It is typically found within foothills, especially where pinyon pines (Pinus edulis and Pinus monophylla) occur.
The pinyon jay is a bluish-grey coloured bird with deeper head colouring and whitish throat with black bill, legs and feet. Roughly intermediate between the blue jay and the Eurasian jay in size, its overall proportions are similar to Clark's nutcracker (Nucifraga columbiana) and this can be seen as convergent evolution, as both birds fill similar ecological niches. They were once known as "blue crows".
The pinyon jay was first collected, recorded, and first described as a species from a specimen shot along the Marias River in what is now northern Montana during the Prince Maximilian of Wied-Neuwied expedition to the interior of North America in 1833.

Rare
Under 5% of wildlife watchers report a Pinyon Jay sighting in Vancouver on a given day, based on 229 verified sightings from GBIF citizen-science data. It is the 185th most-seen of the 252 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Pinyon Jay in Vancouver on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Pinyon Jay sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Vancouver, in our data
Vancouver is the only city on Wallace's Line with enough records to rate Pinyon Jay sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Corvidae
The closest relatives of the Pinyon Jay that you can see in Vancouver (family Corvidae, Crows, Jays, and Magpies) are American Crow (about 90%), Common Raven (about 20%) and Steller's Jay (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pinyon Jay is recorded against all the birds logged in Vancouver (229 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.
