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.

Asian Brown Flycatcher

Muscicapa dauurica

A small, understated muscicapid flycatcher known for its upright posture and large-eyed appearance. It is a common sight in Asian woodlands, often seen perched motionless before darting after insects.

What it sounds like

A thin, high-pitched 'tzee' or metallic 'chi-chup' call; its song is a faint, rambling series of warbles and trills.

Field notes

Distinguished by a conspicuous white eye-ring and a broad bill with a pale orange or yellow base on the lower mandible.
Highly migratory, breeding in the eastern Palearctic from Siberia to Japan and wintering across tropical South and Southeast Asia.
Exhibits a 'sallying' hunting technique, where it flies from an exposed perch to snatch insects in mid-air before returning to the same spot.
The species is sexually monomorphic, meaning males and females are virtually identical in their drab grayish-brown plumage.
Often identified by its relatively long wings and short primary projection compared to other similar-looking Muscicapa species.

Habitat

Open broadleaf forests, woodland edges, parks, gardens, and mangroves during the wintering season.

Range

Breeds in Eastern Asia and Siberia; winters in India, Sri Lanka, Indochina, and Indonesia.
