15-17 cm, 18-24 g, wingspan 21-28 cm. Medium-sized to rather large bunting, seemingly large headed and thick-necked (male), with fairly lengthy form and distinctive voice. Breeding male instantly recognized by black head and bib and white collar, shared only by Pallas's Reed Bunting. Paler eastern birds, rare small individuals, and occasional aberrant head plumage present serious pitfalls. Has habit of nervously spreading tail. Sexes dissimilar, marked seasonal variation in male. Habitat. Most widespread in range of west Palearctic breeding Emmberizidae, inhabiting oceanic islands and peninsulas, and continental plains from arctic through boreal, temperate, and Mediterranean to steppe and even desert climatic zones. Yet within this vast range, choice of occupied sites is ecologically restricted to particular types of dense and prolific fairly low vegetation, mainly associated with intense soil moisture. Avoids both closed forest and typical open country, as well as bare, rocky, or frozen surfaces, steep or broken ground, and areas of immediate human disturbance or settlement. Food and Feeding. seeds and other plant material, invertebrates in breeding season, and also opportunistically during remainder of year. Takes plant and animal material on ground among sedges, rushes, reeds, etc., in pasture and marshy grasslands, and also low in waterside bushes and trees willow, alder, or on stems of reed. Outside breeding season, more often on ground in open countryside and cultivated fields, weedy areas, woodland clearings, uplands, etc., well away from water, often in flocks with other seed-eaters. Breeding. May-Jul in England, mid May to late Jun in Finland, Apr-Jul in Eastern Germany. Nest site, usually well hidden on ground or on sedge tussocks, heaps of dead rushes, reeds, etc., by water, also up to 4 m above ground. Nest, foundation of stems and blades of sedges, grasses, and other waterside plants, occasionally small twigs, lined with finer plant material, moss, rootlets, and sometimes hair or feathers. 4-5 eggs, sub-elliptical, smooth and slightly glossy. Very pale purplish, lilac-grey, or olive-brown, rarely buffish or greenish, with scrawls, spots, and blotches of purplish-brownish-black irregularly distributed over whole surface, or concentrated at either end. Incubation, 12-15 days, by female only. Movements Northern group schoeniclus sedentary to migratory, southern group pyrrhuloides of races chiefly sedentary. Winters in areas with little or no snow cover making mid-winter flights if snowfall persists. In Europe, nominate migratory in N-E, increasingly sedentary towards S-W, migrants head between SSW and W. Status and Conservation. Not globally threatened. Apparently no general trends, but local and regional changes, attributed to various causes. Israel. In Israel four subspecies E. s. schoeniclus uncommon migrant and winter visitor. E. s. intermediascarce but locally uncommon migrant and winter visitor, mainly in north and west. E. s. ukrainae a scarce winter visitor, chiefly in northeastern parts. E. s. pallidior individuals resembling this form recorded rarely.
