Malacorhynchus

Malacorhynchus is a genus of duck within the family Anatidae.^[1] It was established in 1831 by English ornithologist William Swainson, when he proposed moving the pink-eared duck into a subgenus (Malacorhynchus) based on unique characters of its beak and toes.^[2] The genus contains one living and one extinct species.^[1][3]
