 180 THE CONDOR Vol. XVIII up, held two fresh eggs. I succeeded in getting a photo of this nest (see fig. 47). Both nests were found by watching the birds. Both were small and rather poorly made, of weed fibres. This hummingbird was quite common, but further search for nests was unsuccessful as usually the birds would dart off into the top of the high pines and firs anywhere from seventy-five to over a hundred feet up, at which distances one could not follow them. $ayornis nigricans. Black Phoebe. Seen several times on June 23 in a little can- yon near Pine Knot Lodge, and again on the same date near the dam. rnpidonax wrighti. Wright Flycatcher. Wright Flycatchers were very common all through the western end of the valley, frequenting the buckthorn from the lake shore up into the little canyons and even up to the higher idges. I failed to find any of these birds about the east end of Bear Lake or about Baldwin Lake. Many nests Fig. 47. NEST OF CALLIOPE I-UiflfINGBIRD, THIRTY FEET ABOVE THE GROUND; NEAR BEAR LAKE, SAN BERNARDINO MOUNTAINS, JUNE 24, 1916 were located, nearly always in buckthorn from 2 to 3 feet up (see fig. 48). Two nests were found in manzanita and three in oak bushes. The sets were uniformly of four eggs. On June 22 nests with large young were found, and others with fresh eggs on the same date. Two nests just being built were discovered on June 29. Probably the later sets were caused by the first nests being destroyed. This seems to happen often, as several nests under observation were undoubtedly robbed by the chipmunks which infest all the brush in great numbers in this region. Passerella Iliaca stephensl. Stephens Fox Sparrow. Considerable time was spent in trying to locate a nest of this species, but without results except that I am almost certain it nests either on the ground or very low down under the thick brush.
