Marine Birds
Seabirds are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations.
Waterfowl
ducks, geese, or other large aquatic birds, especially when regarded as game.
