Having explored the summit of Pike’s
Peak and part of its southern slope down to the timber-line,
and spent several delightful days in the upper valleys
of the mountains, as well as in exploring several canyons,
the rambler was desirous of knowing what species of
birds reside on the plain stretching eastward from
the bases of the towering ranges. One afternoon
in the latter part of June, I found myself in a straggling
village about forty miles east of Colorado Springs.
On looking around, I was discouraged,
and almost wished I had not come; for all about me
extended the parched and treeless plain, with only
here and there a spot that had a cast of verdure,
and even that was of a dull and sickly hue. Far
off to the northeast rose a range of low hills sparsely
covered with scraggy pines, but they were at least
ten miles away, perhaps twenty, and had almost as
arid an aspect as that of the plains themselves.
Only one small cluster of deciduous trees was visible,
about a mile up a shallow valley or “draw.”
Surely this was a most unpromising field for bird
study. If I had only been content to remain among
the mountains, where, even though the climbing was
difficult, there were brawling brooks, shady woodlands,
and green, copsy vales in which many feathered friends
had lurked!
But wherever the bird-lover chances
to be, his mania leads him to look for his favorites,
and he is seldom disappointed; rather, he is often
delightfully surprised. People were able to make
a livelihood here, as was proved by the presence of
the village and a few scattering dwellings on the
plain; then why not the birds, which are as thrifty
and wise in many ways as their human relatives?
In a short time my baggage was stowed in a safe place,
and, field-glass in hand, I sallied forth for my first
jaunt on a Colorado plain. But, hold! what were
these active little birds, hopping about on the street
and sipping from the pool by the village well?
They were the desert horned larks, so called because
they select the dry plains of the West as their dwelling
place. They are interesting birds. The fewer
trees and the less humidity, provided there is a spot
not too far away at which they may quench their thirst
and rinse their feathers, the better they seem to be
pleased. They were plentiful in this parched
region, running or flying cheerfully before me wherever
my steps were bent. I could not help wondering
how many thousands of them and millions,
perhaps had taken up free homesteads on
the seemingly limitless plains of eastern Colorado.
Most of the young had already left
the nest, and were flying about in the company of
their elders, learning the fine art of making a living
for themselves and evading the many dangers to which
bird flesh is heir. The youngsters could readily
be distinguished from their seniors by the absence
of distinct black markings on throat, chest, and forehead,
and the lighter cast of their entire plumage.
Sometimes these birds are called shore
larks; but that is evidently a misnomer, or at least
a very inapt name, for they are not in the least partial
to the sea-shore or even the shores of lakes, but are
more disposed to take up their residence in inland
and comparatively dry regions. There are several
varieties, all bearing a very close resemblance, so
close, indeed, that only an expert ornithologist can
distinguish them, even with the birds in hand.
The common horned lark is well known in the eastern
part of the United States as a winter resident, while
in the middle West, Missouri, Kansas, Nebraska, etc.,
are to be found the prairie horned larks, which, as
their name indicates, choose the open prairie for
their home. The desert horned larks are tenants
exclusively of the arid plains, mesas, and mountain
parks of the West. There is still another variety,
called the pallid horned lark, which spends the winter
in Colorado, then hies himself farther north
in summer to rear his brood.
As I pursued my walk, one of these
birds suddenly assumed an alert attitude, then darted
into the air, mounting up, up, up, in a series of
swift leaps, like “an embodied joy whose race
has just begun.” Up he soared until he
could no longer be seen with the naked eye, and even
through my field-glass he was a mere speck against
the blue canopy, and yet, high as he had gone, his
ditty filtered down to me through the still, rarefied
atmosphere, like a sifting of fine sand. His descent
was a grand plunge, made with the swiftness of an
Indian’s arrow, his head bent downward, his
wings partly folded, and his tail perked upward at
precisely the proper angle to make a rudder, all the
various organs so finely adjusted as to convert him
into a perfectly dirigible parachute. Swift as
his descent was, he alighted on the ground as lightly
as a tuft of down. It was the poetry of motion.
