“My entrance into the courtyard caused a small stir among the lookouts. I could tell because in the middle of February, in the dark of night, Baxter Terrace suddenly sounded like an Audubon Society refuge - birdcalls being the latest in urban drug - selling counterintelligence...

Birdcalls allowed much more information to be imparted to other members of the operation, without the visitor being aware of what was being communicated. So while a crow's harsh cry could harken the arrival of a member of the city narcotics unit - a significant threat - the sweet song of a chickadee might signal an officer who was merely escorting a social worker to an appointment allowing business to continue in guarded fashion. Someone like me, a stranger on unknown business, might warrant a whipporwill's call.

Where exactly a city kid learned what a whipporwill sounded like, I have no idea. But these kids were nothing if not resourceful. It makes you wonder what they could have accomplished under different circumstances.”
