Tchagra
The tchagras are passerine birds in the bushshrike family, which are closely related to the true shrikes in the family Laniidae, and were once included in that group. Description These are long-tailed birds, typically with a grey or grey-brown back, brown wings and grey and whitish underparts. The head pattern is distinctive, with a dark cap and black eyestripe separated by a white supercilium. The bill is strong and hooked. The male and female are similar in plumage in all tchagra species, but distinguishable from immature birds. These are solitary birds which tend to skulk low down or on the ground. They have distinctive whistled calls and can be readily tempted into sight by imitating the call, presumably because the tchagra is concerned that there is an intruder in its territory. These are species typically of scrub, open woodland, semi-desert and cultivation in sub- Saharan Africa. They hunt large insects from a low perch in a bush, and the larger species like black ...

Black-crowned Tchagra
The black-crowned tchagra (''Tchagra senegalus'') is a bushshrike. This family of passerine birds is closely related to the true shrikes in the family Laniidae, and was once included in that group. This species is found in the Arabian peninsula and most of Africa in scrub, open woodland, semi-desert and cultivation. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the black-crowned tchagra in his based on a specimen collected in Senegal. He used the French name and the Latin . The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. 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 previously described by Brisson ...

Bushshrike
The bushshrikes are smallish passerine birds. They were formerly classed with the true shrikes in the family Laniidae, but are now considered sufficiently distinctive to be separated from that group as the family Malaconotidae, a name that alludes to their fluffy back and rump feathers. Like their shrike-like relatives, the helmetshrikes, the bushshrikes have arisen in Africa in relatively recent times. The family is endemic to sub-Saharan Africa but completely absent from Madagascar, where the vangas are their closest relatives. They are found in scrub or open woodland, and less often in marshes, Afromontane or tropical forest. 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 quite secretive. Some bushshrikes have flamboyant displays. The male puffbacks puff out the loose feathers on their rump and lower back ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-streaked Tchagra
The three-streaked tchagra (''Tchagra jamesi'') is a species of bird in the family Malaconotidae, which is an uncommon resident of semi-desert regions in the eastern Afrotropics. The binomial of this bird commemorates the explorer Frank Linsly James, who also had the Frank James Memorial Hospital built in his honour. Range and habitat It is found in Ethiopia, Kenya, Somalia, South Sudan, Tanzania, and Uganda. Its natural habitats are dry savanna and subtropical or tropical dry shrubland. Description It is a small tchagra, measuring Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events. In other words, measurement is a process of determining how large or small a physical quantity is as compared ... 16–17 cm from bill tip to tail tip. They are distinct from other tchagra species in having a narrow, black median stripe over the crown, without any superciliary stripe. In addition the terti ...

Tchagra Tchagra
The southern tchagra (''Tchagra tchagra'') is a passerine bird found in dense scrub and coastal bush in southern and south-eastern South Africa and Eswatini. This species is a bushshrike, a group closely related to the true shrikes in the family Laniidae, and formerly included in that family. Identification The southern tchagra is 17–21 cm in length. It has a brown crown and black eye stripes separated by a broad white supercilium. The underparts are pale grey and the upperparts pale brown. The folded wings are chestnut and the tail is black, tipped white. The longish bill is black. The sexes are similar, but young birds are duller and have a buff stripe through the eye. This species is similar to the black-crowned tchagra, but that species is larger, and the adult, as its name implies, has a black rather than brown crown. An identification pitfall is that juvenile black-crowned tchagra has a brown crown. It can be separated from southern tchagra by its larger size, ...

Marsh Tchagra
The marsh tchagra or blackcap bush-shrike (''Bocagia minuta'') is a species of passerine bird placed in the monotypic genus ''Bocagia'' in the family Malaconotidae. It is native to marshes in the tropics and subtropics of Africa. It is sometimes placed in the genus ''Tchagra''. Taxonomy The marsh tchagra was described by the German ornithologist Gustav Hartlaub in 1858 and given the binomial name ''Telephonus minutus''. The species is now placed in the monotypic genus ''Bocagia'' that was introduced by the English ornithologist George Ernest Shelley in 1894. Three subspecies are recognised. * ''B. m. minuta'' (Hartlaub, 1858) – West Africa and African tropics: Sierra Leone to Ethiopia, west Kenya and northwest Tanzania * ''B. m. reichenowi'' ( Neumann, 1900) – east Tanzania, south Malawi, east Zimbabwe and Mozambique * ''B. m. anchietae'' (Bocage, 1869) – Angola to southwest Tanzania and north Malawi The subspecies ''B. m. anchietae'' is sometimes separated as Anchieta ...

José Alberto De Oliveira Anchieta
José Alberto de Oliveira Anchieta (variations José d'Anchieta, José Anchieta, José de Anchieta - b. October 9, 1832 in Lisbon, Kingdom of Portugal, d. September 14, 1897 in Caconda, Portuguese Angola) was a 19th-century Portuguese explorer and naturalist who, between 1866 and 1897, travelled extensively in Portuguese Angola, Africa, collecting animals and plants. His specimens from Angola and Mozambique were sent out to Portugal, where they were later examined by several zoologists and botanists, chiefly among them J.V. Barboza du Bocage. Life Anchieta was born in 1832, in Lisbon, and started his studies in mathematics at the University of Coimbra. Due to his fierce independence and eccentric character, however, he did not adapt well and moved to the Escola Politécnica de Lisboa (Polytechnic School of Lisbon). In 1857, one of his closest friends moved to Portuguese Cape Verde, a Portuguese colony and a group of islands in the Atlantic Ocean in West Africa, and Anchieta went ...
