Squirrels

There's a birdhouse nailed to the silver maple outside our family room window. The tree is about 4 feet across, and has some pretty substantial branches. Unfortunately, it's also really close to the house, & I'm a bit concerned about some of those substantial branches landing on the house in a windstorm. But anyway - there's a birdhouse on it, right under one of those branches. Right now, there are 2 soggy gray squirrels on top of the birdhouse, and on keeps poking its head out of the house below them. Apparently they don't have any other dry places to go.
