From carrying diseases to being the source of COVID, bats have gotten a bad rap.
“I think it is just popular opinion because of all the advertising around bats being spooky thieves.” said Jamie Racalla, an animal care supervisor with John Ball Zoo. “When in truth, half of them are pollinators, take care of those pesky bugs like mosquitoes, and don’t really carry all those diseases.”
It is why such exhibits as the Grand Rapids Public Museum’s current “Bats: Masters of the Night” are so important, Racalla said, because it helps to dispel some of the myths around these very difficult to study and often misunderstood creatures.
“We really don’t know that much about bats,” said Racalla, who recently participated in a study on bats in Michigan hosted by the Detroit Zoo. “Think about when they are out, at night, which makes them difficult to study because it has to be dark.”
For a while, researchers would study bats during the day while they slept in bat houses or when they hibernated during the winter. Unfortunately, White-Nose Syndrome developed among North American bats, which is a fungus call Pseudogymnoascus destructans, that invades and ingests the skin of hibernating bats, causing them to wake up more frequently in the winter and use up their limited fat reserves. First found in North America in 2006, it is estimated that by 2012 more than 6.7 million bats in North America have died from the disease.
To help reduce the spread of the fungus, researchers have discontinued visiting bats in their homes, but instead are using sonar to help track the bat population in the United States, This past summer, Racalla drove around parts of Greater Grand Rapids using equipment to hear bat calls which helped determine what type of bats could be in the area.
Through her research, Racalla said she found several bat types such as the little brown bat, eastern red bat, big brown bat, and the silver-haired bat, all of which eat insects such as mosquitoes, beetles, flies, ants, and spiders.
Through the Grand Rapids Public Museum’s exhibit, residents can make their own discoveries about the creatures of the night. While there are blood-sucking bats — vampire bats live in Central and South America — a majority of the bats are gentle and much like the bats found in Michigan, beneficial to the ecosystem.
Visitors can learn more about diet and flight of various bats around the world (The only place without bats are Arctic, Antarctic and a few isolated Oceanic islands). The exhibit includes lifelike models, multi-sensory interactive displays and environmentally lifelike settings. There also is a hands-on display showcasing the evening activities of bats, such as echolocation (sonar ability). In a demonstration of echolocation, visitors can use a joystick to maneuver a bat model in search of food using a laser to simulate sonar. In a visit to a bat nursery, visitors learn how caring bat mothers are by using sound to help the mother bat find her baby.
“I personally can’t wait to see the exhibit,” Racalla said. “I hope people go and it helps them have a greater understanding of just how misunderstood and unique they are.”
Also the importance of preservation of the bat community. Because of the White-Nosed Syndrome, most Michigan bat species are considered threatened or endangered. Because of state and federal productions, it is illegal to kill certain species of bats, according to the USDA Forest Service.
“Bats: Masters of the Night” will be up through January 2022 at the Grand Rapids Public Museum, 272 Pearl St. NW. Hours are 9 a.m. – 5 p.m.Monday – Friday and 10 a.m. – 5 p.m. Saturday and Sunday. “The Bats: Masters of the Night” is included in the museum’s general admission. General admission for Kent County residents is $5/adults, $3/seniors, and free/children 17 & under. For more information
