* Deer: The most important prey species for the Alexander Archipelago wolf, especially Sitka black-tailed deer.
* Mountain goats: These are a significant food source in mountainous areas.
* Moose: While moose are not as common in the archipelago as other prey, they are sometimes hunted, particularly in areas where moose populations are higher.
* Salmon: During the spawning season, wolves will opportunistically eat salmon, especially in areas with abundant salmon runs.
* Small mammals: This includes beavers, marmots, rabbits, squirrels, and voles.
* Birds: Occasionally, wolves will prey on birds, especially during the nesting season.
* Carrion: They scavenge on dead animals whenever available.
The exact composition of their diet can vary depending on the availability of prey in a particular area. However, deer remain the most important prey species for the Alexander Archipelago wolf.
