In a social media landscape dotted with false information and AI-generated images, a bat bum aimed at ‘brightening the feed’ might seem unreal.
They do exist, just not as we see them, explained Julianna Laposa-Wilde, Southern Vancouver Island Bat Program coordinator with Habitat Aquisition Trust.
“They don’t have bum cheeks but they do have glute muscles,” Laposa-Wilde explained.
While a fun little fact, and they look similar in some situations, the bat bottoms are not comparable to the gluteus in humans.
“Humans' are developed for walking or running, which obviously bats don’t do. Their bodies are built for flight,” she said.
The light-boned bats are chiroptera, which translates to “hand wing” – describing their essentially elongated fingers covered by a thin layer of skin to form wings. It allows for super agility and acrobatics in flight.
“They’re the only mammals that are capable of true flight,” Laposa-Wilde said.
Another image that routinely appears on social media feeds suggests the exhaustion a bat might feel hanging upside down for ages upon end. A human would need to contract muscles and quickly tire, but the bat's anatomy creates hooks, and the critters don’t need to even think about the act.
“When they’re hibernating or sleeping, they have tendons in their feet that allow them to hang,” Laposa-Wilde explained. “The weight of their body pulls on that tendon and that’s how they can hang there.
Anatomy is just one intriguing aspect of the critters currently slipping out of hibernation in Greater Victoria and across B.C.
In other parts of the world, Laposa-Wilde explained, they pollinate plants – drinking nectar and moving from plant to plant such as banana, mango and agave.
“You can thank bats for tequila,” she said.
Locally, bats are insectivores – dinner includes the universally despised mosquito – devouring more than 1,000 a night. Plus the nitrogen-rich guano makes a great fertilizer.
With more than 1,400 species across the globe, B.C. boasts a diverse species count with 15 of Canada’s 18 species – nine of those are on Vancouver Island. Right now, they’re emerging from hibernation in caves, trees and other crevices, with reports rolling in to Habitat Acquisition Trust of the creatures hanging about in some unusual places.
“We tell people it’s common right now, they’re leaving hibernation and making their way to summer roost sites,” Laposa-Wilde said. That said, the agency is taking reports of sick or dead bats now through May 31 as it monitors for white nose syndrome. The fungus, devastating bat populations across North America, affects bats during hibernation. The white powder on their face and bodies causes them to wake during hibernation, using up valuable energy stores.
While white nose doesn’t affect humans, it’s still important not to come into contact with bats for a variety of reasons – with rabies likely top-of-mind.
Again, it's a case of context when finding information online; the deadly virus that does impact humans is present in less than one per cent of bats. Many online statistics, however, will show 13 to 15 per cent – based on testing of only dead bats.
“Bats can have rabies, which is lower than one per cent, but because rabies is so serious, it’s important to treat every bat like they could have it,” Laposa-Wilde said. “If you come into contact with a bat, or suspect you’ve come in with contact with a bat, it’s important to get help … that being said, bats don’t want to mess with people so they will avoid you at all costs.”
