Hildegarde's tomb bat range |
Hildegarde's tomb bat (Taphozous hildegardeae) is a species of sac-winged bat in the family Emballonuridae. [2] It is found near the coast in Kenya and Tanzania where it feeds in tropical dry forests and roosts in caves. It is a diurnal species and the International Union for Conservation of Nature has assessed its conservation status as "endangered". The specific name hildegardeae was given in honour of anthropologist Hildegarde Beatrice Hinde.
Hildegarde's tomb bat is a moderate-sized, sac-winged bat. The head has a long, pointed snout and a deep hollow between the eyes, which are large. The lower lip has a grooved protuberance and the ears are triangular and backward-pointing. There is no nose-leaf nor throat pouches. The wings are long and narrow. There is fur over the whole body, the dorsal surface being pale greyish-brown and the ventral surface white. Fully-grown males have a black throat patch; glands in this patch secrete fluids which tend to stain the fur on the chest yellowish-brown. The wing membranes are mainly white, with brown streaking at base. The tail is free, projecting from the upper surface of the interfemoral membrane. [3]
This bat is endemic to East Africa where it is restricted to the coastal strip of Kenya and Tanzania. Its range extends from the Tana River estuary in Kenya to Dar es Salaam in Tanzania, as well as the islands of Pemba and Zanzibar. It is dependent on caves or other underground locations for roosting, and on dry forests for feeding. [1] In general, these bats are resident, but a distinct population of larger and darker individuals in southeastern Kenya migrates every year to an unknown destination. [3]
Hildegarde's tomb bat is a diurnal species, hunting through the forests for grasshoppers, butterflies and moths, and roosting at night in caves and other underground locations, often sharing its roosts with the rather more common African sheath-tailed bat (Coleura afra). [1]
This bat has a relatively small range, with a total area of occurrence of 20,000 km2 (7,700 sq mi). It is known from about ten different locations within that range. The threats it faces include disturbance at its roosting caves, and the degradation of the forests in which it hunts. The International Union for Conservation of Nature has assessed its conservation status as being endangered. [1]
Emballonuridae is a family of microbats, many of which are referred to as sac-winged or sheath-tailed bats. They are widely distributed in tropical and subtropical regions around the world. The earliest fossil records are from the Eocene.
The white-throated round-eared bat is a South and Central American bat species found from Honduras to Bolivia, Paraguay and Brazil. It creates roosts inside the nests of the termite, Nasutitermes corniger. It thrives on a mainly insect-based diet, focusing on the surfaces of foliage to hunt, and also eats fruit and pollen. It has a very wide range and is a common species over much of that range, so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Schreber's yellow bat or the giant house bat, is a species of vesper bat. It is found in Benin, Democratic Republic of the Congo, Ivory Coast, Ghana, Kenya, Malawi, Mozambique, Nigeria, Senegal, Tanzania, Togo, and Zimbabwe. Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, and moist savanna. It is an uncommon species and its biology is poorly known. It was first described in 1774 by the German naturalist Johann Christian Daniel von Schreber, who named it Vespertilio nigrita. It was later transferred to the genus Scotophilus, making it Scotophilus nigrita.
Hildegarde's broad-headed mouse or Hildegarde's zelotomys, is a species of rodent in the family Muridae. It is found in Central Africa.
The yellow-bellied sheath-tailed bat, also known as the yellow-bellied sheathtail or yellow-bellied pouched bat, is a microbat species of the family Emballonuridae found extensively in Australia and less commonly in parts of Papua New Guinea.
The Papuan sheath-tailed bat is a species of bat in the family Emballonuridae which occurs at the Cape York Peninsula and New Guinea. The poorly known species hunts in open forests for night flying insects.
The naked-rumped pouched bat, also known as the pouched tomb bat, is a species of sac-winged bat in the family Emballonuridae.
Taphozous is a genus of the family Emballonuridae. The wide distribution of the genus includes several regions of Australia, Indonesia, Papua New Guinea and Africa. Taphozous comes from the Greek τάφος, meaning "a tomb". The common names for species include variants on sac-winged, sheathtail, or tomb bats.
The common sheathtail bat, is a bat in the family Emballonuridae, occurring in northern Australia.
Hill's sheath-tailed bat is a bat of the family Emballonuridae. They are found in the deserts of central Australia.
The Mauritian tomb bat is a species of sac-winged bat in the family Emballonuridae that is found in central and southern Africa and Madagascar. It was discovered in 1818 by Étienne Geoffroy Saint-Hilaire, and is characterized by an all-white ventral surface, grizzled dorsal coloration, and conical face. It has exceptionally good eyesight, a trait which is common in old world bats and enables it to find roosting locations. It has adapted itself to a wide range of habitats including subarid scrub to semi-tropical savanna and can be found throughout much of Africa south of the Sahara, including many of the surrounding islands. They often seek out refuge in cool dry areas. Mauritian tomb bats help control pest populations, including insects that carry human diseases. These bats tend to be nocturnal hunters and their normal prey consists of moths, butterflies, and termites. Not prone to large-scale roosting, T. mauritianus is most often spotted on the sides of buildings or on the trunks of trees in groups of around five individuals. They breed on average once or twice a year and rear usually one pup, though twins are occasionally reported. They usually deposit their hungry offspring in areas where they can feed ferociously, most often in berry bushes. This species is listed as least concern on the IUCN Red List due their wide distribution and stable population.
The black-bearded tomb bat is a species of sac-winged bat found in South and South East Asia.
The naked-rumped tomb bat is a species of sac-winged bat in the family Emballonuridae. Found in northern Africa, the Middle East, and southeastern Asia, its natural habitats are dry savanna, subtropical or tropical dry shrubland and forests, caves, and arid areas.
The Egyptian tomb bat is a species of sac-winged bat in the family Emballonuridae. It is a medium- to large-sized microbat with a mass of approximately 30 g (1.1 oz). It is an aerial insectivore, foraging in open space. Based on individuals captured in Ethiopia, it is thought to feed predominantly on Lepidoptera, but is also known to feed on Isoptera, Coleoptera and Orthoptera.
Hildegarde's shrew is a species of mammal in the family Soricidae. It is found in Burundi, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ethiopia, Kenya, Rwanda, and Tanzania. Considered by some authorities to be a subspecies of Crocidura gracilipes, it is now recognised as a separate species, with a diploid chromosome number of 2n = 52. This is one of three species of small mammal named by the British zoologist Oldfield Thomas in honour of anthropologist Hildegarde Beatrice Hinde.
The Ethiopian epauletted fruit bat is a species of megabat in the family Pteropodidae. It is found in Burundi, Chad, Republic of the Congo, Democratic Republic of the Congo, Eritrea, Ethiopia, Kenya, Malawi, Mozambique, Nigeria, Rwanda, Sudan, Tanzania, and Uganda. Its natural habitats are dry savanna and moist savanna. It is threatened by habitat destruction.

Darling's horseshoe bat is a species of bat in the family Rhinolophidae found in Africa. Its natural habitats are dry savanna, caves, and subterranean habitats.
Rüppell's horseshoe bat is a species of bat in the family Rhinolophidae found in Africa. Its natural habitats are subtropical or tropical dry forests, dry savanna, moist savanna, caves and other subterranean habitats. This species is quite common in parts of its range, and no specific threats have been recognised, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
