Cumberland House, Saskatchewan, Canada.
Genetic differences from P. pica rather weak#R and morphological differences “remarkably slight”#R, so very possibly merits reunification with P. pica along with P. nutalli (which see, below). Provisionally maintained here as separate species, however, for possessing a distinctly slower chatter-call#R (2); a whine-call shared only with P. nutalli (assuming absence from race camtschatica, for which there are no recordings) (3)#R; slightly smaller size (allow 1) but proportionately longer tail (allow 1); supposedly also greener tones in glossy area on wings (ns); and blue vs brown irides in first-year birds (ns). Monotypic.
