Facts, limitations & testing
Record nearby birds and compare suggested matches with reference calls. Treat a match as a suggestion to verify, not a confirmed identification; sound coverage varies by species and region.
Requires iOS 18 or later. Cornell’s guidance requires email confirmation after a five-day grace period; saving a personal sighting list uses a Cornell account.
Sound identification can work offline. Download regional information beforehand for offline photos and details.
Our view
A reason to use your phone for a closer look at a familiar walk. This is an established rediscovery, not a new-release claim.
