The African cuckoo-hawk, or African baza, (Aviceda cuculoides) is a medium-sized raptor in the family Accipitridae so named because it resembles the common cuckoo. It is found in sub-Saharan Africa and along the eastern parts of Southern Africa, preferring dense woodland and forest of either indigenous or exotic trees.
The male is blackish-brown above with a grey mantle and chest with a blackish crest, the underparts are white marked with broad chestnut bars. The tail is black with three grey bars and grey and white tip. The females are browner with paler chestnut bars on the underparts. Distinctive in flight as a small raptor with a small head with broad, narrowly rounded wings and a medium length tail. Wingspan is just over double the body length, females are slightly larger than males. [3]
The African cuckoo-hawk is found across much of sub-Saharan Africa, [4] and the following subspecies are recognised: [5]
The African cuckoo-hawk is a shy species which occurs in the interior and edges of evergreen forest and deciduous woodlands, including suburban gardens and more open savannas, up to 3,000 m (9,800 ft). When migrating through east Africa it also occurs in drier woodland and bush. [1]
The African cuckoo-hawk is largely sedentary but during April–November some migrate northwards to East Africa, in particular to coastal Kenya, and outside the breeding season some migrate to southern Africa, especially to the Transvaal Highveld. The breeding season varies by geography; in southern Africa breeding happens during September to March; in west Africa the season is June to August; while in Kenya there are two breeding periods per year, the first in March to June and the second from November to February, timed to follow the two rainy seasons. The African cuckoo-hawk's general behaviour is little known, as this species occurs at low densities and has secretive habits, although they are slightly more conspicuous during migration and so may appear more numerous. [1]
The African cuckoo-hawk mainly eats reptiles and insects. It hunts within the canopy by flying from tree to tree, searching from a perch before flying to pluck the prey item from the canopy or ground. The following food items have been recorded in its diet: flap-necked chameleon Chamaeleo dilepsis, southern dwarf chameleon Brachypodion ventrale, lizards, snakes, frogs, fish, fruit bats, mice, birds, grasshoppers and locusts, stick insects, silverfish larvae, caterpillars, mantids and freshwater crabs. [4]
The African cuckoo-hawk is a monogamous, solitary nester, belying its secretive reputation by performing spectacular aerial displays as the breeding season approaches. The nest is constructed by both sexes in 11 days and consists of an untidy platform of twigs, vines and leaves which is lined with leaves, grass and small sticks. It is normally placed in the highest branches of a tree, usually between 10 and 30 metres (33 and 98 ft) above the ground. Normally only one or two eggs are laid, occasionally three. The chicks are fed and brooded by both parents, before they leave the nest after 28 days and take their first flight a few days after that. The juveniles remain dependent on their parents for about a week after their first flight. Wahlberg's eagle Hieraaetus wahlbergi has been recorded preying on the chicks of the African cuckoo-hawk. [4]
The sharp-shinned hawk is a small hawk, with males being the smallest hawks in the United States and Canada, but with the species averaging larger than some Neotropical species, such as the tiny hawk. The taxonomy is far from resolved, with some authorities considering the southern taxa to represent three separate species: white-breasted hawk, plain-breasted hawk, and rufous-thighed hawk. The American Ornithological Society keeps all four variations conspecific.
The raptor subfamily Perninae includes a number of medium-sized broad-winged species. These are birds of warmer climates, although the Pernis species have a more extensive range.
The African hawk-eagle is a large bird of prey. Like all eagles, it belongs to the family Accipitridae. This species’ feathered legs mark it as a member of the Aquilinae subfamily. The African hawk-eagle breeds in tropical Sub-Saharan Africa. It is a bird of assorted woodland, including both savanna and hilly areas but the tend to occur in woodland that is typically dry. The species tends to be rare in areas where their preferred habitat type is absent. This species builds a stick nest of around 1 m (3.3 ft) across in a large tree. The clutch is generally one or two eggs. The African hawk-eagle is powerfully built and hunts small to medium sized mammals and birds predominantly, occasionally taking reptiles and other prey as well. The call is a shrill kluu-kluu-kluu. The African hawk-eagle is considered a fairly stable species and a species of Least Concern per the IUCN.
The lizard buzzard or lizard hawk, is a bird of prey in the family Accipitridae. It is native to Sub-Saharan Africa. Despite its name, it may be more closely related to the Accipiter hawks than the Buteo buzzards.
The African harrier-hawk, harrier hawk or gymnogene is a bird of prey. It is about 60–66 centimetres (24–26 in) in length. It breeds in most of Africa south of the Sahara. The only other member of the genus is the allopatric Madagascar harrier-hawk.
The African paradise flycatcher is a medium-sized passerine bird. The two central tail feathers of the male are extended into streamers that commonly are more than twice as long as the body. The female tail feathers are of moderate length and without streamers. The upper parts of the male body, wings, and tail are boldly coloured in chestnut or rusty shades, but the underparts and the head are variably grey to blue-gray, with the head of the mature male being darker, commonly glossy black with greenish highlights. The beak and other bare areas, including a wattle ring round the eye, match the colour of the surrounding feathers. The female coloration is similar, though not so showy and glossy and with the head paler.
