BOB these are all taken at the time they are nesting ?When they fly I wait till they are coming back to the nest . I home in on them as they are coming back . when they come closer they have to fly a little higher to get to there nest . This is the best time to get them . In this shot he is almost level to me & he is starting to fly up . This is when I take the photo. It also has a lot to do with the lens you are using ???
