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 the only hummingbird species known to migrate north along the Gulf Coast for the winter after breeding in South Texas.
Both males and females possess nearly identical plumage, featuring a bright red bill with a dark tip.
The species is notoriously aggressive, frequently chasing much larger birds away from its preferred nectar sources.
Nests are often constructed using spider silk and lichen, typically placed on low-hanging branches of ebony or citrus trees.
It is a primary pollinator for several native subtropical plants, including Turk's Cap and Anacahuita.

Habitat

Subtropical woodlands, thickets, citrus groves, and residential gardens with flowering plants.

Range

Lower Rio Grande Valley of Texas, eastern Mexico, and the Yucatán Peninsula, with wintering ranges extending along the US Gulf Coast.
