How Do Robins Keep Warm in Winter?
Article | Journal Page

This robin is in a blizzard. The wind is blowing 35 mph and gusting to 70 mph! The blizzard will last for 24 hours. The night temperature will drop to 6° F. Brrrr! How can robins survive such weather?
Seeking Shelter
During storms, birds try to get as sheltered as they can. Like this robin, they take shelter in bushes, near buildings, or in trees. (No nests! Nests are not shelters, but only cradles for baby robins.)

Fluffing Feathers
What do you notice about the robin's feathers? The bird fluffed up his feathers for protection from the cold. This fluffiness is important. Fluffed-out feathers insulate the bird’s internal organs so they stay at 104° F. Feathers themselves are such good insulators that the outside of the feather is cold, like the air. But, just a few millimeters under the feathers, the bird's body temperature is a cozy 104°F. Snow doesn’t melt on cold feathers, so the feathers stay dry. Layer upon layer of feathers are the world's best insulators!

Consuming Calories
Foraging and eating are the main winter activities of birds that stay in the colder north. Their sharp eyes find shriveled berries left on trees and bushes. Their beaks poke in leaf litter to find any insects.
When fruit starts getting scarce, robins usually leave. They don’t want to be stuck during a storm in a place where there’s no fruit left. Robins do most of their wandering on nice days as they travel to find good food sources.

What About the Feet?
Even when standing in snow, a robin's feet don't get cold. Their circulation is so fast that the blood doesn't have time to chill. Thanks to the design of their blood vessels, blood shooting up the toes and legs is heated by warmed blood flowing back from the bird's heart. The exposed part of a bird’s legs and feet don’t have muscles that require a lot of blood flow to work them. The feet open and close by tendons, rather than muscles which require more blood to power them.

Still, birds fluff their belly feathers to help cover the toes and keep them warm. Robins are well designed for all weather!
