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:
Have you ever seen a cardinal shiver?
Me, neither – but it’s not because they wear cozy scarves. In fact, cardinals do shiver like many birds, but it’s not the bone-chattering variety that we’re used to seeing. Instead, they contract opposing muscles deep inside their bodies to keep warm, especially at night.
This is perhaps why we see birds first in the morning and late in the evening – to follow the overnight energy needs. In the morning, birds eat to replenish the energy they used up during the cold night. And in the evening, they snatch up a snack to bolster reserves for slumber.
All that said, if you do see a cardinal shivering (or wearing a scarf, for that matter), do let me know.
