Crowned Eagle
The crowned eagle, also known as the African crowned eagle or the crowned hawk-eagle (''Stephanoaetus coronatus''), is a large bird of prey found in sub-Saharan Africa; in Southern Africa it is restricted to eastern areas.Sinclair & Ryan (2003). ''Birds of Africa south of the Sahara''. Its preferred habitats are principally riparian woodlands and various forests. The crowned eagle is the only extant member of the genus ''Stephanoaetus''. A second species, the Malagasy crowned eagle (''Stephanoaetus mahery'') became extinct after humans settled on Madagascar.Goodman, Steven M. (1994). Proceedings of the Biological Society of Washington 107(3): 421–428 ISSN 0006-324''Description of a new species of subfossil eagle from Madagascar: ''Stephanoaetus'' (Aves: Falconiformes) From The Deposits Of Ampasambazimba''. At least 90 percent of the diet is mammalian; the usual prey taken by populations shows pronounced regional differences. Throughout its range the principal prey items are s ...

Ndumo Game Reserve
Ndumo Game Reserve is a small () South African game reserve located in the far northeast district of KwaZulu-Natal known as Maputaland. It is situated on the border with Mozambique where the Pongola River joins the Great Usutu River. It is adjacent to the Tembe Elephant Park. Ndumo is relatively remote, being over from Durban. The town of Mkuze is away. Ndumo hosts a diverse range of habitats including sand forest, dense riverine forest, floodplains, alluvial plains, reedbeds, grassland, broad-leaved and acacia woodlands and extremely dense thornveld. Ndumo is popular for its birdlife and despite its small size, the reserve has recorded in excess of 430 bird species including residents and seasonal migrants. The park's abundance of pans, floodplains and rivers (Pongola & Usutu) provide suitable habitat for many aquatic species. The Maputaland area in general is relatively rich in birdlife due to ecosystem diversity as well as its geographical location: the area forms the southern ...

Chevrotain
Chevrotains, or mouse-deer, are small even-toed ungulates that make up the family Tragulidae, the only extant members of the infraorder Tragulina. The 10 extant species are placed in three genera, but several species also are known only from fossils. The extant species are found in forests in South and Southeast Asia, with a single species, the water chevrotain, in the rainforests of Central and West Africa. They are solitary or live in pairs, and feed almost exclusively on plant material. Chevrotains are the smallest hoofed mammals in the world. The Asian species weigh between , while the African chevrotain is considerably larger at . With an average length of and an average height of , the Java mouse-deer is the smallest extant (living) ungulate or hoofed mammal, as well as the smallest extant even-toed ungulate. In November 2019, conservation scientists announced that they had photographed silver-backed chevrotains (''Tragulus versicolor'') in a Vietnamese for ...

Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Africa
Although tropical Africa is mostly familiar to the West for its rainforests, this biogeographic realm of Africa is far more diverse. While the tropics are thought of as regions with hot moist climates, which are caused by latitude and the tropical rain belt, the geology of areas, particularly mountain chains, and geographical relation to continental and regional scale winds impact the overall areas , also, making the tropics run from arid to humid in West Africa. The area is currently experiencing the negative effects of rapid human population growth.Zinkina J., Korotayev A.br>Explosive Population Growth in Tropical Africa: Crucial Omission in Development Forecasts (Emerging Risks and Way Out). ''World Futures'' 70/2 (2014): 120–139 Overview Tropical rainforests are moist forests of semi-deciduous plants distributed across nine West African countries. Institute for Sea Research conducted a temperature record dating back 700,000 years. Several conservation and development dem ...

Harpy Eagle
The harpy eagle (''Harpia harpyja'') is a neotropical species of eagle. It is also called the American harpy eagle to distinguish it from the Papuan eagle, which is sometimes known as the New Guinea harpy eagle or Papuan harpy eagle. It is the largest and most powerful raptor found throughout its range, and among the largest extant species of eagles in the world. It usually inhabits tropical lowland rainforests in the upper (emergent) canopy layer. Destruction of its natural habitat has caused it to vanish from many parts of its former range, and it is nearly extirpated from much of Central America. In Brazil, the harpy eagle is also known as royal-hawk (in pt, gavião-real). The genus ''Harpia'', together with '' Harpyopsis'' and '' Morphnus'', form the subfamily Harpiinae. Taxonomy The harpy eagle was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' as ''Vultur harpyja'', after the mythological beast harpy. The only member of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sooty Mangabey
The sooty mangabey (''Cercocebus atys'') is an Old World monkey found in forests from Senegal in a margin along the coast down to the Ivory Coast. Habitat and ecology The sooty mangabey is native to tropical West Africa, being found in Guinea, Guinea-Bissau, Liberia, Senegal, Sierra Leone, and Ivory Coast. Sooty mangabeys inhabit both Old growth forest, old growth and secondary forests as well as in flooded, dry, swamp, mangrove, and gallery forests. Sooty mangabeys are Terrestrial animal, terrestrial omnivores, typically spending around 75% of their overall time on the ground (~85% of travel time and ~71% of foraging time). In their foraging behaviors, sooty mangabeys typically consume fruits (~20% of diet), invertebrates (~13% of diet), and nuts and seeds (>55% of diet). In acquiring nuts, sooty mangabeys have been observed scavenging the remains of Coula edulis, coula and Panda oleosa, panda nuts cracked by chimpanzees and red river hogs, potentially using either the sound of c ...

Bushbuck
The Cape bushbuck (''Tragelaphus sylvaticus'') is a common and a widespread species of antelope in sub-Saharan Africa.Wronski T, Moodley Y. (2009)Bushbuck, harnessed antelope or both? ''Gnusletter'', 28(1):18-19. Bushbuck are found in a wide range of habitats, such as rain forests, montane forests, forest-savanna mosaic, savanna, bushveld, and woodland. Bushbuck stand about at the shoulder and weigh from . They are generally solitary, territorial browsers. Taxonomy The taxonomy of bushbuck, and of the Tragelaphini tribe in general, has been contested. Bushbuck have been fractured into over 40 subspecies in the past. mtDNA profiles of a large number of samples were resolved in 2009 as belonging to 19 groups, some corresponding to previously described subspecies, while others were previously unrecognised and remained unnamed. These groups were then organised into two taxa - a nominate northern subspecies (''T. s. scriptus'') and a southern subspecies ''T. s. sylvaticus''. In the ...

Martial Eagle
The martial eagle (''Polemaetus bellicosus'') is a large eagle native to sub-Saharan Africa.Ferguson-Lees & Christie, ''Raptors of the World''. Houghton Mifflin Company (2001), . It is the only member of the genus ''Polemaetus''. A species of the booted eagle subfamily (Aquilinae), it has feathering over its tarsus. One of the largest and most powerful species of booted eagle, it is a fairly opportunistic predator that varies its prey selection between mammals, birds and reptiles. It is one of few eagle species known to hunt primarily from a high soar, by stooping on its quarry.Steyn, P. (1983). ''Birds of prey of southern Africa: Their identification and life histories''. Croom Helm, Beckenham (UK). 1983. An inhabitant of wooded belts of otherwise open savanna, this species has shown a precipitous decline in the last few centuries due to a variety of factors. The martial eagle is one of the most persecuted bird species in the world. Due to its habit of taking livestock and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...
