My mystery warbler is back, singing away. I recorded the song last year, and have attached the file that has 4 good repetitions. Always 6-7 notes, zoo-zoo-zoo-
My guess is Black-throated Blue, which we do have in our area, and does nest here we believe (1300 ft elevation, Adirondack foothills). I hear the call all summer long.
Habitat: Coniferous 2nd growth forest, hemlock, white pine, norway spruce. Some deciduous: black cherry, yellow birch.
I would appreciate the opinions of readers. Thanks in advance.
