Capercaillies nest on the ground often at the base of a tree. They may occasionally use old nests placed above the ground. The nest is a shallow depression in the ground which the female lines with grass, pine needles, and twigs.
Capercaillies lay 6-9 eggs which the female incubates alone for 26 days. Chicks are precocial but are kept warm by their mother during the first week. They can fly at 2-3 weeks.
Capercaillies eat mainly plant matter such as pine needles, shoots, leaves and berries. Chicks will also feed on insects, caterpillars, beetles, and ants.
Capercaillies can be seen all year round in Scottish native pinewoods.

Capercaillies are on of the UK’s rarest birds. They became extinct in the 1700s and were reintroduced in the 1830s. But since the 1970s their population has severely decreased again due to loss of habitat.
