Yukon population estimate
Shrews live a fast and furious life entirely focused on consuming enough food to fuel their high metabolism. It is active both day and night throughout the year eating its weight in food every day. They are insectivores with teeth specially designed for grasping and cutting its prey. Shrews of the sorex family are some of the only terrestrial mammals known to use echolocation. They emit calls and listen for returning echoes, which lets them locate other objects in the area.
Insects including pupae, eggs, larvae and dormant adults.
