How accurate is Birdsong's bird identifier?

It runs Google's Perch, a research-grade acoustic model covering nearly 15,000 species. When a call is ambiguous, we say so honestly and let you record a second clip to confirm, rather than guessing.

Is my recording stored?

No. Your audio is used to identify the bird in the moment and isn't saved to our servers. The birds you confirm are kept as cards in your own field journal; the recordings themselves are not.

Is the bird identifier free?

Yes — identify birds every day for free, no account required. Birdsong Pro ($3.99/mo or $39.99/yr) unlocks unlimited IDs, full field guides, your growing collection, and shareable Field Report cards.

Do I need an account or internet to identify a bird?

You'll need a connection to identify, since the AI runs in the cloud. No account is needed to try it — sign in with Google or email to save your field journal and sync it across devices.

The Red-necked Stint is a diminutive migratory shorebird famous for its vibrant brick-red throat and neck during the breeding season. It is a flagship species of the East Asian-Australasian Flyway.

What it sounds like

A sharp, thin 'chit' or 'stit', and a buzzy, rhythmic trill during aerial breeding displays.

Field notes

It is one of the world's smallest sandpipers, often weighing as little as 25 grams.
The species performs a massive annual migration of up to 25,000 kilometers between the Arctic and Australasia.
They are colloquially known as 'peeps' due to their tiny size and high-pitched vocalizations.
Unlike the closely related Little Stint, it typically lacks a distinct pale 'V' on its mantle during the breeding season.
During the non-breeding season, it loses its red coloring and becomes a cryptic grey-brown to blend into mudflats.

Habitat

Breeds on upland Arctic tundra; winters on coastal mudflats, estuaries, saltpans, and sandy beaches.

Range

Breeds in Northeast Siberia and Western Alaska; winters in Southeast Asia, Australia, and New Zealand.
