Station
A low-cost, solar-powered listening device. It runs the species model itself and sends only events.
- ESP32-S3 with an I2S MEMS microphone
- LoRa radio for remote terrain
- Solar panel and battery
- On-device species model
An open acoustic monitoring system. Solar stations listen to birds, rangers see everything on one map.
Reserves are vast. People in the field are few. Birds do not wait for the next survey.
Many birds fly and call after dark, when nobody is there to hear.
Waves of birds pass in days. Rare visits miss them.
A huge territory and few people in the field.
A microphone listens around the clock. And it is cheap.
It listens.
It understands.
It tells you.
How it works
A MEMS microphone on a solar-powered ESP32-S3 station records day and night.
A small model names the species on the device itself. The raw audio stays there.
LoRa carries the species, the time and the confidence. A tiny message, not a recording.
A gateway in the reserve office receives the events. No internet needed.
Rangers get an event feed, a map of stations and Telegram alerts.
A station in the field and a platform in the office.
A low-cost, solar-powered listening device. It runs the species model itself and sends only events.
One screen for the whole reserve. Works offline with a local gateway.
Event feed with an audio clip to verify
Data and code will be published, so any reserve can repeat the setup.
A live preview with demo data. Real events will look like this.

Architecture
Four sources write to the database. The dashboard reads only from it.
Sound from the stations. The core of the project.
Water and vegetation from open satellite imagery.
Photos and headcounts to calibrate the sound index.
Partners' GPS tracks and observations.
observations: species, time, place
environment layers: water, vegetation
Know what lives on your territory around the clock. Get alerts about rare species and threats. Keep your own data.
Labeled recordings from the Kazakh steppe, BirdNET and Perch tested on local species, export in Darwin Core.
Alerts in Telegram, a map of stations, nothing complicated to set up.
A wetland of international importance in the Kazakh steppe.
Part of the World Heritage site Saryarka, Steppe and Lakes of Northern Kazakhstan (2008).
A wetland of international importance: the Tengiz and Korgalzhyn lake system.
Lake Tengiz is described as the northernmost flamingo nesting site in the world.

Events from every reserve flow into one national dashboard in Astana. More reserves join the same system.
Validation
BirdNET and Perch on existing recordings give a first accuracy table by species.
Korgalzhyn recordings labeled with the reserve's ornithologist, so the accuracy is verified.
We test on other sites and other dates, not on random clips of one recording.
A reference recorder runs alongside. Wind and water are tested separately. False alarms are counted per hour.
The reserve agrees to the installation and names an advising ornithologist.
First accuracy table for BirdNET and Perch.
Collection and labeling, split by site and date.
Fine-tuning, quantization, event feed and Telegram alerts on one station.
Power draw, LoRa range, comparison with a reference recorder.
Results for the RKNP and ISEF science competitions.
In parallel: satellite analysis of water and vegetation.
Next: a second reserve with different terrain, to test whether the model transfers.
We are looking for a pilot reserve, an ornithologist, and mentors in audio ML and remote sensing.
