Rothschild's giraffe (Giraffa camelopardalis rothschildi) is a subspecies of the Northern giraffe. It is one of the most endangered distinct populations of giraffe, with 1,399 mature individuals estimated in the wild in 2018. [1]
The IUCN currently recognizes only one species of giraffe with nine subspecies. [1] Giraffa camelopardalis rothschildi is named after the Tring Museum's founder, Walter Rothschild, [2] and is also known as the Baringo giraffe, after the Lake Baringo area of Kenya, [3] or as the Ugandan giraffe. All of those living in the wild are in protected areas in Kenya and Uganda. In 2007, Rothschild's giraffe was proposed as a separate species from other giraffe. [4] In 2016, Rothschild's giraffe was proposed as conspecific with the Nubian giraffe (elevated to full species), but that taxonomy has not been widely adopted. [5]
The Rothschild's giraffe is easily distinguishable from other subspecies. The most obvious sign is in the coloring of the coat or pelt. Whereas the reticulated giraffe has very clearly defined dark patches with bright-whitish channels between them, Rothschild's giraffe more closely resembles the Masai giraffe. However, when compared to the Masai giraffe, the Rothschild's ecotype is paler, the orange-brown patches are less jagged and sharp in shape, and the connective channel is of a creamier hue compared to that seen on the reticulated giraffe. In addition, Rothschild's giraffe displays no markings on the lower leg, giving it the impression of wearing white stockings. [2]
Another distinguishing feature of Rothschild's giraffe, although harder to spot, is the number of ossicones on the head. This is the only Giraffa phenotype to be born with five ossicones. Two of these are the larger and more obvious ones at the top of the head, which are common to all giraffes. The third ossicone can often be seen in the center of the giraffe's forehead, and the other two are behind each ear. [6] They are also taller than many other populations, measuring up to 5.88 metres (19.3 feet) tall. [7] [8] They can weigh up to 2,500 pounds. [9]
Males are larger than females by a few hundred pounds [9] and their two largest ossicones are usually bald from sparring. They usually tend to be darker in colour than the females, although this is not a guaranteed sexing indicator.
The meat of the Rothschild giraffe is supposedly very sweet and its bones contain a specific type of fat that traditional cultures use as medicinal components. [10]
Isolated populations of Rothschild's giraffes live in savannahs, grasslands, and open woodlands of Uganda and Kenya. They are possibly regionally extinct from South Sudan and northeastern Democratic Republic of the Congo.
Rothschild's giraffes mate at any time of the year and have a gestation period of 14 to 16 months, typically giving birth to a single calf. They live in small herds, with males and females (and their calves) living separately, only mixing for mating. [11] The Rothschild's giraffes are tolerant of other animals around them as long as they don't feel threatened. For the most part, they are very friendly, but the males are known to engage in fights for mating. Since this species can mate all year long, those battles seem to be frequent. [12]
As of 2018, Rothschild's giraffe is classified as near threatened. Very few locations are left where Rothschild's giraffe can be seen in the wild, with notable spots being Lake Nakuru National Park in Kenya [13] and Murchison Falls National Park [14] in northern Uganda. Their predators are hyenas, lions, crocodiles, and leopards. [9]
Two dwarf giraffes standing only 9.5 feet (2.9 m) tall have been spotted in Murchison Falls National Park. Scientists speculate their dwarfism may have been caused by inbreeding due to species decline. [15]
Three Rothschild's giraffes were electrocuted by low-hanging power lines in Soysambu conservancy in Nakuru, Kenya. [16]
Various captive breeding programmes are in place – notably at the Giraffe Centre in Nairobi, Kenya – which aim to expand the gene pool in the wild population of Rothschild's giraffe. As of January 2011 [update] , more than 450 are kept in ISIS (international species information system) registered zoos (which does not include the Nairobi Giraffe Centre), making both it and the reticulated giraffe the most commonly kept phenotypes of Giraffa. [17]
The giraffe is a large African hoofed mammal belonging to the genus Giraffa. It is the tallest living terrestrial animal and the largest ruminant on Earth. Traditionally, giraffes were thought to be one species, Giraffa camelopardalis, with nine subspecies. Most recently, researchers proposed dividing them into up to eight extant species due to new research into their mitochondrial and nuclear DNA, as well as morphological measurements. Seven other extinct species of Giraffa are known from the fossil record.
The okapi, also known as the forest giraffe, Congolese giraffe and zebra giraffe, is an artiodactyl mammal that is endemic to the northeast Democratic Republic of the Congo in central Africa. However, non-invasive genetic identification has suggested that a population has occurred south-west of the Congo River as well. It is the only species in the genus Okapia. Although the okapi has striped markings reminiscent of zebras, it is most closely related to the giraffe. The okapi and the giraffe are the only living members of the family Giraffidae.
The Giraffidae are a family of ruminant artiodactyl mammals that share a common ancestor with deer and bovids. This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe and the okapi. Both are confined to sub-Saharan Africa: the giraffe to the open savannas, and the okapi to the dense rainforest of the Congo. The two genera look very different on first sight, but share a number of common features, including a long, dark-coloured tongue, lobed canine teeth, and horns covered in skin, called ossicones.
