Habitat
The Harenna shrew is endemic to the Bale Mountains in southeastern Ethiopia, inhabiting high-altitude moist forests, grasslands, and bamboo thickets above 3,000 meters. It prefers areas with dense undergrowth and proximity to water sources, avoiding open or arid terrains.
Diet
This shrew primarily feeds on insects such as beetles, ants, and earthworms, as well as other invertebrates like spiders and small snails. It forages actively at night, using its keen sense of smell to locate prey on the forest floor. Feeding behavior involves quick, darting movements to capture and consume food.
Behavior
The Harenna shrew is primarily nocturnal, spending its days hidden in burrows or under logs and emerging at night to forage solitarily. It exhibits territorial behavior, marking areas with scent and avoiding direct interactions with others of its species. Notable behaviors include rapid, zigzagging movements and a high metabolic rate that requires constant feeding.
Conservation Status
The IUCN lists the Harenna shrew as Endangered due to habitat loss from deforestation and agricultural expansion in the Bale Mountains. Population trends are declining, with major threats including climate change and human encroachment.
