In an impressive feat of parenting, two bald eagles managed to keep their eggs incubated and warm during a winter squall in Pennsylvania that left them up to their necks in snow. The eagles took turns caring for the eggs, somehow managing to flutter their way out of the snow to allow the other to take a shift.
"Eagles, and many other types of birds, are well-suited for even the snowiest of winters; their feathers are fantastically insulating, and they can lift and lower their feathers to regulate heat. Even better, they have a single patch on their bellies that aren’t covered in feathers, to enable easier transferring of heat from the mother eagle to the eggs."
