VOICE: SOUNDS BY XENO-CANTO
Dark Chanting Goshawk often calls from a perch or in flight, uttering an accelerating series of piping notes and fluty whistles, almost a song “kleeu-kleeu-klu-klu-klu”. It also gives a high-pitched “kleee-u”. It is very vocal during breeding season.
HABITAT:
Dark Chanting Goshawk lives in savannahs and open woodlands, favouring broad-leafed woodlands, and mixed bushveld.
RANGE:
Dark Chanting Goshawk lives in sub-Saharan Africa, south western Morocco and south western Arabia. Its range may overlap narrowly with that of Southern Pale Chanting Goshawk.
BEHAVIOUR:
Dark Chanting Goshawk hunts from top of bushes, trees or termite-hills, or other poles. When prey is selected, it dives to the ground and catches lizards, snakes, small mammals or birds, and insects. It may chase birds while flying, but it usually hunts on the ground, after its steep, fast dive from its perch. It is an agile raptor.
Dark Chanting Goshawk is usually seen singly or in pairs, often perched for long periods on a prominent perch, such as tree top or utility poles.
During breeding season, Dark Chanting Goshawk performs flight displays, accompanied with melodious whistles from a tree top or in flight.
FLIGHT:
Dark Chanting Goshawk flies with steady, shallow wing beats. It soars with raised wings.
REPRODUCTION:
Dark Chanting Goshawk’s nest is built on an inside main fork of a woodland tree, usually a thorny Acacia. Small nest is made with sticks and soft grass materials.
Female lays one or two eggs, from August to November (February to March in Morocco). Incubation lasts about 36 days, by female. Young fledge at about 50 days of age.
DIET:
Dark Chanting Goshawk feeds mainly on reptiles, small snakes, lizards, chameleons. It also hunts birds as small pigeon, insects and small rodents.
PROTECTION / THREATS / STATUS:
Dark Chanting Goshawk Morocco’s population is endangered. This isolated population is probably sedentary.
This species is a scarce resident in its range, relatively uncommon.
