I'm definitely impressed with the sound ID. One time there was a cacophony of birds singing outside my house at varying distances, and the app was able to identify 6 different bird species within 30 seconds. All 6 suggestions seemed reasonable to me.
I’m really impressed about how well the sound ID works for birds doing mimicry.
We had a brown thrasher stringing together a long series of mimicked calls that got labeled correctly as a brown thrasher.
I don’t even know how you’d approach the ML for that seeing how unique each song is to each bird
We sometimes joke it's hallucinating when it detects something unexpected, but often it was being accurate. I saw my first ever male Blackburnian Warbler a couple weeks ago after Merlin picked it up.
