Where Do Pigeons Go At Night?

One of the great mysteries of life is where pigeons go at night. During the day they're everywhere, they're on street lamps, strutting around sidewalks, flying in your face, but once it goes dark they vanish. Their disappearance reminds me a lot of how homeless people tend to disappear from the streets during Winter. That's when I remembered the Pigeon Lady from "Home Alone 2: Lost in New York". She was homeless AND was covered in pigeons and in the climactic scene she rescues Kevin from Joe Pesci and Daniel Stern AT NIGHT. So there you have it, that's the answer. The pigeons are all with that crazy bitch in Central Park somewhere hiding from society. The answer was right under our noses this whole damn time!
