AMERICAN GREEN-WINGED TEAL.
|Genus||ANAS CAROLINENSIS, Steph.
Nothing can be more pleasing to an American sportsman, than the arrival of this beautiful little Duck in our Southern or Western States. There, in the
month of September, just as the sun sinks beneath the horizon, you may find him
standing on some mote or embankment of a rice-field in Carolina, or a neck of
land between two large ponds in Kentucky, his gun loaded with number four, and
his dog lying at his feet. He sees advancing from afar, at a brisk rate, a
small dark cloud, which he has some minutes ago marked and pronounced to be a
flock of Green-winged Teals. Now be squats on his haunches; his dog lies close;
and ere another minute has elapsed, right over his head, but too high to be shot
at, pass the winged travellers. Some of them remember the place well, for there
they have reposed and fed before. Now they wheel, dash irregularly through the
air, sweep in a close body over the watery fields, and in their course pass near
the fatal spot where the gunner anxiously awaits. Hark, two shots in rapid
succession! The troop is in disorder, and the do, dashes through the water.
Here and there lies a Teal, with its legs quivering; there, one is whirling
round in the agonies of death; some, which are only wined, quickly and in
silence make their way towards a hiding-place, while one, with a single pellet
in his head, rises perpendicularly with uncertain beats, and falls with a splash
on the water. The gunner has charged his tubes, his faithful follower has
brought up all the game, and the frightened Teals have dressed their ranks, and
flying now high, now low, seem curious to see the place where their companions
have been left. Again they fly over the dangerous spot, and again receive the
double shower of shot. Were it not that darkness has now set in, the carnage
might continue until the sportsman should no longer consider the thinned flock
worthy of his notice. In this manner, at the first arrival of the Green-winged
Teal in the Western Country, I have seen upwards of six dozen shot by a single
gunner in the course of one day.
I have often thought that water-birds, Ducks for example, like land-birds which migrate in flocks, are very apt to pass over the place where others of the same kind had been before. Pigeons, Starlings, Robins, and other land-birds are often observed to do so; while Curlews, Cormorants, Plovers, Ducks and Geese, are similar in this respect. The first object in view with such species is to remove from one part of the country to another, as every one knows; and as to reach a place of safety abundantly supplied with food, is the next object, you may perhaps join me in concluding, that, to the spot or district in which birds have once been and spent a season, they are ever afterwards inclined to return. Well, the Green-wings are known to follow each other in flocks, sometimes consisting of a few families, sometimes of many hundred individuals, particularly in autumn, when old and young leave the north to avoid the rigours of its dreary winter. In spring, again, many species both of land and water birds perform their migrations, either singly or in smaller groups, the males departing before the females, and in some cases the young keeping by themselves, an arrangement perhaps intended for the greater dispersion of the species.
In Louisiana, the Green-winged Teal is named Sarcelle d'hiver, while the Blue-winged species bears the name of Sarcelle d'ete, although the latter remains only some weeks in that country after the departure of the former. Its general name, however, is the "Green-wing;" and a poor name in my opinion it is, for the bird has not more green on its wings than several other species have. Indeed, very many birds are strangely named, not less in pure Latin, than in English, French, and Dutch; and very many are every year receiving names still stranger than those they bore. For my part, I am at present a kind of conservative, and adhere to the old system until I see the mud raised up by the waders subside, when I may probe my way with more chance of success.
The Green-winged Teal is a fresh-water bird, being rarely met with in marine bays, creeks, or lagoons, where, however, it may sometimes spend a few days. It is accordingly enabled to feed with its body half immersed, in the manner of the Mallard and several other species, for which purpose it is furnished with a comparatively long neck. Its food consists principally of the seeds of grasses, which are collected either when floating or when still adhering to their stalks, small acorns, fallen grapes or berries, as well as aquatic insects, worms, and small snails. I have never found water lizards, leeches, fishes, or even tadpoles in their gizzards. The food of this bird being thus more select than that of most other Ducks, its flesh is delicious, probably the best of any of its tribe; and I would readily agree with any epicure in saying, that when it has fed on wild oats at Green Bay, or on soaked rice in the fields of Georgia and the Carolinas, for a few weeks after its arrival in those countries, it is much superior to the Canvass-back in tenderness, juiciness, and flavour. Indeed, the Green-wing is as much superior to the Canvass-back, as the European Quail is to the Capercailie, or the Sora of the Delaware to the Scolopaceous Courlan of the Florida everglades.
