NATURE CLICKS #412 - LITTLE BROWN BAT


Little Brown Bat (Myotis Lucifugus)

When you live in the woods it is inevitable that ones in a while a critter enters the house without a particular invitation. I have helped numerous birds over the years to reobtain their freedom after they couldn’t find the open door again through which they had entered the house. 

Knocked over decorations on a window sill told us already a few days ago that something is in the house that shouldn’t be there, but we couldn’t find any suspect. Yesterday I finally found this Little Brown Bat sitting on the floor, looking pretty powerless. I put a leather glove over my hand and a minute later the bat was in the grass behind the house. Bats are nocturnal and don’t usually fly during the day. The poor critter tried to reach a dark spot under the rack for the garden hose and moved on the ground while I tried to take a picture of it. After an hour it was gone and is hopefully in a better and safer spot.

Here are some facts I have found at different sources on the web: The Little Brown Bat (Myotis Lucifugus) is the most common bat in North America and can be found even in Alaska. As already mentioned, these bats are nocturnal and sleep or groom during the day. A single bat can eat up to 1000 mosquitos during only one hour! Bats are not aggressive by nature and unless you are threatening them they won't act aggressively toward you. Most bats are quite timid and prefer to avoid people.

Little Brown Bats are now at a higher threat due to white-nose syndrome (WNS) in eastern North America. White-nose syndrome is caused by the fungus, Pseudogymnoascus destructans, which affects bats during hibernation. WNS is estimated to have killed more than 5.5 million bats in the Northeast and Canada. In some sites, 90 to 100 percent of bats have died (U.S. Fish and Wildlife Services, 2015). Many states have made special considerations with respect to the disease, including listing them as a sensitive or protected species. Canada has listed them as an endangered species. It is estimated that 94% of the population in the eastern half of the country has died over the last few years from WNS, and the disease is moving westward at a rate that may see them extirpated within as little as 12 years.
