I wondered how birds survive winter so looked it up a few months back and it seems the go into 'torpor' during cold periods, even sometimes daily. It's like a mini hibernation where they slow down their body temp and metabolic rate. I had no idea but am impressed

That shows how clever nature can be.
A bird can fly 3 thousand miles, fall asleep while doing it and still arrive at the exact same pond as the previous year.
A human cah have sat nav and still get lost.
