The outdoor thermometer said -20 F (-29 C) when I went out to get the newspaper this morning. No birds and no squirrels at the feeders, nothing is moving in the backyard except the remaining leaves and branches on the trees. There is a -35 to -40 F windchill today that has closed some schools. Tough conditions for a California-raised girl to tolerate.
As I am writing this post, the sun finally hit the feeders and a few brave Juncos ventured out to feed. So, I guess they get the award for most cold-tolerant birds of the backyard (or the hungriest). I suspect the chickadees, nuthatches, and woodpeckers stay tucked into their nocturnal roosts and feed off their stored larders in this kind of weather.
