Habitat
This subspecies primarily inhabits coastal forests, meadows, and rocky areas on Haida Gwaii in British Columbia, Canada. It prefers dense vegetation for cover and is often found near streams or wetlands. Geographic isolation limits its range to these islands.
Diet
The Queen Charlotte Islands stoat mainly eats small rodents like voles and mice, as well as birds, rabbits, and occasionally eggs or insects. It is an active hunter that employs a stalking and pouncing technique, often feeding at dawn or dusk. This carnivorous behavior helps control rodent populations in its ecosystem.
Behavior
Queen Charlotte Islands stoats are solitary and territorial, marking their areas with scent to deter rivals. They are primarily nocturnal or crepuscular, exhibiting agile and curious behaviors like climbing trees or swimming to pursue prey. During winter, they may travel long distances in search of food, but they generally avoid direct confrontation.
Conservation Status
The stoat (Mustela erminea) as a species is listed as Least Concern by the IUCN, but the Queen Charlotte Islands subspecies (haidarum) is not separately assessed and faces threats from habitat loss due to logging and invasive species. Population trends are declining, making local conservation efforts important for its isolated range.
