Field Identification

26–35 cm (1); 156 g (one male ceramensis) (1); wingspan 47–65 cm (1). Several congenerics share Moluccan range: A. henicogrammus is larger and lacks rufous collar, while A. meyerianus is also larger and either black and white or all black, A. griseogularis (N Moluccas) has paler upperparts and rufous underparts (but shares collar), and A. novaehollandiae (S Moluccas) has deep rufous underparts, lacks collar and pallidiceps of Ambon has whitish head (1). Present species is small, slender sparrowhawk with dark slate upperparts, whitish throat with dusky speckling, rufous-pink underparts, mid-length, pointed wings, short, faintly barred tail but long legs and toes (1), which is distinguished by bright rufous collar; underparts unmarked. Female is 13–28% larger and is considered to be slightly darker above and greyer below (1). Bare parts: irides yellow (duller in juvenile) and cere and legs greenish yellow (greener in juvenile) (1). Juvenile has typical brown-streaked cream underparts of genus, blackish-brown upperparts (the feathers with variable rufous fringes, especially on hindneck) and closely barred tail (1). Race ceramensis slightly larger and blacker above, with some pale grey on underparts; juvenile has broader rufous fringes to feathers of upperparts (1).

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Traditionally thought to be closely related to A. cirrocephalus; these two generally considered to form a species-group with A. brachyurus and possibly A. rhodogaster. Two subspecies recognized.

Subspecies


SUBSPECIES

Accipiter erythrauchen erythrauchen Scientific name definitions

Distribution

Morotai, Halmahera, Bacan and Obi (N Moluccas).

SUBSPECIES

Accipiter erythrauchen ceramensis Scientific name definitions

Distribution

Buru, Ambon and Seram (S Moluccas).

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Primary forest in lowlands and hills, from sea-level up to 1450 m (2), but recorded just twice (both times at 150 m) (3) below 650 m on Seram, where suspected to be largely replaced by A. novaehollandiae (4). Also in tree plantations and selectively logged lowland forest.

Movement

Apparently sedentary.

Diet and Foraging

Small birds. Prey captured in typical sparrowhawk fashion, after quick dash from hidden perch in forest or at forest edge. One seen chasing Red Lory (Eos bornea).

Sounds and Vocal Behavior

Undescribed (1).

Breeding

No information available.

Not globally threatened. Currently considered Near Threatened. CITES II. Restricted-range species, endemic to Maluku province, Indonesia. Status very poorly known. Uncommon, but unobtrusive and easily overlooked. Population tentatively estimated, based on extent of available habitat, at up to 10,000 mature individuals BirdLife International (2014) Species factsheet: Accipiter erythrauchen. Downloaded from http://www.birdlife.org on 30/07/2014. . Main threat is habitat loss through commercial logging, forest clearance to create plantations of oil palm, coffee, rubber and timber species, and smaller scale felling for shifting agriculture, mining and settlements (5). General conversion of humid forest to scrub may increase the probability of wildfires, which have affected large areas on other Indonesian islands (5). Analysis of deforestation in the Northern Maluku Endemic Bird Area using remote sensing data revealed that subspecies erythrauchen lost 19% of its forest habitat between 1990 and 2003, and that a total of 34% will have been lost within three generations, if past rates of forest loss continue (5). This study triggered uplisting to Near Threatened in 2014, because the species is highly forest dependent and it is therefore likely that its population will undergo a moderately rapid decline over three generations BirdLife International (2014) Species factsheet: Accipiter erythrauchen.

There is no information deforestation rates in the southern portion of the species range not covered by this study and inhabited by subspecies ceramensis BirdLife International (2014) Species factsheet: Accipiter erythrauchen.
