I went up to Elbow Falls last weekend for the sunrise but I stayed for the American Dippers (Cinclus mexicanus).
I love watching these aquatically adept birds stalking, diving and swimming in the middle of the rapids. On the last visit to the waterfall, there were three Dippers flitting about moving between the bottom of the waterfall and the rocks at the top.
They chased each other down river a couple of times but spent most of their time fishing alone. On a quiet morning in Kananaskis, it was nice to spend my time watching them.
