I was out of town when this thread started – thanks to whomever got it going. My five have a (mainly) East of the Cascades bent. 1. The song of the Canyon Wren breaking the silence here in canyon country. 2. A Townsend’s Solitaire singing on a clear, crisp winter’s day. 3. A cattail marsh chorus at dusk with Yellow-headed Blackbirds, American Bitterns, Soras, Virginia Rails, various ducks and Marsh Wrens contributing to the symphony of sounds. 4. A pair of duetting Boreal Owls high up Tumalo Mountain. 5. The haunting calls of an Iiwi coming from a fog-shrouded Hawaiian kapuka. Honorable mention goes to any Catharus thrush song.
