The Red-fronted Coot is distributed from southern Peru and south-eastern Brazil to Tierra del Fuego in Argentina. In Chile it is found from north of Santiago to Puerto Montt but I saw a Red-fronted Coot at the Parque Nacional Chiloe, which I think might be a small range extension. It seemed to be nesting.

The bill is yellow and the frontal shield is a deep red. The white undertail coverts are conspicuous when swimming away from you.
