We went out spotting birds in the snow and freezing air and spotted this harrier (Circus cyaneus) right at the limit of my longest lens. We got a better view with a spotting scope but this was the best of a series I took. Birds are interesting subjects for photos and it can be challenging to get them in the best of conditions. I appreciate really long and really sharp lenses in these situations. This was taken with about a 1200 mm equivalent.
