"'What bird is that? Its song is good,' And eager eyes Go peering through the dusky wood In glad surprise; Then late at night when by his fire The traveller sits, Watching the flame grow brighter, higher, The sweet song flits By snatches through his weary brain To help him rest."
HELEN HUNT JACKSON: _The Way to Sing_.
BRIEF FOREWORD
With sincere pleasure the author would acknowledge the uniform courtesy of editors and publishers in permitting him to reprint many of the articles comprised in this volume, from the various periodicals in which they first appeared.
He also desires to express his special indebtedness to Mr. Charles E. Aiken, of Colorado Springs, Colorado, whose contributions to the ornithology of the West have been of great scientific value, and to whose large and varied collection of bird-skins the author had frequent access for the purpose of settling difficult points in bird identification. This obliging gentleman also spent many hours in conversation with the writer, answering his numerous questions with the intelligence of the scientifically trained observer. Lastly, he kindly corrected some errors into which the author had inadvertently fallen.
While the area covered by the writer's personal observations may be somewhat restricted, yet the scientific bird-list at the close of the volume widens the field so as to include the entire avi-fauna of Colorado so far as known to systematic students. Besides, constant comparison has been made between the birds of the West and the allied species and genera of our Central and Eastern States. For this reason the range of the volume really extends from the Atlantic seaboard to the parks, valleys, and plateaus beyond the Continental Divide.
L. S. K.
All are needed by each one; Nothing is fair or good alone. I thought the sparrow's note from heaven, Singing at dawn on the alder bough; I brought him home, in his nest, at even; He sings the song, but it cheers not now, For I did not bring home the river and sky;-- He sang to my ear,--they sang to my eye.
RALPH WALDO EMERSON: _Each and All_.
Not from his fellows only man may learn Rights to compare and duties to discern; All creatures and all objects, in degree, Are friends and patrons of humanity. There are to whom the garden, grove, and field Perpetual lessons of forbearance yield; Who would not lightly violate the grace The lowliest flower possesses in its place; Nor shorten the sweet life, too fugitive, Which nothing less than infinite Power could give.
WILLIAM WORDSWORTH: _Humanity_.
Sounds drop in visiting from everywhere-- The bluebird's and the robin's trill are there, Their sweet liquidity diluted some By dewy orchard spaces they have come.
JAMES WHITCOMB RILEY: _A Child World_.
Even in the city, I Am ever conscious of the sky; A portion of its frame no less Than in the open wilderness. The stars are in my heart by night, I sing beneath the opening light, As envious of the bird; I live Upon the payment, yet I give My soul to every growing tree That in the narrow ways I see. My heart is in the blade of grass Within the courtyard where I pass; And the small, half-discovered cloud Compels me till I cry aloud. I am the wind that beats the walls And wander trembling till it falls; The snow, the summer rain am I, In close communion with the sky.
PHILIP HENRY SAVAGE.
BIRDS OF THE ROCKIES
UP AND DOWN THE HEIGHTS
To study the birds from the level plains to the crests of the peaks swimming in cloudland; to note the species that are peculiar to the various altitudes, as well as those that range from the lower areas to the alpine heights; to observe the behavior of all the birds encountered in the West, and compare their habits, songs, and general deportment with those of correlated species and genera in the East; to learn as much as possible about the migratory movements up and down the mountains as the seasons wax and wane,--surely that would be an inspiring prospect to any student of the feathered fraternity. For many years one of the writer's most cherished desires has been to investigate the bird life of the Rocky Mountains. In the spring of 1899, and again in 1901, fortune smiled upon him in the most genial way, and--in a mental state akin to rapture, it must be confessed--he found himself rambling over the plains and mesas and through the deep cañons, and clambering up the dizzy heights, in search of winged rarities.
In this chapter attention will be called to a few general facts relative to bird life in the Rockies, leaving the details for subsequent recital. As might be expected, the towering elevations influence the movements of the feathered tenants of the district. There is here what might be called a vertical migration, aside from the usual pilgrimages north and south which are known to the more level portions of North America. The migratory journeys up and down the mountains occur with a regularity that amounts to a system; yet so far as regards these movements each species must be studied for itself, each having manners that are all its own.
In regions of a comparatively low altitude many birds, as is well known, hie to the far North to find the proper climatic conditions in which to rear their broods and spend their summer vacation, some of them going to the subarctic provinces and others beyond. How different among the sublime heights of the Rockies! Here they are required to make a journey of only a few miles, say from five to one hundred or slightly more, according to the locality selected, up the defiles and cañons or over the ridges, to find the conditions as to temperature, food, nesting sites, etc., that are precisely to their taste. The wind blowing down to their haunts from the snowy summits carries on its wings the same keenness and invigoration that they would find if they went to British America, where the breezes would descend from the regions of snow and ice beyond the Arctic Circle.