One or two writers have insisted that the horned lark’s
empyrean song compares favorably with that of the
European skylark; but, loyal and patriotic an American
as we are, honesty compels us to concede that our
bird’s voice is much feebler and less musical
than that of his celebrated relative across the sea.
It sounds like the unmelodious clicking of pebbles,
while the song of the skylark is loud, clear, and
ringing.
Our birds of the plain find insects
to their taste in the short grass which carpets the
land with greenish or olive gray. The following
morning a mother lark was seen gathering insects and
holding them in her bill a sure sign of
fledglings in the near neighborhood. I decided
to watch her, and, if possible, find her bantlings.
It required not a little patience, for she was wary
and the sun poured down a flood of almost blistering
heat. This way and that she scurried over the
ground, now picking up an insect and adding it to
the store already in her bill, and now standing almost
erect to eye me narrowly and with some suspicion.
At length she seemed to settle down for a moment upon
a particular spot, and when I looked again with my
glass, her beak was empty. I examined every inch
of ground, as I thought, in the neighborhood of the
place where she had stopped, but could find neither
nest nor nestlings.
Again I turned my attention to the
mother bird, which meanwhile had gathered another
bunch of insects and was hopping about with them through
the croppy grass, now and then adding to her accumulation
until her mouth was full. For a long time she
zigzagged about, going by provoking fits and starts.
At length fortune favored me, for through my levelled
glass I suddenly caught sight of a small, grayish-looking
ball hopping and tumbling from a cactus clump toward
the mother bird, who jabbed the contents of her bill
into a small, open mouth. I followed a bee-line
to the spot, and actually had to scan the ground sharply
for a few moments before I could distinguish the youngster
from its surroundings, for it had squatted flat, its
gray and white plumage harmonizing perfectly with
the grayish desert grass.
It was a dear little thing, and did
not try to escape, although I took it up in my hand
and stroked its downy back again and again. Sometimes
it closed its eyes as if it were sleepy. When
I placed it on the ground, it hopped away a few inches,
and by accident punctured the fleshy corner of its
mouth with a sharp cactus thorn, and had to jerk itself
loose, bringing the blood from the lacerated part.
Meanwhile the mother lark went calmly about her household
duties, merely keeping a watchful eye on the human
meddler, and making no outcry when she saw her infant
in my possession. I may have been persona
non grata, but, if so, she did not express her
feeling. This was the youngest horned lark seen
by me in my rambles on the plains.
Perhaps the reader will care to know
something about the winter habits of these birds.
They do not spend the season of cold and storm in the
mountains, not even those that breed there, for the
snow is very deep and the tempests especially fierce.
Many of them, however, remain in the foothills and
on the mesas and plains, where they find plenty
of seeds and berries for their sustenance, unless
the weather chances to be unusually severe. One
winter, not long ago, the snow continued to lie much
longer than usual, cutting off the natural food supply
of the larks. What regimen did they adopt in
that exigency? They simply went to town.
Many of the kindly disposed citizens of Colorado Springs
scattered crumbs and millet seeds on the streets and
lawns, and of this supply the little visitors ate
greedily, becoming quite tame. As soon, however,
as the snow disappeared they took their departure,
not even stopping to say thanks or adieu; although
we may take it for granted that they felt grateful
for favors bestowed.
Besides the horned larks, many other
birds were found on the plain. Next in abundance
were the western meadow-larks. Persons who live
in the East and are familiar with the songs of the
common meadow-lark, should hear the vocal performances
of the westerners. The first time I heard one
of them, the minstrelsy was so strange to my ear, so
different from anything I had ever heard, I was thrown
into an ecstasy of delight, and could not imagine
from what kind of bird larynx so quaint a medley could
emanate. The song opened with a loud, fine, piercing
whistle, and ended with an abrupt staccato gurgle
much lower in the musical staff, sounding precisely
as if the soloist’s performance had been suddenly
choked off by the rising of water in the windpipe.
