This American Tree Sparrow looks about as cold as I feel whenever I go outside nowadays. We've had snow, wind, and well-below-freezing temperatures for what seems like forever, and there's no break in the foreseeable future (which is to say, at least the next 10 days or so, as far as the weather report will predict). Temperatures tomorrow night are supposed to hit a low of -14 degrees F. Without windchill! Yikes!
Stay warm, little bird. We'll keep the feeders full for you.
