The sky and ground nearly rhyme in their oppressive whiteness. A red squirrel sounds as if he’s having a psychotic break, trying to defend a hollow black locust no doubt stuffed with acorns and walnuts.

A warm breeze at sunrise. My reading is interrupted by an unfamiliar trill: a redheaded woodpecker in the dead crown of the tallest black locust. I watch through binoculars as he works over the tree and himself, probing under bark one moment and under his wing the next.
