There's a little bird shopping the real estate inside our dryer vent. It's warm and cozy in there, apparently, and he sang me a pretty little song the other morning as I came down the stairs, which resulted in some screaming by the kids(and me too). Then some frantic flapping noises ensued followed by silence after he finally found his way out. A couple of days later he was back. Dangerous neighborhood, but the climate is good and the other tenants are all talk and no bite.
