@chris1948 a couple of years ago I heard that a lot of Snow Geese were being seen at Anahuac National Wildlife refuge, so I went out to see if I could get any good pictures. After driving around for about a couple of hours, I was about to give up when I saw this cloud headed in my direction so I pulled over. It was a flock of Snow Geese and they landed right in front of me. I sat there watched and took pictures for an hour and they were still landing. Here is a video I shot. Watch to the end where I pan across the whole flock.
