Interesting facts:

The longest migration among songbirds is made by the wheatear - a small bird from the Canadian Arctic that weighs just 25 grams. From its nest to its wintering grounds in Africa the wheatear covers a distance of more than 14,500 kilometers. Most of the way they fly alone, reaching speeds of up to 50 kilometers per hour.
