Plate XXXIX. OXYECHUS VOCIFERUS, (Linn.) Reich. Killdeer.

Previous

The above species is one of the most abundant, the most widely distributed, as well as the best known of all our Plovers. It is a denizen of the whole of temperate North America, where suitable localities abound, and, unlike the most of its kin, breeds pretty generally in the United States. Throughout the Missouri region, and even as far west as Salt Lake, Utah, it has been observed by parties connected with the different exploring expeditions of the National Government. It is found in the West Indies, and in the fall extends its migrations into Central and South America, where it passes the winter. These journeys are chiefly performed at night, not quietly, however, but with considerable clamor. In the time of Wilson it never entirely deserted the United States during the season of snow and ice, but retired to the seashore, where it managed to eke out an existence. No sooner had the rivers been released from their icy fetters than their shrill cries would be heard as they wended their way high overhead, or nestled among the partially submerged meadows that lined their banks. This was mainly the case in the South Atlantic States, where, amid the rice-fields they were to be seen in February and March.

With the return of mild weather our Southern friends, having their ranks possibly swollen by fresh accessions from sunnier climes, diffuse themselves over the higher latitudes. While some remain in the vicinity of the sea, and establish their homes in dry, sandy fields, the majority, as though tired of its wearisome monotone, strike for the interior, and lay claim to a piece of newly ploughed ground, or to some low stretch of laud, devoid of vegetation, and covered with shallow pools. Their arrival in the old haunts generally dates from the twentieth of April to about the middle of May, and is quite true to time in any given locality. For a short time subsequent thereto the sexes are concerned with the procurement of food, and may be observed wading knee-deep in the water of gravelly brooks and sandy streams for aquatic insects which contribute largely to their maintenance. While fond of such pursuits, the inclination to bathe within the limpid element to which they resort, is one which they cannot very well resist, for these ablutions are of frequent daily occurrence, and are enjoyed with great satisfaction. When disengaged from such occupations, they squat upon the ground, or stand erect upon both legs. If disturbed they seek to escape by running, or by vigorous application of the wings. Their alarm, on these occasions, is best shown by the peculiar cries of killdeer, kildeer which they emit. These expressions are sometimes varied to te te de dit, or simply te dit.

When the sexes have grown weary of surfeiting, they seem to come together by common consent, and, without much pomp or show, enter into marital relations. The union thus formed is one of purest devotion, based upon mutual sympathy and affection. Jealous of his spouse, the male throws around her his aegis of protection, and stands ready to wreak vengeance upon any of his feathered brethren who should dare intrude upon her presence, or offer her the slightest insult. While thus regardful of her honor, he is none the less thoughtful of her comfort and wants, and seems ever ready to obey her slightest mandates, whether expressed by word or gesture. When she is ready to nestle, he accompanies her in her explorations, and assists in the selection of a site for a home. This business is seldom delayed later than the middle of May, and, although of immense moment, is protracted but for a brief period. The spot chosen for a nest is a barren field by the seaside, a piece of ploughed ground, or some pool-ridden, grass-lacking plain in the interior. The nest is usually a slight hollow, and is lined with bits of grass, straw, sea-weed, pebbles, or such other substances as may be convenient to the builders. In some cases the birds evidently go to considerable trouble, and manifest a taste for the beautiful. A case in point is given by Wilson. In one of his travels he came across a nest that was literally paved with oyster and clam shells, and which, in addition, was neatly surrounded by a wall of the same, closely and curiously arranged. These birds were doubtless possessed of higher mental capacities than are common to their tribe, or they would not have gone to so much pains to beautify and improve their domicile. Again, nests are often found which do not show the least vestige of a lining. Scarcity of materials, or absolute lack thereof, might be offered as an explanation of the circumstance, but we have observed such apparently incomplete abodes in situations where there could have been no difficulty in procuring the necessary articles. Such-a simple affair, as the nest ordinarily is, cannot certainly occupy the builders for any great length of time. Consequently, we find that the female is ready to commence laying on the day succeeding the establishment of her home. Her complement of eggs being but four, usually at the expiration of the fourth day, she is prepared to incubate. Like most birds that lay their eggs in similar situations, the heated sand or pebbles have much to do with the hatching-process. This is presumably the case in fair weather. On cloudy days, during stormy weather, and at nights, it is necessary that they should be covered. Upon the female devolves this duty, and right cheerfully does she assume it. The time required to hatch the eggs depends upon various circumstances, such as seasonal warmth, condition of weather, and devotion of the sitting-bird. At any rate, in about sixteen days from the time of the deposit of the last egg, the young birds are ready to appear. Their deliverance is hailed with joy. Nothing can exceed the attachment of the parents to their charges. Let the nest be approached by a person, and the birds resort to various expedients to draw him away from the spot, or to infuse a feeling of fear into his bosom. They beat the air above his head with swiftly-plying pinions, or run along the ground with counterfeited lameness, uttering incessantly and loudly their shrill, but unmistakable call-notes. These movements are kept up for a long time, until the enemy is led over considerable scope of country, and the young are safe in places of concealment. The latter are fed upon insects of various kinds which the birds obtain in places they visit. Besides those which inhabit water, grasshoppers, crickets, beetles, worms, etc., form a large percentage of their food. Being somewhat crepuscular in habit, not many of the insects which affect twilight escape their close scrutiny.

The young are soon able to take care of themselves, but instead of deserting the family-circle when arrived at the age of responsibility in bird-life, they continue to frequent the same haunts with their parents, and, at the close of summer, descend with them to the seashore (thus constituting the small flocks which we then observe), or retire with them beyond our borders, to try their fortunes in brighter and more prolific regions. Whether they attain the adult plumage in the autumn, or in the following spring, it is not in our power to say; but when the birds make their appearance during the latter season, it is difficult to distinguish the young from their older brethren. By referring to the picture a strong similarity will be found to exist between the sexes. The rump and upper tail-coverts are of an orange-brown color; the tail feathers are white at base and tip, with a suffusion of orange-brown for a portion of their length, and marked with from one to three black bars. The secondary wing-feathers are mostly white, while the primaries have simply a white space. There is a black band across the forehead, and two broader ones on the neck and breast. The bill is black, and the feet pale grayish-blue. The length is about ten inches, wing six, and tail three and one-half.

The eggs are pyriform in shape, somewhat elongated, creamy-buff in ground, and marked with numerous speckles, blotches and scratches of a dark-brown color, which are larger and more generally distributed around the greater end, although abundant over the entire surface. The actual measurements of a set before us are as follows: 1.53 by 1.05, 1.50 by 1.06, 1.45 by 1.04, and 1.43 by 1.09 inches, giving an average size of 1.48 by 1.06 to an egg. The species is single-brooded.
