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.

Birdsong field guide

Ross's Gull

Rhodostethia rosea

A small, ethereal gull of the High Arctic, renowned for the delicate pink bloom on its plumage and its distinctive wedge-shaped tail.

What it sounds like

High-pitched, melodic 'kwa-kwa-kwa' or 'pe-weet' notes, sounding more delicate and tern-like than typical gulls.

Field notes

Breeding adults develop a soft pink flush on the breast and belly, derived from carotenoid pigments in their crustacean-rich diet.
It features a narrow, black ring around the neck during the breeding season which disappears during the winter months.
Unlike the square or rounded tails of most gulls, this species possesses a distinctively pointed, wedge-shaped tail.
The bird was named after British explorer Sir James Clark Ross, who collected the first specimen in 1823 during an Arctic expedition.
While most gulls migrate south, many Ross's Gulls migrate further north into the Arctic Ocean to winter at the edge of the pack ice.

Habitat

Marshy tundra and river deltas for breeding; pelagic zones and the edges of pack ice during winter.

Range

Circumpolar Arctic, with primary breeding grounds in Northeastern Siberia and smaller colonies in Canada and Greenland.