It was something after the order of the purple martin’s
melodious sputter, only the tones were richer and
fuller and the music better defined, as became a genuine
oscine. His sudden and emphatic cessation seemed
to indicate that he was in a petulant mood, perhaps
impatient with the intruder, or angry with a rival
songster.
Afterwards I heard him or,
rather, one of his brothers sing arias
so surpassingly sweet that I voted him the master
minstrel of the western plains, prairies, and meadows.
One evening as I was returning to Colorado Springs
from a long tramp through one of the canyons of the
mountains, a western meadow-lark sat on a small tree
and sang six different tunes within the space of a
few minutes. Two of them were so exquisite and
unique that I involuntarily sprang to my feet with
a cry of delight. There he sat in the lengthening
shadows of Cheyenne Mountain, the champion phrase-fluter
of the irrigated meadow in which he and a number of
his comrades had found a summer home.
On the plain, at the time of my visit,
the meadow-larks were not quite so tuneful, for here
the seasons are somewhat earlier than in the proximity
of the mountains, and the time of courtship and incubation
was over. Still, they sang enough to prove themselves
members of a gifted musical family. Observers
in the East will remember the sputtering call of the
eastern larks when they are alarmed or their suspicions
are aroused. The western larks do not utter alarums
of that kind, but a harsh “chack” instead,
very similar to the call of the grackles. The
nesting habits of the eastern and western species are
the same, their domiciles being placed on the
ground amid the grass, often prettily arched over
in the rear and made snug and neat.
It must not be thought, because my
monograph on the western larks is included in this
chapter, that they dwell exclusively on the arid plain.
No; they revel likewise in the areas of verdure bordering
the streams, in the irrigated fields and meadows,
and in the watered portions of the upper mountain
parks.
An interesting question is the following:
Are the eastern and western meadow-larks distinct
species, or only varieties somewhat specialized by
differences of locality and environment? It is
a problem over which the scientific professors have
had not a little disputation. My own opinion
is that they are distinct species and do not cohabit,
and the conviction is based on some special investigations,
though not of the kind that are made with the birds
in hand. It has been my privilege to study both
forms in the field. In the first place, their
vocal exhibitions are very different, so much so as
to indicate a marked diversity in the organic structure
of their larynxes. Much as I have listened to
their minstrelsy, I have never known one kind to borrow
from the musical repertory of the other. True,
there are strains in the arias of the westerners
that closely resemble the clear, liquid whistle of
the eastern larks, but they occur right in the midst
of the song and are part and parcel of it, and therefore
afford no evidence of mimicry or amalgamation.
Even the trills of the grassfinch and the song-sparrow
have points of similarity; does that prove that they
borrow from each other, or that espousals sometimes
occur between the two species?
The habiliments of the two forms of
larks are more divergent than would appear at first
blush. Above, the coloration of neglecta
(the western) is paler and grayer than that of magna,
the black markings being less conspicuous, and those
on the tertials and middle tail-feathers being arranged
in narrow, isolated bars, and not connected along the
shaft. While the flanks and under tail-coverts
of magna are distinctly washed with buff, those
of neglecta are white, very faintly tinged with
buff, if at all. The yellow of the throat of
the eastern form does not spread out laterally over
the malar region, as does that of the western lark.
All of which tends to prove that the two forms are
distinct.
Early in the spring of 1901 the writer
took a trip to Oklahoma in the interest of bird-study,
and found both kinds of meadow-larks extremely abundant
and lavish of their melodies on the fertile prairies.
He decided to carry on a little original investigation
in the field of inquiry now under discussion.
