Nests and Eggs of Birds of The United States. Gentry Thomas George
and fine dots of red-brown, which are chiefly found at the larger extremity. But a single brood is raised, although nests with eggs have been taken early in July, which must be attributed to birds whom accident or design had prevented from obeying their natural instincts earlier.
Plate XI. – TRINGOIDES MACULARIUS, Gray. – Spotted Sandpiper
The Spotted Sandpiper has an extended and varied distribution throughout North America. Unlike most of its allies, it breeds with equal readiness wherever found, and is one of the best known and most abundant of all its tribe.
From its winter-quarters in the Southern States, and also in the West Indies and Central and South America, to Brazil, it takes up the line of migration about the tenth of April, and gradually spreads itself over nearly the whole country as far north as Labrador and Fort Yukon.
According to Mr. Trippe, it is the only species of its family that resorts to the mountains of Colorado. Here, it arrives early in May, and departs in September. All the larger streams, to an altitude of 8,000 or 9,000 feet, are visited, and, even, in some instances, the shores of the lakes near the timber line.
On their first arrival, the banks of large rivers are frequented; but as the season advances, many trace their way into the interior, along the courses of our creeks and rivulets. Their sole object now is the acquirement of food. For this purpose, a life of solitude is preferable to any other. Although three or four individuals may frequently be discovered together upon the same feeding-grounds, yet careful and repeated observations have convinced us that this occurrence is merely accidental, and not dictated by a desire for company. At such times, the birds become so deeply absorbed in the business before them, that the approach of human beings is unobserved, and the actors are only aroused from the stolidity and indifference into which they have fallen, by the crackling of a dead branch, or the dislodgment of a pebble from its mooring. Conscious of impending danger, but never stopping to inquire into the cause of the alarm, they seek safety in instant flight, and repair to other scenes, at no great distance from the former, whore they think to pursue their gastronomic occupation without fear of being molested.
Such are the colors of this species, that the utmost harmony obtains between them and the hues of surrounding objects. The keen eye of the practised sportsman is often eluded thereby. Were it not for its peculiar habit of wagging the tail, it would be a very difficult bird to locate, especially when in a standing attitude; for whether thus occupied, or running on the ground, or along the rails of a fence, or in the water, this motion seems continual. Even the young, as soon as they are released from the shell, are taught by instinct the same remarkable movement.
Usually about the third week from the time of their first appearance, but sometimes later, the sexes, grown corpulent from good feeding, discard in a measure the "joys of the table," and seek each other's society. From stilly bank of inland pond or stream, or where old Neptune lashes in frenzied mood his solid flanks, their strange and simple call, peet-iveet, peet-weet, may be heard in quick succession, louder, and more distinct, than was their wont. Nor do the males alone indulge therein; for the gentler sex oft join their lords in wanton rivalry.
Less whimsical than their aristocratic neighbors who affect the tall tree-tops and shady bushes, the lady Sandpipers are more easily wooed and won. Their ardent lovers have but to make their suits with due obsequiousness, to receive the courted promises. A few more avowals of love, and caresses, and the necessary reciprocations on the part of the females, and the happy lovers having sealed their plighted pledges in a bond of union, the respective parties journey off in search of suitable places for establishing their homes. This event generally occurs about the last of May, in some localities, but sometimes not earlier than the second week of June, in others, and, perhaps, later in the extreme northern limits of its habitat.
A period of three or four days being spent in examining the surrounding country, the various parties soon settle upon localities. While some prefer the borders of ponds and streams, or more retired and secluded situations in the midst of forests, or a corn-field on elevated ground, others, again, have a hankering for low, sandy islands, or marshes by the sea-coast, or even the almost barren beach itself.
This part of the business being attended to, each female begins to construct her nest. For this purpose she scratches a slight hollow in the sandy earth, and proceeds to line it with a few pieces of straw, or moss, or sea-weed, the nature of the materials depending upon the environment. When the nest is placed in a corn-field, it is generally built at the root of a hill of Indian corn, and is either lined with straws, or mosses; when upon the seashore, various species of algae are used.
Having finished her rather simple and hastily-constructed home, with as little delay as possible the female commences to deposit her complement of four eggs. This she does at the rate of one egg a day, in as many consecutive days, taking due care to place them with the small ends together in the middle of the nest.
The last egg deposited, the female, on the day thereafter, enters the nest, and commences the duty of incubation. She is not necessarily a very close sitter, especially when her nest is located in a sandy soil, as the heated sand has doubtless much to do with the development of the young. During inclement weather, protection is absolutely essential; consequently, one bird or the other must occupy it, by turns, until the necessity has passed.
While one is incubating, it does not appear that her partner is compelled to play the part of a purveyor of food. Careful examinations have never enabled us to detect the least evidence thereof. When either party is tired, or is severely pressed by hunger, the other is summoned to the spot, to receive the charge of affairs. Thus the business goes on for eighteen weary days, when the happy parents are blessed with a jolly little family.
The young are not the mere helpless creatures such as we have all along been describing, but as active beings, for the age, as it is possible to conceive of. Clad in silken robes of drab, with beautiful stripes of black adown the back, they constitute a merry, rollicking group of birdies. The world to them is a paradise of beauty, and a garden-spot of pleasure. As soon as they leave the shell, they run with remarkable speed, and otherwise exhibit a precocity which seems unnatural at that period of life. Feeding, like running, is instinctive. It cannot be that it is learned by imitation, any more than the exercise of the cursorial powers can be said to be thus acquired.
Although much of the trouble and care which birds generally bestow upon their offspring are thus saved to these fortunate parents, yet the power to discriminate between bad and good food, has to be learned by attention to the commands and actions of wiser heads. The young are not slow to profit from parental suggestions and instruction, for we find them, at the expiration of a fortnight, engaged in foraging with the judgment and adroitness of adults.
Few species exhibit symptoms of greater distress than these Sandpipers when their breeding-grounds are approached by human beings. The parents resort to every conceivable stratagem in order to draw the intruders away. Counterfeiting lameness, and fluttering along the ground with seeming difficulty, are two of the most characteristic devices which they practise for this purpose. But the appearance of a dog considerably heightens the agitation. It is very interesting to watch the actions of the female on such occasions. In order to lead him away from her terrified young, she throws herself before him, flutters away in a contrary direction, but always managing to keep out of the reach of danger. This she continues for some time, until the animal has been drawn to a considerable distance, when she throws off the garb of dissimulation, and takes to flight, leaving her pursuer standing stock-still and gazing with astonishment and disappointment at the remarkable transformation which has just been effected. While all this has been going on, the young have scurried away to places of shelter and security, where they are afterwards joined by their beloved parent, glad to have escaped so fearful a calamity, and grateful for such a happy deliverance.
A more substantial proof of the affection of this female for its young could hardly be imagined than that which Wilson gives on the authority of Mr. William Bartram. The scene of action is described as being on the river shore, and the occasion, the repeated attempts made by a ground squirrel to capture two young birds which a parent was trying to defend. In order to ward off the assaults of the squirrel, she had thrown her two young behind her. At every attempt of the animal to seize them by a circuitous sweep, she would raise her wings almost perpendicularly, assume
