Descriptive notes.
12 cm, 11g, wingspan 15-19 cm. Rather small, quite slim, and elegant warbler, with rather short bill. Male blue-grey above, dark pink-chestnut belw, with white moustachial stripe. Female grey-brown above, buff-white below.
Sexes dissimilar, no seasonal variation but rare pale birds occurin nominate, suggesting Menetries's Warbler.
Habitat. Breeds in Mediterranean region, in dry, warm summer climate, from sea-level to 2000 m in Haut Atlas of Morocco. In habitat spectrum of Mediterranean Sylvia warblers, differs most from Marmora's Warbler and Dartford Warbler which normally avoid trees, and least from Sardinian Warbler which is even more arboreal.
Lives in dense, xerophytic, often prickly scrub on sunny hillsides, often clad mainly in holm Oak and kermes oak, but even down to lowest and poorest thorn scrub.
Food and Feeding.
Chiefly adult and larval insects, also fruit in late summer and autumn. Feeds in scrub, also in foliage of olive, oaks, and other trees.
Breeding.
Early Apr to late June in Southern Europe, early May to mid Jun in Algeria. Nest site, in low bushes, or occasionally low trees 30-150 cm above ground.
Nest, deep, well-built cup of grass stems and leaves, also leaves and stalks of other herbs, with some roots and plant down, almost always with cobwebs in outer layers. Lined with finer grasses, herbs, rootlets, and hair.
3-4 eggs, sub-elliptical, smooth and glossy, whitish, sometimes tinted green or olive, or buff, markings often gathered at large end. Incubation 11-12 days, by both sexes, in roughly equal spelss.
Movements.
Western race, nominate, and eastern race albistriata wholly migratory, north-west African race inornata mostly migratory, all populations wintering in Africa, chiefly along southern edge of Sahara.
Status and Conservation.
Not globally threatened.
Israel.
In Israel two subspecies S. c. albistiata scarce passage migrant, mainly in spring, and S. c. cantillans apparently accidental.
