Teterev

Teterev is a genus of large birds in the grouse family, Tetraonidae. They are native to temperate and boreal regions of Eurasia. The genus currently contains two species: the Western Capercaillie (Tetrao urogallus) and the Black Grouse (Tetrao tetrix). While sometimes considered separate genera, recent genetic studies have placed them together.

The Western Capercaillie is the largest member of the grouse family, with males significantly larger and heavier than females. They inhabit mature coniferous forests, where they feed on pine needles, buds, and berries. Their displays, known as leks, are a prominent feature of their breeding behavior, with males gathering in specific areas to perform elaborate courtship rituals.

The Black Grouse is smaller and more widespread than the Western Capercaillie. It prefers open woodland, moorland, and heathland habitats. Like the capercaillie, black grouse also engage in lekking behavior during the breeding season, with males strutting and displaying their iridescent plumage to attract females. Their diet consists of leaves, buds, insects, and seeds.

Both Teterev species are important game birds and their populations can be influenced by habitat availability and hunting pressure. Conservation efforts are in place in various regions to protect their habitats and ensure the long-term survival of these distinctive birds. Their scientific name, Teterev, is derived from the Russian word for grouse.
