Plate XLI. ASTRAGALINUS TRISTIS, (Linn.) Cab. American Goldfinch

Previous

The range of the American Goldfinch is nearly co-extensive with the vast continent of North America. Its range seems to he, in a great measure, determined by the presence of the cottonwood, willow and the various compositaceous plants upon the seeds of which it largely depends for a living. From the Atlantic to the Pacific it is found, and northward from the Mexic borders to the fur countries of the British possessions. It is abundant both in Texas and the Indian Territory, but in the vicinity of Vera Cruz it seems to be a stranger, as no mention is made of it by Sumichrast. Dr. Newberry encountered it while passing through the inland portions of Oregon and California, remote from civilized life, and Dr. Cooper on the Columbia, and in maritime situations in close proximity to its mouth. Dr. Suckley was unable to find it about Puget Sound, although at infinite pains to discover its presence. Dr. Coues failed to meet with it in Arizona, and Mr. Ridgway was surprised at the notable scarcity of it in Central California. For the hot interior valleys of this State, as well as the cooler mountain ranges, it seems to affect great dislike, although it was observed by Ridgway to be nesting in the Uintah Mountains.

Generally, where it is found at all, it exists in great abundance. In some portions of its habitat it is not a permanent resident, but migrates southward with the approach of cold weather, only to resume its northern journey again with the recurrence of another spring. In British America it is a late summer visitor, and departs early in September. It is a migrant in the northern parts of New England, and the same may be true of places situated in corresponding latitudes, while in the southern districts it remains through the entire year. In Eastern Pennsylvania, if the weather be not extremely severe, paired individuals, and even flocks of a half-dozen or more, may be met with in sheltered localities. In early autumn larger bodies of birds are met with, and the same is true in April, when there is an increased supply of food. When the ground is covered with snow, and the trees laden with ice and sleet, they lead very nomadic lives, and are often compelled to seek the habitations of man where they freely mingle with the Snowbirds and Sparrows, to receive their share of refuse from the kitchen. They now become exceedingly tame, and can be approached without difficulty. While partaking of our hospitalities, this Finch disdains not its natural food. It will lay siege to a honeysuckle, if in fruit, and gorge itself to satiety—a berry for which it manifests great fondness. The seeds of the radish, and of the various species of amaranths and pigweeds that grow in our midst, are also sought after, and devoured in vast numbers. In woods various species of coniferous seeds, the mast of the black beech, and the seeds of grasses form an important part of its diet. When the red maples are in blossom, dozens of these birds will settle down in the trees, and feast for hours upon the tender stamens and pistils, and the small insects which are attracted thither. As the season advances, and the apple and cherry come into bloom, the same fate awaits them. To the gardener they are sources of annoyance. They visit the garden when the soil has been broken, apparently for the writhing, scampering beings unearthed, but avowedly for the freshly-sown, delicious salad-seeds, every grain of which they pilfer, unless driven away by force. Later on they revel in high life, for the dandelion, thistles and sunflowers have perfected their fruits. Although chiefly a granivorous species, the Goldfinch does not subsist entirely upon seeds, but destroys vast numbers of insects in all their different stages. Various measuring-worms, diptera, ants and plant-lice are destroyed, which, doubtless, largely-outweigh the mischief which they commit.

Late in April the large flocks dissolve into smaller ones. It is a common thing to see two males and one female in company, the former lavishing the most endearing attentions upon the latter, and both, simultaneously, regaling her with the sweetest music. Thus affairs go on for some time, when, out of pure mischief, she selects one of the suitors, and just as he begins to feel his bosom glow with self-satisfied pride, she turns her back upon him, and flies to the other, who all the while has been pouring his soul away in the ecstasies of song. These cruel flirtations are kept up for a couple of days before a final choice is effected. It seems to require great effort and condescension upon the part of the successful suitor to retain his hold upon her affections; for she is likely to waver in the interval of time between mating and nidification, and give her heart to another. The labors of nest-building so completely engross her thoughts, that the tendency to flirtation has not time to manifest itself, and soon disappears altogether.

The wedded couple, however, do not seem to be in much haste about nesting, but ramble over the country in search of food, ever and anon, as though seeking rest from labor, perching upon a tree-branch, where the male pours into the ear of his less-favored partner, with all the impassioned eloquence of his being, the story of his love. While thus engaged, he is wont to turn towards the object of his affection, as if to ascertain the effects of his well-chosen roundelay. A low, soft note, expressed by the dissyllabic word twË-yah, is her only response of recognition and approval. The song of the male is very difficult to convey in human language. It is loud and clear in intonation, and rivals the variously modulated strains of the Canary. Like the latter he has the faculty of lowering and raising the voice, so that one moment the notes seem borne from a great distance on the wings of gently-murmuring zephyrs, while the very next they ring out upon the air with tenfold greater volume of tone and intensity. In confinement he becomes exceedingly familiar and tractable, and with proper care soon becomes a valuable singer. A friend of ours once possessed a male which he reared from the nest.

