Grebes (Podicipediformes) are group of medium-sized freshwater diving birds that inhabit wetlands—lakes, ponds and slow-flowing rivers—in most regions of the world with a few exceptions such as the Arctic, Antarctica and some oceanic islands. Grebes are skilled swimmers and excellent divers. They have lobed toes, a narrow to stocky body and blunt-shaped wings. Grebes have a long neck and pointed bill.
During the breeding season, grebes take part in elaborate courtship displays. Some species swim side-by-side in the water and as they gain speed they lift their bodies into an upright display. Grebes are attentive parents, both males and females care for the young.
