Bartramia is a medium-sized bird from the sandpiper family. It lives on grassy plains, has long legs, a long tail and a small head.
Bartramia differs from most sandpipers in that it lives on dry meadows far from water bodies. It is important for nature because it eats harmful insects and serves as food for predators.
