Whistle sleuths, who/what's making noise in the middle of the night?

My Chicago apartment faces an alley. Occasionally, in the middle of the night, I'll hear a series of three whistles coming from the alley.
At first I thought it was a person, but I heard it last night and thought it might be an owl or some other nocturnal bird because of the strong, steady tone of the sound. I asked some friends about it today, and they thought it was a signal to or from a drug dealer. If that's the case, it seems like cops could easily go undercover and bust the whistler.
So where's the whistle coming from? Is it a person or animal, and what kind of person or animal is it?
