Lewis's woodpecker (Melanerpes lewis) is a large North American species of woodpecker which ornithologist Alexander Wilson named after Meriwether Lewis. Lewis was one of the explorers who surveyed the areas bought by the United States of America as part of the Louisiana Purchase and first described this species of bird.
Lewis's woodpecker was described and illustrated in 1811 by the American ornithologist Alexander Wilson in his American Ornithology; or, the Natural History of the Birds of the United States. Wilson based his description on some bird skins that had been collected on an expedition across the western portion of the United States led by Meriwether Lewis and William Clark in 1803–1806. Wilson coined the English name "Lewis's woodpecker" and the binomial name Picus torquatus. Unfortunately, the specific epithet was preoccupied by the ringed woodpecker, Celeus torquatus (Boddaert, 1783), so in 1849, the English zoologist George Robert Gray coined a new name, Picus lewis. The type locality is Montana. Lewis's woodpecker is now placed in the genus Melanerpes that was erected by the English ornithologist William Swainson in 1832. The species is monotypic: no subspecies... Wikipedia →

Rare
Under 5% of wildlife watchers report a Lewis's Woodpecker sighting in Calgary on a given day, based on 266 verified sightings from GBIF citizen-science data. It is the 150th most-seen of the 259 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report a Lewis's Woodpecker in Calgary on a given day, against under 5% in June to April, the lowest months. That is one of Calgary's wettest months, with about 75 mm of rain against 15 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Lewis's 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.
2nd of 11
Of the 11 cities where we can rate Lewis's Woodpecker sightings, Calgary ranks 2nd at under 5%. The best odds are in Phoenix (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Lewis's Woodpecker is recorded against all the birds logged in Calgary (266 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.
