Abstract: A quantitative analysis of specimens is used to describe each subspecies and intergrade of Steller’s Jay known from British Columbia and to review their distributions. Steller’s Jays resident in the southwestern mainland are probably intergrades between Cyanocitta s. stelleri and C. s. paralia, rather than pure C. s. stelleri, pure C. s. paralia or intergrades between C. s. stelleri and C. s. annectens, all of which have been proposed previously as the local subspecies.
Key words: British Columbia, Cyanocitta stelleri, plumage, size dimorphism, Steller’s Jay, subspecies, taxonomy
