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.

Chilean Hawk

Astur chilensis

The Chilean Hawk is a medium-sized forest raptor endemic to the southern Andes, recognized by its dark slate-grey upperparts and distinct rufous-barred underparts.

What it sounds like

A rapid, high-pitched series of staccato 'ke-ke-ke-ke' notes, often becoming more frantic near the nest.

Field notes

While formerly classified as a subspecies of the Bicolored Hawk, it is now widely recognized as a distinct species due to geographic isolation and morphological differences.
It is a specialized avian predator, with birds accounting for over 90% of its diet, often caught through high-speed maneuvers in dense foliage.
The species is highly dependent on old-growth Nothofagus (Southern Beech) forests for nesting and hunting.
It exhibits seasonal altitudinal migration, moving from high-altitude Andean forests to lower coastal valleys during the winter months.
Nesting pairs build large stick platforms high in the canopy, usually hidden by epiphytes or dense leaf cover to avoid detection.

Habitat

Mature temperate rainforests and deciduous Nothofagus forests.

Range

Southern South America, specifically the Andean regions of Chile and Argentina from Valparaíso to Tierra del Fuego.
