Bristol Nature Telemetry Ltd

Privacy-first, real-time bird and bat acoustic sensing for increasing engagement with the natural world: hello@naturetelemetry.com

We provide acoustic monitoring devices that classify birds and bats on-device to show local people what's happening in their open spaces in real time. We are privacy-first - no acoustic data leaves the device, ideal for populated areas such as public parks and open spaces where engagement with locals is essential, and privacy is essential.

Real-time bird and bat detection and classification

We use on-device machine learning to classify birds and bats from recordings, so no data leaves the device. We use LoRaWAN to transmit the data in near-real time and can collate, filter and display it for viewing in an appropriate format and location.

Community Engagement

We've been working with Bristol Wireless to set up LoraWAN gateways on tower blocks in Bristol for community sensor projects, starting with a Nature Listening workshop at KWMC).

Along with KWMC and Bristol Wireless, we are involved in Building Bristol's Backyard Biophilia, funded by University of Bristol's UKRI-funded Creative AI for Social Good programme, which will help us understand what form devices should be in when in public places.

Data Wrangling

Working with ecologists, we've been figuring out how to wrangle the data into a useful format for validation and reporting.

Immersive Installations

"Spring Simulator" is a one-person-at-a-time immersive umbrella-based surround-sound installation playing bird or bat songs, which featured at EMFCamp 2026 as part of the batcave.
