These frost patterns formed on a window pane inside my grandparents house, which had been closed up for the winter. The time of day was late afternoon, and the background, the mountains to the east.
Looking at the photo, I thought of birds flying up into the evening sky. When I came back the next day the patterns were gone.

This is photo is my most favorited image on Flickr (by far). Going back thru my comment history, I found 6 other photos of frost patterns that merit viewing. These are all beautiful photos and show a great diversity of frost flower/feather forms
