We envy birds, watching them enjoy the freedom of a 3-dimensional space. Flight allows them to get to hard-to-reach places and perform aerial acrobatics in protecting home ranges and searching for food. But it's not always easy – it takes a lot of effort to graduate from air school and there is a new bunch of cadets arriving, all hoping to get their wings.
Thanks to their flying skills birds can go anywhere, often undertaking huge migrations. The Arctic tern is one bird that can even fly from pole to pole. But birds don’t come out of an egg already to programmed for the air. Parent birds work tirelessly to nurture and train their young. As they get older the chicks start spreading their wings and experimenting with flight. Before long they can join their parents in the skies. All we can do is watch in awe and wish we could join them.
