Distribution: Indomalayan. SULAWESI (Muna and Banggai Island). more....

Subspecies: Monotypic.

Taxonomy: The genus Pernis is a primitive accipitrid with no close relations to Buteo (Seibold and Helbig 1995). Wink (1995) found that it clusters with the Neophron/Gypaetus clade of Old World vultures. Based on molecular sequences of the cytochrome b gene, Gamauf and Haring (2004) found that the cuckoo hawks, Aviceda, form a sister group to Pernis, but their analysis indicated that Henicopernis and the Old World vultures, Gypaetus< and Neophron appear only distantly related to Pernis. These authors also recommended separating the Philippine honey-buzzard populations formerly included as a part of P. celebensis as a full species. Their molecular findings coincide with obvious morphological differences, e.g., the Philippine birds are pale and crested, while the Sulawesi populations of P. celebensis are colorful and lack a crest. more....

Movements: Non-migratory, but juveniles disperse from breeding areas (Bildstein 2006).

Habitat and Habits: Inhabits forest, forest edge, and partly cleared areas. Regularly soars above forest and partly cleared ridges and valleys in midday, but otherwise inconspicuous and easily overlooked. Occasonally perches on exposed bare limbs at the forest edge, or in the forest understorey, but mostly perches among dense foliage in a tall of medium-sized tree. Usually seen singly or in twos, occasionally in small groups (Coates and Bishop 1997).

Food and Feeding Behavior: Food includes bees, bee larvae, honeycomb, and occasionally birds (Coates and Bishop 1997).

Conservation: Classified globally as a species of "Least Concern" by BirdLife International. However, Gamauf and Preleuthner (1998) recommended Vulnerable status, based on a population size of less than 10,000 individuals and apparent population declines.
