Learning About Wolves in Yellowstone

Last group learning for the night. We have been learning all about the recovery of the gray wolf in Yellowstone and how it has stabilized the coyote population. I didn't get it. Aren't they the same. I decided it was because the wolf must be bigger. But then I saw the footprint difference today. Puppy dog size versus big. The kids want so badly to see a wolf. Awesome book... When the Wolves Return. I might have bought it after we kept the library copy on repeat. #homeschooling through Yellowstone!
