Grauer's swamp warbler (Bradypterus graueri) is a species of Old World warbler in the family Locustellidae. It is found in Burundi, Democratic Republic of the Congo, Rwanda, and Uganda. Its natural habitats are freshwater lakes and freshwater marshes. It is threatened by habitat loss.
The Grauer's swamp warbler is endemic to the Albertine Rift and is found in montane swamps above 1900m. An investigation of the species population genetic structure revealed three clades across this region: clade 1, Virunga Volcanoes and Kigezi Highlands; clade 2, Rugege Highlands; and clade 3, Kahuzi-Biega Highlands (with clades 2 and 3 being sister groups). The divergence between these clades is thought to be a result of landscape dynamics and a historic period of aridity. [2]
The name commemorates the German zoologist Rudolf Grauer who collected natural history specimens in the Belgian Congo. [3]
Bradypterus is a genus of small insectivorous songbirds ("warblers") in the newly recognized grass warbler family (Locustellidae). They were formerly placed in the Sylviidae, which at that time was a wastebin taxon for the warbler-like Sylvioidea. The range of this genus extends through the warm regions from Africa around the Indian Ocean and far into Asia.
The Sri Lanka bush warbler, also known as Ceylon bush warbler or Palliser's warbler, is an Old World warbler which is an endemic resident breeder in Sri Lanka, where it is the only bush warbler.
The eastern gorilla is a critically endangered species of the genus Gorilla and the largest living primate. At present, the species is subdivided into two subspecies. There are 3,800 eastern lowland gorillas or Grauer’s gorillas and 1,000 mountain gorillas. Illegal hunting threatens the species.
The little rush warbler or African bush warbler is a species of Old World warbler in the family Locustellidae.
The white-winged swamp warbler, also known as the white-winged scrub-warbler, is a species of Old World warbler in the family Locustellidae. It is found in Burundi, Democratic Republic of the Congo, Kenya, Rwanda, Tanzania, Uganda, and Zambia. Its natural habitat is swamps.
The cinnamon bracken warbler is a species of Old World warbler in the family Locustellidae. It is found in Burundi, Democratic Republic of the Congo, Ethiopia, Kenya, Malawi, Mozambique, Rwanda, South Sudan, Tanzania, Uganda, and Zambia. Its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical moist shrubland.
The Dja River scrub warbler is a species of Old World warbler in the family Locustellidae. It is found in Cameroon, Central African Republic, and Gabon. Its natural habitat is swamps. It is threatened by habitat loss.
The evergreen forest warbler or Cameroon scrub-warbler is a grass warbler species in the family Locustellidae. It was formerly included in the "Old World warbler" assemblage.
Grauer's warbler is a species of Old World warbler in the family Acrocephalidae.
The red-faced woodland warbler is a species of leaf warbler in the family Phylloscopidae. It forms a superspecies with the closely related yellow-throated woodland warbler and the Laura's woodland warbler. Two subspecies are recognised, the nominate P. l. laetus ranges from Western Uganda and eastern Democratic Republic of the Congo, south through SW Uganda, western Rwanda and western Burundi. The second subspecies, P. l. schoutedeni, has a more restricted range, being confined to Mt Kabobo in eastern DRC. It is one of several species known as Albertine Rift Valley endemics. Overall the species has a total range of 77,000 square kilometres. Its natural habitat is highland forest between 1200–3100 m, especially in bamboo; it also occurs in areas of secondary forest.
Grauer's cuckooshrike is a species of bird in the family Campephagidae. It is found in Democratic Republic of the Congo and Uganda. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
The many-colored bushshrike or many-coloured bushshrike, is a species of bird in the bushshrike family, Malaconotidae.
Grauer's broadbill, also known as the African green broadbill, is a species of bird in the family Eurylaimidae, and is monotypic within the genus Pseudocalyptomena. Its name commemorates the German zoologist Rudolf Grauer who collected natural history specimens in the Belgian Congo.
The Kahuzi swamp shrew is a species of mammal in the family Soricidae found in the Democratic Republic of the Congo. Its natural habitat is swampland.
Grauer's large-headed shrew is a species of mammal in the family Soricidae. It is endemic to the Democratic Republic of the Congo. Its natural habitat is subtropical or tropical moist montane forests.
The wildlife of Rwanda comprising its flora and fauna, in prehistoric times, consisted of montane forest in one third the territory of present-day Rwanda. However, natural vegetation is now mostly restricted to the three National Parks and four small forest reserves, with terraced agriculture dominating the rest of the country.
The Rugezi Marsh is a protected area in Rwanda, covering 6,735 hectares. The wetland is one of headwaters of the Nile, situated in the Northern Province within the Buberuka Highlands. At 2,100 metres (6,900 ft), the marsh is a high altitude peat bog. Rugezi developed from an accumulation of organic materials within a quartzite rock-trapping water depression. In its natural state, Rugezi has been playing a significant ecological, hydrological, socio-economical, historic, and recreational role in Rwanda. It is also an Important Bird Area (IBA) recognized by the BirdLife International in 2001, and is reported to be the habitat of 43 species of birds within and in the surrounding areas of the marsh; the area of IBA is identified as ha8,500 hectares. The specific species of Grauer's swamp warbler and white-winged swamp warbler living together is reported as "unusual" by BirdLife International.
The Itombwe Mountains are a range of mountains in the South Kivu province of the Democratic Republic of the Congo (DRC). They run along the west shore of the northern part of Lake Tanganyika. They contain a vast area of contiguous montane forest and are home to a rich diversity of wildlife.
The Kahuzi-Biega National Park is a protected area near Bukavu town in eastern Democratic Republic of the Congo. It is situated near the western bank of Lake Kivu and the Rwandan border. Established in 1970 by the Belgian photographer and conservationist Adrien Deschryver, the park is named after two dormant volcanoes, Mount Kahuzi and Mount Biega, which are within its limits. With an area of 6,000 square kilometres (2,300 sq mi), Kahuzi-Biega is one of the biggest national parks in the country. Set in both mountainous and lowland terrain, it is one of the last refuges of the rare species of Eastern lowland gorilla, an endangered category under the IUCN Red List. The park is a UNESCO World Heritage Site, inscribed in 1980 for its unique biodiversity of rainforest habitat and its eastern lowland gorillas. In 1997, it was listed on the List of World Heritage in Danger because of the political instability of the region, an influx of refugees, and increasing wildlife exploitation.
