Sylvia melanothorax
Tristram, 1872, En-Gedi, Palestine
The Cyprus Warbler (Sylvia melanothorax) is a typical warbler which breeds on Cyprus. This small passerine bird is a short-distance migrant, and winters in Israel, Jordan and Egypt.
Like most Sylvia species, it has distinct male and female plumages. The adult male is a small typical warbler with a grey back, black head, white malar streaks ("moustaches"), and, uniquely among typical warblers, underparts heavily streaked with black. The female is mainly grey above, with a greyer head, and whitish with only light spotting. The Cyprus Warbler's song is fast and rattling, and is similar to that of the Sardinian Warbler.
Together with Rüppell's Warbler it forms a superspecies with dark throats, white malar streaks and light remiges fringes. This in turn is related to the species of Mediterranean and Middle East Sylvia warblers that have a naked eye-ring, namely the Subalpine Warbler,Sardinian Warbler and Menetries' Warbler. Both groups have a white malar area, but this may not form a clear streak in the latter group; above the white, the heads of males are uniformly dark.(The Sylvia Monograph, A & C Black, London; Jønsson & Fjeldså 2006)
This is a bird of dry open country, often on hill slopes, with bushes for nesting. The nest is built in low shrub or gorse, and 3-5 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries.

Binomial name
Sylvia rueppelli
Temminck, 1823, Crete
The Rüppell's Warbler (Sylvia rueppelli) is a typical warbler of the genus Sylvia. It breeds in Greece, Turkey and neighbouring islands. It is migratory, wintering in north east Africa. This is a rare vagrant to western Europe. The name is occasionally cited as "Rueppell's Warbler".
It is a typical "sylvia" warbler, similar in size but slimmer than Sardinian Warbler. The adults have a plain grey back and paler grey underparts. The bill is fine and pointed, with brown legs and red eyes. The striking male has a black head and, usually, a black throat, separated by a white malar streak ("moustache"). Females have a pale throat, and the head is grey rather than black. Their grey back has a brownish tinge. The song is a slower, deeper rattle than that of Sardinian Warbler.
Together with the Cyprus Warbler it forms a superspecies with dark throats, white malar streaks and light remiges fringes. This in turn is related to the species of Mediterranean and Middle East Sylvia warblers that have a naked eye-ring, namely the Subalpine Warbler,Sardinian Warbler and Ménétries's Warbler. Both groups have a white malar area, but this may not form a clear streak in the latter group; above the white, the heads of males are uniformly dark.(Helbig 2001, Jønsson & Fjeldså 2006)
These small insectivorous passerine birds are found in thick thorny shrubs where they build their nests and lay four to six eggs.
The species is named after the German zoologist and explorer Eduard Rüppell (1794–1884).

(Gmelin, 1789)
Subspecies
2-6, see text
The Sardinian WarblerSylvia melanocephala, is a common and widespread typical warbler from the Mediterranean region.


Description

Like most Sylvia 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 varies from absent to (in some subspecies) 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.

Distribution and ecology


Sylvia melanocephala - MHNT
It breeds in the southernmost areas of Europe and just into Asia in Turkey and the eastern end of the Mediterranean. This small passerine bird, unlike most "warblers", is not particularly migratory, but some birds winter in north Africa, and it occurs as a vagrant well away from the breeding range, as far as Great Britain.
This is a bird of open country and cultivation, with bushes for nesting. The nest is built in low shrub or brambles, and 3-6 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries and other soft fruit.

Systematics

Together with Menetries' Warbler it forms a superspecies. Both thave white malar areas and light throats, and otherwise black theads in adult males, as well as a naked ring around the eye. The Subalpine Warbler, which seems the superspecies' closest relative, has a dark throat and breast and a dark gray upper head in males, but otherwise shares these characters. These three species are related to a dark-throated superspecies consisting of Rüppell's Warbler and the Cyprus Warbler, which also share the white malar area with blackish above.
This bird may be considered a superspecies, divided into the western Sylvia melanocephalaand Sylvia momus from the more arid regions of the Near East and adjacent Africa.

Subspecies

The geographical variation in the Sardinian Warbler conforms to some extent with Gloger's Rule, though not as strongly as in some other typical warblers. The validity of leucogastra and norissae is not accepted by some authors, and valverdei has been described very recently. On the other hand, leucogastra might be more than one subspecies.
  • Sylvia melanocephala melanocephala (Gmelin, 1789)
Iberia across the northern Mediterranean to western Turkey. Extends into the Maghreb from Iberia, and into Libya from Italy via Sicily. Migrates to the Sahel and oases in the Sahara in winter.
Large, long wings, tail tip rather pointed. A dark form, usually lacking any reddish in males but flanks extensively grey. Females' uppersides vary between deep olive brown and greyish olive.
  • Sylvia melanocephala leucogastra (Ledru, 1810) - often included in melanocephala; phylogenetic status requires review
Canary Islands, resident, probably some vagrancy between eastern islands and Maghreb.
Medium size, short-winged and large-billed. Tenerife and La Palma (western) birds are most distinct, being dark above with some rusty/beige hue on the underside in males. Eastern birds (Fuerteventura, Lanzarote and Gran Canaria) are more like melanocephalaand momus but differ in measurements.
  • Sylvia melanocephala momus (Hemprich & Ehrenberg, 1833)
Near East. Resident, some local movements.
Smallish, short-winged. Varies between brownish grey and rusty above; underside almost always has reddish hue. Females rusty to rusty olive.
  • Sylvia melanocephala norissae Nicoll, 1917Fayyum Warbler - probably only a local morph of momus
Nile Delta region. Extinct since around 1940.
Like momus, but tend to be very reddish.
  • Sylvia melanocephala valverdei Cabot & Urdiales, 2005 - recently split from melanocephala
From Tiznit (Morocco) south to the Tropic of Cancer, inland to the edge of the Sahara. Resident, but some seasonal movements.
Medium-sized, tail tip quite square. A very pure-colored form, the palest subspecies. Undersides clean white. Matte black cap in males. Juveniles decidedly sandy.

