Habitat
This shrew inhabits moist, tropical forests and grasslands in Central America, particularly in countries like Costa Rica and Panama. It prefers areas with dense undergrowth and leaf litter for cover, and can also be found in disturbed habitats like agricultural fields. Elevation ranges from sea level up to about 2000 meters in mountainous regions.
Diet
The scaly-footed small-eared shrew primarily feeds on insects such as beetles, ants, and earthworms, which it hunts actively in leaf litter and soil. It supplements its diet with small spiders and other invertebrates, typically foraging at night to avoid predators. Feeding behavior involves quick, darting movements to capture prey.
Behavior
This shrew is primarily nocturnal and solitary, spending its active hours foraging for food in underground tunnels or under leaf litter. It exhibits territorial behavior, marking areas with scent glands to deter others of its species. Notable behaviors include high metabolic rates leading to constant eating and rapid movements to evade threats.
Conservation Status
The IUCN Red List classifies the scaly-footed small-eared shrew as Least Concern, with a stable population trend due to its wide distribution. Major threats include habitat loss from deforestation and agricultural expansion in Central America.
