Bat week is an annual international
celebration of the role of bats in nature. Step outside around dusk and take a
few moments to look for bats in your neighborhood.
Iowa is home
to nine bat species: little brown bat, big brown bat, red bat, hoary bat, silver-haired
bat, Indiana bat (federally endangered species), evening bat, eastern
pipistrelle, and northern myotis.
Try this fun
game from the KinderNature
website to help children understand how bats use echolocation to catch
insects.
Bats Eat Bugs
Have all
players stand in a large circle. Choose one child to be the bat and place a
blindfold over her eyes. Choose five other children to be bugs inside the
circle.
The bat moves
around inside the circle calling out “Bug, bug, where are you?” The bugs call
back “Here, here!” as if the sound was bouncing off of them back to the bat.
When the bat hears the echo, she attempts to catch the bugs by tagging them.
The bat may call as many times as she wishes. Each time the bugs must answer.
Fun Bat Facts
- A small bat eats between 1,000 and 2,000 small insects every night. Bats use sonar to find dinner when it’s pitch black out. Bats make noises, which bounce off the bugs and back to the bats’ ears, where the sound is picked up by the bats’ specialized hearing.
- Bats are our only flying mammals in the state.
- One of Iowa’s few true hibernators, bats hibernate all winter until there are insects to chow down on again.
- Within three weeks of being born, young bats are taking flight. They grow quickly, being full-grown in about a month after birth. Young bats take off for their own roosts once they’re weaned.
- Bats hang upside down because it allows them to roost in places where predators can’t reach them. It also allows them to get into the air faster by falling to achieve flight.
