Hi, At the parking area at 8am I had 2 Sage Thrasher, then on the way up the gravel road a FOS Northern Shrike. Had a few Bushtits and White Crowned Sparrows , but no warbler species along the Eagle Trail.Two hours later on the way down I watched a passing flock of 70 plus Mountain Bluebirds. Good Oct.
