WARNING: The following nature video contains graphic violence against a mouse. Mouse lovers and those with queasy stomachs may wish to consider waiting for the next video of cute babies.
Actually, it is not so bad. And it is very important for young owls to learn how to fend for themselves. Momma is letting them do that more and more even as they remain in the nest box. Mice are delivered and left to be picked apart by the young or fed to them during the day. This is only the second time I have seen one of the owlets take it upon him/herself to eat the whole thing alone. After they fledge, I will clean out the box and look for owlet pellets for use in nature classes. It will be fun to see if we can separate mice from voles.
