Yellow-casqued Wattled Hornbill
The yellow-casqued hornbill (''Ceratogymna elata''), also known as the yellow-casqued wattled hornbill, is found in the rainforest of coastal regions of West Africa, for example in Côte d'Ivoire. It is threatened by habitat loss. The yellow-casqued hornbill is one of the largest birds of the West African forest, with adults weighing up to . They live mainly in the forest canopy, rarely feeding on the ground. They live in small family groups containing at least one adult male and female, with one or two immature birds, though they sometimes gather in larger flocks to exploit a major food supply such as an ant or termite nest. The birds are occasionally preyed upon by crowned hawk-eagles, and they respond to the presence of an eagle (sometimes indicated by its characteristic shriek) by mobbing – approaching it and emitting calls. Since the eagles depend on surprise to make a catch, this frequently causes them to leave the area. Recent research (Rainey et al., 2004) has ...

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch people, Dutch patrician, Zoology, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), illustrated by Pauline Rifer de Courcelles, Pauline Knip. He wrote ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna jap ...

Rainforest
Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic community, biotic species being Indigenous (ecology), indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "medicine chest (idiom), world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to #Deforestation, deforestation, the resulting habitat loss and air pollution, pollution of the atmosphere. Definition Rainforests are cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crowned Hawk-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 more easterly 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''), went extinct after early 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''.

Alarm Call
"Alarm Call" is a song recorded by Icelandic singer Björk for her third studio album ''Homogenic'' (1997).

Diana Monkey
The Diana monkey (''Cercopithecus diana'') is an Old World monkey found in the high canopy forests in Sierra Leone, Liberia, and western Côte d’Ivoire Named for its white brow which is said to resemble the bow of the Roman goddess Diana, this black-grey guenon has a white throat, crescent-shaped browband, ruff and beard. Taxonomy Two taxa formerly considered subspecies of the Diana monkey have recently been elevated to full species status: the Roloway monkey (''C. roloway'') is found in Côte d'Ivoire and Ghana, and the Dryas monkey (''C. dryas'') found in the DR Congo. Distribution This species can be found in West Africa, from Sierra Leone to Côte d'Ivoire. Habitat The Diana monkey is found in the primary forests, and does not thrive in secondary forests. The species is regarded as endangered by the IUCN as well as by the United States Fish and Wildlife Service, the chief dangers to them being habitat destruction (they are now virtually confined to coastal areas) a ...

Leopard
The leopard (''Panthera pardus'') is one of the five extant cat species in the genus ''Panthera''. It has a pale yellowish to dark golden fur with dark spots grouped in rosettes. Its body is slender and muscular reaching a length of with a long tail and a shoulder height of . Males typically weigh , and females . The leopard was first described in 1758, and several subspecies were proposed in the 19th and 20th centuries. Today, eight subspecies are recognised in its wide range in Africa and Asia. It initially evolved in Africa during the Early Pleistocene, before migrating into Eurasia around the Early–Middle Pleistocene transition. Leopards were formerly present across Europe, but became extinct in the region at around the end of the Late Pleistocene-early Holocene. The leopard is adapted to a variety of habitats ranging from rainforest to steppe, including arid and montane areas. It is an opportunistic predator, hunting mostly ungulates and primates. It relies on it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceratogymna
''Ceratogymna'' is a genus of large, primarily frugivorous hornbills (family Bucerotidae) found in the humid forests of Central Africa, Central and West Africa. They are sexually dimorphic: males are all black, while females have brown heads and a smaller :wikt:casque, casque.Kemp, A. C. (2001). Family Bucerotidae (Hornbills).

Unlike the members of the genus ''Bycanistes'', the two species in the genus ''Ceratogymna'' have extensive, primarily blue, bare facial skin and dewlap, and the only white in their plumage is in the tail (although the yellow-casqued wattled hornbill has slight whitish speckling on the neck). Species The members of the genus ''Bycanistes'' have been included in this genus, but today most authorities consider the two separate. References Ceratogymna, Bird genera Birds of ...

Birds Of West Africa
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furth ...
