Western tree hyrax range |
The western tree hyrax (Dendrohyrax dorsalis), also called the western tree dassie or Beecroft's tree hyrax, is a species of tree hyrax within the family Procaviidae. It can be distinguished from other hyraxes by short coarse fur, presence of white patch of fur beneath the chin, lack of hair on the rostrum, and lower crowns of the cheek teeth compared to other members of the same genus. [3]
The western tree hyrax is similar in appearance to a large guinea pig. It has a head-and-body length of between 440 and 570 mm (17.3 and 22.4 in) and a stumpy tail. The pelage is thick and coarse, with a few yellowish hairs scattered among the dark brown and blackish ones; pale individuals with cream-coloured coats have also been observed. Scattered long sensory hairs similar to whiskers are present in the coat. The snout is free from fur, the ears are small and rounded and sometimes tipped with white, and the chin bears a white spot. There is a dorsal scent gland up to 70 mm (2.8 in) long in the centre of the back, surrounded by a yellowish patch of fur. [4]
Western tree hyraxes tend to be solitary, and only occasionally are found in groups of two or three. They are nocturnal and generally feed at night. It has been noted that this species is an especially adept climber. In captivity they have been observed to climb up the edge of an open door with ease, as well as being able to quickly scale smooth tree trunks. They are aided in climbing with their black, pliant footpads with numerous ridges. Captive animals were observed using their teeth to help hold on to wires and vines while climbing. [5]
The gestation period is about eight months with a litter size one or two young. [4]
Common predators of the western tree hyrax are eagles, leopards, hawks, servals, pythons, and golden cats, in addition to occasionally being hunted by humans for food. In Bossou, Guinea, one notable ecological association with chimpanzees occurs. A chimpanzee at Bossou was observed capturing a western tree hyrax, carrying it to her nest, and sleeping with and grooming it. This suggests that chimpanzees in Bossou may not regard hyraxes as a prey animal. [6]
The western tree hyrax is found in West and Central Africa: Benin, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Nigeria, Rwanda, Senegal, Sierra Leone, South Sudan, Togo, Uganda, and possibly Niger. Its natural habitats are subtropical or tropical moist lowland forests, moist savanna, and rocky areas. [2]
The rock hyrax, also called dassie, doop, Cape hyrax, rock rabbit, and coney, is a medium-sized terrestrial mammal native to Africa and the Middle East. Commonly referred to in South Africa as the dassie, it is one of the five living species of the order Hyracoidea, and the only one in the genus Procavia. Rock hyraxes weigh 4–5 kg (8.8–11.0 lb) and have short ears.
The Angolan long-eared bat is a species of vesper bat in the Vespertilionidae family. It can be found in moist savanna in Angola and Democratic Republic of the Congo.
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.
The copper woolly bat is a species of vesper bat. It is found in Cameroon, Democratic Republic of the Congo, Ivory Coast, and Guinea. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and subtropical or tropical swamps. It is threatened by habitat loss.
The Cameroon climbing mouse is a species of rodent in the family Nesomyidae which is endemic to the montane grasslands on three mountains in Cameroon.
The southern needle-clawed bushbaby is a species of strepsirrhine primate in the family Galagidae. Found in Cameroon, Central African Republic, Republic of the Congo, and possibly Democratic Republic of the Congo, its natural habitat is tropical moist forests. While the species is not threatened or endangered, some local populations may be threatened by habitat destruction.
The Lady Burton's rope squirrel is a species of rodent in the family Sciuridae. It is found in Cameroon, Central African Republic, Republic of the Congo, Equatorial Guinea, and Gabon. Its natural habitats are tropical and subtropical moist broadleaf forests and subtropical or tropical moist montane forest. It is a common species with a wide range, and the International Union for Conservation of Nature has rated it as being of "least concern".
The red-legged sun squirrel is a species of rodent in the family Sciuridae, also commonly known as the isabelline red-legged sun squirrel. It is native to tropical western and central Africa where its range extends from Senegal in the west, through Nigeria and the Republic of Congo to Uganda and Tanzania in the east. Its natural habitats are subtropical or tropical moist lowland forests and moist savanna. This species is thought to be common and has a very wide distribution, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The forest giant squirrel or Stanger's squirrel is a species of rodent in the family Sciuridae found in Angola, Benin, Burundi, Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Kenya, Liberia, Nigeria, Rwanda, Sierra Leone, Tanzania, Togo, and Uganda.

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.
