The Gull Island vole (Microtus pennsylvanicus nesophilus) is a subspecies of the Meadow Vole last collected in 1897. A ground-dwelling coastal beach grass herbivore endemic to Great Gull Island, New York, it disappeared after habitat destruction for naval fortifications in August 1898 for the Spanish–American War. Also, feral cats were also partly responsible in its decline. It is known from fifteen specimens in Washington, D.C.
