Guide to Boreal Birds
The larger of the two yellowlegs is a noisy and conspicuous bird. It is also more wary than its smaller relative and flushes at a greater distance. It often runs about wildly in shallow water or wades up to its belly and occasionally even swims. With its long legs, it easily obtains food in pools. The bill, slightly upturned, is used to skim small animals from the surface of the water as the bird swings it from side to side. This behavior, seldom seen in the Lesser Yellowlegs, makes a Greater Yellowlegs recognizable at a long distance.
