Overview

The bicolored shrew or bicoloured white-toothed shrew is a species of mammal in the family Soricidae. It is found in eastern, central and southern Europe and in western Asia. It is a nocturnal species and feeds on insects and other small creatures. Several litters of young are born during the warmer months of the year in a nest of dry grasses in a concealed location.

The Bicolored Shrew faces significant population declines primarily due to habitat loss and fragmentation from agricultural expansion and urbanization across its European range. Climate change and intensive farming practices that reduce invertebrate prey availability further threaten remaining populations.