Sylvia cantillans
(Pallas, 1764, Italy)

Sylvia cantillans - MHNT
The Subalpine WarblerSylvia cantillans, is a small typical warbler which breeds in the southernmost areas of Europe and northwest Africa. This small passerine bird is migratory, and winters along the southern edge of the Sahara. It occurs as a vagrant well away from the breeding range, in both spring and autumn as far north as Great Britain.
Like most Sylvia  species, it has distinct male and female plumages. The adult male has a grey back and head, brick-red underparts, and white malar streaks ("moustaches"). The female is mainly brown above, with a greyer head, and whitish below with a pink flush. The Subalpine Warbler's song is fast and rattling, and is similar to the Lesser Whitethroat.
This bird seems to be related to the Sardinian Warbler-Menetries' Warbler superspecies. They all have white malar areas, the heads being dark above in adult males, and naked eye-rings. These three species are related to a superspecies consisting of Rüppell's Warbler and the Cyprus Warbler, which also share the white malar area with blackish above.(Shirihai et al. 2001,Jønsson & Fjeldså 2006 ) The Subalpine Warbler is divided into three distinct subspecies groups, which may possibly be sufficiently diverged to qualify as three separate species (Shirihai et al. 2001). The three groups have differing male plumages, distinctive calls, and are allopatric; further study is needed.
These groups are as follows (areas given below are breeding ranges; all forms winter in Africa):
  • Western Subalpine Warbler - subspecies cantillans, found in north-west and peninsular Italy, Sicily, southern France and Iberia, and inornata found in north-west Africa
  • Eastern Subalpine Warbler - subspecies albistriata, found from north-east Italy southeastwards to southern Turkey
  • Moltoni's (Subalpine) Warbler - subspecies moltonii, an endemic taxon of the western Mediterranean islands: Corsica, Sardinia, the Balearic Islands; and theLigurian Apennines
Eastern Subalpine Warbler differs from the nominate race by its deeper blue-grey upperparts, a blackish mask on the lores and ear-coverts, brick reddish-brown coloration confined to the throat and breast and sharply demarcated from a largely white belly, paler flanks and a wider white submoustachial stripe.
This is a bird of dry open country, often on hill slopes, with bushes for nesting. The nest is built in low shrub or gorse, and 3-5 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries.

Binomial name
Sylvia conspicillata
Temminck, 1820, Sardinia
The Spectacled Warbler (Sylvia conspicillata) is a species in the typical warbler genus Sylvia. It breeds in north west Africa, southwest Europe from Iberia to Italy, and then further east on the eastern Mediterranean islands and coastal regions. It is mainly resident in Africa, but other populations migrate to winter in more widely in north and west Africa and Egypt. This bird is a rare vagrant to northern and western Europe.
It also occurs in some Atlantic islands. The subspecies orbitalis has been proposed for those of the Cape Verde Islands. The presumed subspecies for the Madeira birds, bella is today usually included in this taxon, as are the birds of the Canary Islands, where the species is quite common except on El Hierro and known as zarzalero y ratonero (Álamo Tavio 1975).
These are very small "warblers" and are intermediate between Whitethroats and Tristram's Warbler in coloration. Spectacled Warblers are brown above and buff below, with chestnut wing patches and a white throat. Adult males have a grey head and the white eye ring which gives the species its name. Immature birds can be confused with both the Whitethroat and the Subalpine Warbler, and identification is difficult in the field. The song is a fast high warble.
About the precise relationships of this bird, not much can be said with certainty. It seems though as if its intermediate appearance, apart from the autapomorphic white eye ring, indicates its relationships reasonably well. It is not the closest living relative of at least Tristram's Warbler though.(Helbig 2001, Jønsson & Fjeldså 2006)
These small passerine birds are found in dry open country with bushes. 3-6 eggs are laid in a nest in a bush. Like their relatives, the Spectacled Warbler is insectivorous.

