Rock Pigeons are one of the most common urban birds so why do we never see baby pigeons?
Some baby birds - like down-covered ducks, geese, and chickens - leave their nest shortly after hatching and do a lot of growing up while following their parents around.
Others, like pigeons, depend on their parents to feed and protect them, well into their youth.
They stay in the nest - under bridges and awnings, for instance - until they're nearly as big as the adult birds.
