Leaf warblers are small insectivorous passerine birds belonging to the genus Phylloscopus.
The common chiffchaff, or simply the chiffchaff, is a common and widespread leaf warbler which breeds in open woodlands throughout northern and temperate Europe and the Palearctic.
The Iberian chiffchaff is a species of leaf warbler endemic to Portugal, Spain and North Africa, west of a line stretching roughly from the western Pyrenees via the mountains of central Spain to the Atlantic.
The mountain chiffchaff or eastern chiffchaff is a species of leaf warbler found in the Caucasus and Himalayas, and is an altitudinal migrant, moving to lower levels in winter. The nominate subspecies is similar to the Siberian chiffchaff, but with a finer darker bill, browner upperparts and buff flanks; its song is almost identical to the common chiffchaff, but the call is a weak psew. P. s. lorenzii is warmer and darker brown than the nominate race; it is sympatric with common chiffchaff in a small area in the Western Caucasus, but interbreeding occurs rarely, if ever. The mountain chiffchaff differs from tristis in vocalisations, external morphology and mtDNA sequences. Its two subspecies appear to be distinct vocally, and also show some difference in mtDNA sequences.
The willow warbler is a very common and widespread leaf warbler which breeds throughout northern and temperate Europe and the Palearctic, from Ireland east to the Anadyr River basin in eastern Siberia. It is strongly migratory, with almost all of the population wintering in sub-Saharan Africa.
The wood warbler is a common and widespread leaf warbler which breeds throughout northern and temperate Europe, and just into the extreme west of Asian Russia in the southern Ural Mountains.
Tree warblers are medium-sized warblers in the marsh- and tree-warbler family Acrocephalidae. They are found in Europe, Africa and western Asia. Until recently, they were all classified in the single genus Hippolais.
Pallas's leaf warbler or Pallas's warbler, is a bird that breeds in mountain forests from southern Siberia east to northern Mongolia and northeast China. It is named after the German zoologist Peter Simon Pallas, who first formally described it. This leaf warbler is strongly migratory, wintering mainly in south China and adjacent areas of southeast Asia, although in recent decades increasing numbers have been found in Europe in autumn.
The yellow-browed warbler is a leaf warbler which breeds in the east Palearctic. This warbler is strongly migratory and winters mainly in tropical South Asia and South-east Asia, but also in small numbers in western Europe. Like the rest of Phylloscopidae, it was formerly included in the Old World warbler assemblage.
The goldcrest is a very small passerine bird in the kinglet family. Its colourful golden crest feathers, as well as being called the "king of the birds" in European folklore, gives rise to its English and scientific names. The scientific name, R. regulus, means 'petty king' or prince. Several subspecies are recognised across the very large distribution range that includes much of the Palearctic and the islands of Macaronesia and Iceland. Birds from the north and east of its breeding range migrate to winter further south.
The common firecrest, also known as the firecrest, is a very small passerine bird in the kinglet family. It breeds in most of temperate Europe and northwestern Africa, and is partially migratory, with birds from central Europe wintering to the south and west of their breeding range. Firecrests in the Balearic Islands and north Africa are widely recognised as a separate subspecies, but the population on Madeira, previously also treated as a subspecies, is now treated as a distinct species, the Madeira firecrest, Regulus madeirensis. A fossil ancestor of the firecrest has been identified from a single wing bone.
Hume's leaf warbler or Hume's warbler is a small leaf warbler which breeds in the mountains of inner Asia. This warbler is migratory and winters mainly in India.
The western Bonelli's warbler is a warbler in the leaf warbler genus Phylloscopus. It was formerly regarded as the western subspecies of a wider "Bonelli's warbler" species, but as a result of modern taxonomic developments, they are now usually considered to be two species:
The Eastern Bonelli's warbler, sometimes known as Balkan warbler, is a "warbler" in the leaf warbler genus Phylloscopus. It was formerly regarded as the eastern subspecies of a wider "Bonelli's warbler" species, but as a result of modern taxonomic developments, they are now usually considered to be two species:
In biology, a ring species is a connected series of neighbouring populations, each of which interbreeds with closely sited related populations, but for which there exist at least two "end populations" in the series, which are too distantly related to interbreed, though there is a potential gene flow between each "linked" population and the next. Such non-breeding, though genetically connected, "end populations" may co-exist in the same region (sympatry) thus closing a "ring". The German term Rassenkreis, meaning a circle of races, is also used.
The eastern Canary Islands chiffchaff or Lanzarote Island chiffchaff is an extinct subspecies of the Canary Islands chiffchaff endemic to the island of Lanzarote – and possibly also Fuerteventura – in the Canary Islands, Spain.
The Canary Islands chiffchaff is a species of leaf warbler endemic to the Canary Islands, Spain. Sometimes the English name is spelled Canary Island chiffchaff.
Alan R. Dean is a British ornithologist with a special interest in gulls and warblers. He lives in Solihull, West Midlands.
The western Canary Islands chiffchaff is a small bird in the family Phylloscopidae. It is a subspecies of the Canary Islands chiffchaff found on the islands of El Hierro, La Palma, La Gomera, Tenerife and Gran Canaria in the Canary Islands, Spain.
Colin Bradshaw is an English physician, ornithologist, and musician who was chairman of the British Birds Rarities Committee from 1997 to 2008. He was active in the BBRC for almost 20 years, both as a committee member and as chairman. He is a medical doctor by profession and travels extensively for birding, and among his other hobbies are guitar, cricket, and photography.
