 164 THE CONDOR Vol. XVII this sabling the birds would alight, usually about three feet from the base, "hitch" quickly backwards down the trunk to the water, and, leaning sharply to one side, drink by quick, nervous dips. One was seen actually on the sand, evidently preparatory to drinking or bathing, but was frightened away by our approach. $phyrapcus rube dag.gettl. Sierra Sapsucker. Not uncommon about Bluff Lake. Noticeably fewer in numbers at Bear Lake. All those taken were juvenals in nearly complete fall plumage, though all retained a belt of old feathers across the upper breast. In common with the Williamson Sapsuckers they were most often seen near the head- waters of the numerous little canyons running into the two lakes. There they were often gathered in threes or fours, flycatching after the manner of the California Wood- pecker. On several occasions a Williamson was noted with these groups. $phyrapicus thyroldeus. Williamson Sapsucker. Noted over the same range and in about the same numbers as the last species. Adults and young alike had entirely com- pleted the fall molt. Chordeiles virginianus hesperis. Pacific Nighthawk. One flew over camp at Bear Lake at sunset on the 18th of September. A long wait by th lake shore at dusk re- sulted in the sight of one (perhaps the same bird) flying over the lake. Chaetura vauxi. Vaux Swift. A group of three seen flying west along the shore of Bear Lake, September 18. Caiypte anna. Anna Hummingbird. Female taken at Bear Lake, September 22. $tellula calliope. Calliope Hummingbird. Apparently rather common near the sum- mit above Clark's Ranch, where several females cr young were feeding from a patch of flowers on September 16. Nuttallornis bcrealis. Olive-sided Flycatcher. Still present in considerable numbers. Noted over the entire region covered. Myiochanes richardsoni. Western Wood l'ewee. A pair was usually in evidence about camp at Bear Lake. Last noted cn September 20, when a young bird was taken at a water hole about half way between Bear and Baldwin lakes. This bird was in juve- nal plumage and was accompanied by two adults. Empidonax wrighti? Wright Flycatcher. One was seen at very close range in a willow clump near Bear Lake on September 22. Flycatchers were seen on one or two other occasions previous to this, but none was taken. Otocoris aipestris actla. California Horned Lark. Rather uncommon in the dry pastures near Bear Lake. Cyanocitta stelleri frontalis. Blue-fronted Jay. Though most of the year's young, and all the adults, apparently had completed the fall molt, one juvenal taken Septem* bet 18 was still in ragged plumage. The old feathers still predominated on the upper parts, head and neck, and on the central underparts. Apheiocoma californica. California Jay. Though common on the lower, chaparral* covered slopes, this species was noted but once in the higher mountains, where a bird was seen near the divide between Bear and Baldwin lakes, at 7000 feet. Cyanocephaius cyanocephalus. Pinyon Jay. Common in good sized, straggling flocks, about the east end of Bear Lake, and in smaller numbers about Bluff Lake. In the series taken the adults average lighter in color, and the feathers already show signs of wear, while the birds of the year are in more recently acquired, and consequently brighter, plumage. Pooecetes gramineus confinis. Western Vesper Sparrow. Apparently not uncommon on the dry brushy flats near the Bast end of Eear Lake. First noted September 17. Zonotrichia leucophrys gambeil. Gambel Sparrow. First noted September 18, when one was taken at Bear Lake. Seen thereafter in small numbers. Passereiia iliaca schistacea. Slate-colored Sparrow. Two' taken September 23, one on the summit between Bluff Lake and the Santa Ana Canyon, and another in the dense manzanita brush above Clark's Ranch in the same canyon. Five or six were noted scattered between these two points. Passereiia iilaca stephensi. Stephens Fox Sparrow. Still present in the mountains, though not in anything like the numbers in which it is found during the summer months. Apparently absent altogether from the immediate vicinity of Bluff Lake, where during the breeding season it is abundant. Eight specimens were taken, one on the summit between Bluff Lake and the Santa Ana Canyon (September 16), and seven in a small canyon near the east end of Bear Lake (September 22). All were seemingly adults and
