From the large birds to the small bird, specifically the sweet chickadee. They're very hard to photograph, because they are fast and because their little dark eyes blend into the black cap. Trying to get pictures is an exercise in patience and concentration. I have lots of blank-nothing images, space where the chickadee had been a split second earlier. First there's the call, not musical, then there they are... observing everything. They know what they want, namely food, and they'll check it out carefully before moving in for the snatch. Speedy chickadees.
