Common Stonechat
Common stonechat is the name used for the ''Saxicola'' species ''Saxicola torquatus'' when this is treated in its broad sense. It is, however, now more widely considered to be a superspecies consisting of several related but distinct species, which are outwardly fairly similar but genetically distinct and replacing each other geographically without significant hybridisation:Urquhart, E., & Bowley, A. (2002): ''Stonechats. A Guide to the Genus Saxicola''. Christopher Helm, London. * African stonechat ''Saxicola torquatus'' in the strict sense * European stonechat ''Saxicola rubicola'' * Siberian stonechat ''Saxicola maurus'' * Amur stonechat ''Saxicola stejnegeri'' * Madagascar stonechat ''Saxicola sibilla'' Three other species, not previously included within the broad view of common stonechat, have also been shown to be members of the superspecies:Illera, J. C., Richardson, D. S., Helm, B., Atienza, J. C., & Emerson, B. C. (2008). Phylogenetic relationships, biogeography and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxicola Stejnegeri, Hanoi, Vietnam 4G4A3231 (cropped)
''Saxicola'' (Latin: ''saxum'', rock + ''incola'', dwelling in.), the stonechats or chats, is a genus of 15 species of small passerine birds restricted to the Old World. They are insectivores occurring in open scrubland and grassland with scattered small shrubs. Taxonomy The genus was introduced by the German naturalist Johann Matthäus Bechstein in 1802. The type species was subsequently designated as the European stonechat. The name ''Saxicola'' is from Latin ''saxum'', ''saxi'' "stone" and ''-cola'' "dweller". The genus was formerly included in the thrush family Turdidae, but as with several other related genera, has now been shown to be correctly classified in the Old World flycatcher family Muscicapidae, in which it is most closely related to the genera '' Oenanthe'' (wheatears) and '' Campicoloides''. Genetic and behavioural evidence has also resulted in several new species being accepted in the genus in recent years, most notably the splitting of the former broad "specie ...

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] |
Helm Identification Guides
The ''Helm Identification Guides'' are a series of books that identify groups of birds. The series include two types of guides, those that are: * Taxonomic, dealing with a particular family of birds on a worldwide scale—most early Helm Guides were this type, as well as many more-recent ones, although some later books deal with identification of such groups on a regional scale only (e.g., ''The Gulls Guide,'' which covers only species in Europe, Asia, and North America) * Geographic, including all bird species in an area (e.g., ''The Birds of the West Indies'') Early volumes were sometimes published under the Croom Helm or Christopher Helm imprints. In addition, a parallel set of guides, very similar in design, was published by Pica Press in the 1990s (marked ''Pica'' in the list below); Pica was later absorbed into A & C Black (now part of Bloomsbury Publishing Plc), and all guides are now marketed as a single series. Several of the books have won the British Birds ''Bird B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Stonechat
The African stonechat or common stonechat (''Saxicola torquatus'') is a species of the Old World flycatcher family (Muscicapidae), inhabiting sub-Saharan Africa and adjacent regions. Like the other chats, it was long assigned to the thrush family (Turdidae), to which the chats are convergent. Its scientific name refer to its appearance and habitat and means "collared rock-dweller": ''Saxicola'' from Latin ''saxum'' ("rock") + ''incola'' ("one who dwells in a place"), ''torquatus'', Latin for "collared". In the past ''S. torquatus'' usually referred to the entire "common stonechat" superspecies and some sources still keep it that way, but all available evidence strongly supports full species status for the European (''S. rubicola'') and the Siberian stonechat (''S. maurus'') of temperate Eurasia, in addition to the island-endemics Fuerteventura chat (''S. dacotiae'') and Réunion stonechat (''S. tectes'') which were never unequivocally accepted into ''S. torquatus''.

European Stonechat
The European stonechat (''Saxicola rubicola'') is a small passerine bird that was formerly classed as a subspecies of the common stonechat. Long considered a member of the thrush family, Turdidae, genetic evidence has placed it and its relatives in the Old World flycatcher family, Muscicapidae. Taxonomy and systematics The European stonechat was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae'' under the binomial name ''Motacilla rubicola''. This species is now placed in the genus ''Saxicola'' that was introduced by the German naturalist Johann Matthäus Bechstein in 1802. The English name derives from its call, sounding like two stones knocked together. The scientific name ''Saxicola'' means "rock-dweller", from Latin ''saxum'' meaning "a rock" and ''incola'' meaning "dwelling in". The specific epithet combines the Latin ''rubus'' meaning "brambles" with ''incola''. The subspecies name ''hibernans'' refers to ...

Siberian Stonechat
The Siberian stonechat or Asian stonechat (''Saxicola maurus'') is a recently validated species of the Old World flycatcher family (Muscicapidae). Like the other thrush-like flycatchers, it was often placed in the Turdidae in the past. It breeds in the East Palearctic including in easternmost Europe and winters in the Old World tropics. Description, systematics and taxonomy It resembles its closest living relative the European stonechat (''S. rubicola''), but is typically darker above and paler below, with a white rump and whiter underparts with less orange on the breast. The male in breeding plumage has black upperparts and head (lacking the brownish tones of the European stonechat), a conspicuous white collar, scapular patch and rump, and a restricted area of orange on the throat.Robertson (1977), Stoddart (1992), Urquhart & Bowley (2002) The female has pale brown upperparts and head, white neck patches (not a full collar), and a pale, unstreaked pinkish-yellow rump. Males i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amur Stonechat
The Amur stonechat or Stejneger's stonechat (''Saxicola stejnegeri'') is a species of stonechat native to eastern Asia. It breeds in central and eastern Siberia, Japan, Korea, northeastern China, and eastern Mongolia, and migrates south to southern China and Indochina in winter.Urquhart, E., & Bowley, A. (2002): ''Stonechats. A Guide to the Genus Saxicola''. Christopher Helm, London. It is a small bird 11.5–13 cm long, very closely similar to the Siberian stonechat in both plumage and behaviour, differing in only small details, notably having a slightly broader-based bill 4.7–5.7 mm wide (4.0–4.9 mm wide in Siberian stonechat) and slightly less white on the rump.Svensson, L. (1992). ''Identification Guide to European Passerines''. British Trust for Ornithology, Thetford. . Vagrants have been reported west to Great Britain, east to Alaska, and south to Borneo. Taxonomy Amur stonechat was generally considered a subspecies of either common stonechat (as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar Stonechat
The Madagascar stonechat (''Saxicola sibilla'') is a species of stonechat, endemic to Madagascar. It is a small bird, closely similar to the African stonechat in both plumage and behaviour, but distinguished from it by the more extensive black on the throat and minimal orange-red on the upper breast of the males.Urquhart, E., & Bowley, A. (2002): ''Stonechats. A Guide to the Genus Saxicola''. Christopher Helm, London. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Madagascar stonechat in his ''Ornithologie'' based on a specimen collected in Madagascar. He used the French name ''Le traquet de Madagascar'' and the Latin ''Rubetra Madagascariensis''. 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. ...
