Good with numbers? Try this for size:
Given that the video's angular field of view was 18' x 14' and that the original frame-rate was 60fps, estimate the speed of the photo-bombing bird and its distance from the camera.
Assume that the flight was parallel to the plane of the camera's sensor and that the bird's speed was constant during the fly-past.
You'll need to suss the size of the bird yourself, and that depends on what species of bird you reckon it was. The best-guesses (according to incoming emails) include Falcon, Gull and Pigeon.
