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.

Sporophila castaneiventris

Field notes

Exhibits strong sexual dimorphism, with females being nondescript olive-brown and lacking the male's chestnut plumage.
Primarily granivorous, they use their stout, conical bills to efficiently extract seeds from various grasses and sedges.
While often found in pairs, they frequently join large mixed-species foraging flocks in open clearings during the non-breeding season.
The species is considered highly nomadic in certain regions, moving according to the seasonal seeding patterns of local grasses.
Unlike many rarer Sporophila species, it has adapted well to human-disturbed landscapes such as pastures and agricultural edges.

Habitat

Open grassy areas, marshes, riverbanks, and shrubby clearings in tropical lowlands.

Range

The Amazon Basin of South America, spanning Brazil, Colombia, Peru, Ecuador, Bolivia, and the Guianas.
