Today, 7:20 to 12:20, I took a strenuous walk about 5 miles due east to the jumping-off place, in other words to the eastern rim of the San Pedro Martir plateau. I went up the Arroya La Encantada to the big main "meadow" (now just weeds -- the tall slender composite with inconspicuous flowers, sample saved from near camp); then off along the eastern arm of this flat and up a draw over a divide at, I think, about 8000 feet, and down into the head of El Cajon Canyon which makes down precipitously onto the San Felipe Desert. I climbed a hill and got a fine view east, across the San Felipe desert, then the San Felipe range of desert mountains, then a further strip of desert, and then the gulf, beyond which I could

see in very faint outline the mountains of Sonora. The panorama reminded me strongly of that seen from the Santa Rosa or San Jacinto mountains of southern California eastward. Toward the top of the divide the prevailing Jeffrey pines were mixed with some white fir, incense cedar and sugar pine; and in the rough hills adjoining the pass were numerous scrubby oaks, and rather dense chaparral of manzanita, buckthorn, and cascara. It was here, on the dessert slope of the divide, that I encountered the three Calif. Jays. The following census was pencil checked on card-board on the way out, from camp to my farthest point over the divide, 7:20 to 10:00. Pigmy Nuthatch 68; Audubon Warbler 5 (only along the stream); Bluebird 10; Cabanis Woodpecker 6; Townsend Junco 13; Chickadee 10; Raven 5; Red-tailed Hawk 2; Pinyon Jay 1 (heard); Olive-backed Thrush (1, in cascara bush); Canyon Wren 2; Williamson Sapsucker 1; Slender-billed Nuthatch 4; Red-shafted Flicker 1; Spurred Towhee 1; Siskin 5; Calif. Jay 3. Total, 17 species, 138 individuals, in 2 2/3 hours. Note that just about half of all the birds noted were Pigmy Nuthatches! Of mammals I checked in the same period; Chipmunk 28;Scirus 2 (in pine near divide); Wildcat (one out in open meadow in bight sunshine; bounded up a draw; may have been laying for birds coming to drink at the seepage near where he was); on the way down
