Aleutian wild cattle are feral wild cattle found on the Alaskan Aleutian islands. Several attempts have been made to round up these cattle for ranching. [1] [2] From 1985 to 1986, the cattle on the Shumagin Islands were eliminated by the U.S. Fish and Wildlife Service, [3] [4] but they still remain on Umnak Island and Chirikof Island. [2] [5] As of 2023 [update] , there were approximately 2,000 cattle on the island. [6] Their origins are not known; genetic testing shows them to be genetically distinct from common American commercial breeds, though related to Highland cattle. [7] [8]
