When camping one time, we could hear an awful racket coming from up in a tree. It sounded just like several puppies carrying on.
The next day, I asked the Ranger what the heck it was. He laughed and said it was a nest of owlets whose mother had stopped feeding them because they were overdue to leave the nest.
They were hungry and mad as hell.......MOOOMMMMMMMMMMM!!!!!!! WE'RE STARVING!!!!!!! THERE'S NOTHING IN THE NEST TO EAT!!!!!
The next night was just as bad. We moved on after that. I sure hope Mama Owl convinced them to go hunting.