The village weaver , also known as the spotted-backed weaver or black-headed weaver, is a species of bird in the family Ploceidae found in much of sub-Saharan Africa. It has also been introduced to Portugal as well as to the islands of Hispaniola, Martinique, Puerto Rico, Mauritius and Réunion.
The Levant sparrowhawk is a small bird of prey. It measures 32–38 cm (13–15 in) in length with a wingspan of 65–75 cm (26–30 in). The female is larger than the male, but the difference is not as marked as with Eurasian sparrowhawk. The adult male is blue-grey above, with dark wingtips, and barred reddish below.
The Pacific baza, also known as the crested hawk, crested baza, and Pacific cuckoo-falcon, is a slender, medium-sized species of hawk in the family Accipitridae. It is mostly grey, brown, and white coloured and grows to a length of 35–46 centimetres (14–18 in). It is an omnivore and usually does not migrate. The breeding season for the species lasts from September to at least February, during which time specimens commonly fly and vocalise for display. It lives in Australia, Indonesia, Papua New Guinea, Solomon Islands, and East Timor, in forests, savannas, and freshwater bodies. The International Union for Conservation of Nature lists it as a least concern species.
The augur buzzard is a fairly large African bird of prey. This species is distinct in typical adult plumage for its blackish back, whitish underside and orange-red tail, however a dark morph is known while juvenile augur buzzards are generally rather brown in colour. This member of the Buteo genus is distributed in several parts of the central and southern Africa, normally being found from Ethiopia to southern Angola and central Namibia. It is resident and non-migratory throughout its range. This is a species of mountains, and adjacent savannah and grassland. This is a typical buteonine raptor, being a generalist predator which tends to prefer small mammals supplemented by reptiles and birds among various prey items.
The Cape wagtail, also known as Wells's wagtail, is a small insectivorous bird which is widespread in southern Africa. It frequents water's edge, lawns and gardens. It is a mostly resident, territorial species, but has been known to undertake limited altitudinal migration or form flocks outside of the breeding season. Like other wagtails they are passerine birds of the family Motacillidae, which also includes the pipits and longclaws.
The red-thighed sparrowhawk, alternatively known as the red-legged sparrowhawk or the western little sparrowhawk is a species of sparrowhawk in the family Accipitridae from western and northern central Africa.
The Madagascar cuckoo-hawk, also known as the Madagascar baza or the Madagascan cuckoo falcon, is a species of bird of prey in the family Accipitridae. It is endemic to Madagascar.
Ayres's hawk-eagle, also referred to as Ayres' eagle, is a medium-sized bird of prey in the family Accipitridae. It is native to African woodlands. Its name honors South African ornithologist Thomas Ayres.
The African cuckoo is a species of cuckoo in the family Cuculidae. It is found in Sub-Saharan Africa where it migrates within the continent, generally arriving and breeding in any one locality during the rainy season. A fairly common bird, the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The brown-hooded kingfisher is a species of bird in the subfamily Halcyoninae, the tree kingfishers. It has a brown head and blackish and turquoise wings. It is found in Sub-Saharan Africa, living in woodland, scrubland, forest edges, and also suburban areas. The International Union for Conservation of Nature (IUCN) has assessed it as being of least concern.
The grey cuckooshrike is a species of bird in the cuckooshrike family Campephagidae. It is a medium-sized forest bird, with grey to blue-grey plumage and large black eyes. There are two subspecies that occur in forest patches of southern and central Africa respectively.
The black-backed puffback is a species of passerine bird in the family Malaconotidae. They are common to fairly common sedentary bushshrikes in various wooded habitats in Africa south of the equator. They restlessly move about singly, in pairs or family groups, and generally frequent tree canopies. Like others of its genus, the males puff out the loose rump and lower back feathers in display, to assume a remarkable ball-like appearance. They draw attention to themselves by their varied repertoire of whistling, clicking and rasping sounds. Their specific name cubla, originated with Francois Levaillant, who derived it from a native southern African name, where the "c" is an onomatopoeic click sound. None of the other five puffback species occur in southern Africa.
The grey-headed bushshrike, colloquially known as the ghostbird, is a species of passerine bird in the family Malaconotidae. It is widespread throughout sub-Saharan Africa, although relatively absent in Central Africa and the interior of southern Africa. It is the most widespread species of its genus, which consists of large bushshrikes with massive bills and mournful hooting calls. It occurs sparsely in a range of wooded habitats, though typically in denser vegetation within dry or moist savannah. The monogamous pairs occupy woodland with sufficient cover. They are sedentary, but will undertake limited post-breeding movements.
Burchell's coucal, is a species of cuckoo in the family Cuculidae. It is found in sub-Saharan Africa. It inhabits areas with thick cover afforded by rank undergrowth and scrub, including in suitable coastal regions. Common names include gewone vleiloerie in Afrikaans and umGugwane in Zulu. It is sometimes considered a subspecies of the white-browed coucal. It is named after the British naturalist William John Burchell.
