Rare looks at birds from the inside of a tree cavity! In this episode of Backyard Birds Revealed, learn about the ecosystem of woodpecker holes—why they drill holes and who else benefits from them. You may have seen woodpeckers, nuthatches, and titmice moving up and down a tree and going into a hole. But you’ve probably never looked out from the hole to see the birds looking in. For this Backyard Birds Revealed episode, filmmakers Tim and Russell Laman create a clever setup, connecting a camera to a woodpecker hole to capture the detail of the birds looking in.
