389 AMERICAN WIDGEON
|This lively and very handsome Duck is abundant during winter at New
Orleans, where it is much esteemed on account of the juiciness of its
flesh, and is best known by the name of Zinzin. In the Western Country,
and in most parts of the Eastern and Middle States, it is called the
Bald Pate. Early in September it enters the United States by their
northern extremities, as well as from Texas; and in both these regions
it is now well known to breed in nearly equal numbers. Those which
retreat south-westward remain along the coast and in the interior of the
Floridas, as well as all that portion of the Gulf of Mexico extending to
the mouths of the Mississippi, where they remain until the latter part
of April, sometimes even until the middle of May, as they have but a
comparatively short journey to perform in order to arrive in Mexico in
time to breed. On the coast of the Atlantic they keep in the marshes in
company with various species of the same family, being in a manner
indifferent as to their associates. During early spring, in Louisiana,
they are often seen alighted on extensive plains that have very little
water on them.
While advancing along the shores of the Gulf of Mexico, in April 1837, I and my party observed this species in considerable numbers; and during the whole of our stay in Texas, we daily saw and very frequently procured Widgeons. There they were found in ponds of brackish water, as well as in the fresh-water streams. Before we left that country they were all paired, and I was informed by the Honourable M. FISHER, Secretary to the Texian Navy, that a good number of them breed in the maritime districts, along, with several other Ducks, and that he annually received many of the young birds. Their manners at this time frilly proved the correctness of the statements of all those who spoke to me on this subject. Indeed my opinion is that some of these birds also propagate in certain portions of the most southern districts of the Floridas, and in the Island of Cuba, as I have seen Widgeons in the peninsula in single pairs, in the beginning of May.
Their retrograde movements in spring, like those of other species, depend much upon the temperature or the advance of the season; and those which proceed northward set out on their journey much earlier than those which move in the opposite direction, the former departing from the middle of March to the 20th of April. Their first appearance on the waters of the Ohio takes place late in September or early in October, when they at once throw themselves into the ponds of the interior, and there remain until the waters are closed by ice, scarcely any betaking themselves to the rivers, unless to repose on the sand-bars. They are there, however, less abundant than nearer the sea-coast, and usually associate with Pintails and Teals, but rarely with Mallards or Dusky Ducks. Whilst in those retired ponds of the forest, from one to another of which they roam in quest of food, they are less noisy than most other species, even than the Pintails, and in this respect resemble the Blue-winged Teals, whose notes are feeble and delicate. Those of the Widgeon are a soft whistle, somewhat similar to the word sweet, enunciated as if produced by a flute or a hautboy, and in my judgment not at all like the hew hew spoken of by WILSON. They are less shy in those retired places than most species, or are to appearance less aware of the danger of allowing the sportsman to approach them.
In feeding they immerse their neck and the anterior part of the body, generally swimming closer together than other Ducks, in consequence of which habits they are easily neared and often shot in great numbers at a single discharge. During their stay in those districts they feed on the roots and seeds of grasses, water-insects, beech-nuts, small fry, and leeches, and are not so delicate as an article of food as those procured in the rice-fields of South Carolina, or in the plantations of Louisiana and Florida. On their return in spring (for in mild winters they remain all the season in Kentucky), they generally continue until the end of April, and usually pair before they depart; which induces me to believe that numbers of them breed within the northern limits of the United States, although I have not heard of any having actually been seen doing so.
On the lakes near New Orleans, as well as on the Chesapeake, they are not unfrequently found in company with the Canvass-back Ducks. WILSON mentions their being partially supplied with food by the industry of the latter; but they manage very well in most parts without such assistance. When in full security, the Bald-pates feed at all hours of the day; but in thickly inhabited parts of the country, they usually seek for food at night or early in the morning.
The flight of this species is rather swift, well sustained, and accompanied by the whistling sound of the wings usual in birds of this family. They move in flocks of moderate size, and without much care as to the disposition of their ranks, being sometimes extended into a front line, sometimes in single file, frequently mingled confusedly, and flying at a moderate height, whether over the land or over the water. When they are first started, they fly almost perpendicularly, in a hurried and rather irregular manner. They walk prettily and with ease. After heavy falls of rain in our Southern States, they often alight in the corn-fields, in company with other Ducks, where the ploughed earth, being quite moist and soft, yields them an abundant supply of worms and insects, as well as grains of corn, peas, and other equally nutritious substances.
