(one, perching at dead tops of sycamores); Song Sparrow (1, near seepage); Rufous-crowned Sparrow ( one shot and another heard); Fox Sparrow (2); Spotted Towhee (2); Brown towhee (1); Ruby-crowned Kinglet (1); Audubon Warbler (fully 20); Valley Quail (2 large coveys); Calif. Thrasher (one singing fitfully). I also visited a hillside patch of "dry bog" -- clayey open ground grown to foxtail grass in season. Here I saw two Pipits, heard a Horned Lark, and saw a company of Bluebirds, two of the males being of the solidly blue-backed anabelae type; evidently the San Pedro Martir mountain breeders drop down the west slope for the winter. Coming back across the mesa, I encountered a small company of Black-tailed Gnatcatchers, taking one, probably a new race; notes different from those of P. californica -- like local Vigors Wren calls or Spotted Towhee's -- chi-chi-chi, nasal, but not the kittenish whine of californica. Also met with several Bell Sparrows, and several companies of Intermediate Sparrows. A 10-year old girl, Ada Meling, catches lizards for me. The following she got by turning over boards and stones around the ranch early in the forenoon while the lizards are yet numb from the cold (there was frost this morning here). 6527 Eumeces (under board) 6528 Cnemidophorus 6529 - 6535, 7 specimens of Sceloporus.

The barometer tonight (7 p.m.) reads 27.15 in.; it is warm and the sky is partly overcast, cirrous.

Hunted for two hours this morning, 7:30-9:30, down along hillsides below the ranch and then into the willows. The feature of the day was the taking of a pair of Hutton's Vireo, in willows. I found them when scrutinizing a peripatetic band of Bush-tits for possible camp followers. The two were closely attentive to one another, keeping within a maximum distance of 8 feet of one another. They were absolutely quiet and might easily have been passed up for Kinglets.

at 5:30 (broad daylight) I went up on the hills. Heard a Bell Sparrow give its melodious tinkle; and at least 3 Calif. Thrashers were singing in abbreviated style. At daybreak I heard, in addition to the cries of Killdeer, the “scaipe” of a Wilson Snipe. Tonight at dusk I heard a Screech Owl in the willow-bottom, and heard a Poor-will in the ranch yard.

Oct 19 Put out 22 rat and mouse traps last night on a gently rising open hillside west of the ranch where I had seen dipodomys workings. Took 4 Dipodomys and 2 Periomyscus maniculatus; the latter ((male sign) and (female sign) with 4 embryos) and one of the former ((male sign)), discarded.

6556 Gerrhonotus Total length, 370 mm.

This forenoon, 7:30 to 12:00, I went horseback 3 miles west of the ranch, up onto the mesa and on to the live-oak ravine where the “arrastre” is.

There was a little seepage there, and some rainwater in granite bowls in the stream-course. Large numbers of Valley Quail centered there. The following are the birds I saw, by individuals, from memory; but there were so few, I believe I am close & correct. Red-shafted Flicker (2); San Lucas Flycatcher (1, shot); Calif Jay (10±) Audubon Warbler (16±); Ruby-crown Kinglet (1); Spotted Towhee (5); Brown Towhee (4); Green-backed Goldfinch (1); Lawrence Goldfinch (1, seen and heard in flight overhead); Intermediate Sparrow (20±); Bell Sparrow (2); Calif. Thrashers (3); Shrike (one, very shy, seen and heard repeatedly, but refused to be stalked); Bewick Wren (3); Rock Wren (2); Valley Quail (40±). Horseback is a good way of taking a census, as it increases the range of vision, though chances of hearing high-pitched voices are less because of the squeakings of the saddle, rattle of the bit-chain, etc. I rather think that a foot in most productive, as a person can stop instantly, in perfect quiet, and listen and look; while the horse takes time to come to a standstill and even then fidgets. Of mammals, I saw one Jack Rabbit, and one Bush Rabbit, the latter, as usual in Adenostoma bush. Large bare areas in the mesa, adjacent to sage-bush and juniper, showed great amounts of Dipodomys sign — of the same sort as where I am trapping, near the ranch; this is of the heermanni or paramintinus kind and not of the agilis brand, it seems to me.

Early this morning I saw a Pigeon Hawk fly over the ranch. It was stockier that (sic) a Sparrow Hawk, somewhat broader wings, and decidedly darker in general color effect. Also I saw a Lewis Woodpecker fly from post to post along a pasture fence. Tonight I again heard a Poor-will and a Screech Owl. 6560 San Lucas Flycatcher (female sign) im. 10.8g. Shot in live oak 6561 Rock Wren (male sign) ad. 17.4g. Shot off of granite boulder. 6562 Spotted Towhee (male sign) ad. 38.6g. Shot from small oak. 6563 Calif. Jay (female sign) ad. 75.0g. Shot from small oak. Oct. 20 Besides the following 4 mammals saved, my 22 mouse and rat traps brot only a Peromyscus maniculatus, (male sign), discarded, under a sage-bush. 6564 Ammospermophilus (female sign) 91.5g. 223x69x38x4. In rat-trap on open hill-top. 6565 Dipodomys (male sign) 50.0g. 267x151x40x13. In rat-trap on open hill-top. 6566 Dipodomys (female sign) 51.2g. 273x161x41.5x11.5. In rat-trap on open hill-top. 6567 Dipodomys (male sign) 63.2. 286x171x40x12. In rat-trap on open hill-top. Before breakfast, 5:30-6:45, I went up the valley looking for rabbits; none seen. Saw, and downed, a Cooper Hawk, but failed to find it in the dense brush. Later, 8-12, Lamb and I went up on the mesa and across the anastre (?) ravine where the live oaks are to get jays - which we did. We only heard the Shrike, and barely glimpsed a Black-tailed Gnatcatcher. Other birds about as yesterday over the same route, save that I
