Yesterday I posted a photo of what I thought where the only Sandhill Cranes that I saw in the sky. I mentioned photographing large flocks of what i thought were geese at very high altitude. When I went to process a photo I only really looked at the last few. I just looked at all of the photos of "geese." They weren't geese but were very large groups of Sandhill Cranes! I had no idea they migrated in such large flocks.
