The soloist circled around and around in the upper air so long that I

grew dizzy watching him, and my eyes became blinded by the sun and the

glittering sky. How long he kept up his aerial evolutions, singing all

the while, I am unprepared to announce, for I was too much engrossed in

watching him to consult my timepiece; but the performance lasted so long

that I was finally obliged to throw myself on my back on the ground to

relieve the strain upon me, so that I might continue to follow his

movements. I venture the conjecture that the show lasted from fifteen to

twenty minutes; at least, it seemed that long to me in my tense state of

body and mind. Finally he shot down like an arrow, making my head fairly

whirl, and landed lightly on the ground, where he skipped about and

resumed his roundelay as if he had not performed an extraordinary feat.

This was certainly skylarking in a most literal sense. With the

exception of a similar exhibition by Townsend's solitaire--to be

described in the closing chapter--up in the neighborhood of Gray's Peak,

it was the most wonderful avian aeronautic exploit, accompanied with

song, of which I have ever been witness. It is odd, too, that a bird

which is so much of a groundling--I use the term in a good sense, of

course--should also be so expert a sky-scraper. I had listened to the

sky song of the desert horned lark out on the plain, but there he did

not hover long in the air.

The killdeer plovers are as noisy in the park as they are in an eastern

pasture-field, and almost as plentiful. In the evening near the village

a pair of western robins and a thieving magpie had a hard tussle along

the fence of the road. The freebooter was carrying something in his beak

which looked sadly like a callow nestling. He tried to hide in the

fence-corners, to give himself a chance to eat his morsel, but they were

hot on his trail, and at length he flew off toward the distant ridge.

Where did the robins build their nests? I saw no trees in the

neighborhood, but no doubt they built their adobe huts on a fence-rail

or in a nook about an old building. Not a Say's phoebe had we thus far

seen on this jaunt to the mountains, but here was a family near the

village, and, sure enough, they were whistling their likely tunes, the

first time I had ever heard them. While I had met with these birds at

Glenwood and in the valley below Leadville, they had not vouchsafed a

song. What is the tune they whistle? Why, to be sure, it is, "Phe-be-e!

phe-be-e! phe-e-e-bie!" Their voices are stronger and more mellifluent

than the eastern phoebe's, but the manner of delivery is not so

sprightly and gladsome. Indeed, if I mistake not, there is a pensive

strain in the lay of the western bird.

A few cowbirds, red-winged blackbirds, and spotted sandpipers were seen

in the park, but they are too familiar to merit more than casual

mention. However, let us return to Brewer's blackbirds. Closely as they

resemble the bronzed grackles of the East, there are some marked

differences between the eastern and western birds; the westerners are

not so large, and their manners and nesting habits are more like those

of the red-wings than the grackles. Brewer's blackbirds hover overhead

as you come into the neighborhood of their nests or young, and the males

utter their caveats in short squeals or screeches and the females in

harsh "chacks."

[Illustration: _Magpie and Western Robins_

"_They were hot on his trail_"]

The nests are set in low bushes and even on the ground, while those of

the grackles are built in trees and sometimes in cavities. To be exact

and scientific, Brewer's blackbirds belong to the genus _Icolecophagus_,

and the grackles to the genus _Quiscalus_. In the breeding season the

western birds remain in the park. That critical period over, in August

and September large flocks of them, including young and old, ascend to

favorite feeding haunts far above the timber-line, ranging over the

slopes of the snowy mountains engirdling their summer home. Then they

are in the heyday of blackbird life. Silverspot himself, made famous by

Ernest Thompson Seton, did not lead a more romantic and adventurous

life, and I hope some day Brewer's blackbird will be honored by a no

less effective biography.

What a to-do they make when you approach their outdoor hatchery! Yet

they are sly and diplomatic. One day I tried my best to find a nest with

eggs or bantlings in it, but failed, although, as a slight compensation,

I succeeded in discovering three nests from which the young had flown.

The old birds of both sexes 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 grass-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 grass 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-glass was turned upon

them, for they would at once cease their pretended search for insects in

the grass 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 grass 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 cocks, which are always on the alert, evidently give the

alarm to their sitting mates, which thereupon slip surreptitiously 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 grass, 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 grass, presently her chirping

ceased, and she disappeared.

Several minutes passed, 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 grass for some distance after I had last seen her. I

made my search in an ever-widening circle, and at length espied some dry

grass 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 grass, 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

flushing 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 altitudes. Our nomads may ascend by easy stages along the few

canyons 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 passes 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 dashing their brains out against the cliffs and crags

of the canyons 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 passes 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 Canyon,

adding no new birds to our list, but making some interesting

observations. At Cassel's a house-wren had built a nest on the veranda

of the hotel where people were sitting or passing 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 Cassel'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.

[Illustration: _Violet-green Swallow_

"_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

latitude 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 assuming 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 assert, were happier than the little white-crown in

her grassy lodge on the bank of the murmuring stream.

On the way down the canyon, 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 shore to shore,

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 publishing 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 analysis 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 rehearses 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 "bobolinkum" 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.
