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.

Field notes

It is strictly endemic to Cozumel Island and occasionally nearby Isla Mujeres off the Yucatán Peninsula.
Males feature a significantly longer and more deeply forked tail compared to the shorter, notched tail of females.
The species was formerly classified in the genus Chlorostilbon before being moved to Cynanthus based on genetic data.
Its bill is notably straight and reddish with a distinct black tip, a key field mark for identification.
Despite its small size, it is a primary pollinator for several endemic plant species within its island restricted range.

Habitat

Tropical deciduous forest, coastal scrub, and mature gardens.

Range

Cozumel Island, Mexico.
