Habitat
This species primarily inhabits moist forests, grasslands, and shrublands in the mountainous regions of the Caucasus. It prefers areas with dense undergrowth and proximity to streams or wetlands for cover and food sources. Geographically, it is endemic to the Caucasus, spanning parts of Georgia, Russia, Armenia, and Azerbaijan.
Diet
The Caucasian pygmy shrew mainly feeds on insects, spiders, earthworms, and other small invertebrates. It hunts actively using its keen sense of smell, often foraging in leaf litter or soil during both day and night. Due to its high metabolic rate, it must consume food equivalent to its body weight daily to survive.
Behavior
Caucasian pygmy shrews are solitary and territorial, defending small home ranges with scent markings. They are primarily nocturnal, spending the day in burrows or under debris, and exhibit rapid, darting movements while foraging. Notable behaviors include a high-pitched vocalization for communication and an aggressive response to intruders.
Conservation Status
The IUCN Red List classifies the Caucasian pygmy shrew as Least Concern, with a stable population trend. Major threats include habitat loss from deforestation and agricultural activities.
