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.

Berylline Hummingbird

Saucerottia beryllina

The Berylline Hummingbird is a medium-sized, iridescent green hummingbird distinguished by its striking cinnamon-colored wings and tail. It is a primarily Mexican species known for its bold, territorial behavior in montane woodlands.

What it sounds like

A sharp, buzzy, and mechanical series of 'skee-zher' or 'sir-rit' notes delivered in a rapid, jerky rhythm.

Field notes

Displays a unique 'rufous' coloration on the primary wing feathers and tail that contrasts sharply with its emerald green body.
Highly aggressive at nectar sources, frequently dominating other hummingbird species at feeders and flowering shrubs.
While a year-round resident of Mexico, it is a regular summer visitor and occasional breeder in the 'sky islands' of southeastern Arizona.
Nests are typically constructed of plant down and spider silk, meticulously decorated with lichen for camouflage on low-hanging branches.
Commonly engages in 'hawking,' where it flies out from a perch to capture small insects in mid-air to supplement its nectar diet.

Habitat

Oak-pine woodlands, montane forests, and riparian canyons.

Range

Widespread through Mexico and northern Central America, with seasonal range extension into the southwestern United States.
