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.

Anianiau

Magumma parva

The Anianiau is the smallest extant Hawaiian honeycreeper, distinguished by its vibrant yellow-gold plumage and specialized nectar-feeding bill.

What it sounds like

A high-pitched, thin 'tew' or 'psit' contact call and a rapid, musical song consisting of a sweet, liquid trill.

Field notes

It is the smallest of all living Hawaiian honeycreepers, reaching a total body length of only about 10 centimeters.
Unlike many other honeycreeper species, both males and females possess bright yellow feathers, though the male's plumage is generally more intense.
Genetic and morphological studies led to its reclassification into the monotypic genus Magumma, separating it from the Hemignathus genus.
While primarily nectarivorous, the Anianiau frequently gleans small arthropods and spiders from the foliage of the forest canopy.
Its population is currently restricted to high-elevation refugia above 600 meters to avoid the threat of avian malaria carried by mosquitoes at lower altitudes.

Habitat

High-elevation montane wet and mesic forests dominated by ʻōhiʻa lehua and koa trees.

Range

Endemic to the island of Kauaʻi, Hawaii.
