Cornelius’ Corner: “The Little Brown Bat”

Little Brown Bat

Hi friends- Cornelius’ friend, the little brown bat is here. Thanks for coming back to read more of our blog series! Today I will be sharing fun facts about my diet. Stay tuned for more posts!

As a bat, I use echolocation when I go hunting for food. It’s a really cool technique. I use reflected sound waves to determine the location of objects around me. Then I listen real closely to discover where my prey is by listening to the sound echoes. I am able to alter the duration, pattern and frequency range of my calls, which helps me differentiate between prey and stationary objects.

I eat a wide variety of insects, including midges, mayflies and caddisflies, plus gnats, beetles, wasps, moths and crane flies. I search for my meals in fields, woods and in areas close to the water, such as along stream banks or over ponds and lakes. In the park, I like to forage above the Frog Pond and Trout Ponds!

Each night I need to eat at least half of my body weight to keep up with my very high metabolism. Little Brown Bats like me typically weigh between 4 and 8 grams, which is the equivalent of 1 to 2 grapes. I can eat about 1,000 small insects within an hour! Female little brown bats that are nursing have to eat even more – about 110% percent of their body weight. That equals around 4,500 insects each night!


Thanks for reading my blog! Stay tuned for more posts. See you at the Grist Mill!
