July, 1916 ON BICYCLE AND AFOOT IN THE SANTA CATALINA MTS.

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 climbed. 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 
climbed. After passing this a place we were soon at the edge of the pines. 
Painted Redstarts greeted us, but were not 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 ( Gynanthus 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 walking 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 w r ere 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 I 
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 xii, 
1910, 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 J uncos 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
