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.
