I was very surprised to find a large number of these along this trail. From here spreading downhill (left) and forward along the trail, first on the left then on both sides, I stopped counting at 75 as it was getting hard to count. There were at the very least 150, if not 200 along the stretch of trail I walked (total walked, 1mile each way from College parking lot).
Not a very clear pic but had a brown head and crest, black wing bars. Kent Lake
