One of Nature’s Mysteries to Solve

Hey, there! Today’s mystery is the lines of holes in the tree, not the tree itself.

Do you know what made the holes? I’ll be back later!


These neat lines of holes, covering this cherry tree—we think! Forgot to look too closely, it might be an apple tree—are the work of the Yellow-bellied Sapsucker.

This medium size woodpecker makes the holes, not because he hears insects in every millimeter of the trunk, but because he wants to attract insects to the tree. The holes he drills ooze with sap, sweet tree sugars, which the bird eats, but also that the insects come to feed on. Then the sapsucker returns and feeds on the insects.

Pretty clever, huh?  I wonder how long bird evolution took to come up with this trick. If acorns had legs, squirrels would have thought of it first.
