Sept., 1916 MORE BIRD NOTES FROM BIG BEAR VALLEY 179 Oreortyx picta piurnifera. Plumed Partridge. Abundant near Baldwin Lake, June 19; several flocks of young of various sizes seen, from small birds to some nearly half- grown. I saw a flock of very small young, eight or ten of them, at Bluff Lake on June 20, and on Jnne 29, two broods of small young in the same locality. In an open field near the I. S. Ranch store I saw an old bird on June 24, with three small young not over a day old. Sphyrapicus varius daggetti. Sierra Sapsucker. I located a nest by watching the bird on June 26. The cavity was in the dead top of a large live silver fir about forty- fiye feet up. The cavity had a small opening and was only 5 or 6 inches deep; diame- tel inside, 1? or 2 inches. The nest held two large young and one smaller dead one. It was hard to see how more than one bird could survive in such a small space, so it was not surprising that the probably weaker bird had apparently been suffocated. Chordeiies virginianus hesperis. Pacific Nighthawk. Pacific Nighthawks were quite common flying over the east end of Bear Lake as we entered the valley on June Fig. 46. EGGS OF PACIFIC NIGHTHAWK, IN PLACE; NEAR BEAR LAKE, SAN BERNARDINO MOUN- TAINS, JUNE 22, 1916 19. Three sets of eggs were found on the little ridges about one-half mile back from the lake shore and not far distant from Pine Knot Lodge. In the first instance, June 22, the eggs were laid on the bare earth in a cavity scratched out by the bird (see fig. 46). The second set, found June 24, was laid on the leaves and pine needles under an oak tree; and the last set on a little patch of bare earth 'from which the leaves had apparently been scratched away, also under an oak bush. Incubation was well started in each set. In each instance the eggs were found by flushing the bird, but even then they were rather difficult to locate. Late in the morning on June 30, there were at least a hundred of these birds feeding over the east end of Bear Lake. Several were taken and all were adult breeding males. Steiiuia calliope. Calliope Hummingbird. Two nests of this hummingbird were located on June 24 in a little canyon near the lake shore. One on a small branch about 45 feet up and almost inaccessible, but which I finally obtained, contained two heavily incubated eggs. The other nearer the trunk of a large pine and about 30 feet
