Black Grouse (Lyrurus tetrix) lives in moorland heath across Europe and Asia. It feeds on heather and insects. Its conservation status is Least Concern.
Fascinating facts about the Black Grouse
- The black grouse's tail feathers curl outward, forming a lyre-shaped silhouette that gave the genus its name Lyrurus. This distinctive shape is created by the bird's long outer rectrices, which are especially prominent in males. The same lyre-like tail is shared with its close relative, the Caucasian grouse, highlighting a unique trait within the genus.
- Each spring at dawn, male black grouse gather on open ground called a lek, fanning their lyre-shaped tails and inflating their necks to attract females. Their display is accompanied by a long, bubbling coo or murmur that signals territory and vigor. In western Europe these leks seldom hold more than 40 birds, whereas in Russia gatherings can swell to 150 and occasionally reach up to 200 individuals, making the eastern displays far larger.
- The black grouse's entire genome was sequenced in 2014, providing a comprehensive genetic blueprint for the species. This achievement places the bird among the few grouse whose DNA has been fully mapped, offering new tools for studying its biology and conservation. As one of only two species in the genus Lyrurus, alongside the lesser-known Caucasian grouse, the genomic data help clarify evolutionary relationships within the group.
- The black grouse numbers between 15 million and 40 million individuals worldwide, a size that keeps it out of the vulnerable category despite ongoing losses in parts of its range. Its overall decline is slow, and the IUCN notes the species is not considered vulnerable globally because of this large, slowly decreasing population. Habitat loss and disturbance are the main pressures driving regional drops, but they have not yet pushed the global stock into danger.
- In winter the black grouse retreats to dense coniferous forests, where it roosts in large flocks and feeds almost exclusively on the needles of trees such as Scots pine and Siberian larch. This seasonal habit shifts its diet away from the berries and shoots it eats in summer to the leaves and buds of conifers, allowing it to survive the colder months when other food sources are scarce.

About the Black Grouse
In the misty dawn of the northern moors, the black grouse emerges as a mysterious figure, its sleek black plumage glistening with dew as it moves with purposeful intent, its powerful legs striding effortlessly across the heather-covered landscape. With a flick of its lyre-shaped tail, the male bird announces its presence, a charismatic display of courtship and territoriality that resonates through the stillness, a primal call that echoes across the wild expanse. As it dances, its feathers rustling softly, the black grouse embodies the untamed spirit of the wilderness, a symbol of resilience and beauty in the harsh yet majestic landscape it calls home.
