About

The Hazel grouse is the smallest of the forest grouse in the Carpathians. It lives in mixed and coniferous forests with dense underbrush, spruce, alder, hazel, and berry bushes, often near streams and on overgrown clearings. It occurs in all Carpathian countries, from the foothills to the upper limit of the forest.

The bird is the size of a pigeon, mottled, grayish-brown with reddish and white spots, and has a small crest. The male has a black throat bordered with white, while the female has a light throat. The Hazel grouse stays on the ground, but when in danger, it takes off with a loud flutter and perches on a branch closer to the trunk, where it is almost invisible.

Hazel grouse live in pairs and maintain their territory all year round. Their voice is a thin prolonged whistle, which can easily be mistaken for a bird's trilling. In summer, the birds eat berries, seeds, buds, and insects; chicks primarily need insects. In winter, they feed on buds and catkins of alder, birch, and hazel, and to escape the cold, they roost buried in the snow.

The female makes a nest on the ground, under a bush or a fallen trunk, and incubates the chicks, which can run after her just a few days after hatching.

The Hazel grouse is listed in the Red Book of Ukraine as a vulnerable species, and hunting it is prohibited.
