Protecting and enhancing the natural values of Salt Spring Island and its surrounding waters


Yuma Myotis

Yuma Myotis

Myotis yumanensis 

This common Salt Spring bat can appear similar to the Little Brown Myotis and the two species may occupy the same roosts. The Yuma bat is distinguished from the Little Brown Myotis by the higher call frequency of the former, and a preference for foraging low over water as opposed to navigating more complex environments. This bat species is frequently found roosting in human-made structures, such as barns, out-buildings, and attics. These bats can huddle together in nursery colonies to raise the temperature to above 30 degrees Celsius, promoting growth and survival of their young. Photo credit. Daniel Neal
