Spray Lakes and Kananaskis Valley

the people at the Lake Louise visitor centre suggested the Spray lakes round out of Canmore was the best place to look for our, so far, missing Moose so a quick recky on the late evening of the 4th revealed a superb site with so few people compared to the Banff area; the next morning we were up there bright and early; an American Osprey nest on the track side, Spruce Grouse scuttling off into the trees, 50+ Chipping Sparrows, Hermit Thrush, Audubon's warblers, Common Loons, Spotted Sandpipers with a nest, Ruddy Duck with a pair of Barrow's Goldeneye, my first birds since the drenched Scottish bird, Cooper's Hawk, 3 Bufflehead, singing Swainson's Thrushes (one in typical tree summit pose here), Northern Flicker, Tree and Violet Green Swallows all made for a good start -- how many people would identify this female Barrow's in the UK?
