Ursula's Sunbird
Ursula's sunbird (''Cinnyris ursulae'') is a species of bird in the family Nectariniidae restricted to the continental and near-shore portions of the Cameroon line. Taxonomy Monotypic. Formerly considered a member of the genus ''Nectarinia'' along with other ''Cinnyris'' sunbirds. Habitat and Distribution Its natural habitat is subtropical or tropical moist montane forests. Its distribution is almost wholly restricted to the Cameroonian Highlands forests and Mount Cameroon and Bioko montane forests ecoregions, occurring in Nigeria, Cameroon, and Equatorial Guinea (specifically, on Bioko). It is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ....

Birds Described In 1903
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, ...

Cinnyris
''Cinnyris'' is a genus of sunbirds. Its members are sometimes included in ''Nectarinia''. They are generally known as double-collared sunbirds because the fringe of their bib usually includes a band of contrastingly coloured feathers. The sunbirds are a group of very small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed. Taxonomy The genus ''Cinnyris'' was introduced by the French naturalist Georges Cuvier in 1816. The type species was designated as "''Certhia splendida'' George Shaw (biologist), Shaw" by George Robert Gray in 1855. This taxon is a junior synonym of ''Certhia coccinigaster'' described by John Latham (ornithologist), John Latham in 1801. This is now the splendid sunbird. The name ''Cinnyris'' is from the Ancient Greek κιννυρις (''kinnyris''), an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Cameroon And Bioko Montane Forests
The Mount Cameroon and Bioko montane forests is a tropical moist broadleaf forest ecoregion in central Africa. It occupies the upper slopes of coastal Mount Cameroon in Cameroon, and the mountains of nearby Bioko island in Equatorial Guinea. Geography The ecoregion includes the distinct montane forests on the higher elevations of two volcanic peaks, Mount Cameroon, which lies in Cameroon near the coast, and Bioko, a volcanic island to the southwest in Equatorial Guinea. The montane forests occur as low as 500 meters elevation on Mount Cameroon. They also occur above 1500 meters elevation on three peaks on Bioko, Pico Basilé (3,011 meters elevation), Gran Caldera de Luba (2,261 m), and Pico Biao (2,009 m). The montane forests are surrounded at lower elevations by the Cross-Sanaga-Bioko coastal forests ecoregion. Both Bioko and Mount Cameroon are part of the Cameroon Volcanic Line, a line of volcanoes that runs northeast-southwest across the Cameroon Highlands and extending i ...
