Sjöstedt's Barred Owlet
Sjöstedt's barred owlet (''Glaucidium sjostedti''), also known as Sjöstedt's owlet, is a species of owl in the family Strigidae from west central Africa. Description Sjöstedt's barred owlet is a small owl, which has a brown head, neck and upper back densely marked with thin, white bars, while the remainder of the upperparts are deep reddish brown. There is extensive barring on the breast, where many dark brown bars are set against the light cinnamon-brown background; the barring becomes more diffuse towards the lower belly and vent. It has a distinctive face, with bold, white eyebrows above bright yellow eyes. Juveniles resemble the adults, but are generally paler, with a yellow-brown cast to the underparts and faint barring on the upper breast, darkening to become chestnut around the throat. Voice Sjöstedt's barred owlet has a distinctive call which can be rendered as "''kroo-kroo-kroo''", which is most often made around dawn and dusk. Distribution and habitat Sjöstedt's ...

Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and Herpetology, herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum, Berlin, Natural History Museum of Berlin from 1874 to 1921. He was an expert on African birds, making a collecting expedition to West Africa in 1872 and 1873, and writing ''Die Vögel Afrikas'' (1900–05). He was also an expert on parrots, describing all species then known in his book ''Vogelbilder aus Fernen Zonen: Abbildungen und Beschreibungen der Papageien'' (illustrated by Gustav Mützel, 1839–1893). He also wrote ''Die Vögel der Bismarckinseln'' (1899). He was editor of the ''Journal für Ornithologie'' from 1894 to 1921. A number of birds are named after him, including Reichenow's woodpecker and Reichenow's firefinch. His son Eduard Reichenow was a famous protozoologist.

Mount Cameroon
Mount Cameroon is an active volcano in the Southwest Region of Cameroon next to the city of Buea near the Gulf of Guinea. Mount Cameroon is also known as Cameroon Mountain or Fako (the name of the higher of its two peaks) or by its indigenous name ''Mongo ma Ndemi'' ("Mountain of Greatness"). Mount Cameroon is ranked 22nd by topographic isolation. It is the highest point in sub-Saharan western and central Africa, the fourth-most prominent peak in Africa, and 31st-most prominent in the world. The mountain is part of the area of volcanic activity known as the Cameroon Volcanic Line, which also includes Lake Nyos, the site of a disaster in 1986. The most recent eruption occurred on February 3, 2012. Description Mount Cameroon is one of Africa's largest volcanoes, rising to above the coast of west Cameroon. Flora The mountain's natural vegetation varies with elevation. The main plant communities on the mountain include:''The Management Plan of the Mount Cameroon National ...

Birds Described In 1893
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 ...

Owls Of Sub-Saharan Africa
Owls are birds from the order Strigiformes (), which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl. Owls are divided into two families: the true (or typical) owl family, Strigidae, and the barn owl and bay owl family, Tytonidae. Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except the polar ice caps and some remote islands. A group of owls is called a "parliament". Anatomy Owls possess large, forward-facing eyes and ear-holes, a hawk-like beak, a flat face, and usually a conspicuous circle of feathers, a facial disc, around each eye. The feathers making up this disc can be adjusted to sharply focus sounds from varying d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glaucidium (owl)
Pygmy owls are members of the genus ''Glaucidium''. They belong to the typical owl family, Strigidae. The genus consists of 29 species distributed worldwide. These are mostly small owls, and some of the species are called "owlets". The genus includes nocturnal, diurnal, and crepuscular species. Birds in this genus mainly hunt large insects and other small prey. Taxonomy The genus ''Glaucidium'' was introduced in 1826 by the German zoologist Friedrich Boie. The type species was designated as the Eurasian pygmy owl by George Robert Gray in 1840. The genus name is from Ancient Greek ''glaukidion'' meaning "little owl" or "owlet". It is diminutive of ''glaux'' ''(γλαυξ)'' meaning "owl". A molecular phylogenetic study of the owls published in 2019 found that the widely distributed northern hawk-owl (''Surnia ulula'') is sister to the genus ''Glaucidium''. Species The genus contains 29 living species: * Eurasian pygmy owl (''Glaucidium passerinum'') * Pearl-spotted owlet ('' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Passerines
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three suborders: New Zealand wrens; Suboscines, primarily found in North and South America; and songbirds. Passerines originated in the Sou ...

Strigidae
The true owls or typical owls (family (biology), family Strigidae) are one of the two generally accepted families of owls, the other being the barn owls and bay owls (Tytonidae). This large family comprises 230 living or recently extinct species in 24 genus, genera. The Strigidae owls have a cosmopolitan distribution and are found on every continent except Antarctica. Morphology While typical owls (hereafter referred to simply as owls) vary greatly in size, with the smallest species, the elf owl, being a hundredth the size of the largest, the Eurasian eagle-owl and Blakiston's fish owl, owls generally share an extremely similar body plan.Marks, J.

Republic Of Congo
The Republic of the Congo, also known as Congo-Brazzaville, the Congo Republic or simply the Congo (the last ambiguously also referring to the neighbouring Democratic Republic of the Congo), is a country located on the western coast of Central Africa to the west of the Congo River. It is bordered to the west by Gabon, to the northwest by Cameroon, to the northeast by the Central African Republic, to the southeast by the Democratic Republic of the Congo, to the south by the Angolan exclave of Cabinda, and to the southwest by the Atlantic Ocean. The region was dominated by Bantu-speaking tribes at least 3,000 years ago, who built trade links leading into the Congo River basin. From the 13th century, the present-day territory was dominated by a confederation led by Vungu which included Kakongo and Ngoyo. Loango emerged in the 16th century. In the late 19th century France colonised the region and incorporated it into French Equatorial Africa. The Republic of the Congo was es ...
