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.

Cuban Martin

Progne cryptoleuca

The Cuban Martin is a large, glossy-plumaged swallow endemic to Cuba during the breeding season, closely resembling the Purple Martin but distinguished by specific plumage markers.

What it sounds like

A series of rich, liquid gurgles and low-pitched, musical trills similar to 'pweet-pweet' or 'choo-choo'.

Field notes

Adult males possess a diagnostic white patch on the lower belly and vent, which distinguishes them from the entirely dark-vented Purple Martin.
It is a highly social species that typically nests in colonies, often utilizing old woodpecker holes or crevices in urban buildings.
The species is a migratory breeder, arriving in Cuba around February and departing by late August or September.
While its breeding range is well-defined, its exact wintering grounds in South America remain one of the great mysteries of Caribbean ornithology.
As an aerial insectivore, it performs most of its foraging at high altitudes, capturing a wide variety of flying insects mid-air.

Habitat

Open areas, coastal regions, and urban centers with suitable nesting cavities.

Range

Breeds exclusively in Cuba and the Isla de la Juventud; migrates south for the winter.
