Can you help? Know someone else in Tasmania who can?

Through the CallTrackers project, anyone in Tasmania can help monitor bats, by putting up one of the project recorders.

The project uses some incredible software that can instantly pick which bat species is which, from recorded calls. However, it’s far from foolproof yet.

To improve the software, CallTrackers HQ needs to record more calls of bats which have been identified in advance.

Roosts are the answer! At a roost, the species of bat can be identified and their calls can then be recorded as they head off in the evenings. The Bookend Trust has been awarded funding from the Wettenhall Environment Trust to do this over the coming spring and summer.

Do you know of a roost? Have you heard some ‘fairy whispers of the forest’. or spotted a stream of bats whooshing from a tree hollow? Or noticed some glittering little poos in your the roof space? Or perhaps you’ve spotted them somewhere else entirely. Please tell us more by completing our ‘Report a roost’ survey!


How do I know it’s a bat roost?

Hearing chittering (at sunset & sunrise mostly), seeing shiny mouse-like poos on walls or on the ground.

Who’s identifying the bats?

Super-chiropterologist Dr Lisa Cawthen!

What will you do with the roost?

We’ll talk to you; maybe come and check if the bats are there at the moment and which species they are. If it suits our needs well and you’re happy, we may set up equipment in spring/summer to record the bats as they come out of the roost.

Where can I find out more information about Tasmania’s bats?

You can read more information on Tasmania’s bats on the Department of Natural Resources and Environment Tasmania’s website.
