Recently I received a 2015 calendar from the Canadian Wildlife Federation and the month of December for next year is illustrated with a picture of a Common Redpoll (Acanthis flammea).   A few notes state that redpolls can survive winter temperatures to -53C and during the winter months, they have been known to tunnel deep into the snow at night to stay warm.   The tunnels are burrowed 10 centimetres into the snow and can be more than 30 centimetres long!   Smart birds.

Please comment if you wish.
