The black coucal (Centropus grillii) is a species of cuckoo in the family Cuculidae. It has a wide distribution in Africa south of the Sahara.
The male black coucal is 30 cm (12 in) in length while the female is 34 cm (13 in), otherwise they are similar in appearance. [2] In breeding plumage the head, body and tail are black, apart from some buff barring on the rump, and the wings are rufous. Outside the breeding season, the upper parts are dark brown with rufous barring. The eyes are brown and the beak and legs are black. Juveniles are rufous with various dark and light barring and streaking. [3]
It is found in Angola, Benin, Botswana, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Republic of the Congo, DRC, Ivory Coast, Ethiopia, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Malawi, Mali, Mozambique, Namibia, Niger, Nigeria, Rwanda, Senegal, Sierra Leone, South Africa, Sudan, Swaziland, Tanzania, Togo, Uganda, Zambia, and Zimbabwe. [1] It is resident in some locations and migrant in others. Its habitat is marshes, savannah, grassland, bracken, undergrowth, and clearings in woodland, and occasionally reeds and papyrus. It usually occurs below 1,500 m (5,000 ft) but occasionally up to 2,000 m (6,600 ft). [2]
The species has the role of sexes reversed with the males tending the nest while females are polyandrous and maintain territories. Studies on the hormonal system show that progesterone is responsible for controlling the aggressiveness of females. [4]
The black coucal is a generally uncommon bird with a very wide range. No particular threats have been identified and the population is believed to be steady, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern". [1]
Cuckoos are birds in the Cuculidae family, the sole taxon in the order Cuculiformes. The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae respectively. The cuckoo order Cuculiformes is one of three that make up the Otidimorphae, the other two being the turacos and the bustards.
The greater coucal or crow pheasant, is a large non-parasitic member of the cuckoo order of birds, the Cuculiformes. A widespread resident in the Indian Subcontinent and Southeast Asia, it is divided into several subspecies, some being treated as full species. They are large, crow-like with a long tail and coppery brown wings and found in a wide range of habitats from jungle to cultivation and urban gardens. They are weak fliers, and are often seen clambering about in vegetation or walking on the ground as they forage for insects, eggs and nestlings of other birds. They have a familiar deep resonant call which is associated with omens in many parts of its range.
The green-billed coucal is a member of the cuckoos. It is endemic to Sri Lanka's wet zone and listed as Vulnerable on the IUCN Red List, as the small population declined due to forest destruction and fragmentation. It inhabits the tall rainforests of southwest Sri Lanka and nests in bushes. Its typical clutch is 2–3 eggs.
The Senegal coucal is a member of the cuckoo order of birds, the Cuculiformes, which also includes the roadrunners, the anis, and the hoatzin. It is a medium-sized member of its genus and is found in lightly-wooded country and savannah in central and southern Africa.
A coucal is one of about 30 species of birds in the cuckoo family. All of them belong in the subfamily Centropodinae and the genus Centropus. Unlike many Old World cuckoos, coucals are not brood parasites, though they do have their own reproductive peculiarity: all members of the genus are sex-role reversed, so that the smaller male provides most of the parental care. At least one coucal species, the black coucal, is polyandrous. Some species have the male investing more in incubation and parental care. DNA evidence has indicated that they should be raised to family status, as Centropodidae.
The Andaman coucal or brown coucal is a species of non-parasitic cuckoo found in the Andamans, Coco and Table Islands. It is sometimes treated as a subspecies of the greater coucal. It is found mainly in forested habitats and thickly covered gardens.
The Gabon coucal is a species of cuckoo in the family Cuculidae. It is mainly found in Gabon but also occurs in neighboring areas of Cameroon, Angola, the Central African Republic, the western Congo Basin and Equatorial Guinea.
The lesser coucal is a species of cuckoo in the family Cuculidae. It has a wide distribution range that overlaps with several other similar species. The habitat in which it is found is often marshy land with grass and tree cover. It is distinguished by its smaller size, less prominent bill, pale shaft streaks on the feathers of the head and back. It has a much longer claw on its hind toe and a distinct call. It is also among the few coucals that show season plumage differences but like in other coucals, the sexes cannot be distinguished in the field.
The coppery-tailed coucal is a species of cuckoo in the family Cuculidae. It is found in Angola, Botswana, the Democratic Republic of the Congo, Malawi, Namibia, Tanzania, Zambia, and Zimbabwe. It was first described by the German ornithologist Anton Reichenow in 1896.
The black-throated coucal is a species of cuckoo in the family Cuculidae. It is found in West Africa in dense second growth along forest edge and grassy swamps. The subspecies found in northern and central Zaire is sometimes split as Neumann's coucal.
The buff-headed coucal is a species of coucal. These are often placed in the cuckoo family (Cuculidae) but seem to warrant recognition as a distinct family. C. milo is a common endemic of the central islands of the Solomon Islands. Its natural habitat is tropical moist lowland and mountain forests, mostly in primary and secondary growth.
The blue-headed coucal is a species of cuckoo in the family Cuculidae. It is native to tropical central Africa where its typical habitat is swamps, river banks, forest edges and generally wet locations. It is a common bird with a wide range, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The pheasant coucal is a species of cuckoo in the family Cuculidae. It is found in Australia, Timor and New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests. It has adapted well to canefields in northern Australia. The pheasant coucal is unusual among Australian cuckoos in that it incubates and raises its own young instead of laying its eggs in the nest of another species.
The black-hooded coucal is a species of cuckoo in the family Cuculidae. It is endemic to Mindoro in the Philippines and is one of the most endangered birds in the country. It is threatened by habitat loss and trapping.
The white-browed coucal or lark-heeled cuckoo, 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. Burchell's coucal is sometimes considered a subspecies.
The Malagasy coucal or Madagascar coucal is a species of cuckoo in the family Cuculidae. It is found in Madagascar and in the Seychelles, where it occurs on Aldabra and was formerly present on Assumption Island and Cosmoledo. Its natural habitats are dense vegetation in subtropical or tropical moist lowland forests, mangrove forests, rough grassland, marshes and reedbeds.
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 red-chested cuckoo is a species of cuckoo in the family Cuculidae. It is a medium-sized bird found in Africa south of the Sahara. In Afrikaans, it is known as "Piet-my-vrou", after its call.
The African pied wagtail, or African wagtail, is a species of bird in the family Motacillidae.
The Oriental cuckoo or Horsfields cuckoo is a bird belonging to the genus Cuculus in the cuckoo family Cuculidae. It was formerly classified as a subspecies of the Himalayan cuckoo, with the name 'Oriental cuckoo' used for the combined species. Differences in voice and size suggest that it should be treated as a separate species. The binomial name Cuculus horsfieldi has often been used instead of Cuculus optatus, but is now usually considered to be a junior synonym.
