Habitat
Ornate shrews primarily inhabit moist environments such as forests, grasslands, and shrublands in western North America, including coastal regions from California to Oregon. They prefer areas with dense vegetation and proximity to water sources like streams or wetlands, which provide cover and prey. These habitats offer the necessary humidity to support their high metabolic needs.
Diet
Ornate shrews mainly feed on insects, earthworms, spiders, and other small invertebrates, which they hunt actively. They have a high metabolic rate and eat frequently, often consuming up to their body weight in food daily, with feeding occurring both day and night. Their feeding behavior involves probing the soil and leaf litter with their sensitive snouts.
Behavior
Ornate shrews are solitary and territorial animals that mark their home ranges with scent to avoid encounters with others. They are primarily nocturnal, emerging at night to forage and explore, though they may be active during the day in cooler conditions. These shrews exhibit rapid movements and vocalizations, such as high-pitched squeaks, to communicate or defend territory, and they often create intricate networks of tunnels in the undergrowth.
Conservation Status
The ornate shrew is classified as Least Concern by the IUCN, with a stable population trend across its range. Major threats include habitat loss from urbanization and agriculture, but it remains widespread and adaptable.
