Birds of the Rockies Part 11

The old birds of both s.e.xes circled overhead, called and pleaded and scolded, and sometimes swooped down quite close to my scalp, always veering off in time to avoid actual collision. A pair of them held choice morsels--choice for Brewer's blackbirds--in their bills, and I sat down on a tuft of sod and watched them for a couple of hours, hoping they would feed their young in plain sight and divulge their secret to me; but the sable strategists flitted here and there, hovered in the air, dropped to the ground, visiting every bush and gra.s.s-tuft but the right one, and finally the worms held in their bills disappeared, whether into their own gullets or those of their fledgelings, I could not tell. If the latter, the rascals were unconscionably wary, for my eyes were bent on them every moment--at least, I thought so. Again and again they flew off some distance, never more than a stone's throw, strutted about for a few minutes among the tufts of gra.s.s and sod, then came back with loud objurgations to the place where I sat. They seemed to be aware of my inspection the moment my field-gla.s.s was turned upon them, for they would at once cease their pretended search for insects in the gra.s.s and fly toward me with a clamorous berating giving me a big piece of their mind. At length my patience was worn out; I began to hunt for nests, and found the three empty abodes to which allusion has been made.

For the most part the female cried, "Chack! chack!" but occasionally she tried to screech like her ebon consort, her voice breaking ludicrously in the unfeminine effort. The evening before, I had flushed a youngster about which a great hubbub was being made, but on the day of my long vigil in the meadow, I could not, by the most careful search, find a single bantling, either in or out of a nest. It is odd how effectually the young are able to conceal themselves in the short gra.s.s and straggling bushes.

Not a little attention was given to the western savanna sparrows, whose songs have already been described. Abundant proof was furnished that the breeding season for these little birds was at its height, and I determined to find a nest, if within the range of possibility. An entire forenoon was spent in discovering three nests. As you approach their domiciles, the c.o.c.ks, which are always on the alert, evidently give the alarm to their sitting mates, which thereupon slip surrept.i.tiously from the nest; and in that case how are you going to ferret out their domestic secrets?

A female--I could distinguish her from her consort by her conduct--was sitting on the post of a wire fence, preening her feathers, which was sufficient evidence that she had just come from brooding her eggs. To watch her until she went back to her nest, then make a bee-line for it--that was the plan I resolved to pursue. It is an expedient that succeeds with many birds, if the observer is very quiet and tactful. For a long time I stood in the blazing sun with my eyes bent on the little impostor. Back and forth, hither and yon, she flew, now descending to the ground and creeping slyly about in the gra.s.s, manifestly to induce me to examine the spot; then back to the fence again, chirping excitedly; then down at another place, employing every artifice to make me think the nest was where it was not; but I steadfastly refused to budge from my tracks as long as she came up in a few moments after descending, for in that case I knew that she was simply resorting to a ruse to lead me astray. Finally she went down at a point which she had previously avoided, and, as it was evident she was becoming exceedingly anxious to go back upon her eggs, I watched her like a tiger intent on his prey. Slyly she crept about in the gra.s.s, presently her chirping ceased, and she disappeared.

Several minutes pa.s.sed, and she did not come up, so I felt sure she had gone down for good this time, and was sitting on her nest. Her husband exerted himself to his utmost to beguile my attention with his choicest arias, but no amount of finesse would now turn me from my purpose. I made a bee-line for the spot where I had last seen the madame, stopping not, nor veering aside for water, mud, bushes, or any other obstacle. A search of a couple of minutes brought no find, for she had employed all the strategy of which she was mistress in going to the nest, having moused along in the gra.s.s for some distance after I had last seen her. I made my search in an ever-widening circle, and at length espied some dry gra.s.s spears in a tuft right at my feet; then the little prospective mother flitted from her nest and went trailing on the ground, feigning to be fatally wounded.

Acquainted with such tactics, I did not follow her, not even with my eye, but looked down at my feet. Ah! the water sprites had been kind, for there was the dainty crib, set on a high tuft of sod raised by the winter's frosts, a little island castle in the wet marsh, cosey and dry.

It was my first savanna sparrow's nest, whether eastern or western. The miniature cottage was placed under a fragment of dried cattle excrement, which made a slant roof over it, protecting it from the hot rays of the sun. Sunken slightly into the ground, the nest's rim was flush with the short gra.s.s, while the longer stems rose about it in a green, filmy wall or stockade. The holdings of the pretty cup were four pearls of eggs, the ground color white, the smaller end and middle peppered finely with brown, the larger almost solidly washed with pigment of the same tint.