Marmora's WarblerSylvia sarda, is a typical warbler, genus Sylvia. It breeds on Mediterranean islands, typically including Corsica and Sardinia. The smaller Balearic Islands subspecies is increasingly given specific status as Balearic WarblerSylvia balearica. These two seem to form a superspecies which in turn groups with Tristram's Warbler and the Dartford Warbler (Helbig 2001, Jønsson & Fjeldså 2006). They are generally resident but some birds migrate south to winter in north Africa. They are rare vagrants to northern and western Europe.
These are small, long tailed, large-headed birds, overall very similar to their close relatives in thr Dartford Warbler group. Marmora's Warblers are grey above and below, lacking the brick-red underparts of the Dartford Warbler. Adult males have darker patches on the forehead and between the eye and the pointed bill. The legs and iris are red. The song is a fast rattle. Immature birds can be confused with young Dartford Warblers, which are also grey below, but Marmora's have a paler throat. Their iris is dark.
The Balearic Warbler is 20% smaller than the nominate form. It is also paler below, with a pinkish tinge.
These small passerine birds are found in open country with thorny bushes and heather. 3-5 eggs are laid in a nest in a bush. Like most "warblers", they are insectivorous.
This bird is named after the Italian naturalist Alberto della Marmora.

Sylvia undata
(Boddaert, 1783)

Sylvia undata - MHNT
The Dartford WarblerSylvia undata, is a typical warbler from the warmer parts of western Europe and northwestern Africa. Its breeding range lies west of a line from southern England to the heel of Italy (southern Apulia). The Dartford Warbler is usually resident all year in its breeding range, but there is some limited migration.

Description and systematics

The Dartford Warbler is a small (13 cm) passerine bird, distinguished by its long tail compared with that of other warblers. Its plumage comprises unobtrusive and muted tones, which blend in with the dry dead plants, old wood or sunny greyish wood found in its preferred habitats.
Like many typical warblers, the Dartford Warbler has distinct male and female plumages. The male has a grey back and head, reddish underparts, and a red eye. The reddish throat is spotted with white. The sides are a dull greyish tone, being more clear about the abdomen. In some populations males have bluish-grey or brownish-grey backs and heads. The female is paler below, especially on the throat, and a browner grey above. The female's throat also has white spots, although they are smaller and less marked than in the male. Juvenile birds are similar to females.
The song of the Dartford Warbler is a distinctive rattling warble.
The type locality of the Dartford Warbler is Provence in France. This species probably forms a superspecies with Tristram's Warbler and this in turn seems close to Marmora's Warbler and the Balearic Warbler. Altogether, this group of typical warblers bears a resemblance to the Wrentit, the only species of Sylviidae from the Americas. However the Wrentit is less closely related to the genus Sylvia than to the parrotbills. Its visual similarity to the Dartford Warbler group is an example of convergent evolution.

Ecology and status

This small "warbler" species breeds in heathlands, sometimes near coasts, with gorse bushes for nesting. Like its relatives, the Dartford Warbler is insectivorous, but will also take berries. The nest is built in low shrub, and 3-6 eggs are laid. It inhabits open fields with Jara and degraded scrub brush. Common in heather. In winter may be coming to urban solitary areas, but always it find shrubs in these areas. This shy warblers avoiding to the people. Nests in bushes with thorns and near the ground.
The species is naturally rare. The largest European populations of Sylvia undata focus on Iberian peninsula, and less in large part of France in Italy and southern England. In Africa can be found only in small areas in the north, being present as wintering in northern Morocco and northern Algeria. These warblers are mostly insectivore, feeding caterpillars, butterflys,beetles,
Spiders and larvas, etc.
Dartford Warblers are named for Dartford Heath in north west Kent, where the population became extinct in the early 20th century. They almost died out in the United Kingdom in the severe winter of 1962/1963 when the national population dropped to just 10 pairs. However, this species can recover well in good quality habitat, thanks to repeated nesting and a high survival rate for the young. Indeed they recovered in some areas of the UK, but numbers are once again on the decline in other regions of that country, as well as elsewhere.
Formerly classified as a 'Species of Least Concern' by the IUCN,it was suspected to be rarer than generally assumed. Following the investigation of the apparent decline this was confirmed, and the Dartford Warbler was consequently uplisted to Near Threatened status in 2008.

Sylvia communis
Latham, 1787, England
The Common WhitethroatSylvia communis, 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.
This is one of several Sylvia species that has distinct male and female plumages. Both sexes are mainly brown above and buff below, with chestnut fringes to the secondary remiges. The adult male has a grey head and a white throat. The female lacks the grey head, and the throat is duller. The Whitethroat's song is fast and scratchy, with a scolding tone.
This species was believed by some to be closely related to the Lesser Whitethroat, the species having evolved only during the end of the last ice age similar to the Willow Warbler and Chiffchaffs. But researchers learned soon that this is not correct, and now it is known that whitethroats are unreliable morphological markers for relationships inSylvia. Chestnut wing patches, like whitethroats, seem to be plesiomorphic, but indicate phylogeny better. Nonetheless, apart from the Whitethroat not being closely related to the Lesser Whitethroat group, little can be resolved as it seems a fairly basal taxon.(Helbig 2001, Jønsson & Fjeldså 2006)

Female with chicks
This is a bird of open country and cultivation, with bushes for nesting. The nest is built in low shrub or brambles, and 3-7 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries and other soft fruit.
