Usambara Thrush
The Usambara thrush (''Turdus roehli''), also known as Roehl's thrush or Usambara olive thrush, is a species of thrush found in eastern Africa. Formerly, it was considered as a subspecies of the olive thrush, with which it is known to hybridize with, but is now recognised as a separate species. Description This medium-sized bird has a length of about 24 cm. It has a wing length between 117 and 131 mm, a culmen length between 20 and 24 mm and a tarsus length between 30,0 and 34,5 mm. It can reach a mass of at least 86 g. It occurs in the Pare and Usambara mountains of north-central Tanzania.

Anton Reichenow
Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the 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. Reichenow is known for his classification of birds into six groups, described as "shortwings, swimmers, stiltbirds, skinb ...

Thrush (bird)
The thrushes are a passerine bird family, Turdidae, with a worldwide distribution. The family was once much larger before biologists reclassified the former subfamily Saxicolinae, which includes the chats and European robins, as Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family. Characteristics Thrushes are plump, soft-plumaged, small to medium-sized birds, inhabiting wooded areas, and often feeding on the ground. The smallest thrush may be the forest rock thrush, at and . However, the shortwings, which have ambiguous alliances with both thrushes and Old World flycatchers, can be even smaller. The lesser shortwing averages . The largest thrush is the Great thrush at and , though the commonly recognized Blue whistling-thrush is an Old world flycatcher. The Amami thrush might, howe ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olive Thrush
The olive thrush (''Turdus olivaceus'') is, in its range, one of the most common members of the thrush family (Turdidae). It occurs in African highlands from southern Malawi and Mozambique in the north to the Cape of Good Hope in the south. It is a bird of forest and woodland, but has locally adapted to parks and large gardens in suburban areas. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the olive thrush in his ''Ornithologie'' based on a specimen collected from the Cape of Good Hope in South Africa. He used the French name ''Le merle olive du Cap de Bonne Espérance'' and the Latin ''Merula Olivacea Capitis Bonae Spei''. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his '' Systema Naturae'' for the twelfth edition, he added 240 species that had been previo ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pare Mountains
The Pare Mountains are a mountain range in northeastern Tanzania, located north of the Usambara Mountains. The mountains are administratively located in the Kilimanjaro Region, specifically in the Mwanga District and Same District. The North and South Pare mountain ranges reach a height of 2,463 meters at Shengena Peak. They are separated into North Pare Mountains and South Pare Mountains and are part of the Eastern Arc of mountains. The mountains are named after the indigenous Pare people, Pare people who reside there. Bird species in the Pare mountains include the endemic South Pare white-eye (''Zosterops winifredae''), the mountain buzzard (''Buteo oreophilus''), olive woodpecker (''Mesopicos griseocephalus''), moustached tinkerbird (''Pogoniulus leucomystax''), and the African hill babbler (''Pseudoalcippe abyssinica'').

Usambara Mountains
The Usambara Mountains of northeastern Tanzania in tropical East Africa, comprise the easternmost ranges of the Eastern Arc Mountains. The ranges of approximately long and about half that wide, are situated in the Lushoto District of the Tanga Region. They were formed nearly two million years ago by faulting and uplifting, and are composed of Precambrian metamorphic rocks. They are split into two sub-ranges; the West Usambaras being higher than the East Usambaras, which are nearer the coast and receive more rainfall. The mountains are clad in virgin tropical rainforest which has been isolated for a long period and they are a centre of endemism. Historically they were inhabited by Bantu, Shambaa, and Maasai people but in the eighteenth century, a Shambaa kingdom was founded by Mbegha. The kingdom eventually fell apart after a succession struggle in 1862. German colonists settled in the area which was to become German East Africa, and after World War I it became part of the ...

Turdus
True thrushes are medium-sized mostly insectivorous or omnivorous birds in the genus ''Turdus'' of the wider thrush family, Turdidae. The genus name ''Turdus'' is Latin for "thrush". The term " thrush" is used for many other birds of the family Turdidae as well as for a number of species belonging to several other families. The genus has a cosmopolitan distribution, with species in the Americas, Europe, Asia, Africa and Australia. Several species have also colonised some oceanic islands, and two species have been introduced to New Zealand. Some New World species are called ''robins'', the most well known of which is the American robin. Several species are migratory. While some species are often split out of ''Turdus'', the two small thrushes formerly separated in ''Platycichla'' by many authors have been restored to the present genus in recent years. Taxonomy and systematics The genus ''Turdus'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth editi ...

Endemic Birds Of Tanzania
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
