R.J.Raiff 1957 Journal Dec 29 2 mi. W Rye's Peak, 7000 ft, Pine Mtn, Ventura Co, Calif. calling intermittently all morning. They were very shy and glimpsed only rarely. Finally after missing me and stalking this me for several minutes I collected one out of some young pines right in the campground. Mountain Chickadees were present and calling intermittently. They appeared to keep moving fairly constantly and seemed to be singles, keeping mainly to the higher parts of the yellow pines & White Firs. Twittering from higher parts of trees among foliage were birds assumed to be Pygmy Nuthatches. As I was con- centrating on White-headed Woodpeckers I did not examine them closely at this time but later in the morning (11:30 AM) identified them in the same area, Feeding in groups, very voraciously, mostly high in the trees. White-headed Woodpeckers were active in the early morning. Their "chinks" were heard occasionally occasionally punctuated by trills given as they flew. They seemed to be feeding mainly on the bare trunks part way up live or dead yellow Pines. I collected one q from the trunk of a live pine and a Jt & q from the trunk of a dead one. All were about 20-30 feet above the ground. In a similar situation a Nuttall Woodpecker was collected from the trunk of a Yellow Pine. Also seen was a Red-tailed Hawk flying high over the summit of the ridge in the early morning. At about 9 AM we drove east about 1 mile to the edge of the pines where the "Chorro Grande" trail reaches the top of the ridge from the Sespe Canyon far below. After searching the summit area - it is treeless and covered
