slopes of Inskip Hill); Calif. Woodpecker; Nuttall Woodpecker; Calif. Purple Finch (very common and in full song here in the black oaks); Linnet (equally common and in full song); Western Tanager (one in full song, as I write); Cassins Vireo and Western Warbling Vireo (equally in evidence); Wood Pewee (common); Ash-Throated Flycatcher ( "buckaroo" song heard early in the morning from slopes of Inskip Hill; Black-Throated Gray Warbler (several singing males); Lutescent Warbler (one singing male) Western Lark Sparrow (several); Western Chipping sparrow (common and singing); Green-backed Goldfinch (singing birds almost continually within hearing); Wren-tit (heard song from bushy slopes of Inskip Hill; Valley Quail (sentinel call of male in distance); Plain Tit (one pair, in black oaks); Slender-billed Nuthatch (very common); Bullock Oriole (one heard); Morning Dove (several have flown past); The "stream" right here is now dry - all the water taken out for the ranches around Payne Creek P.O. But down below here a few rods a narrow canyon begins, cut down thru the lava cap, and there, there are potholes with water, the source, apparently, for the birds of these woods. Along the ravine are luxurious golden oaks, densely blooming syringia (Philadelphus), ash trees, etc. Up in the rocky walls are bushes of Cercis and Rhus Trilobata.

tree up from the ground 60 feet or more. Nothing more was heard from her. As in the other case, I could hear the muffled "pumping" of a mile in the distance, probably nearer than it sounded.

We got back to camp at 6pm.

8:15 a.m -- Wright Flycatcher's nest, the one found four days ago and which Dixon has been photographing. The 3rd and 4th eggs were laid on successive lays, so probably an "egg a day"; the 4th egg was laid within a few minutes of 10:45 a.m.; the bird was apparently sitting continuously from at least the time when the 2nd egg was deposited. Nest in nearly upright clump of stems and twigs of Ceanothus cordulatus; rim of nest 950 mm. above ground; tallest sprigs of ceanothus 490 mm. directly above rim. Nest site in middle of rather open clump about 15 feet across, part of a general growth of this chaparral on a gently south-facing hill-slope; 4 big yellow pines and a white fir within a 100-foot radius. Nest itself rather easily seen from head-height in most directions. Male "sings" high in nearby yellow pines. Female always leaves by ducking down and off thru the chaparral on side away from intruder, not heretofore reappearing. Female shot, and nest and eggs (1/4) taken. Eggs show no incubation.

One old male California Purple Finch flew down onto the ground in camp this morning at 7; possibly some of my "Cassins Purple Finches" have been "California's". Yet the songs are appreciably different.
