Our injured woodpecker

During dinner at home last night we heard a loud crash from the kitchen, as though the entry door had slammed. The door was securely closed, but a bird lay injured on the ground outside. Confused by reflections of the sunset, it had flown into the glass window of the door. I feared it had broken its neck, but it managed to stay upright when placed on the woodpile. Black and white plumage with a red underbelly identified it as a Greater Spotted Woodpecker. We often hear but seldom see woodpeckers in the forests around here. After a while it was showing no signs of recovery, so we placed it in a cardboard box for the night. This morning, fearing the worst, I opened the box and was delighted when our woodpecker flew away into a nearby tree.
