Plumage plain dull brown above and pale buff below, lacks any prominent character but dark eye emphasized by short pale buff to greyish fore-supercilium and eye-ring. Sexes similar, little seasonal variation. Habitat. Breeds in middle and upper middle latitudes of west Palearctic in continental and marginally oceanic, mainly temperate climate. Preference for shrubby clusters of green alder, lower levels in shady broad-leaved scrub often moist and by water, although sometimes in copses of warm dry soils. Avoids pure coniferous stands, dense plantations, and towns, and occurs only occasionally in gardens and parks. Food and Feeding. Chiefly insects in breeding season, mainly plant material at other times. Searches vegetation to pick insects from foliage and twigs, sometimes hovering or sallying out to catch flying insects. Breeding. Mer-Jul in N-W Europe, Apr to mid Jul in W Germany, end My to 2nd half of Jul in Finland. Nest site, in low tree or bush or tall herbs. Nest, substantial cup, loosely constructed on outside and underneath, of grass and herb stems and leaves, with some twigs and roots, up to 30 cm long, plus a little plant down and cobwebs, lined with finer grasses and rootlets and long hair. 4-5 eggs, sub-elliptical smooth and glossy, very variable, from white to buff, pink or green tinted, spotted and blotched buff, brown, olive, red-brown, grey, and purple, larger pale blotches often with dark center, other spots with blurred edges. Incubation, 11-12 dayas, by both sexes, but male only during daylight hours and then less than female. Movements. All populations migratory, wintering extensively in Africa. Differentiation of races sometimes uncertain, and considerable overlapping occurs in winter range. Status and Conservation. Not globally threatened. Estimated 10-14.000.000 pairs in Urope. Israel.
