Maybe it's trying to get inside so it can stay warm?
It's snowing - yuk, I thought this was supposed to start on Friday - so I'm starting to get ready for "snow feeding": patio table and lounge chair are covered with boards to keep the areas underneath dry for ground feeders. Birdbaths are full, hanging feeders are topped off. Now to make a nice suet-peanut butter-mealworm mix...