On land, the Green-wing moves with more ease and grace than any other species with which I am acquainted, excepting our beautiful Wood Duck. It can run at a good rate, without entangling its webbed feet, as many others do; and in this, too, there is a marked difference between fresh-water and salt-water Ducks, as one may very readily perceive. On the water, also, it moves with great ease, at times with considerable rapidity, and when not severely wounded, is able to dive in a very creditable manner. On wing it has no rivals among Ducks. Our two smaller Mergansers, however, are swifter, although they exhibit none of the graceful movements ever now and then shewn by the Green-wings, when coursing in the air over and around a pond, a river, or a large wet savannah. They rise from the water at a single spring, and so swiftly too, that none but an expert marksman need attempt to shoot them, if when starting they are many yards distant. While feeding, they proceed in a close body along the shores, or wherever the water is so shallow that they can reach the bottom with ease. In savannahs or watery fields intersected by dry ridges, they remove from one pool to another on foot, unless the distance is considerable; and in effecting the transit, they run so huddled together, as to enable a gunner to make great havoc among them. When the cravings of hunger are satisfied, they retire to some clean part of the shore, or a sand-bar, where they rest in perfect harmony, each individual composing its dress, and afterwards, with wings slightly drooping, placing its breast to the sun. There they remain for an hour or more at a time, some sound asleep, some dosing, but rarely without a trusty sentinel watching over their safety. In this manner they spend the winter months in the Southern and Western Countries. There, indeed, they are far more abundant than in our eastern districts, just because the climate is milder, the human population more dispersed, and the damp fields, meadows, and savannahs more abundant.
The migrations of this species are performed more over the land than along the borders of the sea; and it is probable that its principal breeding-places are in the interior of the Fur Countries; as it has been met there by Sir EDWARD PARRY, Sir JAMES ROSS, Dr. RICHARDSON, and other intrepid travellers. Some, however, remain on our great lakes, and I have seen individuals breeding on the banks of the Wabash, in Illinois, where I found a female and young, all of which I obtained. It was not far above Vincennes, in the month of July. On Lakes Erie and Michigan, nests containing eggs have also been found; but these may have been cases in which the birds were unable to proceed farther north, on account of wounds or other circumstances, or because of the early period at which they might have paired before the general departure of the flocks, a cause of detention more common in migratory birds than people seem to be aware of these opportunities, few as they were, have enabled me to see the kinds of places in which the nests were found, the structure of the nest, the number, size, and colour of the eggs; so that I have in so far been qualified to draw a comparison between our Green-winged Teal and that of Europe.
The Green-wings leave the neighbourhood of New Orleans in the end of February; but in the Carolinas they remain until late in March, at which time also they depart from all the places between the Atlantic and the States of Kentucky, Indiana, &c. Farther eastward I have seen this species as late as the 9th of May, when I shot a few not far from Philadelphia. As you advance farther along our coast, you find it more rare; and scarcely any are met with near the shores of the British provinces. In Newfoundland and Labrador, it is never seen. Its migrations southward, I am satisfied, extend beyond the United States; but their extreme limits are unknown to me. I have seldom seen it associate with other species, although I have frequently observed individuals on a pond or river not far from other Ducks. It is more shy than the Blue-winged Teal, but less so than most of our other fresh-water Ducks. Its voice is seldom heard during winter, except when a flock is passing over another that has alighted, when a few of the males call to the voyagers, as if to invite them to join them. Before they depart, however, they become noisy. Combats take place among the males; the females are seen coquetting around them, and most of the birds are paired before they leave us.
In the few instances in which I found the nest of this bird, and they were only three, it was not placed nearer the water than five or six yards, and I should not have discovered it had I not first seen the birds swimming or washing themselves near the spot. By watching them carefully I discovered their landing places, and on going up found a path formed, in a direct line among the rushes. In two cases I came so near the nest, as almost to touch the sitting bird as it rose affrighted. While it flew round me, and then alighted on the water, I viewed the nest, with perhaps more interest than I have felt on most occasions of a like nature. On a scanty bed of the bird's own down and feathers, supported by another of grasses, intermixed with mud and stalks of the plants around, raised to the height of four or five inches, I found seven eggs in one, nine in another, and only five in a third. They were all found in the month of July, and not far from Green Bay. The average measurement of the eggs was an inch and three quarters by an inch and three-eighths. They were much rounded, of a dull yellowish colour, indistinctly marked with a deeper tint, as if soiled. In one of the nests only the eggs were fresh. I took two of them, which I afterwards ate. Having planted a stick as a mark of recognition, I visited the nest three days in succession, but found that the bird had abandoned it; while those of the other two nests, which were not more than about a hundred yards distant, and whose eggs I had handled quite as much, although I took none away, continued to sit. No male birds were to be seen during my stay in that neighborhood. I concluded that although the eggs may be touched or even handled and lifted from the nest, yet if they were all replaced, the bird did not take umbrage; but that should any of them be missed, some strong feeling urged her to abandon the rest. Again I thought that as incubation had just commenced with this bird, she cared less about her eggs than the other two whose eggs contained chicks.
Having met with the young of this species only once, at a time when I was less aware of the necessity of noting observations in writing, I am unwilling to speak of their colours from recollection. All I can say is that I had great trouble in catching four of them, so cunningly did they hide in the grass, and so expert were they at diving.
