Geese will hang around all winter if they have open water and can find

They cruise at fifty or so, they can make it from Canada to Mexico in
one day. They can split for the coast anytime. They fly as high as 27
000 feet, you know they can take the cold. That is in what the climbers
call the Death Zone, where you die without bottled oxygen, but they have
lungs of titanium or something.

Yup, it's the food sources that drive the birds south, not the cold.
Hell, down is very good insulation.
