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.

Basileuterus belli

A vibrant New World warbler of Middle American highlands, easily identified by its rich chestnut crown and bold yellow supercilium. It is a restless inhabitant of dense forest understories, often seen flitting through low foliage.

What it sounds like

A high-pitched, thin 'tseee-tseee-tseee' followed by an accelerating, twittering trill.

Field notes

Possesses a distinctive chestnut-colored crown bordered by black lateral stripes and a bright yellow eyebrow.
Unlike many migratory warblers, this species is sexually monomorphic, meaning males and females look nearly identical.
Is a highly active forager that frequently flicks its wings and tail while searching for insects in thick vegetation.
Often serves as a nuclear species in mixed-species foraging flocks within its montane habitat.
Constructs a domed 'oven' nest on the ground or a steep bank, typically hidden by moss and leaf litter.

Habitat

Humid montane forests, oak-pine woodlands, and dense secondary growth with thick understory.

Range

Highlands of Mexico, south through Guatemala, El Salvador, and Honduras.
