Several years ago I was in San Francisco and asked a waiter what squab was. He
gestured vaguely outside and said "pigeon". I didn't order it, but I always wonder what
pigeons taste like when I see them on the sidewalk.
The real interesting thing about pigeons as a protein source is that they breed fast,
don't take up much room, live in urban environments, and don't require antibiotics and
hormones to thrive. As the population grows and land availability shrinks, the great
herds of cattle may be replaced by equally large, and faster breeding, herds of free rang pigeon.
