The downy woodpecker (Dryobates pubescens) is a species of woodpecker, the smallest in North America. Length ranges from 14 to 18 cm (5.5 to 7.1 in). Downy woodpeckers primarily live in forested areas throughout the United States and Canada, with the exception of deserts in the southwest and the northern tundra. The bird nests in tree cavities and feeds primarily on insects, although it supplements its diet with seeds and berries. The downy woodpecker is very similar in appearance to the hairy woodpecker, although they are not closely related.
The downy 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 pubescens and cited Catesby's book. The specific epithet pubescens is the Latin for "pubescent" or "downy". Linnaeus specified the type locality as America septentrionali (North America) but the locality is now restricted to South Carolina... Wikipedia →

With luck
About 10% of wildlife watchers report a Downy Woodpecker sighting in San Francisco on a given day, based on 12,099 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 375 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September and October
In those months about 20% of wildlife watchers report a Downy Woodpecker in San Francisco on a given day, against about 10% in November to August, the lowest months. Those are among San Francisco's driest months, with about 15 mm of rain a month against 110 mm in December.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Downy 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.
27th of 29
Of the 29 cities where we can rate Downy Woodpecker sightings, San Francisco ranks 27th at about 10%. The best odds are in Minneapolis [Saint Paul] (United States, about 70%), Montreal (Canada, about 70%) and Calgary (Canada, about 60%).
GBIF citizen-science records
It is estimated from how often the Downy Woodpecker is recorded against all the birds logged in San Francisco (12,099 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.
