Habitat
This shrew inhabits moist montane forests, grasslands, and agricultural edges in Central America, primarily in the highlands of Costa Rica and western Panama. It prefers areas with dense undergrowth and leaf litter for cover, often at elevations between 1,000 and 3,000 meters. These environments provide ample moisture and invertebrate prey.
Diet
The Central American least shrew primarily eats insects such as beetles, ants, and earthworms, along with other small invertebrates like spiders and snails. It forages actively day and night due to its high metabolic rate, using its sensitive snout to detect prey in leaf litter and soil. Feeding occurs frequently, sometimes every few hours, to sustain its energy demands.
Behavior
This shrew is solitary and territorial, marking its area with scent and aggressively defending it from intruders. It is primarily nocturnal, spending the day in burrows or under logs and emerging to forage at night with quick, darting movements. They exhibit high activity levels due to their rapid metabolism and are known for their vocalizations, including high-pitched squeaks during interactions.
Conservation Status
The IUCN Red List classifies Cryptotis orophila as Least Concern, with a stable population trend, though habitat loss from deforestation poses a potential threat in its range.
