The hairy woodpecker (Leuconotopicus villosus) is a medium-sized woodpecker that is found over a large area of North America. It is approximately 250 mm (9.8 in) in length with a 380 mm (15 in) wingspan. With an estimated population in 2020 of almost nine million individuals, the hairy woodpecker is listed by the IUCN as a species of least concern. 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 →

Possible
About 20% of wildlife watchers report a Hairy Woodpecker sighting in Chicago on a given day, based on 11,948 verified sightings from GBIF citizen-science data. It is the 47th most-seen of the 314 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September and December
In those months about 30% of wildlife watchers report a Hairy Woodpecker in Chicago on a given day, against about 10% in May to 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.
8th of 24
Of the 24 cities where we can rate Hairy Woodpecker sightings, Chicago ranks 8th at about 20%. The best odds are in Minneapolis [Saint Paul] (United States, about 40%), Montreal (Canada, about 30%) and Calgary (Canada, about 30%).
Same family: Picidae
The closest relatives of the Hairy Woodpecker that you can see in Chicago (family Picidae, Woodpeckers) are Downy Woodpecker (about 60%), Northern Flicker (about 40%) and Red-bellied Woodpecker (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hairy Woodpecker is recorded against all the birds logged in Chicago (11,948 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.
