
|
| Conservation: Butchart et al. (2005) noted that specimens from Great Nicobar and Camora have recently proved to be misidentified examples of the Besra (Accipiter virgatus), throwing into doubt sightings from those islands and other nearby ones. Categorized as Vulnerable by BirdLife International (2008), based on the lack of recent sightings and ongoing habitat destruction on the islands However, there are no population estimates, and the actual status of this species urgently needs to be investigated. |
