The specific epithet villosus is the Latin word for "hairy". Linnaeus specified the type locality as America septentrionali (North America), with specific mention of Raccoon, New Jersey. The hairy woodpecker was formerly usually placed in either Dendrocopos or Picoides but a molecular phylogenetic study published in 2015 found that these genera... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Hairy Woodpecker is recorded against all the birds logged in Portland (3,508 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.
