Naturally Speaking

It is uncommon to hear a winter day, one with a cloudless, blue sky, particularly after a snowfall, being described as a bluebird day. But that is the best and most precise description of a bluebird day.
Bluebird days really do not have much to do with spring (or Bluebirds for that matter).
Here in Wisconsin, however, those December days may actually be days when real Eastern Bluebirds, those who have decided to tough it out and stay until their flock-mates return from being anti-snowbirds in the south.
Look for this thrush family member perched on power lines, possibly near nest box locations or spring watering holes.
It is unlikely Bluebirds, or Robins for that matter, will find their favorite foods on winter bluebird days, so they turn to frozen crabapples and other tiny fruits left on the vines. Grapes and bittersweet will serve, too.
A likely truism about winter blue-sky days is an old saying: "On a beautiful bluebird day, the girls ride snowmobiles."
