Hummingbird's nest was found July 2 (p. 2513). With glasses saw the bird siting; then I climbed. Set 1/2 and nest taken. Female shot after I came down, as she buzzed about the vacant site. She had left the nest, when I had gotten within 4 feet below her.

Sierra Junco's nest with five eggs taken: ^^{[incubation advanced]} completely sheltered from above under awning found by broken-off end of 8 inch log overgrown by tall grass and herbage. Nest, taken, well above ^^{(45 mm. to rim)} level of surrounding sod; in fact, nothing on ground, not in hollow, as is often the case: [illustration of nest and log] Grass grows up all about it: [illustration of nest and log continued]. Bird flushed only when I happened to put my foot down scarcely ten inches from her. In meadow, in partial shadow of numbers of smallish lodgepole pines in a tract.

Mountain Chickadee's nest with 5 half-grown young; in ^^small burnt stub standing in edge of meadow; cavity apparently natural, rotted out, inside a vertical split, 25 mm., at widest; lower edge at bottom of split, 1580 mm. (only) above ground; nest-cavity inside about 175 mm. lower. Looking down in through the entrance crevice, one could see in the darkness only the five yellow bill-edges (corners of the mouth chiefly), shining forth.

Wood Pewee's nest, saddled in forking of live lodgepole pine limb about 30 feet above the ground; limb extending south, out over meadow. Adults seen

Last spec. no. 6292

Stu and I in the machine left Berkeley at 4 yesterday afternoon, slept on the "badlands" midnight to 4:45 a.m., left Red Bluff at 6:15 a.m. and reached the family camp above Mineral at 9:45 a.m. Notable along the highway within 12 miles below Red Bluff were the Yellow-billed Magpies, 2 to 6 or 8 in sight at once and very tame, on the ground or roadside fences with autos passing close by. At Dale's on Paine Creek, although 7:30 a.m., hardly any birds now singing; a Wood Pewee was drawling, and a Chat singing fitfully, more so than normally. Within a mile above Dale's, a Roadrunner sped ahead of us a little ways, then made off among the boulders. From Dale's clean up to the first yellow pines (at 3200 about) I was impressed by the numbers of Douglas Ground Squirrels and Jack Rabbits; numbers of partly grown young of each species were seen. Below (west of) Battle Creek Meadows along the highway up the north wall of the canyon about the bridge, I saw at least 8 Callospermophilus, one of them not over 1/3 grown. An adult was seen at the roadside close to the north side of the Meadows. This species seems to come down with the fir belt from the high mountain immediately to the north. Here at camp I am impressed by the quietness of the birdlife. Once in a while there is the broken song of a Fox Sparrow; and the Chickadee's "tee-tee, too, too" is heard; but

foliage which the breeze kept in disconcerting agitation); Cassin Purple Finch (2 or more, distantly heard and seen in tops of hemlocks); Sierra Grouse (2, as above); Hammond Flycatcher (2 immatures, separately, seen closely in hemlocks at 8000 to 9000 ft.); Junco (2, in hemlocks).*

In the red-fir belt (Canadian), 8000 ft., about, down to 7000 ft., where we left the machine, noted: Deer (doe and fawn at edge of alder thicket); Callospermophilus (2 or more); Thomomys monticola (sign common); Fox Sparrow (one immature near patch of heather along little stream at 8000 ft., and others heard in alder patches); Juncos (commonest bird, one [male symbol] singing at tip of lofty red fir - many full-grown young in scattering troupes); Evening Grosbeak (one family of 5 or so alighted on dead lower branches of a fir and notes of others were heard now and then); Solitaire (one flushed from ground); Siskin (notes of 2 or 3 heard overhead); Blue-fronted Jay (heard several times); Cassin Vireo (2 immatures closely seen in a jungle of white alders); Hammond Flycatcher (weak call notes heard often, and one bird seen, 30 feet or so up in densely shaded branchwork of fir); Wood Pewee (pair at 7000 ft.); Pileated Warbler (song of one heard from alders); Robin (a pair at a little ^^moraine lake in the fir woods was noisily concerned at our presence); Audubon Warbler (a family, male singing, in trees at this same lake); Canada Nuthatch (notes heard in the distance).
