Several times this winter I've across a flock, 25+ birds, of yellow-rumped warblers acting like a flock of bushtits. When I panned the flock they've all been Myrtles, not an Audubon form within the flock. The flock crosses the trail, then moves on en mass. I've never seen so many Myrtles here on the west coast, usually an individual here and there. Sheep Camp Trail is a service road between Cañada Road and the rest area on Hwy 280.
