Noctaves
While we sleep, one of nature's greatest mass movements happens right above us — billions of birds moving through the dark, hidden from view.
But birds passing through the dark leave a unique acoustic signature. While their flights are invisible to our eyes, Sonaves devices listen closely—capturing the distinct audio signals that reveal exactly the flights overhead.
Our work follows two complementary approaches.
We deploy and operate our own network of devices — the Noctaves Network — and share insights on the blog.
We also work with organisations and individuals who run devices or a network of devices. From research institutes to individual birdwatchers. And schools, nature guides, eco-lodges and anyone else fascinated by the mysteries of nocturnal migration.
We're just getting started...
Last April, we deployed our first Sonaves unit on the island of Antikythira in close collaboration with the Hellenic Ornithological Society (HOS) at their historic Antikythira Bird Observatory (ABO).
Antikythira is a remote, wind-swept island positioned directly between the southern Peloponnese and western Crete. Its location along the Eastern Mediterranean flyway makes it a vital, high-traffic highway for birds during their northward spring migration. HOS has pioneered ornithological research on this rugged outpost since 1997.
The Sonaves unit records continuously on a 24/7 schedule, capturing both daytime activity as well as nocturnal migration. Sifting through hundreds of hours of raw audio is a challenge — but Sonaves AI technology does most of the heavy lifting, automatically isolating distinct bird calls from the background to reveal the sounds we are looking for.