This bird was taught to keep time with the lateral movements of the index finger, and to increase and decrease the volume of sound with the elevation and depression of the same. In a state of repose a simple twe, uttered softly and slowly at measured intervals, is its only note. While pillaging the garden these birds give expression to sounds which Nuttall has likened to 'mÀy-bÊ, 'mÂy-bÊ. In their quarrels, which commonly occur when small parties are on the wing, there is heard one loud, confused medley of discordant chirpings, which seems, as a recent writer once remarked, as though some were pleading for peace, while the others were clamorous for the fray.

About the fifteenth of June, sometimes as early as the middle of the preceding month, the birds settle down to the business which has brought them together. Some time is spent in the selection of a suitable tree, and in fixing upon a position. One tree after another is visited, before one is found which combines the requisites of shelter, security and convenience. When the birds make up their minds to build in an orchard, a pear-tree is usually their choice. In other situations a seeming preference is manifested for the maple and willow. Perhaps, any tree where numerous small branches radiate, nearly in the same circle, from a common stem, will be found to be available. The height of the nest above the ground is usually about fifteen feet. Occasionally, greater elevations are taken. Sometimes a horizontal branch with divergent twigs is chosen, instead of one that is nearly vertical.

Than the nest of the Thistle Bird, as this species is sometimes called, no more beautiful structure of the basket in form and the felted in texture is known to exist. In shape it is symmetrical, delicately and neatly woven, and skilfully and securely fastened to the forked twigs between which it is placed. In beauty of design, and elegance of finish, it is a perfect model of architectural skill. A structure before us from Philadelphia may be considered as typical. It is placed in a crotch, and held in situ by four small nearly upright branches, which are partially wrought into the fabric. The outside is composed of the tassels of the common chestnut, stems of knotweed, leaves, fragments of fungus, interwoven with an excess of flax-like fabrics and vegetable wool. The inside is lined with divers shreds of dandelion and thistle, neatly and compactly felted. The external diameter and height are each two and a half inches, and the cavity two at the rim and the same in depth.

A nest from Union County, Pa., nearly two hundred miles distant from the former locality, varies materially in size and in the character of composing materials. When found it was placed between two horizontal twigs joined at right angles to another, to which it was firmly attached by hempen fibres. On the right of the nest further security was afforded by a vertical twig, to which it was bound by similar cords. Fine roots of grasses, spiders' webs, cotton string, twisted and untwisted yellowish hempen cords, nicely and evenly felted, constituted the exterior. Within there was a lining of yellow rootlets and white horse-hairs, the latter in excess. The nest is hemispherical, and measures three inches in width, and the same in height. The cavity is two inches in diameter and of equal depth. This nest was discovered about the fifteenth of August, and contained a brood of tender fledglings.

Another fabric is somewhat exceptional in position. It rests upon a horizontal limb, and is still further supported by three inclined twigs on the one side, to which it is fastened by strings and the ravellings of colored cottony fabrics. The exterior is made of raw cotton, animal wool, hempen strings, vegetable fibres, rootlets of grasses, rather ingeniously interwoven. Interiorly there is a strange commingling of wool and horsehairs. The bottom of the cavity is hardly covered, the twig which forms the basis of the structure being clearly discernible. in external diameter it measures two and a half inches, and in depth but two; the width and depth of the cavity are identical, being about one and three-fourths inches.

In New England, according to Samuels, the nest of this species is built of soft strips of the cedar and grape-vine bark, which are elaborately woven into a compact structure around a deep hollow, which is softly lined with the down of thistles, and, occasionally, with a few feathers.

