The Australian Teal is closely similar to the Teal of Europe. It is a grass feeder, and is a good table bird. The female is very different from the male. It is impossible to distinguish the male Gray Teal from the female Teal when in the free state. Mr. Keartland (ex-President of the Field Naturalist Club, and ornithologist to the Horn and Calvert exploring expeditions) has shown that there is a big difference in weight. The male of the smaller Gray Teal is not brightly colored like the male Chestnut-breasted Teal.

The remarkable Shoveller comes next. It is closely similar to the English Shoveller. Strange that this name was first used for the Spoonbill. The Shovellers are found the world over. The males are very brightly colored in the nesting season.

Unlike most other birds, Swans and Ducks lose the whole of their wing feathers at once when moulting, so that for a short time they cannot fly. As a protection, the gaudy ones acquire a quiet, inconspicuous coloration for a time, so that the male is said to get an "eclipse plumage." Many other birds get a bright dress for the breeding season only, but the male Duck wears his bright dress for the whole year, except in the moulting period. It is then "eclipsed," with the corresponding advantage that he is protected from his many enemies at a time when he is most helpless.

The remarkable Pink-eared Duck has no close relative. It has a small pink spot between the eye and ear, and so is called pink-eyed or pink-eared. It is found only in Australia. The female is similar in color to the male. The name Wigeon, or Widgeon, sometimes applied to this Duck, properly belongs to another of the fresh-water Ducks which is not found in Australia. Hence, this name should not be used for our bird.

Another peculiar Australian Duck is the Freckled Duck. It is a very rare bird. One taken on the ornithologists' excursion to Eyre Peninsula was considered a prize. So far as is known, it does not change color with the season, nor has the male or female the usual bright metallic patch seen on the wing of a Duck.

The "Salt-water Ducks" form the next sub-family. These Ducks, though, are not always true to name, for they are not confined to the salt water. The Victorian representative is the well-known White-eyed Duck, or Hardhead. This Duck was common on the Botanic Gardens Lake, Melbourne, until it was emptied some time ago. Thus, our one "Salt-water Duck" was often seen on fresh water. In the same sub-family come the Eider-Ducks of Iceland and the Logger-head, Racehorse, or Steamer Duck, of Magellan Straits, which is said to lose the power of flight on reaching maturity after the first moult. Thus the life-history tells us that this bird is a degenerate form, and not a primitive flightless form, for it has evidently descended from flying ancestors. It uses its wings to row itself along at great speed.

The ninth sub-family of this group of swimming birds contains two native Ducks. The Blue-billed Duck, the first of these, is "especially adapted for immersion and for obtaining its food from the bottom of the water rather than on its surface." It was thought by Gould to be confined to the coastal lagoons of Western Australia, but it has since been recorded from inland in Victoria, and four specimens have been taken in Tasmania. It remains under the water for a considerable time, and, if hunted, flaps along the surface with its short wings, but hesitates to exercise its "feeble grebe-like flight."

Some writers declare that the large Musk Duck is the most remarkable of the many remarkable birds of Australia. It is the only known species of the genus, and is "singularly different from every other member of the Duck family," as Gould points out. Gould further says that "this extraordinary bird reminds one of the Cormorants. Like many other of these antipodean forms, it must be regarded as an anomaly." The male has a lengthened, stiff, and leather-like appendage under the bill. The female is without this pouch, and is but half the size of the male. A pair is often to be seen on a sheltered bay or on an inland dam, and yet this bird has very feeble powers of flight. It is difficult to cause one to take to flight. Mr. A. J. Campbell summed up an instructive discussion on this point in the columns of The Australasian by concluding that Musk Ducks can fly, though they do so almost entirely at night.
