Habitat
This shrew primarily inhabits moist tropical forests, grasslands, and agricultural edges in Central America, from Mexico to Panama. It prefers areas with dense undergrowth, leaf litter, and moist soil for burrowing and foraging, often at elevations up to 2,000 meters. These environments provide cover from predators and ample food sources.
Diet
The Tropical small-eared shrew mainly eats insects, earthworms, and other small invertebrates like spiders and centipedes. It forages actively at night using its acute sense of smell, and consumes food frequently due to its high metabolic rate. Feeding occurs in short bursts to maintain energy levels.
Behavior
These shrews are solitary and territorial, defending small home ranges with scent markings. They are primarily nocturnal, emerging at night to forage rapidly and avoid daytime predators. Notable behaviors include high-pitched vocalizations for communication and burrowing into soil or leaf litter for shelter.
Conservation Status
The IUCN classifies the Tropical small-eared shrew as Least Concern due to its wide distribution and presumed large population. Major threats include habitat loss from deforestation and agriculture, but it remains adaptable in human-modified landscapes.
