Habitat
This shrew inhabits moist montane forests, grasslands, and agricultural areas in central and southern Mexico, often at elevations from 1,000 to 3,000 meters. It prefers areas with dense vegetation and leaf litter for cover and foraging.
Diet
It primarily feeds on insects such as beetles, ants, and spiders, as well as earthworms and other small invertebrates. Feeding occurs mainly at night, with the shrew using its keen sense of smell to locate prey in leaf litter or soil.
Behavior
This shrew is solitary and nocturnal, spending its active hours foraging for food in leaf litter with quick, darting movements. It is highly territorial, marking areas with scent and avoiding interactions with others except during mating. Its high metabolic rate requires constant eating, leading to frequent activity bursts.
Conservation Status
The IUCN classifies the Grizzled Mexican small-eared shrew as Least Concern, with a stable population trend, though habitat loss from deforestation poses a potential threat.
