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.

Birdsong field guide

Brown Creeper

Certhia americana

A small, cryptically colored songbird specialized for foraging on tree trunks, recognized by its unique habit of spiraling upward while probing bark for insects.

What it sounds like

Very high-pitched, thin 'tsee' calls and a delicate, tinkling song often transcribed as 'trees, beautiful trees'.

Field notes

It builds a unique hammock-shaped nest tucked securely behind loose flaps of peeling tree bark.
The bird uses its stiff, pointed tail feathers as a structural prop to support itself against vertical surfaces, similar to a woodpecker.
It follows a distinct foraging pattern, starting at the base of a tree and spiraling upward before flying down to the bottom of the next tree.
Its plumage is a perfect example of crypsis, mimicking the texture and color of tree bark so effectively it becomes nearly invisible when stationary.
It possesses a specialized, slender, decurved bill designed specifically for extracting spiders and insects from narrow bark crevices.

Habitat

Mature coniferous and mixed-deciduous forests with large-diameter trees and abundant loose bark.

Range

Widespread throughout North America, ranging from Alaska and Canada across the United States to the highlands of Mexico.