Two more savannas' nests were found not long afterwards, one of them by watching the female until she settled, the other by accidentally flus.h.i.+ng her as I walked across the marshy pasture; but neither of them was placed under a roof as the first one had been, the blue dome being their only shelter. These birdlets seem to be especially fond of soggy places in pastures, setting their nests on the little sod towers that rise above the surrounding water.

All the birds seen in the park have now been mentioned. It was an idyllic spot, and I have often regretted that I did not spend a week in rambling over it and making excursions to the engirdling ridges and peaks. A few suggestive questions arise relative to the migratory habits of the feathered tenants of a mountain park like this, for most of those that have been named are only summer residents. How do they reach this immured Eden at the time of the spring migration? One may conjecture and speculate, but one cannot be absolutely sure of the precise course of their annual pilgrimage to their summer Mecca. Of course, they come up from the plains, where the spring arrives much earlier than it does in the higher alt.i.tudes. Our nomads may ascend by easy stages along the few canons and valleys leading up from the plains to this mountain-girt plateau; or else, rising high in air at eventide--for most birds perform their migrations at night--they may fly over the pa.s.ses and mountain tops, and at dawn descend to the park.

Neither of these hypotheses is free from objection, for, on the one hand, it is not likely that birds, which cannot see in the dark, would take the risk of das.h.i.+ng their brains out against the cliffs and crags of the canons by following them at night; yet they may depart from their usual habit of nocturnal migration, and make the journey up the gorges and vales by day. On the other hand, the nights are so cold in the elevated regions that the little travellers' lives might be jeopardized by nocturnal flight over the pa.s.ses and peaks. There is one thing certain about the whole question, perplexing as it may be--the feathered pilgrims reach their summer quarters in some way, and seem to be very happy while they remain.

We stopped at a number of places in our run down South Platte Canon, adding no new birds to our list, but making some interesting observations. At Ca.s.sel's a house-wren had built a nest on the veranda of the hotel where people were sitting or pa.s.sing most of the time, and was feeding her tiny brood. In the copse of the hollow below the resort, the mountain song-sparrows were trilling sweetly--the only ones we had encountered in our wanderings since leaving Arvada on the plains. These musicians seem to be rather finical in their choice of summer resorts.

Chaseville is about a mile below Ca.s.sel's, and was made memorable to us by the discovery of our second green-tailed towhee's nest, a description of which I have decided to reserve for the last chapter of this volume.

Lincoln's sparrows descanted in rich tones at various places in the bushy vales, but were always as wild as deer, scuttling into the thickets before a fair view of them could be obtained.

The veranda of a boarding-house at Shawnee was the site of another house-wren's nest. While I stood quite close watching the little mother, she fed her bantlings twice without a quaver of fear, the youngsters chirping loudly for more of "that good dinner." At this place barn swallows were describing graceful circles and loops in the air, and a sheeny violet-green swallow squatted on the dusty road and took a sun-bath, which she did by fluffing up all her plumes and spreading out her wings and tail, so that the rays could reach every feather with their grateful warmth and light. It was a pretty performance.

"_Squatted on the dusty road and took a sun-bath_"]

A stop-over at Bailey's proved satisfactory for several reasons, among which was the finding of the Louisiana tanagers, which were the first we had seen on this trip, although many of them had been observed in the lat.i.tude of Colorado Springs. Afterwards we found them abundant in the neighborhood of Boulder. The only pigmy nuthatches of this visit were seen in a ravine above Bailey's. In the same wooded hollow I took occasion to make some special notes on the quaint calls of the long-crested jays, a task that I had thus far deferred from time to time. There was an entire family of jays in the ravine, the elders feeding their strapping youngsters in the customary manner. These birds frequently give voice to a strident call that is hard to distinguish from the cries of their kinsmen, the mountain jays. When I pursued the couple that were attending to the gastronomical wants of their children, one of the adults played a yodel on his trombone sounding like this: "Ka-ka-ka, k-wilt, k-wilt, k-wilt", the first three short syllables enunciated rapidly, and the "k-wilts" in a more measured way, with a peculiar guttural intonation, giving the full sound to the _k_ and _w_.

