Dark Chanting Goshawk

The Gabar Goshawk, a bird of prey from the Accipitridae family, presents a fascinating case of polymorphism. This species exhibits two distinct color morphs: the more common pale form, with its predominantly grey upperparts, white rump, and barred chest, thighs, and underwings, and the rarer, almost entirely black form. Both adult morphs share dark eyes, long legs, and a red cere, while juveniles display a yellow cere and legs, and a generally browner plumage with less defined barring. Females are notably larger than males, with body lengths ranging from 28 to 36 cm and a wingspan of approximately 63 cm.

Identification Tips

To identify the Gabar Goshawk, look for the striking white rump and the barred tail in the pale morph. The dark morph can be recognized by its near-black appearance. Juveniles can be distinguished by their yellow cere and legs, as well as their untidier barring compared to adults.

Habitat

The Gabar Goshawk is found in open woodlands, particularly favoring dry Acacia savanna and broad-leaved woodlands. It can also be seen in tree-lined watercourses in arid regions and occasionally in urban areas.

Distribution

This species is widespread across sub-Saharan Africa and extends into the Arabian Peninsula. It is divided into three subspecies: M. g. aequatorius in the highlands from Ethiopia to northern Mozambique, M. g. gabar from southern Angola to South Africa, and M. g. niger from Senegambia to Sudan and southwestern Arabia.

Behaviour

Typically sedentary, the Gabar Goshawk may exhibit nomadic tendencies in immature birds and some migratory movements. It is often seen alone or in pairs during the breeding season, engaging in aerial pursuits or calling from perches.

Breeding

Nesting occurs in thorny trees, where the goshawk uses spider webs, including live spiders, to construct its nest, possibly aiding in camouflage and parasite control. Breeding season peaks from September to November, with clutches of two eggs being common. The female primarily incubates the eggs for about 33–38 days, and chicks fledge around 35–36 days old.

Diet and Feeding

The Gabar Goshawk primarily preys on small birds, but will also hunt small mammals, reptiles, and insects. It employs an energetic pursuit to flush out prey from trees or may hunt from a perch, swooping down to capture its target.

Conservation status

The Gabar Goshawk is currently listed as Least Concern on the IUCN Red List, indicating a stable population without significant immediate threats to its survival.
