Spring Song & Whispers sung one May morning at Peck's Lake [Arizona]. His performance this day included several minutes of loud singing and several of his "whisper songs".
I caught this Plumbeus (formerly Solitary) Vireo's (Vireo plumbeus) act in Sedona, Arizona in early October, 1997. This was the Rocky Mountain form. He was, just as he should be, in the Piñons and Junipers, and he was, just as he should be, alone! That's a Gambel's Quail you hear worrying during the first half of the sample.
