Retz's helmetshrike (Prionops retzii) is a species of bird in the helmetshrike family Vangidae, formerly usually included in the Malaconotidae.
Four subspecies are recognized: [2] [3]
It is found in Angola, Botswana, DRC, Eswatini, Kenya, Malawi, Mozambique, Namibia, Somalia, South Africa, Tanzania, Zambia, and Zimbabwe. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical mangrove forests, and subtropical or tropical moist shrubland.
The family Vangidae comprises a group of often shrike-like medium-sized birds distributed from Asia to Africa, including the vangas of Madagascar to which the family owes its name. Many species in this family were previously classified elsewhere in other families. Recent molecular techniques made it possible to assign these species to Vangidae, thereby solving several taxonomic enigmas. The family contains 40 species divided into 21 genera.
Helmetshrikes are a family uniting some smallish to mid-sized songbird species. They were included with the true shrikes in the family Laniidae, later on split between several presumably closely related groups such as bushshrikes (Malaconotidae) and cuckooshrikes (Campephagidae), but are now considered sufficiently distinctive to be separated from that group into the family Vangidae.
The red-bellied paradise flycatcher, also known as the black-headed paradise flycatcher, is a medium-sized passerine bird of the family of monarch flycatchers. It is native to intra-tropical forests of Africa. The male bird is about 17 cm (7 in) long and has a black head, a mainly chestnut body, and a tail with streamers nearly twice as long as the body. The colouring is somewhat variable across the bird's range. Both females and juveniles lack the tail streamers and are a duller brown colour. It is closely related to the African paradise flycatcher, and the two can hybridise.
The tricolored parrotfinch is a species of estrildid finch found in Timor and the southern Moluccas. It has an estimated global extent of occurrence of 20,000 to 50,000 km2.
The slender-billed greenbul is a species in the monotypic genus Stelgidillas of the bulbul family of passerine birds. It is found in western and central Africa. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and subtropical or tropical moist montane forest.
The little greenbul is a species of the bulbul family of passerine birds. It is found in many parts of sub-Saharan Africa.
The eastern nicator is a species of songbird in the family Nicatoridae. It is found in Eswatini, Kenya, Malawi, Mozambique, Somalia, South Africa, Tanzania, Zambia, and Zimbabwe. Its natural habitats are subtropical or tropical dry forests, dry savanna, and subtropical or tropical moist shrubland. It occurs south to around Mtunzini in northern KwaZulu-Natal, South Africa, and is regularly reported from lowland areas north through to east Africa, including inland areas along the Zambezi River.
Cabanis's greenbul, also known as Cabanis's bulbul, is a species of songbird in the bulbul family, Pycnonotidae. It is found in east-central and south-central Africa. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and subtropical or tropical moist shrubland.
The grey-olive greenbul, or grey-olive bulbul, is a species of songbird in the bulbul family, Pycnonotidae. It is found in eastern and south-central Africa. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and subtropical or tropical moist shrubland.
The yellow-streaked greenbul or yellow-streaked bulbul is a species of songbird in the bulbul family, Pycnonotidae. It is found in eastern and south-eastern Africa. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
The black-and-white shrike-flycatcher, also known as the black-and-white flycatcher or vanga flycatcher, is a species of passerine bird found in Africa. It was placed with the wattle-eyes and batises in the family Platysteiridae but is now considered to be more closely related to the helmetshrikes and woodshrikes.
The northern puffback is a species of bird in the family Malaconotidae. It is found in northern sub-Saharan Africa. It forms a superspecies with the black-backed puffback, which replaces it in eastern equatorial and southern Africa.
The yellow-crested helmetshrike or King Albert's helmetshrike is a species of bird in the Vanga family Vangidae. This large, striking helmetshrike is unique in its black plumage and bright yellow crest. Though this species has been encountered broadly across the mountains of the eastern Democratic Republic of the Congo, there is still much to learn about this species. It is rarely reported due to the majority of its distribution occurring in relatively remote regions within the Albertine Rift, an area with ongoing armed conflict.
The red-billed helmetshrike or chestnut-bellied helmetshrike is a species of bird in the Vanga family, Vangidae, formerly usually included in the Malaconotidae.
The Gabela helmetshrike is a species of bird in the Vanga family Vangidae, formerly usually included in the Malaconotidae.
The white-crested helmetshrike, also known as the white helmetshrike, is a species of passerine bird in the Vanga family Vangidae, formerly usually included in the Malaconotidae.
The gray-crested helmetshrike is a species of bird in the Vanga family Vangidae, formerly usually included in the Malaconotidae.
The chestnut-fronted helmetshrike is a species of bird in the Vanga family Vangidae, formerly usually included in the Malaconotidae.
The rufous-bellied helmetshrike or Gabon helmetshrike is a passerine bird belonging to the Vanga family, Vangidae. It inhabits tropical forest in Central Africa. It is sometimes included within the chestnut-bellied helmetshrike of West Africa.
The Cheringoma Plateau is a low plateau in Sofala Province of Mozambique. It lies mostly within Cheringoma, Muanza, and Marromeu districts.
