Habitat
This subspecies primarily inhabits mixed forests, grasslands, and riparian areas around the Western Great Lakes region, such as Michigan and Wisconsin. They prefer areas with dense underbrush for hunting and shelter, and are adaptable to both rural and suburban environments as long as prey is abundant. Terrain includes hilly or flat lands near water sources.
Diet
Western Great Lakes stoats mainly consume small rodents like voles and mice, as well as rabbits, birds, and their eggs. They are agile hunters that employ a stalking and pouncing technique, often active at dawn and dusk to catch prey. In lean times, they may eat insects or carrion to supplement their diet.
Behavior
Stoats are solitary and territorial, marking their ranges with scent glands and fiercely defending against intruders. They are crepuscular, most active during twilight hours, and exhibit playful, acrobatic movements while hunting. These animals are known for their curiosity and ability to climb trees or swim to pursue prey.
Conservation Status
The stoat is classified as Least Concern by the IUCN, with a stable population trend in North America. Major threats include habitat fragmentation from urban development and road accidents, but this subspecies is not currently at risk of extinction.
