This small but long tailed, large headed warbler, is a resident of the Balearic Islands in the western Mediterranean where it is common, although is not present on the island of Menorca.

The adult male in breeding plumage is predominantly grey above and pale grey below, with a blue grey head and a pronounced red orbital ring surrounding a dark orange iris. There is a darker grey area forming a mask from the base of the top of the beak extending around the top of the eye. The flight feathers are a dark grey almost black with lighter edges and the bastard wing (alula) is black, fringed white. The long tail is black, fringed grey with white tips. Chin and throat are a pale grey morphing to an almost white breast, belly and vent. The flanks are a dirty white or light buff colour. The bill is a pinky orange with a black tip, particularly across the upper mandible and the legs are pinkish light brown. In non breeding plumage the upperparts and wing coverts of the adult male have more of a brownish hue and the dark face mask is less obvious. The underparts are more buff coloured than white whilst the area around the throat loses its grey colouration and becomes white. The plumage of the breeding female is similar to the non breeding plumage of the male but lacks the blue hue and overall is more of a brownish shade. Non breeding females have brown upperparts and white underparts.

The call is a short medium pitched ‘chru – chru’ sound repeated often whilst the song is typically a series of warbles generally ending with a multi pitched trilling.

The Balearic warbler survives mainly on a diet of insects and spiders which it takes during ground foraging of from branches and leaves on low scrub and bushes. It will also take flies in flight and seasonally will supplement its diet with fruits.
This bird is monotypic and endemic to the Balearic archipelago off the east coast of the Iberian Peninsula, which includes the islands of Mallorca, Ibiza, Cabrera and Formentera. It is not found on the island of Menorca, the second largest island of the group.

Whilst mainly occupying areas of dry scrubland, pine forests and juniper trees are also favoured by this small, solitary, but pretty bird. Whilst its markings are similar in part to the Marmora’s Warbler and even the Dartford Warbler, it is widespread throughout its range and its blue grey head, orange iris and bold red orbital ring aids positive identification. It can often be seen singing at the top of a bush or tree top. The bird is resident within its range and is a common site in the Boquer Valley in the north of Mallorca.
At the start of the breeding season which runs from March through to June both parents construct a cup shaped nest lined with fine grasses and hair which is located in low lying scrub approximately half a metre above ground level. Two broods, each of between 2 – 4 eggs, are produced annually during the season and are incubated by both parents for up to two weeks. Fledging occurs some twelve days later.
The lifespan of the Balearic Warbler is up to five years.
Wood warblers are tuneful breeding visitors, arriving in British woodlands from April onwards. Well hidden in their preferred tree-filled landscapes, their bright yellow breast makes them easily distinguishable from other similar warbler species.
The diminutive Willow warbler is a small bird from the Leaf Warbler family Phylloscopidae which contains 80 species. Willow warblers are primarily insectivorous and are energetic, constantly moving birds that dart their tree and hedgerow habitats. They possess soft and subtle green plumage with a pale green-grey back, wings and tail with a pale grey stomach that has a slight yellow tinge.
Whitethroats are active warblers that can be seen and heard in hedgerows around Britain during spring and summer months, as they raise their young and busily forage for insects. Each autumn, they depart for wintering grounds in sub-Saharan Africa, returning in April to breed once more.
Widespread and common breeding visitors to the UK, sedge warblers arrive on marshlands and reedbeds in April, and spend up to 6 months on British soil (or wetlands, to be more accurate), raising their young, before preparing for lengthy migrations to wintering grounds in sub-Saharan Africa each autumn.
Not to be confused with the Great Reed Warbler, this relatively nondescript, solitary little bird is an annual visitor to the UK from sub-Saharan Africa, arriving in mid April and departing early in October.
A well-camouflaged visitor to grasslands and reedbeds, grasshopper warblers arrive in Britain to breed each spring. You may stand a better chance of hearing one than actually getting a sighting, as their secretive nature of creeping through vegetation makes them almost impossible to spot.
This mainly plain, solitary, short billed, stocky little warbler is widespread throughout Europe and a long distance migrant to Africa, crossing the Sahara Desert without pause.
Mainly confined to lowland heaths in southern England, the Dartford warbler is an elusive little resident breeder with distinctive plumage and physical characteristics.
Until recently this small, solitary, old world leaf warbler was classified as being a member of the family Sylviidae, but following extensive research and reclassification, now falls within the family of Phylloscopidae.
Named after the 18th century Italian zoologist and Jesuit priest, Francisco Cetti this small plain looking bush warbler is frequently heard but difficult to spot.
Within its range and to differentiate it from other similar species, it is often referred to as an Eurasian Blackcap. This sexually dichromatic, stocky little warbler, is a member of the genus Sylvia and is sometimes nicknamed the Northern Nightingale due to its beautiful and frequent song.
