I was lucky enough to be with birding friends at Inglewood Bird Sanctuary on 16 April 2013, when about 10 gorgeous Mountain Bluebirds were flying over the Bow River and landing on the rocks not too far from where we were standing. They repeated this a number of times. Thank goodness for zoom, lol! I never realized how grumpy these birds look when you see them head on! Normally, one has to drive out of the city to see these birds, so it's always a treat to see one within city limits.
