Description

The fieldfare is easily recognisable with its slate-grey head, nape and rump, dark brown back, blackish tail and boldly speckled breast. In flight, its white under wing-coverts and axillaries are conspicuous. The harsh flight call "tsak tsak" is also distinctive. The forehead and crown of the male are bluish-grey and each feather has a central brownish-black band. The lores and under-eye regions are black and there are faint, pale streaks above the eyes. The ear coverts, nape, hind neck and rump are bluish-grey, usually with a white streak near the shaft of each rump feather. The scapulars and mantle feathers are dark chestnut-brown with dark central streaks and pale tips. There are fourteen tail feathers each with a pointed tip, the outer two slightly shorter than the others giving a rounded tail. They are brownish-black, with inconspicuous darker bars visible in some lights. The outer edge of each tail feather is fringed with grey near the base and the outer pair of feathers have a narrow white border on the inner edge. The chin, throat and upper breast are creamy-buff with bold streaks and speckles of brownish-black. The lower breast is creamy-white with a diminishing buff tinge and fewer speckles and the belly is similarly creamy-white, with the speckles restricted to the uppermost parts. The

are brownish-black with the leading edge fringed grey and the inner edge of the outer feathers grey near the base whereas the inner feathers are fringed with brown near the base. The secondaries are similar but fringed with chestnut-brown on the leading edge. The upper wing-coverts are brownish-black and similar to the outer primaries in their margin colouration. The axillaries and under wing-coverts are white and the under tail-coverts have dark greyish-brown bases and margins and white centres and tips. The beak is strong, with a slight curve and a notch near the tip. It is orange-yellow in winter, with the upper mandible somewhat brownish and both mandible tips brownish-black. In the summer both mandibles of the male's beak are yellow. The irises are dark brown and the legs and feet are brown. The average adult length is , the winglength is and the tarsal length . Wingspan ranges from 39 to 42 cm and weight ranges from 80 to 140 g. The female is very similar to the male but the upper parts are somewhat more brownish and the feathers on the crown have narrower black central stripes. The throat and breast are paler with fewer, smaller markings. The beak is similar to the male's winter beak. The juvenile are a duller colour than the adults with pale coloured streaks on the feathers that have dark streaks in the adult. The young assume their adult plumage after their first moult in the autumn. The call is mostly uttered in flight and is a harsh "tsak tsak tsuk". The same sound, but softer, is made more conversationally when individuals gather in trees. When angry or alarmed they emit various warning sounds reminiscent of the

. In the winter, groups of fieldfares are chiefly found in open country, agricultural land, orchards and open woodland. They are nomadic, wandering wherever there is an abundance of berries and insects. Later in the year they move on to pastureland and cultivated fields.


Migration

Migration southwards from the breeding range starts in October but the bulk of birds arrive in the United Kingdom in November. Some of these are still on passage and carry on into continental Europe but others remain. The passage-migrants return in April and they and the resident migrants depart from the United Kingdom mostly by early May.

Breeding

The breeding season starts in May in Poland but further north in Scandinavia may not start until early July. The female fieldfare builds a cup-shaped nest with no attempt at concealment. The location is often in woodland but may be in a hedgerow, garden, among rocks, in a pile of logs, in a hut or on the ground. Fieldfares usually nest in close proximity to others of the same species. The adults will defend the nest aggressively and nesting gregariously may offer protection from predators. The nest is built of dried grasses and weeds with a few twigs and a little moss, with a lining of mud and an inner lining of fine grasses. There are usually five to six eggs in a clutch, but occasionally three, four, seven or eight eggs are laid. The eggs vary in size from and are variable in colour. Many are pale blue speckled with fine brown dots and resemble those of the common blackbird. Others are bright blue, with or without larger red-brown splotches. Incubation starts before all the eggs are laid and lasts for thirteen to fourteen days. The female does all or most of the incubation. The chicks are

and both parents bring food to them. They are usually ready to leave the nest after fourteen to sixteen days and there may be two broods in the season, especially in the southern parts of the breeding range.


Status and conservation

The fieldfare has an extensive range, estimated at 10 million square kilometres (3.8 million square miles), and a large population, including an estimated forty two to seventy two million individuals in Europe. There are thought to be up to twenty million individuals in Russia and the global population is estimated to be between forty-four and ninety-six million individuals. The population size appears to be stable and the bird is not believed to approach the thresholds for the population decline criteria of the
