This
robin is in a blizzard. The wind is blowing 35 to 45 mph, and
gusting to 70 mph!
"The
storm started around noon on January 22nd and ended mid-day Sunday,
January, 23rd. Overnight temperatures on Sunday evening went down
to 6 degrees," says John Deignan, who took the photo in 2005.
What
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.
