Habitat
This shrew inhabits arid and semi-arid regions of the southwestern United States and northern Mexico, including deserts, grasslands, and scrublands. It prefers areas with loose soil for burrowing and is often found near rocks or vegetation for cover. These environments provide ample invertebrates for food.
Diet
The large-eared gray shrew primarily eats insects such as beetles, ants, and crickets, as well as spiders and other small invertebrates. It forages actively at night, using its keen senses to locate prey in leaf litter or soil. Feeding frequently is necessary due to its high metabolic rate.
Behavior
This shrew is solitary and nocturnal, spending the day in burrows and emerging at night to forage. It exhibits territorial behavior, marking areas with scent and avoiding direct confrontations. Notable behaviors include rapid movements and a high activity level to meet its energy needs.
Conservation Status
The IUCN status of the large-eared gray shrew is Least Concern, with a stable population trend. Major threats include habitat loss from urban development, but it is not currently facing significant declines.
