The young woodpecker made a proud show of his loot.
Red-bellied Woodpeckers are well equipped to forage. Their bills are built to chisel, hammer, and drill. They have long, sticky tongues with barbed tips—perfect for reaching into crevices and pulling out prey.
These birds are omnivores, happy to eat seeds, nuts, fruit, and meat. They’re both aggressive and tenacious. A few months ago, I filmed a Red-bellied Woodpecker pounding the life out of a bat before flying it away for consumption. At feeders, these woodpeckers will swipe peanuts from under squirrels’ noses. And when they find a hard-shelled seed or nut, they know exactly what to do: Wedge it into a tree crevice and hammer. They’ll catch the pieces with a cupped wing or trap them in belly and breast feathers pressed into the tree.
So, when the immature woodpecker leaned into a crevice with a nut in his bill, I expected to see a speedy pound-and-swallow maneuver.
Instead, I saw a fumble.

An all-caterpillar diet does not have to be boring.
That’s what I concluded as I watched Baltimore Oriole parents feed their nestlings during my recent nest-watch. They brought wiggly larvae in all colors, sizes, shapes, and textures: green, white, black, skinny, plump, smooth, striped, bumpy, and hairy. Aside from the occasional dragonfly and moth, the nestlings’ diet seemed pretty predictable.
Until they were about four days old.

You’ve probably seen birds fluff their feathers in winter.
The fluffy feathers form little puff pockets of air warmed by the birds’ bodies. But… have you ever seen a bird with feathered feet?
In the past few weeks, I’ve watched geese stand immobile for thirty minutes or more on ice and in shallow, frigid water. They seem unconcerned about freezing their feet. Turkey vultures poop on their feet to cool them off in summer. Is it possible, I wondered, that the geese are dropping little toe warmers, and I never noticed?
I reviewed hours of video featuring geese on ice. Nope. Nary a plop.

The loon was wagging its tail.
Such a happy creature, I thought. Then I returned to my senses. Loons are not puppies, whose joyful exuberance might be measured in tail rotations per minute. Could the tail swish be aimed at keeping insects away? Not likely. Conditions were breezy on Farm Lake, just windy enough to keep flies and mosquitoes at bay. Surely, the loons enjoyed the same benefit of that day’s Algonquin weather. My kayaking partner and I headed for a closer look.
As we approached, the wagging continued. Six or eight shakes, then a pause, followed by another series of rapid flapping. The flag-like end of the bird’s tail seemed improbably large. I peered through the camcorder’s viewfinder and bumped up the zoom. The camera jiggled from the kayak’s unsteady movement, but the loon’s details came into view. That’s when I realized my mistake.

Can you say ‘zygodactyl’ three times, fast?
You learn the most interesting things when your bedtime reading is the Peterson Reference Guide to Woodpeckers. My most recent discovery is about woodpecker feet. I already knew that most woodpeckers have zygodactyl feet: Two toes face forward. Two toes face backward. That toe arrangement gives them superior grip strength when clinging to a tree trunk. Their massive claws help, too.
What I did not know is that the multi-talented woodpecker has articulating pinkies.
