Spotlight on a Species at Risk - Little Brown Myotis
This edition’s focus on a Species at Risk is all about the Little Brown Myotis, which is a species of dłı̨ą k'et'à (bat). It is medium-sized, with light brown to dark brown-black fur across its body. The fur on its underside is typically lighter in colour. The female dłı̨ą k'et'à are somewhat bigger than the males, and typically have only one baby (typically referred to as a pup), in a year. This little dłı̨ą k'et'à can eat as much as 600 insects the size of a mosquito in an hour, and hunts in many habitats, including near water.
The Little Brown Myotis is listed as follows:
NWT List of Species at Risk: Special Concern
Federal Species at Risk Act List: Endangered
Like all dłı̨ą k'et'à, the myotis is susceptible to white-nose syndrome, which is a fungal disease that kills dłı̨ą k'et'à, and has been decimating populations across Canada. Thus far, white-nose syndrome has not arrived in the NWT; however, it could eventually spread here. Dłı̨ą k'et'à also face other risks including human activities in and around where they hibernate, such as caves and mines, or buildings which are being removed or renovated. If dłı̨ą k'et'à are hibernating inside, they may be unable to get out causing a large number to die. It’s important for their survival that we ensure human activities do not impact their habitat, food sources, and migratory patterns. To learn more about how to protect dłı̨ą k'et'à of all species in the NWT, check out Got Bats, a great resources created by the GNWT on how to manage dłı̨ą k'et'à found in buildings.
