Range – north America from coastal southern Alaska, central British Columbia, and the southern halves of Alberta, Saskatchewan, and Manitoba, through the Rocky Mountains down south to all the Rocky Mountain states including New Mexico, Colorado, Utah, Wyoming, and Idaho.

Within this area Pica pica is widely distributed, breeding at most elevations up to10,500ft.(Ligon,1961)”
