A crimson cardinal perches in a snow-covered apple tree, considering whether he will fly to the bird feeder. Chickadees flit from tree to feeder and back again; they are not shy. But the cardinal is a shelf feeder, and this bird feeder is for perching birds.
Nuthatches--which my partner calls upside-down birds--hop up or down a nearby wild cherry tree. Gravity doesn't seems to concern them.
The cardinal launches himself toward the house and grabs a bite to eat.
I smile. Winter bird-watching feeds my own joy.
