Challenge 7: Can you find any signs that birds have left behind? It may be holes in trees, feathers on the ground, old nests, or more!

Now is a great time for birding. The changing season have birds more active, but the leaves are not yet fully out to cover the view!

What evidence did you see? Take a photo of what you found and come up with a hypothesis of what kind of bird may have left it behind. Do you think it is a large bird, or a small bird? What would a bird need to leave that sign? Share your findings!