The birds became very shy when they thought themselves shadowed, not understanding what my pursuit might imply, and they gave utterance to harsh cries of warning that were different from any that had preceded.

It was presently followed by a soft and friendly chatter, as if the birds were having an interview that was exclusively _inter se_. Then one of them startled me by breaking out in a loud, high key, crying, "Quick!

quick! quick!" as fast as he could fling the syllables from his tongue.

This, being translated into our human vernacular, obviously meant, "Hurry off! danger! danger!" A few minutes of silence followed the outburst, while the birds ambled farther away, and then the echoes were roused by a most raucous call, "Go-ware! go-ware! go-ware!" in a voice that would have been enough to strike terror to the heart of one who was not used to uncanny sounds in solitary places. After that outburst the family flew off, and I could hear them talking the matter over among themselves far up the mountain side, no doubt congratulating one another on their hair-breadth escape. The youngsters looked quite stylish with their quaint little blue caps and neatly fitting knickerbockers.

At Bailey's I found my first and only white-crowned sparrow's nest for this trip, although two years before I was fortunate enough to discover several nests in the valleys creeping from the foot of Pike's Peak. At dusk one evening I was walking along the railway below the village, listening to the sweetly pensive trills of the white-crowns in the bushes bordering the creek, when there was a sharp chirp in the willows, and a female white-crown darted over to my side of the stream and slipped quietly into a thick bush on the bank. I stepped down to the spot, and the pretty madame leaped away, uncovering a well-woven nest containing four white eggs speckled with dark brown. All the while her spouse was trilling with might and main on the other side of the creek, to make believe that there was nothing serious happening, no nest that any one cared anything about. His mate could not disguise her agitation by a.s.suming nonchalance, but flitted about in the willows and chirped pitifully. I hurried away to relieve her distress. The cottages on the slopes were gay with tourists enjoying their summer outing, and beautiful Kiowa Lodge, perched on a shoulder of the mountain among embowering pines, glowed with incandescent lights, while its blithe-hearted guests pursued their chosen kinds of pastime; but none of them, I venture to a.s.sert, were happier than the little white-crown in her gra.s.sy lodge on the bank of the murmuring stream.

On the way down the canon, as we were going to Denver, I was able to add three belted kingfishers to my bird-roll of Colorado species, the only ones I saw in the Rockies.

Our jaunt of 1901 included a trip to Boulder and a thrilling swing around the far-famed "Switzerland Trail" to Ward, perched on the mountain sides among the clouds hard by the timber-line. Almost everywhere we met with feathered comrades; in some places, especially about Boulder, many of them; but no new species were seen, and no habits observed that have not been sufficiently delineated in other parts of this book. If one could only observe all the birds all the time in all places, what a happy life the bird-lover would live! It is with feelings of mingled joy and sadness that one cons Longfellow's melodious lines:--

"Think every morning when the sun peeps through The dim, leaf-latticed windows of the grove, How jubilant the happy birds renew Their old, melodious madrigals of love!

And when you think of this, remember too 'Tis always morning somewhere, and above The awakened continents, from sh.o.r.e to sh.o.r.e, Somewhere the birds are singing evermore."

A NOTABLE QUARTETTE[12]

On the plains of Colorado there dwells a feathered choralist that deserves a place in American bird literature, and the day will perhaps come when his merits will have due recognition, and then he shall have not only a monograph, but also an ode all to himself.

[12] The author is under special obligation to Mr. John P. Haines, editor of "Our Animal Friends," and president of the American Society for the Prevention of Cruelty to Animals, for publis.h.i.+ng the contents of this chapter in his magazine in time to be included in this volume. Also for copyright privileges in connection with this and other chapters.

The bird to which I refer is called the lark bunting in plain English, or, in scientific terms, _Calamospiza melanocorys_. The male is a trig and handsome fellow, giving you the impression of a well-dressed gentleman in his Sunday suit of black, "with more or less of a slaty cast," as Ridgway puts it, the middle and greater wing-coverts bearing a conspicuous white patch which is both a diagnostic marking and a real ornament. In flight this patch imparts to the wing a filmy, almost semi-transparent, aspect. The bunting is about the size of the eastern bobolink, and bears some resemblance to that bird; but bobolink he is not, although sometimes mistaken for one, and even called by that name in Colorado. The fact is, those wise men, the systematists, have decided that the bobolink belongs to the family _Icteridae_, which includes, among others, the blackbirds and orioles, while the lark bunting occupies a genus all by himself in the family _Fringillidae_--that is, the family of finches, sparrows, grosbeaks, and towhees. Therefore, the two birds can scarcely be called second cousins. The bunting has no white or buff on his upper parts.

