Greater Yellowlegs

During the Nisqually National Wildlife Refuge Christmas Bird Count on 14 December 2019, Erika and I watched a Greater Yellowlegs hunting. The species visually locates its prey—usually small fish—and then swiftly plunges its head into the water. Other feeding strategies are known, depending on time of day and habitat. Yellowlegs will also take insects, snails, small clams, toads, and worms from muddy shorelines or directly from the air. In some freshwater locations, dragonfly nymphs are a major food source and are more often consumed than fish. Greater Yellowlegs are also known to eat crowberry berries (Elphick et al. 1998).
