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.

today seen at least 7 different sets of mole "ridges"--which are here only lines of cracked earth; that is, a slight raising of the wet, packed surface merely fractures it. No wonder one can see no sign of moles when the sand and gravel is dry and loose. It would appear that the "rare" San Pedro Martir mole is not so rare, after all. Only one must look for it just after a rain. 6424 Sciurus (female sign) 150g. 313x122x53x16. Shot from pine 50ft. up. 6425 Pigmy Nuthatch (male sign) ad. 12.7g. Shot from pine on dry ridge. 6426 Slender-billed Nuthatch (male sign) ad. 16.7g. Shot from pine 25ft. up. 6427 Canyon Wren (male sign) im. 11.1g. Shot on ledge of granite outcrop. Oct. 7 6428 Microtus (female sign) 70.6g. 192x55x25x12. In sawgrass. 6429 Microtus (female sign) 44g. 168x45x24x10. In sweet clover at edge of stream. Both in gorge to which cattle could not reach. Discarded: 3 Peromyscus truei, 2 (female sign), 1 (male sign); two under edges of boulders, 1 under manzanita; all on dry gravelly ground of mesa. 6430 Lutescent Warbler (male sign) ad. 7.9g. Shot in willow by stream. 6431 Lincoln Sparrow (female sign) im. 14.9g. Shot in willow by stream. 6432 Junco (male sign) ad. 18.5g. Shot from top of boulder. 6433 Intermediate Sparrow (male sign) ad. 23.8g. In open clovery place by creek; absence of one leg doubtless due to encounter with mouse trap! Barometer reading on camp table 23.15 inches; day perfectly clear, cool in shade.

6456 Slender-billed Nuthatch (female sign) ad. 16.8g. Shot from bole of pine. 6457 Sierra (?) Junco (male sign) im. 18.3g. Shot on ground among salvia bushes. This was the only junco of this form seen so far; alone. 6458 Junco (male sign) ad. 18.3g. bill, pinkish white; iris sepia; shot in willow. 6459 Junco (male sign) im. 18.8g. bill, pinkish white; iris sepia; shot in willow with the last. 6460 Bluebird (female sign) im. 27.3g. Shot in pine. 6461 Bluebird (male sign) im. 28.2. Shot in pine. 6462 Bluebird (male sign) im. 29.9. Shot in pine. 6463 Bluebird (male sign) ad. 28.5g. Shot in pine. 6464 Cabanis Woodpecker (female sign) 46.7g. Shot in pine. 6465 Cabanis Woodpecker (female sign) 53.6g. Shot in pine. This morning I went off to the south about 2 miles up a draw and into some hills where there was considerable of the oak growth that looked good for birds from a distance. I saw nothing there, however, not common around camp; only a few Mountain Chickadees, one small company of Bluebirds, two Cabanis Woodpeckers, and the ever-present Pigmy Nuthatches. All of these were in or about pines, not in the oaks at all. Oh yes, -- two Ravens flew over. Most of the birds put up today, and listed above, I shot within half a mile of camp. Of the bluebirds, pigmy nuthatches, and chickadees, there is a seemingly exhaustless supply right around us. Saw a Tanager today, in the cascara thickets, where I shot one the other day. Heard the

doubtless hardly covered with dirt as they go. I suppose they find the insects in the leaf-mold under the thickets here and there. Lamb and I both have "modified" Macabee gofer (sic) traps set all the time for the moles, but this species is so small that an individual goes thru and thru (sic) a trap without springing it, or if sprung, without nipping(?) him. 7:00 p.m. -- Barometer = 23.20 inches Sky partly overcast, but northwest wind blowing cold. 6466 Merriam Chipmunk (male sign) 56g. 226x98x34x14.

Barometer tonight, 23.10 inches; clear and cold - an inch of ice on water bucket this morning. Ground Squirrels (beecheyi) are still out in numbers. I suppose they may hibernate here, but no signs of it yet. Chipmunks simply swarm on certain bushy slopes - 6 in sight at once, scampering over boulders, or over the ground from bush to bush. They have all the notes of ordinary merriami - the hollow "bock", etc. I have seen "sign" of Jack Rabbit, but not one of the animals. This is evidently not a rabbit year. Saw two Ruby-crowned Kinglets in the willows today; one Tanager in cascara; at least 4 Solitaires, whose interests center around the cascara thickets, as do those of the Bluebirds. 6493 Slender-billed Nuthatch (female symbol) ad. 16.3g. Shot from pine bole. 6494 Pine Siskin (female symbol) ad. 15.2g. Shot from up in pine. Oct. 12 Trap-line played out; only 18 Peromyscus truei in trap under manzanita - discarded. 6495 Olive-backed thrush (female symbol) im. 29.1g. In rat-trap under manzanita. 6496 Cañon Wren (female symbol) ad. 10.4g. Shot from boulder, one up a pile. 6497 San Lucas Flycatcher (male symbol) im. 8.9g. Shot in willow thicket, from perch 5 feet up. The only individual tyrannid of any sort whatsoever seen here this fall. 6498Slender-billed Nuthatch (male symbol) ad. 16.8g. Shot in pine. 6499Pigmy Nuthatch (female symbol) ad. 11.1g. Shot from pine. 6500Sierra (?) Junco (female symbol) im. 15.3g. Alone; shot on ground among salvia bushes;
