Subspecies: Monotypic.

Taxonomy: Placed in the genus Accipiter by Stresemann and Amadon (1979) and Amadon and Bull (1988), who were followed by Coates (1985), but now considered to form part of an older Australasian group. Forms a superspecies with the Red Goshawk, E. radiatus, of Australia. more....

Movements: Probably non-migratory.

Habitat and Habits: Frequents hill and lower mountain forest (Coates 1985, Beehler et al. 1986). Beehler (1978) indicated that it was confined to undisturbed forest in the Wau area. Not known to soar and is probably very secretive, judging from the paucity of records.

Food and Feeding Behavior: According to Beehler et al. (1986), this species preys on birds.

Breeding: No information.

Conservation: Diamond (1972) knew of only eight specimens of this species, and he regarded it as the rarest of the New Guinea hawk species. According to the BirdLife International "Data Zone" site, there have been no records of this species in the last five years. Categorized as "Data Deficient" by BirdLife International.
