Gracefully she spreads her wings amd swoops toward the earth. Then she changes course rushes back trying to reach for the skies. Is she trying to dodge snow flakes as they flutter slowly to the ground? Shake them off her plumage? Maybe she is trying to warm herself through the exercise.
I prefer to think she's just enjoying herself in the snow. Celebrating drops of prettiness that are transforming the landscape and she gets to watch that change as she swoops in and out of the sky. Did she just let out a caw of happiness?
