Lake Louise, Alberta. He was flitting around the parking lot, seemingly looking for handouts, then flew off to the top of a conifer. His tail fanned is white with broad black vertical stripe in the middle. He was the only bird we saw as we walked around the lake to the frozen blue icefall. There were some crows or ravens on the road from Banff, and some Black-billed Magpies at the Banff center.
