Flight Shot of Whiskered Tern

I just finished processing some flight shots which I photographed at Byram last month. The series of shots were captured with the canon 1 D mk IV and EF 800 IS lens. I set the focus to manual focus and pre-focus at the rotten tree branch. Secondly, I set the camera to shutter priority and set it at 1/1600 so that it is fast enough to freeze the flying subject. I also dialed the ISO to 800 in order to use a smaller aperture of F10. The smaller aperture created a wider depth of field to ensure greater sharpness of the subject. Here are the flight shots :
