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.

Bermuda Saw-whet Owl

Aegolius gradyi

The Bermuda Saw-whet Owl was a small, extinct strigid endemic to Bermuda, distinguished from its mainland relatives by its smaller size and sedentary lifestyle.

What it sounds like

Unknown; presumably a series of rhythmic, high-pitched whistles similar to the 'skiew' or 'toot' calls of other Aegolius species.

Field notes

It was formally described as a distinct species in 2012 based on subfossil remains recovered from Quaternary cave deposits.
The species exhibited island dwarfism, being significantly smaller in skeletal dimensions than the Northern Saw-whet Owl (Aegolius acadicus).
Its extinction likely occurred in the 17th century following the arrival of European settlers and invasive predators like cats and rats.
Morphological analysis of its wing bones suggests it was non-migratory, unlike its highly mobile North American counterparts.
It likely specialized in preying upon endemic lizards and invertebrates, as there were no native terrestrial mammals on Bermuda.

Habitat

Dense maritime forests dominated by Bermuda Cedar (Juniperus bermudiana) and Bermuda Palmetto (Sabal bermudana).

Range

Endemic to the archipelago of Bermuda in the North Atlantic.
