The hairy woodpecker (Leuconotopicus villosus) is a medium-sized woodpecker that is found over a large area of North America.

The species was previously placed in the genus Dryobates.
The hairy woodpecker was described and illustrated with a hand-coloured plate by the English naturalist Mark Catesby in his The Natural History of Carolina, Florida and the Bahama Islands which was published between 1729 and 1732. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he included the downy woodpecker, coined the binomial name Picus villosus and cited Catesby's book. 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 →

With luck
About 10% of wildlife watchers report a Hairy Woodpecker sighting in Boston on a given day, based on 3,991 verified sightings from GBIF citizen-science data. It is the 61st most-seen of the 283 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August to May
In those months about 10% of wildlife watchers report a Hairy Woodpecker in Boston on a given day, against under 5% in June and July, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Hairy Woodpecker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Hairy Woodpecker is recorded against all the birds logged in Boston (3,991 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.
