one of these birds. A long sequence was made of a large shearwater- petrel. Equipment was put under plastic cover while attending meals and secured shortly after sunset. NOTE - 48 FPS are being used so that even if the bird is in the field of the lens for a very short time it will have a reasonable screen-time. The slow motion caused by this speed will likewise give greater opportunity to show wing patterns but not necessarily flight patterns in general. Once the bird is in the field of the lens and the lens is stopped down to f/32 or f/122 it is difficult to follow due to the very low intensity image reaching the eye through the single-lens viewing feature. Hence very short scenes in many cases.
