robin is in a blizzard with winds of 35 to 45 mph and gusts
to 70 mph. "The storm started around noon on 1/22/05 and ended

do you notice about this bird's feathers? They
are so fluffed up that
he’s holding his wings down a bit. The bird fluffed his
feathers to protect himself from the cold. This
fluffiness is important. It insulates the bird’s internal
organs so they stay at 104 degrees F. The heart and lungs
are pretty far back on birds,
and the back feathers help keep these internal organs warm.
If it's 6 degrees outside, what is the temperature difference
between the air and the bird’s
heart and lungs? Now you see the importance of those fluffed-up
