Camptorhynchus

Camptorhynchus is a genus of sea ducks that holds a single species, the Labrador duck, Camptorhynchus labradorius, which is extinct. The Labrador duck was the first known endemic North American bird species to disappear after the Columbian Exchange, with the last reported sighting in 1878 at Elmira, New York, and the last preserved specimen shot in the fall of 1875 on Long Island. It bred in Labrador and northern Quebec and wintered off New Jersey and New England on sandy coasts, bays and inlets. The male was boldly pied in black and white and the female grey, and the bill was soft and broad with many lamellae inside, suited to taking small molluscs from silt and shallow water. Mitogenomic work places the genus close to Steller's eider among the sea ducks. Only 55 specimens survive in museum collections.
