Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past ten years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. A smaller number of warblers, together with some babblers formerly placed in the family Timaliidae and the parrotbills, are retained in a much smaller family Sylviidae.
The typical warblers are small birds belonging to the genus Sylvia in the "Old World warbler" family Sylviidae.
The Eurasian blackcap, usually known simply as the blackcap, is a common and widespread typical warbler. It has mainly olive-grey upperparts and pale grey underparts, and differences across the five subspecies are small. Both sexes have a neat coloured cap to the head, black in the male and reddish-brown in the female. The male's typical song is a rich musical warbling, often ending in a loud high-pitched crescendo, but a simpler song is given in some isolated areas, such as valleys in the Alps. The blackcap's closest relative is the garden warbler, which looks quite different but has a similar song.
The garden warbler is a common and widespread small bird that breeds in most of Europe and in the Palearctic to western Siberia. It is a plain, long-winged and long-tailed typical warbler with brown upperparts and dull white underparts; the sexes are similar and juveniles resemble the adults. Its two subspecies differ only slightly and interbreed where their ranges overlap. Due to its lack of distinguishing features, this species can be confused with a number of other unstreaked warblers. The garden warbler's rich melodic song is similar to that of the blackcap, its closest relative, which competes with it for territory when nesting in the same woodland.
The barred warbler is a typical warbler which breeds across temperate regions of central and eastern Europe and western and central Asia. This passerine bird is strongly migratory, and winters in tropical eastern Africa.
The common whitethroat or greater whitethroat is a common and widespread typical warbler which breeds throughout Europe and across much of temperate western Asia. This small passerine bird is strongly migratory, and winters in tropical Africa, Arabia, and Pakistan.
The Sardinian warbler is a common and widespread typical warbler from the Mediterranean region. Like most Curruca species, it has distinct male and female plumages. The adult male has a grey back, whitish underparts, black head, white throat and red eyes. Plumages are somewhat variable even in the same locality, with the intensity of a reddish hue on upper- and/or underside that varies from absent to pronounced. The female is mainly brown above and buff below, with a grey head. The Sardinian warbler's song is fast and rattling, and is very characteristic of the Mediterranean areas where this bird breeds.
The western subalpine warbler is a small typical warbler which breeds in the southernmost areas of Europe and north-western Africa.
The Cyprus warbler is a typical warbler which breeds only on Cyprus. This small passerine bird is a short-distance migrant, and winters in Israel, Jordan and Egypt.
The lesser whitethroat is a common and widespread typical warbler which breeds in temperate Europe, except the southwest, and in the western and central Palearctic. This small passerine bird is strongly migratory, wintering in Africa just south of the Sahara, Arabia and India.
The Dartford warbler is a typical warbler from the warmer parts of western Europe and northwestern Africa. It is a small warbler with a long thin tail and a thin pointed bill. The adult male has grey-brown upperparts and is dull reddish-brown below except for the centre of the belly which has a dirty white patch. It has light speckles on the throat and a red eye-ring. The sexes are similar but the adult female is usually less grey above and paler below.
The melodious warbler is an Old World warbler in the tree warbler genus Hippolais. It breeds in southwest Europe and northwest Africa. It is migratory, wintering in sub-Saharan Africa. This small passerine bird is a species found in open woodland with bushes. Three to five eggs are laid in a nest in a tree or a bush. This is a common bird in many parts of its wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
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:
The African desert warbler is a typical warbler.
Rüppell's warbler is a typical warbler of the genus Curruca. It breeds in Greece, Turkey and neighbouring islands. It is migratory, wintering in northeast Africa. This is a rare vagrant to western Europe. The name is occasionally cited as "Rueppell's warbler".
The western Orphean warbler is a typical warbler of the genus Curruca. This species occurs in summer around the Mediterranean, through western Europe and extending into northwest Africa. It is migratory, wintering in Sub-Saharan Africa. It is a rare vagrant to northern and north-western Europe.
Marmora's warbler is a typical warbler in the Sylviidae family. The specific sarda is a Latin feminine form for a person from Sardinia.
The spectacled warbler is a species in the typical warbler genus, Curruca. The specific conspicillata is from Latin conspicillum, a place to look from, equivalent to "spectacled".
The eastern subalpine warbler is a small typical warbler which breeds in the southernmost areas of Europe. It was first described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name Motacilla cantillans. The specific cantillans is Latin for "warbling" from canere, "to sing".
Curruca is a genus of Sylviid warblers, best represented in Europe, Africa, and Asia. All of these species were formerly placed in the genus Sylvia.
