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