Sitting on a sunny slope one June evening, I surrendered myself to the spell of the bunting, and endeavored to make an a.n.a.lysis of his minstrelsy. First, it must be said that he is as fond as the bobolink of rehearsing his arias on the wing, and that is, perhaps, the chief reason for his having been mistaken for that bird by careless observers.

Probably the major part of his solos are recited in flight, although he can sit quietly on a weed-stalk or a fence-post and sing as sweetly, if not as ecstatically, as if he were curveting in the air. During this aerial performance he hovers gracefully, bending his wings downward, after the bobolink's manner, as if he were caressing the earth beneath him. However, a striking difference between his intermittent song-flights and those of the bobolink is to be noted. The latter usually rises in the air, soars around in a curve, and returns to the perch from which he started, or to one near by, describing something of an ellipse. The lark bunting generally rises obliquely to a certain point, then descends at about the same angle to another perch opposite the starting-point, describing what might be called the upper sides of an isosceles triangle, the base being a line near the ground, connecting the perch from which he rose and the one on which he alighted. I do not mean to say that our bunting never circles, but simply that such is not his ordinary habit, while sweeping in a circle or ellipse is the favorite pastime of the eastern bobolink. The ascent of neither bird is very high. They are far from deserving the name of skylarks.

We must give a detailed account of the bunting's song. Whatever others may think of him, I have come under the spell of his lyrical genius.

True, his voice has not the loud, metallic ring, nor his chanson the medley-like, happy-go-lucky execution, that marks the musical performances of the bobolink; but his song is more mellow, rhythmic, theme-like; for he has a distinct tune to sing, and sing it he will. In fine, his song is of a different order from that of the bobolink, and, therefore, the comparison need be carried no further.

As one of these minstrels sat on a flowering weed and gave himself up to a lyrical transport, I made careful notes, and now give the substance of my elaborate entries. The song, which is intermittent, opens with three prolonged notes running high in the scale, and is succeeded by a quaint, rattling trill of an indescribable character, not without musical effect, which is followed by three double-toned long notes quite different from the opening phrases; then the whole performance is closed by an exceedingly high and fine run like an insect's hum--so fine, indeed, that the auditor must be near at hand to notice it at all.

Sometimes the latter half of the score, including the second triad of long notes, is repeated before the soloist stops to take breath. It will be seen that the regular song consists of four distinct phrases, two triads and two trills. About one-third of the songs are opened in a little lower key than the rest, the remainder being correspondingly mellowed. The opening syllables, and, indeed, some other parts of the melody as well, are very like certain strains of the song-sparrow, both in execution and in quality of tone; and thus even the experienced ornithologist may sometimes be led astray. When the bunting sails into the air, he rehea.r.s.es the song just described, only he is very likely to prolong it by repeating the various parts, though I think he seldom, if ever, throws them together in a hodge-podge. He seems to follow a system in his recitals, varied as many of them are. As to his voice, it is of superb timbre.

Another characteristic noted was that the buntings do not throw back their heads while singing, after the manner of the sparrows, but stretch their necks forward, and at no time do they open their mouths widely. As a rule, or at least very often, when flying, they do not begin their songs until they have almost reached the apex of their triangle; then the song begins, and it continues over the angle and down the incline until another perch is settled upon. What Lowell says of "bobolink.u.m" is just as true of bunting--"He runs down, a brook o' laughter, thru the air." As the sun went down behind the snow-clad mountains, a half dozen or more of the buntings rolled up the full tide of song, and I left them to their vespers and trudged back to the village, satisfied with the acquirements of this red-letter day in my ornithological journey.

However, one afternoon's study of such charming birds was not enough to satisfy my curiosity, for no females had been seen and no nests discovered. About ten days later, more attention was given them. In a meadow not far from the hamlet of Arvada, between Denver and the mountains, I found a colony of buntings one morning, swinging in the air and furnis.h.i.+ng their full quota of the matutinal concert, in which many other birds had a leading part, among them being western meadow-larks, western robins, Bullock's orioles, American and Arkansas goldfinches, mountain song-sparrows, lazuli finches, spurred towhees, black-headed grosbeaks, summer warblers, western Maryland yellow-throats, and Townsend's solitaires. It has seldom been my fortune to listen to a finer _pot-pourri_ of avian music.

