192 THE CONDOR VoL. X (?uerquedula cyan0ptera. Cinnamon Teal. Two pairs of these little ducks were to be found at the extreme west end of the lake during my entire stay. Neither nest was found, altho both were'certainly there. This is by far the high- est altitude at which I have noted these birds nesting; but both pairs were prob- ably strays from the Columbia River. Cypsel0ides niger. Black Swift. These swifts were very common at the west end of the lake, and might be seen in flocks of fifty or more at almost any time of day. As the mountains were approached they rapidly became rare, until at an altitude of a little over 2000 feet they were very seldom seen at all. No evidences of nesting sites were found, nor could I obtain any reliable reports that any had ever been found. Aer0nautes melan01eucus. White-throated Swift. Less common than the foregoing, but seen going into crevices near the east end of the lake in the in- accessible cliffs along the Columbia. One has no conception whatever of the rapidity of bird flight until he has seen one of these winged meteors travelling at full speed. Stellulacalli0pe. Calliope Hummingbird. Found at both ends of the lake, but near the west end in the vicinity of 1500 feet altitude these birds were extremely numerous. I found great difficulty in locating the nests, only one set of two fresh eggs being found. This was taken on June 12, my attention being attracted to it by the savage attack of the female upon a passing Western Robin. l?lucifraga c01umbiana. Clarke Crow. These most interesting birds were rather plentiful near the west end of the lake, where they seemed to prefer an altitude of. a little over 1500 feet. Here on June 13 I located the only nest of the trip, which was disclosed to me by the parent birds carrying food to the young. It was about 150 feet up in a large bull pine, near the top where some disease of the foliage had caused an almost solid cluster four feet in diameter. As regards visiting the nest the old birds were extremely shy, never going to it if they knew I was in the vicinity. This was apparently not at all to the liking of the young ones, whose continuous cries of chart could be plainly heard from the ground. They sounded very much like half-grown crows. My presence did not seem to cause the adults any personal alarm whatever, and I spent considerable time watching them at only a few yards distance. They seemed to find an equal abundance of food in the trees and on the ground, bat I was surprised to find them such expert and assiduous fly- catchers. Large beetles and a dull-colored miller were very abundant, and these the nutcrackers caught in mid-air with a speed and accuracy that was remarkable in such heavily built birds. It is probable that the above mentioned nesting record is most unusual, both as to date and altitude, for doubtless .they usually nest much earlier in the season and higher up in the mountains. Hesperiph0na vespertina montana. Western Evening Grosbeak. While not precisely common, these handsome birds were to be seen every day in the vicinity of 2000 feet altitude. No nests were found, nor did the birds show any indica- tions of nesting. Spizella s0cialis ariz0me. Western Chipping Sparrow. This extremely com- mon little bird deserves mention for the almost unlimited latitude of its distribu- tion. It is to be found literally everywhere, rearing its young in the sun-baked sage bushes, the cool orchard trees of some irrigated garden, and again is found equally numerous on the fir-clad slopes of the mountains. Many a disappoint- ment has met me at the end of a hard climb, only to find a sparrow's nest where I had hoped for some rare warbler. And this in the wildest mountains where the presence of a socialis seemed quite beyond belief.
