THE PINTAIL DUCK.
|Genus||ANUS ACUTA, Linn.
The first observation that I made on arriving at Labrador, was that no
species of Ducks, excepting those which were entirely or chiefly oceanic, seemed
to resort to that coast, and I left the country with the same impression. We
saw no Mallards, Teals, Widgeons, or Wood Ducks there; nor any species of
Merganser, excepting the Red-breasted, which is a marine bird. The Pintail
Duck, then, was not seen in the parts of that country which I visited; nor was
it known in Newfoundland, on the Magdeleine Islands, or in the British province
of Nova Scotia, at least along its Atlantic boundaries. In Kentucky and the
whole of the Western Country, where it is extremely abundant in early autumn,
during winter, and up to a very advanced period in spring, you meet with it
wherever its usual food is found. It follows the waters of the Mississippi to
New Orleans, is seen westward in the prairies of Oppelousas, and extends to the
eastward as far as Massachusetts, beyond which, like the Mallard, it is very
seldom seen. Indeed, this species is at all times rare on the sea coast of
America, and must therefore be considered as an inland bird.
The Pintail, which, in the United States, is better known by the name of Sprigtail, arrives on the western waters early in October, sometimes even about the middle of September, the period of its arrival depending on the state of the weather, or the appearance of other species, with which it keeps company. Their plumage is in fine condition when they arrive; their tailfeathers are then as long as at any other period, and the whole apparel of the adult birds is as perfect as in the breeding season.
On the water, few birds exhibit more graceful motions than the Pintail Duck. Its delicately slender neck, the beautiful form of its body, and its pointed tail, which it always carries highly raised, distinguish it from the other species with which it may associate. There seems also a kind of natural modesty in it which you do not find in other Ducks, and its notes, which are often heard, are soft and pleasant. That these notes should ever have been compared to those of the Mallard, appears to me very strange;--so strange that I am tempted to believe that they who say so must have mistaken Mallards for Pintails.
Whilst with us, the Pintail is found in company with the Baldpate or American Widgeon, the Blue-winged Teal, and the Mallard, more frequently on ponds than on streams, although it sometimes resorts to the latter, when their shores are overhung with beech-trees loaded with their nutritious fruits, of which this species is extremely fond, and in search of which they even ramble to a short distance into the woods. Were this Duck to feed entirely on beech-nuts, I have no doubt that its flesh would be excellent. It feeds on tadpoles in spring, and leeches in autumn, while, during winter, a dead mouse, should it come in its way, is swallowed with as much avidity as by a Mallard. To these articles of food it adds insects of all kinds, and, in fact, it is by no means an inexpert fly-catcher.
The Pintails are less shy in the Western Country than most species of their family, and in this respect they resemble the Blue-winged Teals, which in fact might be called stupid birds with as much propriety as many others. They swim rather deeply, keep close together, and raise the hind part of the body like the Mallards; and on the water, on land, or on the wing, several may generally be killed at a shot. A friend of mine killed nineteen with two shots of his double-barrelled gun. They are scarcely nocturnal, but rest much in the middle of the day, basking in the sunshine whilst on the water, whenever they can indulge in this luxury. While on ponds, they feed along the most shallow parts, or by the edges; and if you take my advice, you will never shoot at them while their heads are at the bottom, and their feet kicking above water. I have several times, for diversion, done so, but in no instance did I damage a single individual. But when they raise their heads, you may commit great havoc among them.
During heavy rains in winter, or after them, the Pintails are fond of alighting on our broad prairies, corn-fields and meadows; and in almost every puddle you may then find them busily engaged. They move over the ground as swiftly as Wood Ducks, still carrying their tail erect, unless when seizing an insect that is on wing or resting on a blade of grass. I knew a particular spot in a corn-field, not many miles from Bayou Sara in Louisiana, where, even after a shower, I was sure to meet with this species, and where I could always have procured a good number, had I thought them likely to be prized at the dinner-table. While I was at General HERNANDEZ'S in Florida, the Pintails were very numerous. They alighted everywhere, and I shot a few in order to satisfy myself that they were of the same species as those I had been accustomed to see. On one occasion I shot at a large flock swimming on a shallow pond in a large savannah, and wounded several, which I was surprised to see diving very expertly as I waded out for them, this species being by no means addicted to that practice. Those which I have now and then wounded, while in a boat and in deep water, soon gave up divine, and surrendered, without exhibiting any of those feats of cunning performed by other species.
The flight of the Pintails is very rapid, greatly protracted, and almost noiseless. They arrive in the Western Country mostly in the dusk of evening, and alight without much circumspection wherever they find water. They remain at night in the ponds where they feed, and continue there generally unless much disturbed. On such occasions they keep in the middle of the water, to avoid their land enemies; but the Virginian and Barred Owls not unfrequently surprise them, and force them to rise or make towards the shore, when they fall a prey to the nocturnal marauders. In the Middle States, they are highly esteemed for the table. There they arrive later and retire sooner towards their breeding-places, than in the country west of the Alleghany Mountains.
