Habitat
This species primarily inhabits tropical and subtropical regions of South America, including Brazil, Argentina, and Paraguay. It thrives in a variety of environments such as forests, savannas, and even urban areas with vegetation for cover. They prefer areas with dense undergrowth for shelter and foraging.
Diet
The White-eared opossum is omnivorous, feeding on fruits, insects, small vertebrates like rodents and birds, and carrion. It forages opportunistically at night, using its keen sense of smell to locate food. This behavior allows it to adapt to various food sources depending on seasonal availability.
Behavior
White-eared opossums are primarily nocturnal and solitary, spending their nights foraging or climbing trees. They exhibit a 'playing dead' defense mechanism when threatened, remaining motionless to avoid predators. They are territorial, marking areas with scent glands, and are adept climbers due to their prehensile tails.
Conservation Status
The IUCN status of the White-eared opossum is Least Concern, with a stable population trend. Major threats include habitat destruction from deforestation and roadkill from vehicle collisions.
