The Hawaiian coot is a medium-sized black waterfowl that lives only on the Hawaiian Islands. It has a white bill and a large white frontal shield, and its toes have lobes for easy swimming.
The Hawaiian coot differs from related species by its smaller body size and bright white frontal shield. It is important for Hawaiian nature as an endemic species that helps spread seeds of aquatic plants and serves as part of the local food chain.
