At Rancho San Antonio I heard my FOS monotonously-singing Orange-crowned Warbler.  It was close enough that I was tempted to take a picture of its shaking body.

Later, on the one-way trails, I was treated to the continuous "Johnny one-note" song of a Hutton's vireo.  He never stopped, even when other hikers passed by me, but I never located him.
