A woman in Kendal, England came home to find this ghostly owl print on her window. According to the BBC article, it was caused by the owl's "powder down" when it flew into the clean glass. The article says powder down is a protective substance on growing feathers. Wikipedia, however, describes powder down as the type of feathers themselves, which disintegrate at the tips over time, causing "feather dust". Either way, it sounds extremely sneezy. But pretty, isn't it?
