Habitat
This shrew inhabits high-elevation cloud forests and paramo grasslands in the Andes of Peru, typically between 2,000 and 4,000 meters. It prefers moist, forested areas with dense undergrowth and leaf litter for foraging and shelter. These habitats provide the cool, humid conditions it needs to thrive.
Diet
The Peruvian small-eared shrew primarily eats insects, earthworms, and other small invertebrates like spiders and beetles. It forages actively on the ground, using its sensitive snout to detect prey, and feeds frequently due to its high metabolism, often at night or during twilight hours.
Behavior
This shrew is solitary and territorial, marking its area with scent and avoiding others of its kind except during mating. It is primarily nocturnal, spending the day in burrows or under logs, and exhibits rapid, darting movements while foraging. Due to its high metabolic rate, it is constantly active and consumes food almost continuously.
Conservation Status
The IUCN status of the Peruvian small-eared shrew is Data Deficient due to limited research, but habitat loss from deforestation and agriculture poses a potential threat. Population trends are unknown, but it may be stable in remote Andean regions.
