Mammals:
* Arctic foxes: Foxes are opportunistic hunters and often prey on ground squirrels when they emerge from hibernation.
* Wolves: Wolves may occasionally prey on ground squirrels, particularly during times of food scarcity.
* Ermine: These small weasels are highly efficient predators and can easily catch ground squirrels.
* Wolverine: Although they prefer larger prey, wolverines will opportunistically hunt ground squirrels.
Birds:
* Snowy owls: These powerful owls are specialized hunters of rodents, including ground squirrels.
* Gyrfalcon: Gyrfalcons are also adept at catching ground squirrels, using their speed and agility.
* Rough-legged hawks: These hawks are known to hunt ground squirrels, particularly during the summer months.
Other:
* Bears: Although bears primarily feed on berries and fish, they may occasionally hunt ground squirrels.
* Humans: In some areas, humans may hunt ground squirrels for food or fur.
It's important to note that the specific predators of Arctic ground squirrels vary depending on the location and time of year. For example, snowy owls are more prevalent in winter when ground squirrels are hibernating, while foxes and wolverines are more likely to prey on them during the summer months when they are active.
