Brambling

The brambling, also called the cock o' the north and the mountain finch, is a small finch. Breeding-plumaged males are very distinctive, with a black head, dark upperparts, an orange breast and a white belly; females and younger birds are less distinct and more like some chaffinches. It is widespread in the breeding season throughout the forests of northern Europe and east across the Palearctic, migratory and often seen in very large flocks, wintering in southern Europe, North Africa, northern India, northern Pakistan, China and Japan (Wikipedia, general species account).

The eggs are laid at daily intervals, the clutch usually holding five to seven, each about 19.4 × 14.5 mm and weighing about 2.14 g, and the female incubates them for 11–12 days after the last is laid. SoIB 2023 lists it as a winter migrant of forest and plantation and an omnivore, without a priority category (Wikipedia, general species account; SoIB 2023).
