Mountain Sooty Boubou
The mountain sooty boubou (''Laniarius poensis''), western boubou or mountain boubou, is a species of bird in the family Malaconotidae. Taxonomy It was formerly considered conspecific with the Albertine sooty boubou (''Laniarius holomelas''), with Willard's sooty boubou (''Laniarius willardi''), and with Fülleborn's sooty boubou (''Laniarius fuelleborni''). Two subspecies are currently recognized: nominate ''L. p. poensis'', which is endemic to Bioko; and ''L. p. camerunensis'' which occurs on mainland Africa. Distribution and habitat It is found in the Cameroon line from Bioko, Equatorial Guinea north to Mount Oku, Cameroon and the Obudu Plateau, Nigeria. In the Cameroon highlands, it is found in montane forests, usually above 600 m in elevation. On Mount Cameroon, this species can occur at extremely low elevations on the windward slopes near the coast, with records from as low as c. 520 m above sea level. On both Bioko and Mt. Cameroon, this taxon is restricted to mont ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Boyd Alexander
Lieutenant Boyd Alexander (16 January 1873 – 2 April 1910) was an English officer in the British Army, as well as an explorer and ornithologist. Early life Boyd was the oldest son (with a twin brother) of Lt Colonel Boyd Francis Alexander. On his mother's side he was the grandson of David Wilson, the founder of the Great Eastern Hotel in Calcutta. He was born at Swifts Park at Cranbrook in Kent and educated at Radley and Sandhurst. Alexander was commissioned in a Militia battalion of the Rifle Brigade (Prince Consort's Own), and in October 1900 took up a commission in a regular battalion of that regiment. Promotion to lieutenant followed on 22 January 1902. During 1902 he visited the Gold Coast Colony, where he made an ornithological survey of that colony, and in September that year he left for the Bonin Islands to investigate their avifauna. African expedition Lieutenant Alexander was a member of an expedition which travelled across Africa from the Niger to the Nile ...

Birds Of Central 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 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. Birds ...

Laniarius
''Laniarius'' is a genus of brightly coloured, carnivorous passerine birds commonly known as boubous or gonoleks. Not to be confused with the similar-sounding genus ''Lanius'', they were formerly classed with the true shrikes in the family Laniidae, but they and related genera are now considered sufficiently distinctive to be separated from that group as the bush-shrike family Malaconotidae. This is an African group of species which are found in scrub or open woodland. They are similar in habits to shrikes, hunting insects and other small prey from a perch on a bush. Although similar in build to the shrikes, these tend to be either colourful species or largely black. Some species are also quite secretive. Taxonomy and systematics The genus ''Laniarius'' was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816 with the yellow-crowned gonolek as the type species. The closest relatives of the genus appear to be the genus '' Chlorophoneus''. Previously, memb ... [...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 ...

Windward And Leeward
Windward () and leeward () are terms used to describe the direction of the wind. Windward is ''upwind'' from the point of reference, i.e. towards the direction from which the wind is coming; leeward is ''downwind'' from the point of reference, i.e. along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side". If the vessel is heeling under the pressure of crosswind, the lee side will be the "lower side". During the Age of Sail, the term ''weather'' was used as a synonym for ''windward'' in some contexts, as in the ''weather gage''. Because it captures rain, the windward side of a mountain tends to be wet compared to the leeward it blocks. Origin The term "lee" comes from the middle-low German word // meaning "where the sea is not exposed to the wind" or "mild". The terms Luv and Lee (engl. Windward and Leeward) have been in use since the 17th century. Usage Windward and leeward directions (and the points ...
