Short-billed Dowitcher
Limnodromus griseus
Adults' bodies are dark brown on top and reddish underneath. The tail has a black-and-white barred pattern, and the legs are yellowish. The three subspecies have slight variations in appearance: Limnodromus griseus griseus has a white belly and barred flanks. Limnodromus griseus hendersoni has a reddish belly and spotted flanks. Limnodromus griseus caurinus has a white belly, heavily barred flanks, and a densely spotted breast.
