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 exceptionally territorial and will aggressively defend nectar sources from much larger birds and insects.
Commonly seen in urban environments, it is the most ubiquitous hummingbird species across Trinidad and Tobago.
The female typically lays two tiny white eggs in a cup-shaped nest made of plant fibers and spider silk, camouflaged with lichen.
It engages in 'hawking' behavior, flycatching small insects in mid-air to supplement its nectar-rich diet.
While primarily green, its namesake copper-colored rump is most visible when the bird is in flight or under direct sunlight.

Habitat

Open woodlands, gardens, parks, and cultivated areas with flowering plants.

Range

Trinidad, Tobago, and northeastern Venezuela.
