The great snipe might not be the fastest bird in a sprint race but it'll sure win the marathon! A 2011 report showed that this species blows other migrating birds out of the water for the fastest long-distance non-stop flight. The great snipes tagged by researchers traveled from Sweden to sub-Saharan Africa in a mere two days! That's about 4,200 miles, at an average speed of 60 mph, without any rest. No wonder they nearly double their weight before making the lightening-speed migration. Other bird species may migrate farther (and we have a record-holder that we'll get to soon), but they take much more time, including taking pit stops, to get there.
