The California scrub jay (Aphelocoma californica) is a species of scrub jay native to western North America. It ranges from southern British Columbia throughout California and western Nevada near Reno to west of the Sierra Nevada. The California scrub jay was once lumped with Woodhouse's scrub jay and collectively called the western scrub jay. IUCN and the Handbook of the Birds of the World maintain this lumped taxon. The group was also lumped with the island scrub jay and the Florida scrub jay; the taxon was then called simply scrub jay. The California scrub jay is nonmigratory and can be found in urban areas, where it can become tame and will come to bird feeders. While many refer to scrub jays as "blue jays", the blue jay is a different species of bird entirely.
The generic name, Aphelocoma, derives from Latinized Ancient Greek apheles- (from ἀφελής-) "simple" + Latin coma (from Greek kome κόμη) "hair", in reference to the lack of striped or banded feathers in this genus, compared to other jays. The species name, californica, is Latin for "from California".
The California scrub jay is a medium-sized bird, approximately 27–31 cm (11–12 in) in length... Wikipedia →

Rare
Under 5% of wildlife watchers report a California Scrub-Jay sighting in Vancouver on a given day, based on 318 verified sightings from GBIF citizen-science data. It is the 174th 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 California Scrub-Jay in Vancouver on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most California Scrub-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.
7th of 7
Of the 7 cities where we can rate California Scrub-Jay sightings, Vancouver ranks 7th at under 5%. The best odds are in Sacramento (United States, about 90%), Portland (United States, about 50%) and San Francisco (United States, about 40%).
Same family: Corvidae
The closest relatives of the California Scrub-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 California Scrub-Jay is recorded against all the birds logged in Vancouver (318 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.
