What do baby birds do?
Fun Fact: No one has ever seen a baby pigeon in New York City, despite the countless pigeons everywhere. There are lots of theories to explain this -- they are raised elsewhere and come to the big city later before leaving to raise children elsewhere; people just don't notice the baby pigeons; etc.
I prefer the following explanation: those are the baby pigeons. The full grown pigeons are the size of men, and flightless, and live in the subways.
