The montane nightjar (Caprimulgus poliocephalus), mountain nightjar or Abyssinian nightjar, is a species of nightjar in the family Caprimulgidae. It is native to upland regions of Central and Eastern Africa where it is a locally common species.
The Montane nightjar was originally described by the German naturalist Eduard Rüppell in 1840. He used the current binomial name Caprimulgus poliocephalus. [2] [3]
There are four subspecies: [4]
The subspecies C. p. ruwenzorii was formerly sometimes treated as a separate species, the Ruwenzori nightjar. Although a molecular genetic study of these four nightjars has not been published, the results of the detailed measurement of museum specimens suggests that they should be considered as conspecific. [5]
The montane nightjar is a rather dark nightjar growing to a length of about 23 cm (9.1 in). It has somewhat tawny, blackish or chocolate brown dappled plumage. The male has white spots on its four main primaries and the outer edge of the tail is white. The female has buff-coloured spots on its primaries and less white on the tail. The call is a nasal ank-ank-ank, often followed by a high-pitched whistle piiiyu-pirrr, the first syllable descending and then rising, and the second syllable tremulous and descending. [6]
The montane nightjar is native to Central and Eastern Africa. Its range includes Angola, Democratic Republic of the Congo, Eritrea, Ethiopia, Kenya, Malawi, Saudi Arabia, Sudan, Tanzania, Uganda and Zambia. It occurs at altitudes between about 1,000 and 3,350 m (3,300 and 11,000 ft). [1] Like other nightjars, it is nocturnal, feeding on moths and other large insects. It is mostly a forest bird, but is also found in plantations, cultivated areas near forests, and in well-wooded urban areas. [6]
The montane nightjar is a common species with a very wide range. No special threats have been identified and the population trend is thought to be stable. For these reasons, the International Union for Conservation of Nature has rated its conservation status as being of "least concern". [1]
The African thrush or West African thrush is a passerine bird in the thrush family Turdidae. It is common in well-wooded areas over much of the western part of sub-Saharan Africa, it was once considered to be conspecific with the olive thrush but that species has now been split further. Populations are resident (non-migratory).
Meyer's parrot, also known as the brown parrot, is a species of parrot native to Africa. A Meyer's parrot has black feathers, turquoise belly, blue rump, and bright yellow markings on the carpal joint of the wings. Most subspecies have some yellow on the top of the head as well. Forshaw (1989) recognizes six subspecies of P. meyeri which vary in home range, size and in markings, including the extent of yellow markings to the head and wings, and the intensity of turquoise markings on the belly and rump.
The green-winged pytilia is a small colourful seed-eating bird in the family Estrildidae. It is widespread throughout Sub-Saharan Africa, though it is more rarely seen in central, far southern and coastal western parts of the continent.
The grey-headed kingfisher is a species of kingfisher that has a wide distribution from the Cape Verde Islands off the north-west coast of Africa to Mauritania, Senegal and Gambia, east to Ethiopia, Somalia and southern Arabia and south to South Africa.
The scaly spurfowl is a species of bird in the family Phasianidae. It is found in Angola, Burundi, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Ethiopia, Gabon, Kenya, Malawi, Nigeria, Rwanda, São Tomé and Príncipe, Sudan, Tanzania, and Uganda.
The square-tailed nightjar is a species of nightjar in the family Caprimulgidae which is native to tropical and subtropical woodlands of the Afrotropics. It has an extensive range south of the African equator. Despite not having a completely "square tail", its naming highlights a distinguishing field mark. The similarly plumaged slender-tailed nightjar, found in dry bush country of the tropics, differs namely by its protruding central tail feathers. It is alternatively known as the Gabon nightjar or Mozambique nightjar.
The plain nightjar is a species of nightjar in the family Caprimulgidae. It breeds in the southern Sahel, Southern Sudan, the Horn of Africa and the southwestern Arabian Peninsula. It migrates to lower latitudes - including central Congo and northern Tanzania. A rather plain looking nightjar with grey-brown, brown, and rufous morphs. Males have white spots on primaries, large white corners to tail, and no white on the throat Females have buffy-brown wing spots, and no white on the tail.
The fiery-necked nightjar is a species of nightjar in the family Caprimulgidae, which occurs in Africa south of the equator. Its distinctive and frequently uttered call is rendered as 'good-lord-deliver-us'. It is replaced in the tropics by a near relative, the black-shouldered nightjar. In addition to the latter, it forms a species complex with the Montane and Ruwenzori nightjars.
The slender-billed starling is a species of starling in the family Sturnidae. It is found in Burundi, Democratic Republic of the Congo, Eritrea, Ethiopia, Kenya, Malawi, Rwanda, Tanzania, Uganda, and Zambia.
The rattling cisticola is a species of bird in the family Cisticolidae which is native to Africa south of the equator, and parts of East Africa. It is a common to abundant species in open savanna and scrubland habitats, whether in arid, moist or upland regions. Especially during summer, it is highly conspicuous due to its strident and repetitive call-notes from prominent perches.
The stout cisticola is a species of bird in the family Cisticolidae. It is found in Angola, Burundi, Cameroon, Republic of the Congo, Democratic Republic of the Congo, Eritrea, Ethiopia, Kenya, Nigeria, Rwanda, South Sudan, Tanzania, Uganda, and Zambia. Its natural habitats are boreal forest, moist savanna, and subtropical or tropical high-altitude grassland.
The white-browed scrub robin, also known as the red-backed scrub-robin, is a species of bird in the family Muscicapidae. It is native to sub-Saharan Africa, especially East and southern Africa. Within range, its Turdus-like song is one of the often-heard sounds of the bush. The flitting of the tail is characteristic of this species, but also of some near relatives.
The copper sunbird is a species of passerine bird in the family Nectariniidae. It is native to tropical Africa, its range extending from Senegal and Guinea in the west to South Sudan and Kenya in the east, and southwards to Angola, Zambia, Zimbabwe and Mozambique.
The baglafecht weaver is a species of weaver bird from the family Ploceidae which is found in eastern and central Africa. There are several disjunct populations with distinguishable plumage patterns. Only some races display a discrete non-breeding plumage.
The African hill babbler is a species of bird in the family Sylviidae.
The red-fronted prinia, also known as the red-fronted warbler and the red-faced apalis, is a species of bird in the family Cisticolidae. It is found in Chad, Djibouti, Eritrea, Ethiopia, Kenya, Somalia, Sudan, Tanzania, and Uganda. Its natural habitat is dry savanna.
The marsh tchagra or blackcap bush-shrike is a species of passerine bird placed in the monotypic genus Bocagia in the family Malaconotidae. It is native to marshes in the tropics and subtropics of Africa. It is sometimes placed in the genus Tchagra.
The northern yellow white-eye, formerly the African yellow white-eye, is a species of bird in the family Zosteropidae. It is found across sub-Saharan Africa, from Senegal in the west across to southern Sudan in the east and south to northern Angola.
The olive woodpecker is a species of bird in the woodpecker family Picidae.
The white-winged widowbird is a species of passerine bird in the family Ploceidae native to Africa south of the Sahara. It is highly sexually dimorphic in its breeding season, during which the male's yellow plumage turns dark and he gains more white feathers, contrasting with the female's predominantly pale coloration. Three subspecies are recognised.
