Now I know what our sparrows do when they think I'm not watching. For weeks I'd wondered why the water level in the heated birdbath goes down so rapidly. Aha. They made such a wet splattery mess that the back window through which the long lens peeks (see the blogpost below) had to be washed and dried.
