Distribution
Breeds in southern England, the Channel Islands and southernmost Wales, in western France and on the Mediterranean coast and throughout Iberia. Also breeds on Menorca, on Corsica and Sardinia, southern Italy and north-east Sicily and in coastal North Africa in Morocco, Algeria, and Tunisia.
Britain lies on the northern edge of this species' range and it occurs mainly in southern England with the bulk of the population found from Devon to Sussex and Surrey with small numbers in Cornwall and on the Isle of Wight. With global warming, the species has increased and spread north in recent decades, and now breeds in coastal heaths in south Wales, Essex, Suffolk and Norfolk; extralimital breeding has also occurred in north Wales and Staffordshire.[2]
Vagrants have been recorded in Ireland, Scotland, Belgium and the Netherlands, Germany and Sweden, and east to Greece and the former Yugoslavia, and also in Libya.
Taxonomy
This is a polytypic species[1] consisting of 3 subspecies.
Subspecies
- C. u. dartfordiensis: has a dark brown mantle
- C. u. undata: has a slate-grey mantle
- C. u. toni: the palest race, is greyish-brown above and paler and duller below
Habitat
In north of range found on open heathland with abundant gorse (Ulex sp.) and heather (Calluna vulgaris) to provide cover, further south in dense thorny scrub and maquis, sometimes in open pinewoods. In Spain it is mainly present in areas with low scrub (no taller than 1 metre) without trees (or with only few). Slopes with Gum Cistus (Cistus ladanifer) are a favourite.
Behaviour
Diet
The diet consists mostly of insects and spiders, with the addition of berries outside of the breeding season.
Breeding
It nests in low vegetation. The clutch consists of 3-6 eggs.
Movements
Mainly resident, but some birds, mainly juveniles, wander in winter and range expands in the south of range, especially on Balearics, Malta, Sicily, and in North Africa.
Vocalisation
Song: a scratchy rattling warble. Call has been described as a sort of lowish buzz "ddzzz".
