Migrating birds

We went for a walk this afternoon since it was a nice day, albeit a bit cool and breezy. As we were walking down a road not far from here, we heard squawking sounds, causing us to look up. There was a huge flock of cranes, flying north in formation, honking as they went. There were probably about a hundred of them. Before they were even completely out of sight, along came yet another flock, of similar size. What a beautiful sight to see!
