How do birds stay warm in winter? With their downy feathers, of course — but a cozy scarf can’t hurt, either. Includes my curious discoveries on the back of each card. Blank inside.
Text on the back of this card:
The chickadee is one of my favorite birds. During the winter, chickadees can keep their bodies at 100ºF despite below-freezing temperatures outside. Like other birds, they stay warm by maintaining air pockets within their clean feathers – much like a scuba suit allows a diver to heat up the air between body and suit. So preening those feathers dry and clean becomes all-important for staying warm (for the chickadee, that is – not so much for the scuba diver).
Other reasons we can love the chickadee: she’s smart enough to enact a mild hypothermia at night, conserving energy by dropping her body temp by 10-15ºF. And, she makes sure to eat about 35% of her body weight each day during the winter.
