Several times down Truckee Canyon I have seen wild canaries. They are rather rare, as are also the Louisiana tanager, most gorgeous of all the Tahoe birds, and the black-headed grosbeak.
Of the wrens, both the rock wren and the canyon wren are occasionally seen, the peculiar song of the latter bringing a thrill of cheer to those who are familiar with its falling chromatic scale.
Then there is the merry chick-a-dee-dee, the busy creepers, and the nut-hatches hunting for insects on the tree trunks.
The harsh note of the blue jay is heard from Tahoe Tavern, all around the Lake and in almost every wooded slope in the Sierras. He is a noisy, generally unlovable creature, and the terror of the small birds in the nesting season, because of his well-known habit of stealing eggs and young. At Tahoe Tavern, however, I found several of them that were shamed into friendliness of behavior, and astonishing tameness, by the chipmunks. They would come and eat nuts from my fingers, and one of them several times came and perched upon my shoulder. There is also the grayish solitaire which looks very much like the mockingbird of less variable climes.
The foregoing account of the birds, which I submitted for revision to Professor Peter Frandsen, of the University of Nevada, called forth from him the following:
I have very little to add to this admirable bird account. Besides the gulls, their black relatives, the swallow-like terns, are occasionally seen. The black-crowned night-heron is less common than the great blue heron. Clarke's crow is more properly called Clarke's nutcracker—a different genus. The road robin or chewink is fairly common in the thickets above the Lake. Nuttal's poor will, with its call of two syllables, is not infrequently heard at night. The silent mountain blue-bird, sialia arctica, is sometimes seen. So is the western warbling vireo. The solitary white-rumped shrike is occasionally met with in late summer. Owls are common but what species other than the western horned owl I do not know. Other rather rare birds are the beautiful lazuli bunting and the western warbling vireo. Among the wood-peckers I have also noted the bristle-bellied wood-pecker, or Lewis's wood-pecker, Harris's wood-pecker, and the downy wood-pecker.
ANIMALS. These are even more numerous than the birds, though except to the experienced observer many of them are seldom noticed.
While raccoons are not found on the eastern slopes of the High Sierras, or in the near neighborhood of the Lake, they are not uncommon on the western slopes, near the Rubicon and the headwaters of the various forks of the American and other near-by rivers.
Watson assured me that every fall he sees tracks on the Rubicon and in the Hell Hole region of very large mountain lions. They hide, among other places, under and on the limbs of the wild grapevines, which here grow to unusual size. In the fall of 1912 he saw some strange markings, and following them was led to a cluster of wild raspberry vines, among which was a dead deer covered over with fir boughs. In telling me the story he said:
I can generally read most of the things I see in the woods, but this completely puzzled me. I determined to find out all there was to be found. Close by I discovered the fir from which the boughs had been stripped. It was as if some one of giant strength had reached up to a height of seven or eight feet and completely stripped the tree of all its lower limbs. Then I asked myself the question: "Who's camping here?" I thought he had used these limbs to make a bed of. But there was no water nearby, and no signs of camping, so I saw that was a wrong lead. Then I noticed that the limbs were too big to be torn off by a man's hands, and there were blood stains all about. Then I found the fragments of a deer. "Now," I said to myself, "I've got it. A bear has killed this deer and has eaten part of it and will come back for the rest." You know a bear does this sometimes. But when I hunted for bear tracks there wasn't a sign of a bear. Then I assumed that some hunter had been along, killed a doe (contrary to law), had eaten what he could and hidden the rest, covering the hide with leaves and these branches. But then I knew a hunter would cut off those branches with a knife, and these were torn off. The blood spattered about, the torn-off boughs and the fact that there were no tracks puzzled me, and I felt there was a mystery and, probably, a tragedy.
But a day or two later I met a woodsman friend of mine, and I took him to the spot. He explained the whole thing clearly. As soon as he saw it he said, "That's a mountain-lion." "But," said I, "Where's his tracks?" "He didn't make any," he replied, "he surprised the doe by crawling along the vines. I've found calves and deer hidden like this before, and I've seen clear traces of the panthers, and once I watched one as he killed, ate and then hid his prey. But as you know he won't touch it after it begins to decompose, but a bear will. And that's the reason we generally think it is a bear that does the killing, when in reality it is a mountain lion who has had his fill and left the remains for other predatory animals, while he has gone off to hunt for a fresh kill."
