feeding about our campsite. The male has
frequently sung from a young fir tip scarcely
ten feet directly above the nest, also from the brush
all about it, and when hopping on the ground between
or thru the bushes. The rim of the nest is 360 mm.
above a mat of yellow pine needles; the nest itself
is ensconced among the leaning stems of a
rather sparse ceanothus integerrimus. It is a
large structure, of much coarse pine and other
twigs externally, and lined with shredded bark.
There are two young, about 3 days old I think,
helpless and downy rather than feathery. The old
female is very solicitous, coming within 6 feet
of us when at the nest; but the male shows
little concern, and sings volubly immediately
we leave, from within 20 feet of the nest.
Mountain Chickadee's nest, with young, in woodpecker
hole opening on under side of a leaning stub a foot
in diameter and some 15 feet long. Entrance just
my height from the ground - 5 ft., 7 in.; diameter of
entrance, 44 mm. - so probably was made by a
White-headed Woodpecker. Site open, surrounded by dry
ceanothus slope; some very small yellow pines nearby,
also two yellow pine stumps, sawed off so long ago
they are rotting, cleft. The old chickadees come
with food freely, altho I am only about 15 feet
away under a bush on the dry (?) hill side. Each
bird dives directly into the hole, as it arrives,
