Habitat
This shrew primarily inhabits high-altitude grasslands, páramo ecosystems, and montane forests in the Andes of Ecuador, typically between 2,000 and 4,000 meters above sea level. It prefers moist, cool areas with dense vegetation for cover and foraging. These habitats provide ample insects and invertebrates for its diet.
Diet
The Ecuadoran small-eared shrew mainly eats insects such as beetles and ants, along with earthworms and other small invertebrates. It forages actively at night using its sensitive snout to detect prey, consuming food frequently to sustain its high metabolic rate. Feeding occurs in leaf litter or soil, where it digs or probes for items.
Behavior
This shrew is solitary and territorial, marking its area with scent glands to avoid encounters with others. It is primarily nocturnal, emerging at night to forage actively in search of food, and spends the day hidden in burrows or under vegetation. They exhibit high energy levels due to their rapid metabolism, often moving quickly and erratically.
Conservation Status
The IUCN Red List classifies the Ecuadoran small-eared shrew as Least Concern, with a stable population trend, though habitat destruction from agriculture and climate change poses potential threats.
