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]
