Why don't a duck's feet or legs freeze in icy water?

Maybe ducks are like sled doggos, where they are so well insulated by their feathers/fur, that they have to use their extremities as heatsinks to prevent them from overheating, even in freezing cold environments.

@ragingloli – Interesting. I wonder if that is true.

But they don’t have feathers or fur on their legs.

Blood has a lower freezing point than water. If the duck is swimming in it, and the water isn’t frozen, then neither are the duck’s legs.

Why do ours “freeze”?

Excellent @josie.

@josie -Thanks for that. I think of it every time I see them in winter.
