Hoo hoo hoo

The full moon, the "Snow" moon shining brightly last night. Getting up early recently to shovel out the driveway, sound of an owl.

For sounds in winter nights, and often in winter days, I heard the forlorn but melodious note of a hooting owl indefinitely far; such a sound as the frozen earth would yield if struck with a suitable plectrum. I seldom opened my door in a winter evening without hearing it; Hoo hoo hoo, hooer hoo.
