Bats are amazing creatures--an important and beneficial part of our ecosystem. Because
they are often misunderstood, they are often mistreated. In the past 25 years, Indiana
bats have declined by about 50 percent. As a result, in 1967, the United States government
classified Indiana bats as an endangered species. Cedar Creek resident and bat
rehabilitator Bob Walton says: “56% of America’s bats are either endangered
or candidates for the [endangered] list.”
Common in the Cedar Creek area are the little brown bat, Myotis lucifugus
; the big brown
bat, Eptesicus fuscus; and the silver haired bat, Lasionycteris noctivagans. The Indiana
bat, Myotis sodalis
, is a medium-sized, dull gray bat, head and body 1.5 to 2 inches,
weighing 1/4 of an ounce and differentiated from other bat species by feet size and
length of toe hairs. Indiana bats live an average of five to 10 years (some as long as
14 years), roosting under the peeling bark of dead and dying trees and hibernating
primarily in caves and mines.
Most bats are very difficult to distinguish from their cousins. Although fewer than 1%
have rabies, you should never handle bats barehanded.
Bats deserve our respect and protection for many reasons.
Picture yourself at the
end of a hot summer day...you walk outside to relax, to enjoy the cooler evening air...
and...mosquitoes attack. Instead of retreating inside or spraying yourself with insect
repellent, you could be protected by a nearby colony of bats.
All bats feed on night-flying insects, including moths, beetles, mosquitoes, and midges.
Bats consume vast quantities of insects that not only pester humans but also damage
agriculture. A single bat will eat up to 3,000 insects in one evening (and many insects
avoid areas where they hear bats). As primary predators of night-flying insects, bats
play a key role in the balance of nature.
Five ways you can support bats:
- Help conserve natural bat habitat by preserving wooded areas. Do not remove trees with
loose, scrappy bark such as old maples, oaks, shagbark hickories.
- Garden organically, or limit insecticide use. (Bats will eat contaminated insects and
can get sick or die due to the buildup of fat-soluble pesticides in their bodies.)
- Decrease artificial nighttime lighting, or attach motion detectors so lights aren’t on
all night. Artificial lights disturb some bats’ normal foraging patterns.
- To support bats, plant more native [instead of exotic] plants to encourage many more
species of insects for the bats to eat.
- Remove invasive plants to keep nearby woodlands healthy.