At first only male buntings were seen. Surely, I thought, there must be females in the neighborhood, for when male birds are singing so l.u.s.tily about a place, their spouses are usually sitting quietly on nests somewhere in bush or tree or gra.s.s. I hunted long for a nest, trudging about over the meadow, examining many a gra.s.s-tuft and weed-clump, hoping to flush a female and discover her secret; but my quest was vain.

It is strange how difficult it is to find nests in Colorado, either on the plains or in the mountains. The birds seem to be adepts in the fine arts of concealment and secret-keeping. Presently several females were seen flying off over the fields and returning, obviously to feed their young. There was now some colorable prospect of finding a nest. A mother bird appeared with a worm in her bill, and you may rely upon it I did not permit her to slip from my sight until I saw her drop to the ground, hop about stealthily for a few moments, then disappear, and presently fly up minus the worm. Scarcely daring to breathe, I followed a direct course to the weed-clump from which she had risen. And there was a nest, sure enough--my first lark bunting's--set in a shallow pit of the ground, prettily concealed and partly roofed over by the flat and spreading weed-stalk. Four half-fledged youngsters lay panting in the little cradle, the day being very warm. I lifted one of them from the nest, and held it in my hand for a minute or two, and even touched it with my lips, my first view of lark-bunting babies being something of an event--I had almost said an epoch--in my experience. Replacing the youngster in its crib, I stepped back a short distance and watched the mother bird returning with another mouthful of "goodies," and feeding her bantlings four. She was not very shy, and simply uttered a fine chirp when I went too close to her nestlings, while her gallant consort did not even chirp, but tried to divert my attention by repeatedly curveting in the air and singing his choicest measures. This was the only bunting's nest I found, although I made long and diligent search for others, as you may well believe when I state that a half day was spent in gathering the facts recorded in the last two paragraphs.

In the afternoon I watched a female in another field for a long time, but she was too wary to betray her secret. In this case the male, instead of beguiling me with song, flitted about and mingled his fine chirps with those of his anxious mate. On my way across the plains, some two weeks later, I discovered that the lark buntings do not dwell only in well-watered meadows, but also in the most arid localities.

Still, I am inclined to think they do not build their nests far from refres.h.i.+ng streams. When the breeding season is over, they range far and wide over the plains in search of insects that are to their taste. From the car window many of them were observed all along the way to a distance of over sixty miles east of Denver. At that time the males, females, and young were moving from place to place, mostly in scattering flocks, the breeding season being past. A problem that puzzled me a little was where they obtain water for drinking and bathing purposes, but no doubt such blithe and active birds are able to "look out for number one."

The second member of our lyrical quartette is the elegant green-tailed towhee, known scientifically as _Pipilo chlorurus_. The pretty green-tails are quite wary about divulging their domestic secrets, and for a time I was almost in despair of finding even one of their nests.

In vain I explored with exhausting toil many a steep mountain side, examining every bush and beating every copse within a radius of many rods.

My purpose was to flush the female from her nest, a plan that succeeds with many birds; but in this instance I was disappointed. It is possible that, when an intruder appears in their nesting haunts, the males, which are ever on the lookout, call their spouses from the nests, and then "snap their fingers," so to speak, at the puzzled searcher.

However, by watching the mother birds carrying worms in their bills I succeeded in finding two nests. The first was at Breckenridge, and, curiously enough, in a vacant lot at the border of the town, not on a steep slope, but on a level spot near the bank of Blue River. The mother bird had slyly crept to her nest while I watched, and remained firmly seated until I bent directly over her, when she fluttered away, trailing a few feet to draw my attention to herself. It was a cosey nest site--in a low, thick bush, beneath a rusty but well-preserved piece of sheet-iron which made a slant roof over the cradle. It contained three callow bantlings, which innocently opened their carmine-lined mouths when I stirred the leaves above them. It seemed to be an odd location for the nest of a bird that had always appeared so wild and shy. The alt.i.tude of the place is nine thousand five hundred and twenty feet.

