Lake Tana is the largest lake in Ethiopia and the source of the Blue Nile. Located in Amhara Region in the north-western Ethiopian Highlands, the lake is approximately 84 kilometres long and 66 kilometres wide, with a maximum depth of 15 metres, and an elevation of 1,788 metres. Lake Tana is fed by the Gilgel Abay, Reb and Gumara rivers. Its surface area ranges from 3,000 to 3,500 square kilometres, depending on season and rainfall. The lake level has been regulated since the construction of the control weir where the lake discharges into the Blue Nile. This controls the flow to the Blue Nile Falls and hydro-power station.
The Abyssinian roller, or Senegal roller, is a member of the roller family of birds which breeds across tropical Africa in a belt south of the Sahara, known as the Sahel. It is resident in the southern part of its range, but northern breeding populations are short-distance migrants, moving further south after the wet season.
The Ethiopian wolf, also known as the Simien jackal or Simien fox, is a canine native to the Ethiopian Highlands. In southeastern Ethiopia it is also known as the horse jackal. It is similar to the coyote in size and build, and is distinguished by its long and narrow skull, and its red and white fur. Unlike most large canids, which are widespread, generalist feeders, the Ethiopian wolf is a highly specialised feeder of Afroalpine rodents with very specific habitat requirements. It is one of the world's rarest canids, and Africa's most endangered carnivore.
The Abyssinian ground hornbill or northern ground hornbill is an African bird, found north of the equator, and is one of two species of ground hornbill. It is the second largest species of African hornbill, only surpassed by the slightly larger southern ground hornbill.
The Abyssinian owl or African long-eared owl is a medium-sized true owl.
The Abyssinian grass rat is a species of rodent in the family Muridae. It is found in Ethiopia. Its natural habitats are subtropical or tropical high-altitude grassland, arable land, and pastureland.
Erckel's spurfowl, also known as Erckel's francolin, is a species of game bird in the family Phasianidae.
The richness and variety of the wildlife of Ethiopia is dictated by the great diversity of terrain with wide variations in climate, soils, natural vegetation and settlement patterns. Ethiopia contains a vast highland complex of mountains and dissected plateaus divided by the Great Rift Valley, which runs generally southwest to northeast and is surrounded by lowlands, steppes, or semi-desert.
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 Abyssinian white-eye or white-breasted white-eye is a small passerine bird belonging to the genus Zosterops in the white-eye family Zosteropidae. It is native to north-east Africa and southern Arabia.
The Abyssinian woodpecker, also known as the golden-backed woodpecker or the golden-mantled woodpecker, is a species of bird in the woodpecker family, Picidae. It is native to Africa, where it occurs in Eritrea and Ethiopia. It appears to be a close relative of the cardinal woodpecker Dendropicos fuscescens.
The Ethiopian highland hare or Starck's hare is a medium-sized species of mammal in the rabbit and hare family, Leporidae. Its dorsal pelage is grizzled, buff white and spotted and streaked with black, while its belly fur is pure white and fluffy. It is endemic to the Ethiopian Highlands, ranging over the Afroalpine regions of the Shoa, Bale, and Arsi Provinces of Ethiopia. A herbivore, it mostly feeds on moorland grasses. The IUCN rates it as a species of least concern.
Crenigomphus abyssinicus is a species of dragonfly in the family Gomphidae. It is endemic to Ethiopia. Its natural habitat is rivers. It is threatened by habitat loss.
Chororapithecus is an extinct great ape from the Afar region of Ethiopia roughly 8 million years ago during the Late Miocene, comprising one species, C. abyssinicus. It is known from 9 isolated teeth discovered in a 2005–2007 survey of the Chorora Formation. The teeth are indistinguishable from those of gorillas in terms of absolute size and relative proportions, and it has been proposed to be an early member of Gorillini. However, this is controversial given the paucity of remains, and notable anatomical differences between Chororapithecus and gorilla teeth. The Kenyan ape Nakalipithecus has been proposed to be an ancestor of Chororapithecus or at least closely related. If correct, they would be the only identified fossil members of any modern non-human great ape lineage, and would push the gorilla–human last common ancestor from 8 million years ago to 10 million years ago. The teeth are adapted for processing tough plant fibres as well as hard, brittle food, and the formation is thought to represent a forested lakeside habitat.
The Abyssinian thrush is a passerine bird in the family Turdidae. It is also known as the African mountain thrush, northern olive thrush or Ethiopian thrush. In 2010, the species was confirmed as separate from the olive thrush due to genetic differences. Their ranges do not overlap. The southern and northern populations may be distinct species. The Abyssinian thrush is found in Eritrea and other parts of the Horn of Africa, as well as an area to the southeast extending from the African Great Lakes region to north eastern Zambia and Malawi.
Bulinus abyssinicus is a species of tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies.
Afronemacheilus is a genus of stone loaches endemic to Ethiopia.
