What is CallTrackers?
What is CallTrackers?
CallTrackers is the Bookend Trust’s third and newest NatureTrackers project, aimed at using sound recorders to find and monitor noisy but elusive species. Our initial focus is on bats and the threatened Australasian Bittern, both of which have distinctive calls.
The project will introduce you to acoustic wildlife monitoring. Choose a location and deploy a recorder, then upload the resulting data. We’ll send you information on which species have been identified thanks to a data pipeline provided by the British Trust for Ornithology. You’ll learn about which species live in your area, their biology, behaviour and conservation needs.

How to book a square.
How to book a square.
Reserve a survey square via the on-line booking map and book your detector from one of our distributions centres. (It's much easier to do this using a web browser on a computer than on a phone.)
Squares are colour-coded with those in blue our highest priority as they contain wetlands with high conservation value.
If you're unsure where the wetland is within your square, the CallTrackers Squares Map is here to help. See the Site Access Guide for information.

Do you need land access permission?
Do you need land access permission?
Please note that you may need permission from the landholder to access your chosen location, see our Site Access Guide before booking your square.
Note that you will need to sign up for a British Trust for Ornithology (BTO) account if you're booking a square for the first time. You will be guided through this process once you've selected your square. The BTO host our square and equipment booking system.
Reserving a recorder kit
Reserving a recorder kit
You can reserve a recorder kit for 11 days at a time. Please allow time for an 8 night deployment and make sure the kit is returned on or before the due date.
Library staff will receive an email a couple of days before a booking starts, so they should be expecting you. When you get there, let them know who you are and why you're there, and they should give you the recorder kit comprising a small case and a bundle of poles.
Once you've familiarised yourself with the equipment and procedures, detailed in The CallTrackers User's Guide you're all ready to go!
