Taxonomic note
Lyrurus tetrix (del Hoyo and Collar 2014) was previously placed in the genus Tetrao. Original note from Illustrated Checklists: Often placed with closely related L. mlokosiewiczi in genus Tetrao. Commonly hybridizes with Tetrao urogallus, and quite often with Lagopus lagopus, both hybrids even receiving vernacular names; also occasionally with Lagopus muta and Tetrastes bonasia. Geographical variation clinal: race tschusii often included in viridanus, but likely an intergrade; baikalensis sometimes subsumed within ussuriensis. Proposed race fedjuschini (from NW & N Ukraine) included in nominate. Review of subspecies required. Seven subspecies currently recognized.

Population justification: In Europe, the total population size is estimated at 2,430,000-3,750,000 mature individuals, with 1,210,000-1,880,000 breeding calling males (BirdLife International 2021), and comprises approximately 35% of the species' global range, so a very preliminary estimate of the global population size is between 6,940,000-10,700,000 mature individuals, although further validation of this estimate is desirable. The European trend for this species is not known (BirdLife International 2021), although its population in Fennoscandia has fluctuated (PECBMS 2023). The population has suffered major declines and range contractions over much of its range owing to afforestation of heathland, increased cultivation and planting of coniferous monocultures, and also suffers locally from over-hunting (del Hoyo et al. 1994). This species is considered to have a medium dependency on forest habitat, which is estimated to be declining at a rate of 7.1% over the past three generations within its mapped range (Global Forest Watch 2024). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a slow decline over the same time frame.
