Working outside today -- have laptop, will travel. Sitting by the river watching a sparrow take a dirtbath. He's about a foot away from me, but I think he thinks I'm part of the furniture. The gravel at the area with the chairs and tables has a sunny corner protected by a low wall which the sparrows have made their spa. They fly down in small groups, or, like this guy, alone, and roll around in the dirt until their feathers are all fluffed. They preen, roll around some more. This guy's really going at it. But I guess it's too early for the after-lunch bird crowd, because he's all alone.
