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.

Thick-billed Vireo

Vireo crassirostris

The Thick-billed Vireo is a small Caribbean songbird characterized by its stout beak and yellowish-olive plumage, closely resembling the White-eyed Vireo but with a heavier bill and darker eyes. It is a secretive dweller of dense subtropical thickets and scrubland.

What it sounds like

A variable, energetic series of 5-7 whistled notes, often sounding like 'quick-pick-per-wee-o-chick,' more jumbled than the White-eyed Vireo.

Field notes

It is primarily endemic to the Bahamas, Turks and Caicos, and the Cayman Islands.
Unlike the White-eyed Vireo, adults typically have dark brownish-red or amber irises rather than bright white ones.
The species is a rare but regular vagrant to Southern Florida, often appearing in the Keys or the Everglades.
Its nest is a deep, pendulous cup suspended from a tree fork, intricately woven with spiderwebs and plant fibers.
Its diet is seasonally opportunistic, consisting of insects during the summer and shifting heavily toward small fruits and berries in the winter.

Habitat

Dense scrub, coastal coppice, mangroves, and thick secondary growth.

Range

Bahamas, Turks and Caicos, Cayman Islands, and occasionally South Florida.
