Phylloscopus tristis

Siberian chiffchaff (Phylloscopus collybita tristis) is a leaf-warbler which is usually considered a subspecies of the common chiffchaff, but may be a species in its own right.

Contents

Range

Siberian chiffchaff breeds in Siberia east of the Pechora River and winters in the lower Himalayas. [1]

Status in Europe and North America

It is also regularly recorded in western Europe in winter, and it is likely that the numbers involved have been underestimated due to uncertainties over identification criteria, lack of good data and recording policies (Sweden and Finland only accept trapped birds). [2]

Because of their unfamiliar appearance, British records in the 1950s and 1960s were originally thought to be greenish warblers, and accepted as such by BBRC, the national rarities committee, until the records were reviewed in the 1980s. [3]

A Gambell, AK bird discovered by Alexander Lin-Moore and Ethan Goodman on June 5, 2015 and seen by many birders would be the 4th (or 5th?) reported in North America. [4]

Appearance and vocalisations

It is a dull bird, grey or brownish above and whitish below, with little yellow in the plumage, and the buff-white supercilium is often longer than in the western subspecies. It has a higher pitched suitsistsuisit song and a short high-pitched cheet call. [5] It is sometimes considered to be a full species due to its distinctive plumage and vocalisations, being similar to P. s. sindianus in these respects. [6] [7]

Taxonomy

Common chiffchaffs (of the nominate race) and Siberian chiffchaffs do not recognize each other's songs. [8] [9] Pending resolution of the status of the form fulvescens, which is found where the ranges of common chiffchaff (of the race abietinus) and Siberian chiffchaff connect and may [10] or may not [9] be a hybrid between these, tristis is maintained in P. collybita by most checklists. [11]

Leaf warbler Genus of birds

Leaf warblers are small insectivorous passerine birds belonging to the genus Phylloscopus.

Common chiffchaff Small migratory passerine bird found in Europe, Asia and north Africa

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.

Iberian chiffchaff Species of bird

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.

Mountain chiffchaff Species of bird

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.

Willow warbler Species of bird

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.

Wood warbler Species of bird

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 warbler Group of birds

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.

Pallass leaf warbler A small migratory passerine bird that breeds in northern Asia

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 for 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.

Yellow-browed warbler Species of bird

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.

Goldcrest Small passerine bird in the kinglet family

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 king or knight. 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.

Common firecrest Very small passerine bird from Europe and northwest Africa

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.

Western Bonellis warbler Species of bird

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, this species is now usually considered to be two species:

Eastern Bonellis warbler Species of bird

The Eastern Bonelli's 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, this species is now usually considered to be two species:

Ring 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. 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.