The Masai giraffe, also spelled Maasai giraffe, and sometimes called the Kilimanjaro giraffe, is a species or subspecies of giraffe. It is native to East Africa. The Masai giraffe can be found in central and southern Kenya and in Tanzania. It has distinctive jagged, irregular leaf-like blotches that extend from the hooves to its head. The Masai giraffe is currently the national animal of Tanzania.
The northern giraffe, also known as three-horned giraffe, is the type species of giraffe, G. camelopardalis, and is native to North Africa, although alternative taxonomic hypotheses have proposed the northern giraffe as a separate species.
Lake Nakuru is one of the Rift Valley lakes, located at an elevation of 1,754 m (5,755 ft) above sea level. It lies to the south of Nakuru, in the rift valley of Kenya and is protected by Lake Nakuru National Park.
Kidepo Valley National Park is a 1,442 square kilometres (557 sq mi) national park in the Karamoja region in northeast Uganda. Kidepo is rugged savannah, dominated by the 2,750 metres (9,020 ft) Mount Morungole and transected by the Kidepo and Narus rivers.
The wildlife of Kenya refers to its fauna. The diversity of Kenya's wildlife has garnered international fame, especially for its populations of large mammals. Mammal species include lion, cheetah hippopotamus, African buffalo, wildebeest (Connochaetes), African bush elephant, zebra (Equus), giraffe (Giraffa), and rhinoceros. Kenya has a very diverse population of birds, including flamingo and common ostrich.
The Kordofan giraffe is a species or subspecies of giraffe found in northern Cameroon, southern Chad, the Central African Republic, and possibly western Sudan. Historically some confusion has existed over the exact range limit of this subspecies compared to the West African giraffe, with populations in e.g. northern Cameroon formerly assigned to the latter. Genetic work has also revealed that all "West African giraffe" in European zoos are in fact Kordofan giraffe. It has been suggested that the Nigerian giraffe's ancestor dispersed from East to North Africa during the Quaternary period and thereafter migrated to its current Sahel distribution in West Africa in response to the development of the Sahara desert. Compared to most other subspecies, the Kordofan giraffe is relatively small at 3.8 to 4.7 meters, with more irregular spots on the inner legs. Its English name is a reference to Kordofan in Sudan. There are around 2,300 individuals living in the wild.
The West African giraffe, also known as the Niger giraffe or Nigerian giraffe, is a species or subspecies of the giraffe distinguished by its light colored spots. It is found in the Sahel of West Africa.
Knie's Kinderzoo is a zoo aimed for children. It is located in the Swiss municipality of Rapperswil.
Giraffe Manor is a small hotel in the Lang'ata suburb of Nairobi, Kenya which, together with its associated Giraffe Centre, serves as a home to a number of endangered Rothschild's giraffes, and operates a breeding programme to reintroduce breeding pairs back into the wild to secure the future of the subspecies.
The South African giraffe or Cape giraffe is a species or subspecies of giraffe found in South Africa, Namibia, Botswana, Zimbabwe, Eswatini and Mozambique. It has rounded or blotched spots, some with star-like extensions on a light tan background, running down to the hooves.
The Kigio Wildlife Conservancy is a protected Conservancy near Gilgil in the Great Rift Valley of Kenya. It is owned and operated by the local community.
Thornicroft's giraffe, also known as the Rhodesian giraffe or Luangwa giraffe, is a subspecies of giraffe. It is sometimes considered a species in its own right or a subspecies of the Masai giraffe. It is geographically isolated, occurring only in Zambia’s South Luangwa Valley. An estimated 550 live in the wild, with no captive populations. Its lifespan is 22 years for males and 28 years for females. The ecotype was originally named after Harry Scott Thornicroft, a commissioner in what was then North-Eastern Rhodesia and later Northern Rhodesia.
Ruma National Park is the only terrestrial park in Kenya's Nyanza Province. Dubbed the "Last Retreat of the Roan Antelope", the park protects the only indigenous population of rare roan antelopes within Kenya. At present, the population is on the verge of extinction with individual populations numbering approximately 40. The park was established in 1966 as Lambwe Valley Game Reserve. It was later renamed “Ruma” after one of Kenya's most powerful wizard, the much feared Gor Mahia who lived around the park. The park is located in the vast Lambwe Valley.
The reticulated giraffe is a species or subspecies of giraffe native to the Horn of Africa. It lives in Somalia, southern Ethiopia, and northern Kenya. There are approximately 8,500 individuals living in the wild.
The Nubian giraffe, also known as Baringo giraffe or Ugandan giraffe, is the nominate subspecies or species of giraffe. It is found in Ethiopia, Kenya, Uganda, South Sudan and Sudan. It is currently extinct in the wild of the Democratic Republic of Congo, Egypt and Eritrea. The Nubian giraffe used to be widespread in northeast Africa. The subspecies was listed as Critically Endangered by the IUCN in 2018 for the first time due to a 95% decline in the past three decades.
The Angolan giraffe, also known as the Namibian giraffe or smokey giraffe, is a species or subspecies of giraffe that is found in northern Namibia, south-western Zambia, Botswana, western Zimbabwe and since mid-2023 again in Angola.
The southern giraffe, also known as two-horned giraffe, is a species of giraffe native to Southern Africa. However, the IUCN currently recognizes only one species of giraffe with nine subspecies.
