This afternoon I recorded a warbler hiding in dense brush at Neary Lagoon. Merlin kept identifying it as Northern Yellow Warbler, but the spectrogram appears to me to be much closer to the example of American Redstart from Peterson's Field Guide to Bird Sounds of Western North America. Four to six melodic notes in the first phrase, followed by a single buzzy note at the end - see attached image.
When I got home, I normalized the volume and put it into Birdnet, but all it detected was House Finch and a fainter Wilson's Warbler that was also singing. When I put only one isolated instance of the target bird song into Birdnet, it identified American Redstart, but with only 16% confidence.
The bird was singing constantly on the Neary Lagoon trail just past the playground at the end of Chestnut Street: 36.96325749975487, -122.0280721909303.
