Owl Howl is a really cute story about a little owl who is crying in the forest. Lots of animals stop to try to comfort him. A crow offers to play, a squirrel offers a nut, and the beetle tries rocking her in a cobweb, but she just keeps howling. Finally, the baby owl flies to her Mommy and when Mommy Owl asks what's wrong all the forest animals stop to hear what all the commotion was about. I'm not going to tell you what she says because it's a cute ending and perfect for preschoolers.
My own little owls don't need any help in the howling department but just for fun I made them some owl megaphones. I took a paper cup and cut out the bottom. I didn't use plastic because of the edges. Stryrofoam would also work.