After the completion of the nest, which ordinarily requires the united efforts of both birds for six days to accomplish, the female, on the following day, begins to deposit her eggs. These to the number of five are laid at the rate of one a day. Incubation commences on the day subsequent to the last deposit, and lasts for ten days. This duty devolves exclusively upon the female. The only part which the male performs is the indirect one of providing his companion with suitable nourishment. When not thus engaged he cheers the tedium of her task by an agreeable ditty. By some writers he is considered more of a dandy than a family man, as he spends the greater portion of his time with his fellows in the pursuit of food, in the arrangement of his toilet, or in the pleasures of the bath. Our experience is different. While he takes no direct part in the incubating process, his affection for his mate, and his constant desire to please her, prove him to be, in every sense, a model companion. When their home is assailed, he does not sneak away, and allow his partner to bear the brunt of the battle to be waged in its defence, but comes boldly to the front, and with loud clamors, angry gesticulations, and wide open jaws, unites with her to expel the intruder. Where frequent interferences occur, the birds are often forced to forsake their nest, and seek other quarters. This perhaps will account for the fact that nests with eggs are sometimes found as late as the fifteenth of July, and others with young birds during the last week of August. Such delays are doubtless of common occurrence.

The destruction of a nest while incubation is progressing, most generally leads to the renewal of the attempt in some other place. The desire for offspring will often be found to triumph over the most insuperable difficulties. We have known instances where the same pair had been thwarted four times in succession, and as often renewed the attempt. An unfortunate male or female may sometimes be doomed to lead the life of a celibate, by reason of the scarcity of individuals of the opposite sex. Perhaps an event has occurred which has altered the status of affairs. A male has died, and his partner is compelled to break up house-keeping, or seek another. If she does the latter, her companion may be a widower, or one that has been unable to enter into matrimonial relations for the reasons already assigned. Not willing to father the responsibilities of another, the old home, and its once precious charges if there be any, must be abandoned, and another domicile constructed and peopled. The mating being effected, a suitable spot chosen, a home prepared, and the subsequent duties of oviposition and incubation successfully passed through, all of which requiring time, it is not remarkable that nests should be found so late in the season.

Coming back from this necessary digression, the young are from eleven to twelve days old when they leave the nest. The addition of a week or ten days to this period finds them sufficiently matured to attend to their own wants. At first they are fed by the parents upon various soft-bodied insects, which they glean from the branches and foliage of trees, but later on, butterflies and various species of andrena and halictus are brought to them. When able to provide for themselves, they consort with their parents, and subsist with them on various kinds of seeds and berries.

The young do not acquire their full plumage until the following spring. Their characteristic dress in the fall nearly resembles that of the adult female. It is reddish-olive above, and fulvous-yellow below. Across the coverts there are to be seen two broad bands, and broad edges of pale rufus to the last half of the secondaries. The female is yellowish-gray above, greenish-yellow below, and is devoid of the black on the forehead. The adult male has a bright gamboge-yellow dress, which is in a great measure relieved of its sameness by the black crown, wings and tail. A still further variegation is noticeable in the lesser wing-coverts, lower edges of the greater ones, ends of secondaries and tertiaries, inner margins of tail-feathers, upper and lower tail-coverts, and tibia, which are white. In the winter a yellowish-brown color replaces the yellow, the wings and tail become browner, and the black of the crown is lacking. The under parts take on an ashy-brown hue, which passes into white behind, and yellowish along the throat. The entire length of the mature birds is five and a quarter inches, while that of the wing is three.

The eggs of this species, when fresh, are white, with a slight roseate tinge. In blown specimens they show a faint bluish hue. Their nearest counterparts are Lawrence's Goldfinch, from which they are scarcely distinguishable. They are usually four in number, although five sometimes occur, and in shape are oval. Their dimensions vary even in the same nest-full. Specimens from New England vary from .68 by .53 to .63 by 50 inches. Others from California measure .60 by 50. Pennsylvania eggs have an average measurement of .66 by .53. Considerable diversity of opinion exists as to the number of broods annually raised. Nuttall alleges that they raise two, but seems to base his assertion upon the fact that nests are found from the first of July to the middle of September, which in our estimation is wholly accounted for by explanations given above. The mass of writers, however, differ from him, and believe the species to raise but a single brood annually. In Pennsylvania and New Jersey, we can safely say that not a single case has occurred to us of double-broodedness.

It may be thought strange that these birds should, as a rule, be so dilatory in their movements, so far as the assumption of matrimonial relations is concerned, being even behind the generality of our Warblers, which are not so well-adapted to the climate as they An explanation of the matter has been attempted by Dr. Brewer. He seems to think that the cause is attributable to the scarcity of proper aliment for the young in early summer. The greater abundance of insects found in July, especially in their larval stages, which must necessarily constitute a fair percentage of their diet at first, would seem to contradict such a statement. Our experience goes to show that more nests with young birds are found from the middle of June to about the tenth of July than at any subsequent period, just at the time when insect life riots in luxuriance.
