July, 1916 ON BICYCLE AND AFOOT IN THE SANTA CATALINA MTS. 159 were to reach the summit that day and the trail was a long, hard one. We then went down to the Zone-tail's nest, which Howard elirobed. The female left the nest as he ascended, and alighted on a nearby hillside where she kept up an intermittent screaming, ably seconded by her mate who had come at the first alarm. The nest was seventy-eight feet from the ground, was composed of sticks with a few green leaves for lining, and contained two incubated eggs. This Was a strictly characteristic nest. We hurried on after Chrisman, and spent several toilsome hours climbing the trail. At one point it was so steep that he had to go up ahead with a rope and steady the horses to keep them from falling over backward as they elirobed. After passing this place we were soon at the edge of the pines. Painted Redstarts greeted us, but were net yet nesting though it was late for them. This was due no doubt to the dry season, for they usually begin nest- ing in April. Some Long-crested Jays, Western Flycatchers, and several other' common species were met with. In a small weed growing on a perpendicular wall of rock we found a nest of Broad-billed Hummingbird (Cynanthus latir- ostris) with two dried-up eggs. This was the only nest of this species found on the trip. As we got up among the pine trees the needles made wallring very diffi- cult. They covered the trail with a coating as slippery as ice. On one zigzag portion three white-tailed deer jumped up, and, with amazing ease, tore away across the mountain side and out of sight. A little later a series of excited yelps attracted our attention, and four more deer went by, with the little yellow camp dog following. About four o'clock we topped the ridge and were rejoiced to hear that "Bear .Wallow cabin" was a scant mile farther up. A beautiful pine and fir forest covered the whole mountain top with giant trunks, many of which were over four feet in diameter and a hundred feet tall. As we passed Bear Wallow spring a flock of about thirty Western Evening Grosbeaks flew up from their evening drink and scattered among the nearby trees. A hundred yards farther and we were at the cabin. The guide had already arrived and the horses were grazing nearby, hobbled and belled. A fire was soon going, and while supper was cooking we prepared the bunks. A goodly supply of blankets was already in the cabin, and we were glad to have the extra number as the air was very cold at this altitude of over 8000 feet. We were up at daylight the next morning and out among the trees by sunrise. The Western Evening Grosbeaks were again at the spring when ] went for a pail of water. A thin film of ice was on the shallow pool Ruby- crowned Kinglets and Audubon Hermit Thrushes were singing in several directions. Starting out after breakfast, we soon had our attention arrested by a pair of Evening Grosbeaks fighting some Long-crested Jays. We located and collected their nest as I have recorded in a former article (see CONDOR Xll, 19?0, p. 60). Several completed nests of Audubon Hermit Thrush (Hylocichla guttata auduboni) were found, some a few feet from the ground in small fir trees, and one in a hollow of a rotten pine stump. None of them held eggs, and all were deserted subsequently as Howard discovered on returning early in June. Chest- nut-backed Bluebirds and Arizona Juneos were fairly common, as were the Pigmy Nuthatches, of which we found several nests with young. Our greatest surprise was a family of Clarke Nutcrackers (Nucifraga columbiana), two mature birds and three fully fledged young almost as large as their parents. The young birds
