Wildlife & Ecology
Animals, plants, and the places where their lives intersect.

Why does a beaver leave a stump shaped like a pencil?
A yellow birch in Michigan was collected halfway through the job. Its narrow waist and a loose wood chip let you read what the teeth did.

What came out of a D-shaped hole in an ash tree?
Two insects left doors in ash bark. One opening is twice as wide as the other. Read the ruler, pick the beetle’s exit, then check your eye against a penny.
-
Why would a woodpecker drill its holes in rows?
On May 19, two holes in a Michigan tree held sap. By May 20, both were dry. Take a look at the bird’s next move and decide where you’d watch tomorrow.

Who left those marks on the tree?
A trunk ruled in little holes, a tiny D in ash bark, and a birch whittled almost through. Take a close look at each, then pick who you think made it.
