Snow started falling while video-ing this owl. Several birders were watching him or her from busy State Route 72, 3 miles west of Shannon. The bird was 440 feet away, hence this footage is cropped by half vertically and horizontally. The distance was estimated from the size of the bird (2 ft), the 18% of the 3.92 mm-wide CMOS receptor (how much the bird covered the frame), and the maximum focal length of the camera (78mm) x 2 (tele-extender attached). Let me know if my calculation is flawed.
