Taxonomic note
Picoides tridactylus and P. funebris (del Hoyo and Collar 2014) were previously lumped as P. tridactylus following AOU (2003). P. tridactylus (del Hoyo and Collar 2014) was previously split into P. tridactylus and P. dorsalis following AOU (2003), and prior to that all three taxa were lumped as P. tridactylus following Sibley and Monroe (1990, 1993).

Distribution and population
The species has a large range across boreal Eurasia, with isolated resident populations in mountains to the south, including the Alps, Altai, and Tien Shan.

Ecology
The species inhabits mature conifer forests, particularly spruce Picea spp., and is somewhat irruptive, being found commonly where disturbance such as fire has caused local outbreaks of insects (Winkler et al. 1995).

Threats
Large-scale commercial logging and modern forestry management practices, including fire suppression and removal of dead or insect-infested trees, have led to declines of American Three-toed Woodpecker P. dorsalis (Hutto 1995., Leonard 2001), and are also likely to have led to declines of this species.
