Capercaillie

Male capercaillies perform spectacular communal displays in spring, gathering in woodland clearings to parade around, fanning their magnificent tail feathers and making strange gulping and clicking sounds as they compete for the attention of females.

Habitats

Ynghylch

The capercaillie is a huge gamebird, the size of a turkey, that lives in the forests of Scotland. Loss of its woodland habitat led to the capercaillie becoming extinct in the UK in the mid-18th century, but birds were reintroduced from Sweden almost a century later. They are now restricted to pine forests in the north of Scotland, where they feed on berries and the shoots and buds of conifer trees.

Sut i'w hadnabod

Male capercaillie are huge birds, with glossy black bodies, tinged green on the breast, and brown wings. They have a strong, yellow bill and a red mark above the eye. Females are smaller and largely brown with darker barring. They are similar to female black grouse, but have a patch of bright, unbarred orange-brown on the throat and upper breast.

Dosbarthiad

In the UK, capercaillie are found only in the pinewoods of northern Scotland.
