My feathers are fluffed to keep me warm...
As I wait for breakfast at winter's dawn.....
There is shelter here as it stormed,...
Fresh snow has fallen and icicles formed.

Even in freezing temperatures, robins can stay warm enough to make staying through the winter worthwhile. ... It's amazing, the way they survive winter is they fluff their feathers and get really big. Their internal temperature is 104° F and yet they can be in areas below freezing. They normally eat berries but when really cold they may accept raisens and small Apple pieces.
