Ducks, Geese, And Swans Of The World: Tribe Cereopsini (Cape Barren Goose), Paul A. Johnsgard
Ducks, Geese, And Swans Of The World: Tribe Cereopsini (Cape Barren Goose), Paul A. Johnsgard
Ducks, Geese, and Swans of the World by Paul A. Johnsgard
Cape Barren Goose
Several recent studies have suggested that this unusual Australian gooselike bird is not very closely related to either the true geese or the sheldgeese, although it shares some traits with both groups. It has some unique traits, such as its unusually swollen bill, its adaptations to a terrestrial existence on the coastline and islands of the Bass Strait, and its very simple syringeal structure. Like the freckled duck, it is perhaps best considered as a survivor of a group transitional between the two major subfamilies of waterfowl that exist at the present time.

Torrent Duck
This remarkable stream-dwelling duck of the Andean mountains is certainly one of the most specialized of all waterfowl, and in part its anatomical and behavioral specializations have obscured its basic relationships, which appear to be with either the perching ducks or the dabbling ducks. In the absence of definitive evidence, it seems reasonable to maintain a separate tribe for this species, which exists as a series of relatively isolated populations between Venezuela and Tierra del Fuego that vary greatly in male plumage characteristics. Torrent ducks are essentially cavity- or ledge-nesting forms, although only a few nests have been …

Ducks, Geese, And Swans Of The World: Tribe Stictonettini (Freckled Duck), Paul A. Johnsgard
Ducks, Geese, and Swans of the World by Paul A. Johnsgard
Freckled Duck
Even more than the Cape Barren goose, the freckled duck exhibits an assortment of anatomical traits that suggest affinities with the geese and swans, in spite of a fairly typical ducklike appearance and foraging behavior. Its unpatterned downy young, its remarkably primitive syringeal structure, and its reticulated tarsus all strongly argue for the position that this species is the sole survivor of a very ancient waterfowl lineage, with no near living relatives. A detailed study of its social behavior is greatly to be desired, for like the magpie goose, it provides an unequaled opportunity to gain insight into …

Ducks, Geese, and Swans of the World by Paul A. Johnsgard
Other vernacular names. Semipalmated goose, pied goose, black-and-white goose; Spaltfussgans (German); oie pie (French); gans overo o pintado (Spanish).
This is the only species of true waterfowl with only partially webbed feet. Adults of both sexes are black on the head, neck, wings, rump, and tail, and white elsewhere. The bill is long and straight, with a well-developed nail at the tip; as in swans, the head is featherless back to the eyes. Females resemble males but are somewhat smaller, lack an enlarged bony crown, and have a higher-pitched voice. Adult males have an elongated trachea that loops downward between …

Ducks, Geese, and Swans of the World by Paul A. Johnsgard
Flying Steamer Duck
Magellanic Flightless Steamer Duck
Falkland Flightless Steamer Duck
The South American steamer ducks have at times been included with the shelducks, but differ enough from them in structure and behavior to be regarded as a separate but closely related tribe. There are three species very similar in appearance; two are essentially flightless. All are found off the coasts of southern South America and the Falkland Islands, where they feed on mollusks and other marine invertebrates. The males differ slightly from females in their plumage and vocalizations, but in both sexes iridescent coloration is totally lacking and only …

Black-bellied Whistling Duck
White-backed Duck
The whistling ducks are a group of nine species, eight of which are readily placed in the single genus Dendrocygna, or "tree ducks." However, they are not primarily perching birds, and thus "whistling ducks" is a better vernacular designation than the frequently used "tree ducks." In nearly all species both sexes utter a clear, often multisyllabic whistle that readily identifies the bird as to its species and apparently provides important communication signals …

Ducks, Geese, And Swans Of The World: Contents, Preface, & Introduction, Paul A. Johnsgard
Ducks, Geese, and Swans of the World by Paul A. Johnsgard
Inasmuch as the primary purpose of this book is to provide information on each of the species of the waterfowl family in a standardized format and easily accessible manner, it is important that the reader have some knowledge of the basis for my sequential organization of these species. A variety of attempts to provide a "natural" classification, or one that best reflects actual evolutionary relationships, of the family Anatidae have been made in recent years, with most of them being minor variations on a scheme first proposed by Jean Delacour and Ernst Mayr in 1945. In this landmark classification, emphasis …

This group of 13 species of primarily perching waterfowl is a rather heterogeneous assemblage of birds that are not easily characterized. In addition to being generally perching and cavity-nesting, they also have fairly wide, rounded wings, elongated tails, and sometimes also relatively long legs. Many of the species exhibit a great deal of iridescent coloration in their plumage, even among females, and in a few species nearly …

The most gooselike species of the subfamily Anatinae are the sheldgeese, which together with the closely related shelducks constitute the tribe Tadornini. This group of 14 species has a worldwide distribution except for North America. The typical sheldgeese are grazing birds, the ecological counterparts of the true geese, while the shelducks are mostly wading and dabbling birds, frequently feeding to a large extent on aquatic invertebrates. In all …

The stiff-tailed ducks are characterized by several unusual features in addition to their long, stiffened tail feathers that serve as underwater rudders. Among other adaptations are their very large feet, which are placed so far back on the body that it is difficult for these birds to walk on land. The body feathers are small, numerous, and have a grebe-like sheen, and the wings are so short that takeoff and flight is attained with difficulty. All of the species have relatively short …

The World’S Waterfowl In The 21st Century: A 2010 Supplement To Ducks, Geese, And Swans Of The World, Paul A. Johnsgard
Ducks, Geese, and Swans of the World by Paul A. Johnsgard
Since the 1978 publication of my Ducks, Geese and Swans of the World hundreds if not thousands of publications on the Anatidae have appeared, making a comprehensive literature supplement and text updating impossible. Janet Kear’s (2005) survey of the waterfowl family Anatidae and closely related screamers of the family Anhimidae included more than 3,700 references, of which a significant proportion appeared later than 1978. My revision of the Anseriformes (families Anatidae and Anhimidae) for the 2nd edition of J. C. Peters’ Check-List of the Birds of the World (Johnsgard, 1979) closely followed the classification structure and taxonomic sequence that had …

The only one-volume comprehensive survey of the family Anatidae available in English, this book combines lavish illustration with information on the natural history, distribution and status, and identification of all the species.
After an introductory discussion of the thirteen tribes of Anatidae, separate accounts follow for each of the nearly 150 recognized species. These include scientific and vernacular names (in French, German, and Spanish as well as English), descriptions of the distribution of all recognized subspecies, selected weights and measurements, and identification criteria for both sexes and various age classes. The “Natural History” section of each species account considers habitats, …
