Fringilla montifringilla
Habitat
Breeds in the forests of northern Europe and east across the Palearctic
Clutch size
Usually 5–7 eggs laid at daily intervals, light blue to dark olive-brown with pink to rusty-red spots
Incubation period
11–12 days, by the female
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 (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 (Wikipedia, general species account).
