On: BirdNET-Pi: Automated, locally run bird sound identification and tracking

[smackay]

It would be very cool to have network of these listening to calls while birds are migrating at night. With a large enough network you'd get an amazing way to visualise large scale movements which are generally completely invisible. Wiring up the eastern seaboard around Massachusetts, southern Spain, the vast steppes around the Caspian Sea or pretty much anywhere else would be incredible.

BirdNET isn't tuned particularly for nocturnal flight calls (NFCs). But a network of listening stations with automated identification exists and is improving rapidly. Vesper (https://github.com/HaroldMills/Vesper) is one open-source project. Terra (https://www.kickstarter.com/projects/theterraproject/listen-...) is also related.

Believe it or not, we already have a technology for nighttime bird migration monitoring: weather radar.

Radar for Europe: https://eurobirdportal.org/

This is made to compare two birds and their migration pattern over the last year.

Birds seem to have different radar signatures so that there is a different pattern for each bird.

I can't find a single place, on that site, which mentions radar.

Instead, it talks about data from partners, sources, etc., and even mentions some of them as manual counts, overlapping, etc.

It just looks radar-ish, but is not.

Very cool! I wonder how unique the signatures are and whether this can scale to smaller flocks.
