Despite being often recorded at carrion, the numerous scavengers in their range, largely vultures, jackals and occasionally hyenas, are larger and often aggressive towards other scavengers. professional advice. The underwing of juvenile has black tips and whitish panel similar to adults but the inside of the wing is rufous-buff (similar to body feathers) streaked with brown. Jackal buzzards have been recorded at various carrion, including many sheep and goat carcasses and placenta, as well as largely road-killed hares, springhares, springboks and steenboks. [5] 18 jackal buzzards were found to have averaged 1,059.4 g (2.336 lb). Mostly it prefers to be close to grassland in which to execute most of its hunting. Both morphs often have plain underparts, lacking the breast band frequently seen in the nominate Common Buzzard (B. b. buteo). The fact that its call is reminiscent of that of black-backed jackal, is believed to be the source of the species' common name. Below the chin and around the throat is mainly chestnut, and the rest of the underparts and the underwing coverts are rich rufous but for a contrasting black abdomen with faint white bars. (2001). Males tend to weigh less and as such are the more efficient hunters and fliers. [4][8] An unlikely confusion species is the slightly larger bateleur, given its short rufous tail but the larger-headed, heavier set eagle bears a very distinct and particular head, wing and body shape and obvious distinct colours as adults. However the aerial display of the pair on territory tends to be much less dramatic than that of the augur buzzard, usually confined to circling or gentle stooping. Simmons, R., K. Retief & van Beuningen, D. (2011). Its tail is also paler than the nominate form and often quite rufous, quite similar to that of the North American Red-tailed Hawk. Ferguson-Lees, J., & Christie, D. A. As in other tropical raptors compared to temperate-zone relatives, the breeding cycle is relatively elongated and clutch size relatively small in the jackal buzzard compared to temperate-zone Buteo species. [4][15] Two creamy or bluish white eggs (or very rarely three) are laid at about three day intervals and incubated by the female only, although food is brought to her on the nest by the male. [4][6], The adult jackal buzzard is strikingly plumaged and arguably one of the most "handsome" buzzards. The Common Buzzards plumage is a rich brown, with lighter markings beneath.
