The Eurasian three-toed woodpecker (Picoides tridactylus) is a medium-sized woodpecker that is found from northern Europe across northern Asia to Japan. The Eurasian three-toed woodpecker was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He coined the binomial name Picus tridactylus. The type locality is Sweden. The specific epithet is from the Ancient Greek tridaktulos meaning "three-toed" (tri- is "three-" and daktulos is toe). The species is now placed in the genus Picoides that was introduced by the French naturalist Bernard Germain de Lacépède in 1799. The Eurasian three-toed woodpecker was formerly considered conspecific with the American three-toed woodpecker (Picoides dorsalis).

Rare
Under 5% of wildlife watchers report a Eurasian Three-toed Woodpecker sighting in Saint Petersburg on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 143rd most-seen of the 167 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Eurasian Three-toed Woodpecker in Saint Petersburg on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Eurasian Three-toed Woodpecker is recorded against all the birds logged in Saint Petersburg (10 verified sightings), 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.
