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

Despite its name, molecular studies indicate it is a member of the tanager family (Thraupidae) rather than a true finch.
It is one of the few bird species in its range to exhibit sexual monomorphism, where males and females share the same striking plumage.
Their nests are unusual dome-shaped structures with side entrances, typically built in low-lying shrubs or dense thickets.
While primarily a fruit-eater, it is known to consume snails and large insects to supplement its protein intake.
The species was formerly classified in the genus Loxigilla before being moved to Melopyrrha based on phylogenetic evidence.

Habitat

Thick undergrowth in diverse environments including montane forests, mangroves, and shaded coffee plantations.

Range

Endemic to the archipelago of Puerto Rico.
