The black grouse (Lyrurus tetrix), also known as northern black grouse, Eurasian black grouse, blackgame or blackcock, is a large bird in the grouse tribe. It is a sedentary species, spanning across the Palearctic in moorland and steppe habitat when breeding, often near wooded areas. They will spend the winter perched in dense forests, feeding almost exclusively on the needles of conifers. The black grouse is one of two species of grouse in the genus Lyrurus, the other being the lesser-known Caucasian grouse.
The female is greyish-brown and has a cackling or warbling call. She takes all responsibility for nesting and caring for the chicks, as typical with most galliforms. The black grouse's genome was sequenced in 2014. The black grouse was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Tetrao tetrix. Both Tetrao and tetrix come from Ancient Greek words referring to some form of game bird. The black grouse is now placed in the genus Lyrurus that was introduced in 1832 by the English naturalist William Swainson.

With luck
About 10% of wildlife watchers report a Eurasian Black Grouse sighting in Vanoise National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 67th most-seen of the 81 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
October
In that month about 30% of wildlife watchers report a Eurasian Black Grouse in Vanoise National Park on a given day, against under 5% in January–March and June–September, the lowest months. November has too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Eurasian Black Grouse sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Eurasian Black Grouse sightings, Vanoise National Park ranks 3rd at about 10%. The best odds are in Cairngorms National Park (United Kingdom, about 20%) and Hohe Tauern National Park (Austria, about 10%).
GBIF citizen-science records
It is estimated from how often the Eurasian Black Grouse is recorded against all the birds logged in Vanoise National Park (15 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