It will add a little spice of detail if we take a concrete case. There is the handsome and lyrical white-crowned sparrow; in my native State, Ohio, this bird is only a migrant, passing for the summer far up into Canada to court his mate and rear his family. Now remember that Colorado is in the same latitude as Ohio; but the Buckeye State, famous as it is for furnishing presidents, has no lofty elevations, and therefore no white-crowns as summer residents. However, Colorado may claim this distinction, as well as that of producing gold and silver, and furnishing some of the sublimest scenery on the earth; for on the side of Pike's Peak, in a green, well-watered valley just below timber-line, I was almost thrown into transports at finding the white-crowns, listening to their rhythmic choruses, and discovering their grass-lined nests by the side of the babbling mountain brook. Altitude accomplishes for these birds what latitude does for their brothers and sisters of eastern North America.
There is almost endless variety in the avi-faunal life of the Rockies. Some species breed far above timber-line in the thickets that invade the open valleys, or clamber far up the steep mountain sides. Others ascend still higher, building their nests on the bald summits of the loftiest peaks at an altitude of fourteen thousand feet and more, living all summer long in an atmosphere that is as rare as it is refreshing and pure. Among these alpine dwellers may be mentioned the brown-capped leucostictes, which shall be accorded the attention they deserve in another chapter. Then, there are species which have representatives both on the plains and far up in the mountain parks and valleys, such as the western robin, the western meadow-lark, and the mountain bluebird.
In this wonderful country there is to be observed every style of migratory habit. A twofold migrating current must be noticed. While there is a movement up and down the mountain heights, there is at the same time a movement north and south, making the migratory system a perfect network of lines of travel. Some species summer in the mountains and winter on the plains; others summer in the mountains pass down to the plains in the autumn, then wing their way farther south into New Mexico, Mexico, Central America, and even South America, where they spend the winter, reversing this order on their return to the north in the spring; others simply pass through this region in their vernal and autumnal pilgrimages, stopping for a short time, but spending neither the summer nor the winter in this latitude; still others come down from the remote north on the approach of autumn, and winter in this State, either on the plains or in the sheltering ravines and forests of the mountains, and then return to the north in the spring; and, lastly, there are species that remain here all the year round, some of them in the mountains, others on the plains, and others again in both localities. A number of hardy birds--genuine feathered Norsemen--brave the arctic winters of the upper mountain regions, fairly revelling in the swirling snow-storms, and it must be a terrific gale indeed that will drive them down from their favorite habitats toward the plains.
Does the avi-fauna of the Rocky Mountain district differ widely from that of the Eastern States? The reply must be made in the affirmative. Therefore the first work of the bird-student from the East will be that of a tyro--the identification of species. For this purpose he must have frequent recourse to the useful manuals of Coues and Ridgway, and to the invaluable brochure of Professor Wells W. Cooke on the "Birds of Colorado." In passing, it may be said that the last-named gentleman might almost be called the Colorado Audubon or Wilson.
In studying the birds of the West, one should note that there are western subspecies and varieties, which differ in some respects, though not materially, from their eastern cousins; for instance, the western robin, the western chipping sparrow, the western lark sparrow, and the western nighthawk. Besides, intermediate forms are to be met with and classified, the eastern types shading off in a very interesting process into the western. It would be impossible for any one but a systematist with the birds in hand to determine where the intermediate forms become either typical easterners or typical westerners.
Most interesting of all to the rambler on avian lore intent is the fact that there are many species and genera that are peculiar to the West, and therefore new to him, keeping him constantly on the _qui vive_. In Colorado you will look in vain for the common blue jay, so abundant in all parts of the East; but you will be more than compensated by the presence of seven other species of the jay household. The woodpeckers of the West (with one exception) are different from those of the East, and so are the flycatchers, the grosbeaks, the orioles, the tanagers, the humming-birds, and many of the sparrows. Instead of the purple and bronzed grackles (the latter are sometimes seen on the plains of Colorado, but are not common), the Rockies boast of Brewer's blackbird, whose habits are not as prosaic as his name would indicate. "Jim Crow" shuns the mountains for reasons satisfactory to himself; not so the magpie, the raven, and that mischief-maker, Clark's nutcracker. All of which keeps the bird-lover from the East in an ecstasy of surprises until he has become accustomed to his changed environment.