Dr. RICHARDSON informs us that this species breeds in the woody districts of the Fur Countries, up to their most northern limits, in latitude 80 degrees; and Mr. TOWNSEND states that it is abundant on the Columbia river; but he has not furnished me with any account of its breeding, and I have not had an opportunity of observing it during the season of propagation, as I left Texas without having found a nest or young.

A very great diversity of colouring exists in this species, which, however, is not yet properly understood. Although males are often found as described above, and as represented in the plate, others have a very different appearance. Thus, an individual shot at the mouth of the Mississippi, in the beginning of April 1837, has the head and neck brownish-orange, the feathers all minutely tipped with dark green, the lower fore neck lilac; all the upper parts finely undulated with white and dusky, as are the sides; the wing-coverts light brownish-grey; the other parts as described above, but the upper tail-coverts black at the end. In some individuals the top of the head is reddish-white, in others light red, in others pure white; in some, most of the smaller wing-coverts are white, in others grey or brownish-grey; in some the throat is whitish, in others black. These differences, no doubt, depend upon age and season.
The American Widgeon has been considered distinct from the European; not on account of any difference in size or form, or texture of plumage, but because it has in certain stages a green band on the side of the head, which the European bird is said not to have. The mirror is the same in both; the wing-coverts are white or grey in both; the crown is white, or cream-coloured, or orange-brown, in both; but in the European the head and neck are described as reddish-chestnut, and in the American as yellowish-white. Now, in fact, American birds sometimes have the head and neck red, and European birds sometimes have the green streak on the side of the head. In short, on comparing specimens from America, with others from India and Norway, I cannot perceive any essential difference. At the same time, not having traced our Widgeon through all its gradations, and being equally unacquainted with all those of the European and Asiatic Widgeon, I cannot positively affirm that Anas Americana is identical with Anas Penelope.
A male preserved in spirits presents the following characters.
The roof of the mouth is deeply concave, with a median prominent line, and numerous irregular small tubercles on the sides, with several larger ones at the fore part. Two large branches of the supra-maxillary nerve run in this ridge, as in other Ducks. The tongue is 1 inch 5 twelfths long, with numerous straight, pointed papillae at the base, a median longitudinal groove, and a thin broadly rounded point. The oesophagus, Fig. 1 [a b c d], is 10 inches long, narrow, dilating a little on the lower part of the neck, where its diameter is 1/2 inch. The proventriculus, [b c], is 8 twelfths broad; its glands oblong, 2 twelfths in length, and occupying a belt 1 inch 4 twelfths in breadth. The gizzard, [e f g], is extremely large, of a nearly regular elliptical form, placed obliquely, its length 1 inch 8 twelfths, its breadth 2 1/2 inches; its lateral muscles extremely large, the left, [e], 1 inch 2 twelfths in thickness, the other, [f], 1 inch and 1 twelfth; the inferior muscle, [g], only 1 twelfth. In the oesophagus are contained slender leaves of grasses; in the gizzard some of these leaves and other vegetable matters, small seeds, and a great quantity of sand. The cuticular lining or epithelium is dense, slightly rugous, much thickened on the spaces opposite the middle of the lateral muscles. The duodenum, [g h i], is 5 1/2 inches in its first curve, [g h], and is then reflected for 7 inches, passes backwards under the kidneys and forms several convolutions. The intestine, [g h i j k l], is 6 feet 2 inches long, 1/2 inch in diameter in its duodenal portion, gradually contracts to 4 twelfths at the distance of 18 inches from the pylorus, again enlarges to 5 twelfths, and near the rectum to 7 twelfths. The rectum is 4 1/2 inches long; the coeca 9 inches, their diameter for nearly 2 inches being 2 twelfths, after which they are enlarged, their greatest diameter being 4 twelfths. The liver is large, the right lobe being 3 1/2 inches long, the left 2 1/2.
The trachea, [m], is 7 1/2 inches long, of moderate diameter, the rings roundish and ossified, about 140 in number, its breadth at the top 4 1/2 twelfths, gradually diminishing to 3 twelfths. At the lower part several of the rings are united so as to form an irregular dilatation, bulging out into a rounded sac, [n], on the left side, its greatest diameter being 10 twelfths. The bronchi are of moderate length, wide, with about 25 half rings. The contractor muscles are rather strong; and besides the sterno-tracheals, [o p], there is a pair of cleido-tracheals.
In a female, the gizzard is 2 inches in its greatest diameter; the intestine is 5 feet 2 inches long. The contents of the oesophagus and stomach as in the male.
