Every autumn, billions of small birds make their way from the continent of Europe all the way to Africa. As soon as spring arrives these birds re-trace their epic journey back to Europe to breed. The journey which involves crossing the Sahara Desert, the Mediterranean and even the English Channel is amazing given how small some of these birds are and considered one of nature's miracles.