One day, in a draw of the prairie, he noticed a western
meadow-lark which was unusually lyrical, having the
skill of a past-master in the art of trilling and gurgling
and fluting. Again and again I went to the place,
on the same day and on different days, and invariably
found the westerner there, perching on the fence or
a weed-stem, and greeting me with his exultant lays.
But, mark: no eastern lark ever intruded on his
preserve. In other and more distant parts of
the broad field the easterners were blowing their piccolos,
but they did not encroach on the domain of the lyrical
westerner, who, with his mate now on her
nest in the grass had evidently jumped his
claim and held it with a high hand. In many other
places in Oklahoma and Kansas where both species dwell,
I have noticed the same interesting fact that
in the breeding season each form selects a special
precinct, into which the other form does not intrude.
They perhaps put up some kind of trespass sign.
These observations have all but convinced me that
S. magna and S. neglecta are distinct
species, and avoid getting mixed up in their family
affairs.
Nor is that all. While both forms
dwell on the vast prairies of Oklahoma, Kansas, and
Nebraska, yet, as you travel eastward, the western
larks gradually diminish in number until at length
they entirely disappear; whereas, if you journey westward,
the precise opposite occurs. I have never heard
neglecta east of the Missouri River, nor
magna on the plains of Colorado. Therefore
the conclusion is almost forced upon the observer
that there are structural and organic differences
between the two forms.
After the foregoing deductions had
been reached, the writer bethought him of consulting
Ridgway’s Manual on the subject, and was gratified
to find his views corroborated by a footnote answering
to an asterisk affixed to the name of the western
lark:
“Without much doubt a distinct
species. The occurrence of both S. neglecta
and S. magna together in many portions of the
Mississippi Valley, each in its typical style (the
ranges of the two overlapping, in fact, for a
distance of several hundred miles), taken together
with the excessive rarity of intermediate specimens
and the universally attested radical difference
in their notes, are facts wholly incompatible
with the theory of their being merely geographical
races of the same species.”
This has been a long excursus,
and we must get back to our jaunt on the plain.
While I was engaged in watching the birds already named,
my ear was greeted by a loud, clear, bell-like call;
and, on looking in the direction from which it came,
I observed a bird hovering over a ploughed field not
far away, and then descending with graceful, poising
flight to the ground. It proved to be the Arkansas
flycatcher, a large, elegant bird that is restricted
to the West. I had never seen this species.
Nothing like him is known in the East, the crested
flycatcher being most nearly a copy of him, although
the manners of the two birds are quite unlike.
The body of the western bird is as large as that of
the robin, and he must be considerably longer from
tip of beak to tip of tail. He is a fine-looking
fellow, presenting a handsome picture as he stands
on a weed-stalk or a fence-post, his yellow jacket
gleaming in the sun. He is the possessor of a
clear, musical voice, and if he had the vocal organs
of some of the oscines, he certainly would be one of
the best feathered lyrists of America. Unfortunately
he is able to do nothing but chirp and chatter, although
he puts not a little music into his simple vocal exercises.
It was surprising to note on how slender
a weed-stalk so large a bird was able to perch.
There being few trees and fences in this region, he
has doubtless gained expertness through practice in
the art of securing a foot-hold on the tops of the
weed-stems. Some of the weeds on which he stood
with perfect ease and grace were extremely lithe and
flexible and almost devoid of branches.
But what was the cause of this particular
bird’s intense solicitude? It was obvious
there was a nest in the neighborhood. As I sought
in the grass and weed-clumps, he uttered his piercing
calls of protest and circled and hovered overhead
like a red-winged blackbird. Suddenly the thought
occurred to me that the flycatchers of my acquaintance
do not nest on the ground, but on trees. I looked
around, and, sure enough, in the shallow hollow below
me stood a solitary willow tree not more than fifteen
or twenty feet high, the only tree to be seen within
a mile. And that lone tree on the plain was occupied
by the flycatcher and his mate for a nesting place.
In a crotch the gray cottage was set, containing three
callow babies and one beautifully mottled egg.
