The birds spent the whole day feeding, I spent the whole day taking pictures of them feeding. Both happy. Exposure info: Shutter speeds, most at 1/2000 of second at f/16, ISO 3200, some at 1/400 or so. Prefocused, auto focus off, manual mode, 100-400 Canon lens. Judiciously cropped. These best from about 700 shots, but then, "the film is free". Click to enlarge.
