do ducks feet get cold swimming in winter?

Question

you would think that they would but it doesn't seem to bother them.

Answer 1

Their veins and arteries lie in contact in the legs. This counter current flow allows arterial heat to rewarm the venous flow before returning to the body. Arterial blood entering the feet has given much of its heat to the returning blood. The blood vessels in the feet constrict minimizing blood entering the feet. The birds standing on shore can tuck one leg up at a time.
The juncos that forage in my garden in winter flocks will be scratching along when they suddenly drop to the ground covering both feet. They do it in amidst the feeding group so I assume they see no reason for alarm at the moment they choose to do this since the others are all calmly continuing. It could be a toe warming break.

Answer 2

no, the water's always above freezing and at that temp their feet are ok. they DO get cold feet though if they're out and the temp is substantially below freezing. the cold ground makes them so cold they drop to the ground and pull their feet up into their feathers so they're not very mobile if its really cold out.

Answer 3

definite somewhat in many cases. there became into an previous guy that lived not far from us and we'd go swim in his pond and capture frogs,chase dragonflys and merely have relaxing till he died and his relatives by no skill enable us to back on the valuables.

Answer 4

they're probably like used to it. or during evolution,it changed.
