Bestimmung

The brambling is similar in size and shape to a common chaffinch. Breeding-plumaged male bramblings are very distinctive, with a black head, dark upperparts, orange breast and white belly. Females and younger birds are less distinct, and more similar in appearance to some chaffinches. In all plumages, however, bramblings differs from chaffinches in a number of features:<p>An additional difference for all plumages except breeding-plumaged males is the bill colour - yellow in the brambling, dull pinkish in the common chaffinch (breeding-plumaged male bramblings have black bills, common chaffinches in the corresponding plumage have grey bills).<p>Measurements:

Taxonomie

In 1758 Linnaeus included the species in the 10th edition of his Systema Naturae under its current binomial name, Fringilla montifringilla. Montifringilla is from Latin mons, montis mountain and fringilla finch. The English name "bramlyng" (Bram “loud” + lyng “lung”) was used in 1544 by the English naturalist William Turner but later in the 16th century the current spelling "brambling" was used. The etymology of the name is uncertain as the bird is not associated with the bramble or common blackberry Rubus fruticosus.

Verbreitung und Lebensraum

This bird is widespread, in the breeding season, throughout the forests of northern Europe and east across the Palearctic. It is migratory, wintering in southern Europe, North Africa, northern India, northern Pakistan, China, and Japan. It frequently strays into Alaska during migration and there are scattered records across the northern United States and southern Canada. The global population of bramblings is about 100 to 200 million, with a decreasing trend.<p>Open coniferous or birch woodland is favoured for breeding.<p>This species is almost entirely migratory. In Europe, it forms large flocks in the winter, sometimes with thousands or even millions of birds in a single flock. Such large gatherings occur especially if beech mast is abundant. Bramblings do not require beech mast in the winter, but winter flocks of bramblings will move until they find it. This may be an adaptation to avoid competition with the common chaffinch.

Verhalten

Bramblings first breed when they are one year old. The nest is usually placed high in a tree against the trunk. It is built by the female and consists of an outer layer which may contain lichen, grass, heather, cobwebs and strips of bark from birch or juniper trees. It is lined with feathers, soft grass and hair. The eggs are laid at daily intervals. The clutch usually contains 5-7 eggs. They range from light blue to dark olive-brown and have pink to rusty red spots and blotches. On average they measure 19.4 mm × 14.5 mm (0.76 in × 0.57 in) and have a calculated weight of 2.14 g (0.075 oz). Starting after the last egg has been laid, they are incubated by the female and hatch after 11-12 days. The young are fed and cared for by both parents and fledge after 13-14 days. Often only one brood is raised each year but two broods can be raised in northwest Russia.<p>The nests can be predated by the carrion crow (Corvus corone) and the Siberian jay (Perisoreus infaustus). The nest are often parasitized by the common cuckoo (Cuculus canorus).<p>Bramblings mostly eat seeds in winter, but insects in summer.
