Not my picture (I found it on the internet) but this WAS my morning. A class trip where I was the only show turned into a private tour as my ornithology instructor and I went looking for Sandhill Cranes. We saw some in the distance and we pulled over to look for other birds. At that EXACT moment 1000's of snow geese flew about 20 feet directly over head. It took about ten minutes, plenty of time to grab my camera, but I was too entranced to get it out of the truck. Great noise they make.
