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.

Green Mango

Anthracothorax viridis

Field notes

It is the only mango species where both sexes possess nearly identical shimmering green underparts.
The species is highly territorial, frequently defending nectar sources from other hummingbirds and even larger birds.
Its long, slightly decurved bill is perfectly adapted for extracting nectar from tubular flowers like those of the Heliconia.
While primarily nectarivorous, it frequently engages in 'hawking' to capture small insects in mid-air for protein.
The nest is a tiny cup made of plant fibers and spider webs, typically decorated with lichen for camouflage.

Habitat

Montane forests, shade-grown coffee plantations, and interior garden edges.

Range

Endemic to the main island of Puerto Rico.