In another fork of the same small
tree a pair of kingbirds the same species
as our well-known eastern bee-martíns had
built their nest, in the downy cup of which lay four
eggs similarly decorated with brown spots. The
birds now all circled overhead and joined in an earnest
plea with me not to destroy their homes and little
ones, and I hurriedly climbed down from the tree to
relieve their agitation, stopping only a moment to
examine the twine plaited into the felted nests of
the kingbirds. The willow sapling contained also
the nest of a turtle dove.
“If there are three nests in
this small tree, there may be a large number in the
cluster of trees beyond the swell about a mile away,”
I mused, and forthwith made haste to go to the place
indicated. I was not disappointed. Had the
effort been made, I am sure two score of nests might
have been found in these trees, for they were liberally
decorated with bird cots and hammocks. Most of
these were kingbirds’ and Arkansas flycatchers’
nests, but there were others as well. On one small
limb there were four of the dangling nests of Bullock’s
orioles, one of them fresh, the rest more or less
weather beaten, proving that this bird had been rearing
broods here for a number of seasons.
Whose song was this ringing from one
of the larger trees a little farther down the glade?
I could scarcely believe the testimony of my ears
and eyes, yet there could be no mistake it
was the vivacious mimicry of the mocking-bird, which
had travelled far across the plain to this solitary
clump of trees to find singing perches and a site for
his nests. He piped his musical miscellany with
as much good-cheer as if he were dwelling in the neighborhood
of some embowered cottage in Dixie-land. In suitable
localities on the plains of Colorado the mockers were
found to be quite plentiful, but none were seen among
the mountains.
A network of twigs and vines in one
of the small willows afforded a support and partial
covert for the nest of a pair of white-rumped shrikes.
It contained six thickly speckled eggs, and was the
first nest of this species I had ever found.
The same hollow, if so shallow a dip in
the plain can be called a hollow, was selected
as the home of several pairs of red-winged and Brewer’s
blackbirds, which built their grassy cots in the low
bushes of a slightly boggy spot, where a feeble spring
oozed from the ground. It was a special pleasure
to find a green-tailed towhee in the copse of the
draw, for I had supposed that he always hugged close
to the steep mountain sides.
A walk before breakfast the next morning
added several more avian species to my roll.
To my surprise, a pair of mountain bluebirds had chosen
the village for their summer residence, and were building
a nest in the coupler of a freight car standing on
a side track. The domicile was almost completed,
and I could not help feeling sorry for the pretty,
innocent couple, at the thought that the car would
soon be rolling hundreds of miles away, and all their
loving toil would go for naught. Bluebirds had
previously been seen at the timber-line among the
mountains, and here was a pair forty miles out on the
plain quite a range for this species, both
longitudinally and vertically.
During the forenoon the following
birds were observed: A family of juvenile Arkansas
flycatchers, which were being fed by their parents;
a half-dozen or more western grassfinches, trilling
the same pensive tunes as their eastern half-brothers;
a small, long-tailed sparrow, which I could not identify
at the time, but which I now feel certain was Lincoln’s
sparrow; these, with a large marsh-harrier and a colony
of cliff-swallows, completed my bird catalogue at
this place. It may not be amiss to add that several
jack-rabbits went skipping over the swells; that many
families of prairie dogs were visited, and that a coyotte
galloped lightly across the plain, stopping and looking
back occasionally to see whether he were being pursued.
It was no difficult task to study
the birds on the plain. Having few hiding-places
in a locality almost destitute of trees and bushes,
where even the grass was too short to afford a covert,
they naturally felt little fear of man, and hence
were easily approached. Their cousins residing
in the mountains were, as a rule, provokingly wary.
The number of birds that had pre-empted homesteads
on the treeless wastes was indeed a gratifying surprise,
and I went back to the mountains refreshed by the
pleasant change my brief excursion upon the plains
had afforded me.
