Migration is an extremely gruelling journey, with most waders travelling thousands of miles to reach their breeding grounds. Stints and knots are among the waders that migrate for the longest distances. In a recent research, a Red Knot was recorded to have flown for six days and six nights non-stop, covering a distance of 5000 miles! Imagine the toll such a journey would take on their little bodies. This is the reason why birds need to fatten up before they embark on their epic expeditions.
