A hen duck calls her ducklings to jump 12 to 15 feet to the ground from the hollow tree where they hatched, and they did. I was stunned to watch them dropping out of the tree one by one as fast as they could. I caught the last two dropping in this video, and then at the end the mother can be seen at the bottom by the fence spying back at me. I was lucky to see that. I hope they are lucky enough to survive the wilds of my yard. Sweet ducks.
