Ever Heard of a Microbat?

By Susan P Smith | Project Manager

The 2023-2024 flying fox season has been a long one. We worked hard to get as many adult bats returned to the wild before we shut the release aviary at the rehabilitation centre at Lane Cove National Park for the winter. Many interested people are unaware that the only flying fox adult release aviary in NSW is located at the Lane Cove National Park. We moved roughly 150+ adult bats through the process of rescue to release back to the wild. There are a few who are viable but not ready for release. These flying foxes come into care with very dedicated and experienced carers who “overwinter the adults” so they can be ready for release the following season.

Overwintering is common in the bat world. If one comes into care but doesn’t have enough rehabilitation time before the aviary closes for winter, then we want to give them every chance to return to the wild. Experienced carers will take the bats into their home and overwinter them using very large wire dog crates. May sound small but it is the top of the line luxury for these megabats. They hang and sleep the entire day. If they want to flap their wings or open them wide, there is room in the cage. At dusk, they are fed a smorgasbord of cubed apples, pears and melons or grapes. We also throw a little high protein supplement in with the fruit. They are content and overwinter well with this method.

This season I am overwintering microbats which are the tiny creatures you might see in a cave or in a tree hollow. They are very different from the megabats in that they do not require the kilos of fruit the larger bats need and they make relatively no mess to clean up. Megabats need their cages cleaned at least every second day. Microbats are fun and a great change from their larger friends. I have five Large Forest Bats in my care, all female and most likely all pregnant. This species of micros weighs between 6-9 grams. Re read that, it is the correct weight.

When in care, the micros are kept in a large canvas dog crate with reinforced screens around the mesh “windows” and there is a heat source at one end of the crate. This allows the micros to “chose their temperature.” They mostly stay on the opposite side of the heat in torpor – the bat equivalent to hibernation. When it is time to feed, I’ll rouse each one from torpor and place them in a large pouch on top of a heating pad. They will remain there for about 30 minutes to adjust their body temperature to eat so so they don’t waste even more energy eating. Food for the micros in care comes in the form of mealworms and a blended food we make up for them. Micros can eat 100% of their body weight which can be equivalent to 8-12 mealworms.

Eventually these little ladies will be transported to a microbat aviary to spend a few weeks to strengthen their flight muscles. Microbat flight aviaries are round rather than large rectangle cages for megabats. Once they have their flight muscles in tip top shape, they will be transported to a release carer who will release them exactly where they were found. Microbats are very territorial and must make it back to their colony when released. Each colony, regardless of species, has a unique language only used within that colony. When they are rescued, detailed directions to the rescue site will come with the micro when it is placed with a carer. They are released in the late evening. When they are removed from their pouch and resting on our uplifted hands, the chattering will begin. It’s almost as if they are saying:

“Hey Jackie, are you there?”

“Hey Susie, welcome back! We’re here and ready for you to come home!

And then, just like that, they take off and fly to their colony. Your job is done and now it’s time to get ready for the megabats!
