Habitat
This species inhabits tropical and subtropical forests in Central America, including Costa Rica and Panama. They prefer moist, dense vegetation such as rainforests and cloud forests, often at elevations up to 2,000 meters, where they can find ample trees for shelter and foraging.
Diet
Alston's mouse opossum primarily eats insects like beetles and crickets, as well as fruits, nectar, and small vertebrates such as lizards or frogs. They forage nocturnally, using their agile movements to hunt or gather food in trees and on the ground. This omnivorous diet allows them to adapt to seasonal food availability.
Behavior
Alston's mouse opossum is solitary and nocturnal, spending most of its time climbing in trees to avoid ground predators. It exhibits territorial behavior by marking areas with scent glands and is generally quiet, though it may hiss or play dead when threatened. They are agile and curious, often exploring new areas in search of food.
Conservation Status
The IUCN classifies Alston's mouse opossum as Least Concern, with a stable population trend due to its wide distribution. Major threats include habitat destruction from deforestation and agriculture.
