Introduction of Foxes to Alaskan Islands - History, Effects on Avifauna, and Eradication
Foxes originally were absent from most Alaskan islands in the North Pacific. Red foxes (Vulpes vulpes) were indigenous to the Fox Islands in the eastern Aleutians and to some islands off the Alaska Peninsula and in the Gulf of Alaska. The first recorded introduction of foxes was in 1750 when Russian...
