Mariana mallards (Anas platyrhynchos oustaleti) were endemic to the western Pacific islands of Guam. Tinian, and Saipan. Surveys for this endangered subspecies that were conducted on Tinian, Saipan, and other islands in the U.S. Commonwealth of the Northern Mariana Islands (CNMI) from 1983 through 1989 show that the mallard no longer occurs there. Following extirpation of Mariana mallards on Guam in the 1960s, this island subspecies is now extinct. The major causes of extinction appear to be overhunting of small populations and habitat loss.