One cannot help falling into the speculative mood in view of the sharp contrasts between the birds of the East and those of the West. Why does the hardy and almost ubiquitous blue jay studiously avoid the western plains and mountains? Why do not the magpie and the long-crested jay come east? What is there that prevents the indigo-bird from taking up residence in Colorado, where his pretty western cousin, the lazuli finch, finds himself so much at home? Why is the yellow-shafted flicker of the East replaced in the West by the red-shafted flicker? These questions are more easily asked than answered. From the writer's present home in eastern Kansas it is only six hundred miles to the foot of the Rockies; yet the avi-fauna of eastern Kansas is much more like that of the Eastern and New England States than that of the Colorado region.
Perhaps the reason is largely, if not chiefly, physiological. Evidently there are birds that flourish best in a rare, dry atmosphere, while others naturally thrive in an atmosphere that is denser and more humid. The same is true of people. Many persons find the climate of Colorado especially adapted to their needs; indeed, to certain classes of invalids it is a veritable sanitarium. Others soon learn that it is detrimental to their health. Mayhap the same laws obtain in the bird realm.
The altitude of my home is eight hundred and eighty feet above sea-level; that of Denver, Colorado, six thousand one hundred and sixty, making a difference of over five thousand feet, which may account for the absence of many eastern avian forms in the more elevated districts. Some day the dissector of birds may find a real difference in the physiological structure of the eastern and western meadow-larks. If so, it is to be hoped he will at once publish his discoveries for the satisfaction of all lovers of birds.
If one had time and opportunity, some intensely interesting experiments might be tried. Suppose an eastern blue jay should be carried to the top of Pike's Peak, or Gray's, and then set free, how would he fare? Would the muscles and tendons of his wings have sufficient strength to bear him up in the rarefied atmosphere? One may easily imagine that he would go wabbling helplessly over the granite boulders, unable to lift himself more than a few feet in the air, while the pipit and the leucosticte, inured to the heights, would mount up to the sky and shout "Ha! ha!" in good-natured raillery at the blue tenderfoot. And would the feathered visitor feel a constriction in his chest and be compelled to gasp for breath, as the human tourists invariably do? It is even doubtful whether any eastern bird would be able to survive the changed meteorological conditions, Nature having designed him for a different environment.
INTRODUCTION TO SOME SPECIES
It was night when I found lodgings in the picturesque village of Manitou, nestling at the foot of the lower mountains that form the portico to Pike's Peak. Early the next morning I was out for a stroll along the bush-fringed mountain brook which had babbled me a serenade all night. To my delight, the place was rife with birds, the first to greet me being robins, catbirds, summer warblers, and warbling vireos, all of which, being well known in the East, need no description, but are mentioned here only to show the reader that some avian species are common to both the East and the West.
But let me pause to pay a little tribute to the brave robin redbreast. Of course, here he is called the "western robin." His distribution is an interesting scientific fact. I found him everywhere--on the arid plains and mesas, in the solemn pines of the deep gulches and passes, and among the scraggy trees bordering on timber-line, over ten thousand feet above sea-level. In Colorado the robins are designated as "western," forms by the system-makers, but, even though called by a modified title, they deport themselves, build their nests, and sing their "cheerily, cheerily, cheer up," just as do their brothers and sisters of the land toward the rising sun. If there is any difference, their songs are not so loud and ringing, and their breasts not quite so ruddy as are those of the eastern types. Perhaps the incessant sunshine of Colorado bleaches out the tints somewhat.
But in my ante-breakfast stroll at Manitou I soon stumbled upon feathered strangers. What was this little square-shouldered bird that kept uttering a shrill scream, which he seemed to mistake for a song? It was the western wood-pewee. Instead of piping the sweet, pensive "Pe-e-e-o-we-e-e-e" of the woodland bird of the Eastern States, this western swain persists in ringing the changes hour by hour upon that piercing scream, which sounds more like a cry of anguish than a song. At Buena Vista, where these birds are superabundant, their morning concerts were positively painful. One thing must be said, however, in defence of the western wood-pewee--he means well.
Another acquaintance of my morning saunter was the debonair Arkansas goldfinch, which has received its bunglesome name, not from the State of Arkansas, but from the Arkansas River, dashing down from the mountains and flowing eastwardly through the southern part of Colorado. Most nattily this little bird wears his black cap, his olive-green frock, and his bright yellow vest. You will see at once that he dresses differently from the American goldfinch, so well known in the East, and, for that matter, just as well known on the plains of Colorado, where both species dwell in harmony. There are some white markings on the wings of _Spinus psaltria_ that give them a gauze-like appearance when they are rapidly fluttered.
