General Information

The Buena Vista Lake shrew (Sorex ornatus relictus) is one of nine subspecies of ornate shrew (Sorex ornatus) known to occur in California. Ornate shrews are primarily insectivorous (insect-eating) mammals that are the approximate size of a mouse. Shrews make up the family Soricidae. Shrews have a long snout, tiny bead-like eyes, ears that are concealed, or nearly concealed, by soft fur, and five toes on each foot. They are active day or night. When they are not sleeping, they are searching for food, namely insects and other small invertebrates. Shrews eat more than their own weight each day to avoid starvation and maintain their body weight at high rates of metabolism. The specific feeding and foraging habits of the Buena Vista Lake shrew are unknown. The Buena Vista Lake shrew's back is predominantly black with a buffy-brown speckling pattern, its sides are more buffy-brown than the upper surface, and its underside is smoke-gray. The tail is faintly bicolor and blackens toward the end both above and below. The Buena Vista Lake shrew grows to around 4 inches in total length, including a tail of about 1.5 inch. Adults weigh 0.14-0.27 ounce.
