All -
Yesterday I took my nearly-annual hike to Thunder Lake in Wild Basin. This hike takes me past Calypso Cascades, the home of at least one Pacific Wren over the last two summers, so I knew to listen. As I approached the cascades, I clearly heard the song of a stub-tailed wren. Eventually, I located the songster as well as a second bird. Both appear to be Pacific Wrens. The wren was singing actively on my way up as well as on my way down - he doesn't seem particularly bothered by the crowds. He does, however, vanish for periods of time as he moves up/down the creek.

Good birding,
