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.

Mites and lice and fleas: Oh my!
Have you ever watched a scratching squirrel? Those little paws move incredibly fast, and I swear, their under-the-armpit maneuvers mimic taking a shower. I wrote a blog post about itchy squirrels a year ago, surmising that their den was infested with fleas. This past week, quite a few creatures’ itchy behavior caught my eye: the squirrels, a juvenile bald eagle, adult and juvenile swans, and two kinds of ducks—goldeneyes and mergansers.

Mergansers are a common sight–pun intended– on Lake Allegan.
Common Mergansers, or Mergus merganser in ornithology-speak, are social creatures that flock in groups up to 75 individuals. I usually see about half that number, most often in late winter and spring.
These small diving ducks seem to prefer the main channel of our river-turned-lake. In winter, the water beneath our home will freeze. But the main channel’s deeper, swifter water generally does not. So, as the lake began to thaw after the recent polar vortex, I was doubly surprised to see mergansers close to our shore. Not only were they diving for prey in very shallow water, but they were also fishing beneath the ice.
Picture whack-a-mole without the whacking.
