It, and related species, are often called chats. The Red-flanked Bluetail or Orange-flanked Bush-Robin is a small Eurasian bird that breeds in the northern part of the range from Finland and NW Russia, to China and N Korea. Indeed, the Red-flanked Bluetail remains vulnerable as a breeding species in Finland – its population size is still rather small and it is restricted to undisturbed, mature forests – and it remains on Finland's Red List of threatened species. The Red-flanked Bluetail (Tarsiger cyanurus), also known as the Orange-flanked Bush-robin, is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. Now, a little over 40 years later, it is clear that the species' range has continued to expand in a westerly direction, but also that the overall upward trend, in both numbers and range, masks a good deal of fluctuation. time, the regular breeding range extended west from the taiga zone of Siberia and the northern parts of European Russia to a small area of northeast Finland. In 1973, HM drew BB readers' attention to the westward expansion of the Red-flanked Bluetail Tarsiger cyanurus (Mikkola 1973a,b). The changing status of this species in the rest of Europe over the same time period is discussed also. Based on this revision, the List of Birds of the Czech Republic was updated, currently including altogether 397 species in the occurrence categories A, B and C (as of 31 December 2018).ĭata are presented to illustrate the population increase and expansion in the breeding range of the Red-flanked Bluetail in Finland during the past 40 years. The character of occurrence of the respective species in the Czech Republic since the year 1800, with regard to its occurrence in the neighbouring countries, is also described. In the overview, a chronological list of accepted and rejected records (including rationale) and the international category of occurrence are given for each revised taxon. Identification as well as plausibility of the data on occurrence circumstances were assessed. Altogether 274 records were revised, many of them for the first time in the history of research of bird fauna of the Czech Republic. Purpose of this work, rare species were defined as those in which the number of occurrence records did not exceed 10. The revision was carried out by the authors of the paper in the years 2002–2019. Lynx Edicions, Barcelona.Results of a systematic revision of occurrence of rare bird species in the Czech Republic, both recent and historical data (including voucher material) since the year 1800, are summarised.

Orange-flanked Bush-robin ( Tarsiger cyanurus). ^ "Orange-flanked Bush-robin (Tarsiger cyanurus)".^ BirdLife species factsheet for Tarsiger rufilatus.^ Grimmett, Richard Inskipp, Tim (2003).The Himalayan bluetail is a short-distance altitudinal migrant species, breeding in the Himalaya in bush layer (dwarf rhododendron in wetter areas, deciduous bushes in drier) of conifer and mixed conifer-oak forest, main species fir ( Abies) but sometimes in areas with Picea smithiana or Pinus wallichiana/ Cupressus torulosa forest at 3000–4400 m, not penetrating beyond tree-line and in winters found at 1,500–2,500 m typically in broadleaf evergreen forest, dense dark undergrowth and thickets, clearings, treefall gaps with vine tangles, open woodland commonly seen along tracks favours ridges and mountain tops. It is closely related to the red-flanked bluetail and was generally treated as a subspecies of it in the past, but as well as differing in its migratory behaviour (the red-flanked bluetail is a long-distance migrant), it also differs in the more intense blue colour of the adult males and the greyer colour of the females and juveniles. While currently under review, this taxon is not current recognized as a species by BirdLife international. The Himalayan bluetail or Himalayan red-flanked bush-robin also called the Orange-flanked bush-robin ( Tarsiger rufilatus) is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher of Muscicapidae.
