Taxonomy: This form and its component races have been lumped with A. toussenelii by many authors, including Stresemann and Amadon (1979), Amadon and Bull (1988), and Ferguson-Lees and Christie (2001). However, Kemp and Crowe (1994) found morphological differences between the two groups, and there is possibly a zone of overlap in the Democratic Republic of Congo (a view disputed by Louette 2002). In various papers, Louette (2003, 2007) has argued that these populations comprise a single species, but based on several lines of evidence, Clark and Davies (2000) favored treating the two groups as separate species, and their view is followed here, pending molecular studies.

Movements: Irruptive migrant (Bildstein and Zalles 2005).

Habitat and Habits: A forest hawk, occurring in dense forests and woodlands, especially moister areas, virtually throughout sub-Saharan Africa. Like other African Accipiter species, it exploits plantations of exotic trees. Usually highly secretive and rarely seen away from cover, except when engaging in noisy aerial displays (Dowsett-Lemaire and Dowsett 2006). Occurs singly. more....

Food and Feeding Behavior: Preys on most small vertebrates, including squirrels, rodents, bats, a wide variety of birds, snakes, lizards, chameleons, frogs, and large insects. Typically hunts from a concealed perch, dashing out to chase prey. Reflecting the pronounced reversed sexual size dimorphism in this species, the male probably takes smaller bird species than the female.

Breeding: Breeding has been recorded from September-April in southern Africa, peaking slightly earlier in the southernmost portions of the range (Allan 1997). Egg laying in Zimbabwe (Irwin 1981) and the Transvaal (Tarboton et al. 1987) spanned September-November with an October peak. Builds a small stick nest well hidden in foliage, often among epiphytes. Some nests are re-used, sometimes for many years. Both members of the pair build or refurbish nests. Clutch size is 2-3 eggs, which are white and unmarked. The incubation period is 30 days, and the young fledge about 35 days later. They remain in the vicinity of the nest for two or three months before achieving independence. more....

Conservation: Widespread and common throughout its range. Categorized globally as a species of "Least Concern" by BirdLife International. more....
