Rare
Under 5% of wildlife watchers report a Mountain Bluebird sighting in Pacific Rim National Park Reserve on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 175th most-seen of the 187 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

GBIF citizen-science records
It is estimated from how often the Mountain Bluebird is recorded against all the birds logged in Pacific Rim National Park Reserve (10 verified sightings from 2019 to 2026), 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.
