- [Narrator] They call it the city that never sleeps, and pigeons have also embraced the 24-hour lifestyle of the Big Apple.

In the heart of Midtown Manhattan, Times Square is a world of lights, steel, and concrete.

On the face of it, not much of a haven for wildlife, unless, of course, you're an urban specialist.

(pigeon coos) The pigeon gang here has completely embraced this never-ending show of sound and light.
