A federated social platform for citizen bird science
Log your bird sightings, follow other birders, and connect with people across Mastodon and the Fediverse. Your data stays yours — forever.
Recent sightings
Built on open protocols
The Fediverse is a network of independent servers that talk to each other using an open standard called ActivityPub — the same protocol that powers Mastodon, Pixelfed, and millions of accounts worldwide.
When you join Aviary, you get a handle like @you@aviary.app. People on Mastodon can follow you. You can follow them. No one company controls the network.
If Aviary ever shuts down, your followers stay yours — move to any other ActivityPub server and keep your community.
Mastodon
Mastodon users can follow your Aviary profile and see your sightings in their home feed.
Pixelfed
Photo-first ActivityPub platform — your bird photos connect across the Fediverse.
Other Aviary servers
Any self-hosted Aviary instance federates with yours automatically.
Why Aviary
Log sightings in the field with no signal. Drafts save to your device and sync when you're back online.
Export everything as JSON or eBird-compatible CSV at any time. No proprietary formats, no lock-in.
Your exact GPS coordinates never leave the database. Only a ~10 km fuzzy region is shared publicly.
One toggle hides all images in feeds — for slow connections, older devices, or just saving data.
Record a bird call and let AI identify the species. Lowers the barrier for beginners.
Run your own Aviary instance for your community. Open source, Docker-ready, no vendor lock-in.
Free, open, and part of the Fediverse.
