I just installed BirdNET, and it's pretty amazing! Must be online to connect to AI servers in Germany. Even "guessing" at a poor sample, it's mostly right on! Thick woods hereabouts, full of songs, but hard to see. Eventually got eyes on a Wilson's Warbler, not yet the Townsend's. Confirmed Chestnut-backed Chickadee, Dark-eyed Junco, Spotted Towhee, Northern Flicker, Common Raven. It reported several Orange-crowned Warblers, which I haven't spotted, but I know them from here, as I do the Pacific Flycatcher. It even reported a Brown Creeper, which I never heard, but, sure enough, there he was, creeping up a cedar tree!
A whole new game! Still hoping to see a Townsend's, but I'm confident they are up there in the canopy, 75-100 feet up.