My second green-tail's nest was in South Platte Canon, near a station called Chaseville, its elevation being about eight thousand five hundred feet. I was walking along the dusty wagon road winding about the base of the mountain, when a little bird with a worm in her bill flitted up the steep bank a short distance and disappeared among the bushes. The tidbit in her bill gave me a clew to the situation; so I scrambled up the steep place, and presently espied a nest in a bush, about a foot and a half from the ground. As had been antic.i.p.ated, it turned out to be a green-tailed towhee's domicile, as was proved by the presence and uneasy chirping of a pair of those birds. While the nest at Breckenridge was set on the ground, this one was placed on the twigs of thick bushes, showing that these birds, like their eastern relatives, are fond of diversity in selecting nesting places.

This nest contained four bantlings, already well fledged. My notes say that their mouths were yellow-lined, and that the fleshy growths at the corners of their bills were yellow. Does the lining of the juvenile green-tail's mouth change from red to yellow as he advances in age? My notes certainly declare that the nestlings at Breckenridge had carmine-lined mouths. For the present I cannot settle the question either affirmatively or negatively.

Here I perpetrated a trick which I have ever since regretted. The temptation to hold a baby green-tail in my hand and examine it closely was so strong that, as carefully as I could, I drew one from its gra.s.sy crib and held it in my palm, noting the green tinting already beginning to show on its wings and back. Its tail was still too stubby to display the ornamentation that gives the species its popular name. So much was learned, but at the expense of the little family's peace of mind. As I held the bantling in my hand, the frightened mamma uttered a series of pitiful calls that were new to my ears, consisting of two notes in a low, complaining tone; it was more of an entreaty than a protest.

Afterwards I heard the green-tails also give voice to a fine chirp almost like that of a chipping sparrow.

The mother's call seemed to strike terror to the hearts of her infant brood, for, as I attempted to put the baby back into its crib, all four youngsters set up a loud to-do, and sprang, panic stricken, over the rim, tumbling, fluttering, and falling through the network of twigs to the ground, a couple of them rolling a few feet down the dusty bank.

Again and again I caught them and put them back into the nest, but they would not remain there, so I was compelled to leave them scrambling about among the bushes and rocks. I felt like a buccaneer, a veritable Captain Kidd. My sincere hope is that none of the birdkins came to grief on account of their premature flight from the nest. The next morning old and young were chirping about the place as I pa.s.sed, and I hurried away, feeling sad that science and sentiment must sometimes come into conflict.

One day in the latter part of June, as I was climbing the steep side of a mesa in the neighborhood of Golden, my ear was greeted by a new style of bird music, which came lilting sweetly down to me from the height. It had a kind of wild, challenging ring about it, as if the singer were daring me to venture upon his demesne at my peril. A hard climb brought me at length within range of the little performer, who was blowing his Huon's horn from the pointed top of a large stone on the mesa's side. My field-gla.s.s was soon fixed upon him, revealing a little bird with a long beak, decurved at the end, a grayish-brown coat quite thickly barred and mottled on the wings and tail, and a vest of warm white finely sprinkled with a dusky gray. A queer, shy, timid little thing he was. Afterwards I met him often, but never succeeded in gaining his confidence or winning a single concession from him. He was the rock wren (_Salpinctes obsoletus_)--a species that is unknown east of the Great Plains, one well deserving a place in literature.

I was especially impressed with his peculiar style of minstrelsy, so different from anything I had ever heard in the bird realm. While the song was characterized by much variety, it usually opened with two or three loud, clear syllables, somewhat prolonged, sounding, as has been said, like a challenge, followed by a peculiar bubbling trill that seemed fairly to roll from the piper's tongue. Early one morning a few days later I heard a brilliant vocalist descanting from the top of a pump in a wide field among the foothills. How wildly his tones rang out on the crisp morning air! I seemed to be suddenly transported to another part of the world, his style of music was so new, so foreign to my ear.

My pencilled notes say of this particular minstrel: "Very musical--great variety of notes--clear, loud, ringing--several runs slightly like Carolina's--others suggest Bewick's--but most of them _sui generis_."

Let us return to the first rock wren I saw. He was exceedingly shy, scurrying off to a more distant perch--another stone--as I approached.

Sometimes he would run down among the bushes and rocks like a mouse, then glide to the top of another stone, and fling his pert little aria at the intruder. It was interesting to note that he most frequently selected for a singing perch the top of a high, pointed rock where he could command a view of his surroundings and pipe a note of warning to his mate at the approach of a supposed enemy. Almost every conspicuous rock on the acclivity bore evidence of having been used as a lookout by the little sentinel.
