Not a great shot but for me the degree of difficulty makes it one I was happy to get. I’ve been trying for weeks to get a photo similar to this one, taken 6 days ago in the Wasatch Mountains.
Cornell’s Birds of North America Online calls Mountain Bluebirds one of the most sublime songbirds in North America and I agree. The cerulean blue of the male is simply spectacular and females and juveniles show some of it too.
