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 ...

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 ...

Black-headed Duck
Masked Duck
Ruddy Duck
White-headed Duck
Maccoa Duck
Argentine Blue-billed Duck
Australian Blue-billed Duck
Musk Duck

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 ...

This tribe of primarily fresh-water diving ducks contains 16 species that collectively may be called pochards. The tribe has a nearly worldwide distribution, but only a few of its species have ranges that extend beyond a single continent. In addition to 15 species that are very similar in body proportions and diving adaptations, the apparently extinct pink-headed duck has anatomical characteristics that approach those of the pochards and ...

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 ...

Exon-Primed Intron-Crossing (Epic) Markers For Non-Model Teleost Fishes, Chenhong Li, Jean-Jack M. Riethoven, Lingbo Ma 2010 University of Nebraska - Lincoln

Exon-Primed Intron-Crossing (Epic) Markers For Non-Model Teleost Fishes, Chenhong Li, Jean-Jack M. Riethoven, Lingbo Ma

Papers in Evolution

Background: Exon-primed intron-crossing (EPIC) markers have three advantages over anonymous genomic sequences in studying evolution of natural populations. First, the universal primers designed in exon regions can be applied across a broad taxonomic range. Second, the homology of EPIC-amplified sequences can be easily determined by comparing either their exon or intron portion depending on the genetic distance between the taxa. Third, having both the exon and intron fragments could help in examining genetic variation at the intraspecific and interspecific level simultaneously, particularly helpful when studying species complex. However, the paucity of EPIC markers has hindered multilocus studies using nuclear gene ...

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 ...


North America’S Ducks, Geese And Swans In The 21st Century: A 2010 Supplement To Waterfowl Of North America, Paul A. Johnsgard 2010 University of Nebraska-Lincoln

North America’S Ducks, Geese And Swans In The 21st Century: A 2010 Supplement To Waterfowl Of North America, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010)

Since the 1975 publication of Waterfowl of North America, a great deal of ornithological literature has appeared concerning North American ducks, geese & swans. The most significant of these are the species accounts in the American Ornithologists’ Union The Birds of North America (B.O.N.A.) series, 46 of which were published between 1993 and 2003, and which include all the species known to breed in the United States and Canada (see references).

Population data of wild species are constantly changing, and sometimes of limited accuracy, but long-term averages or trends are often significant. National population surveys such as the annual U.S. Fish & Wildlife Service’s Breeding Bird Surveys, and annual hunter-kill (“harvest”) surveys by the U.S. Fish & Wildlife Service and Canadian Wildlife Service are thus of both immediate and long-term interest.

Text updates for the following species accounts are minimal. I have stressed apparent population trends and identified new major literature sources. I have also modified the majority of the range maps to make them more closely conform to our present-day knowledge of breeding and wintering ranges. The breeding ranges of some species are still inadequately known, such as those of the scoters, which breed in large regions of Canada and Alaska that are still only poorly surveyed. Not only have breeding ranges changed or become clearer, but also many wintering ranges have changed markedly since the 1970s, in conjunction with global warming trends (Johnsgard, 2009; Niven, Butcher & Bancroft, 2009).

Waterfowl Of North America: Waterfowl Distributions And Migrations In North America, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010)

The species of waterfowl breeding in North America have distribution patterns that collectively reflect the past geologic and ecological histories of this continent. In general, our waterfowl species may be grouped into those that are limited (endemic) to North America, those that are shared between North and South America, and those that are shared with Europe and/or Asia. Of the forty-four species known to breed in continental North America, the resulting grouping of breeding distributions is as follows:
Limited to North America: Snow goose (also on Greenland and Wrangel Island) , Ross goose, Canada goose (also on Greenland), wood duck ...


Waterfowl Of North America: Identification Key To North American Waterfowl, Paul A. Johnsgard 2010 University of Nebraska-Lincoln

Waterfowl Of North America: Identification Key To North American Waterfowl, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010)

The key on the following pages provides an efficient means of identifying virtually all North American waterfowl that may be examined in the hand. The procedure for using it is comparable to that used for all such dual-choice or "dichotomous" keys. One simply chooses which of the initial descriptive couplets (A or A') best fits the unknown bird. Having chosen one of these, the pair of descriptive couplets (a and a') immediately below the chosen alternative is next considered, without further regard for the rejected one. Subsequent choices, which are sequentially numbered (1 and 1', 2 and 2', etc.) must ...


Waterfowl Of North America: Hunting And Recreational Values Of North American Waterfowl, Paul A. Johnsgard 2010 University of Nebraska-Lincoln

Waterfowl Of North America: Hunting And Recreational Values Of North American Waterfowl, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010)

It is almost as difficult to find individuals opposed to waterfowl conservation as it is to hear Americans speaking out against motherhood or corn on the cob. Yet, in a real sense, it has been the American tradition of unchecked population expansion, taming the wilderness, and converting prairies and marshes into cornfields that has nearly spelled disaster for some of our native waterfowl. Of a wetland area in the United States that originally covered some 127 million acres, nearly 50 million acres have already been drained and lost as waterfowl habitat. Marshes have not only been converted to farmland but ...


Waterfowl Of North America: Swans And True Geese Tribe Anserini, Paul A. Johnsgard 2010 University of Nebraska-Lincoln

Waterfowl Of North America: Swans And True Geese Tribe Anserini, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010)

The approximately twenty extant species of swans and true geese are, unlike the whistling ducks, primarily of temperate and arctic distribution, especially in the Northern Hemisphere. It is thus not surprising that continental North America may lay claim to at least nine breeding species, or nearly half.of the known total. Additionally, sufficient records of a tenth, the barnacle goose, are known as to warrant its inclusion in the book even though there is no indication that it nests in continental North America. Several additional Old World species of geese and swans have been reported one or more times in ...


Waterfowl Of North America: Surface-Feeding Ducks Tribe Anatini, Paul A. Johnsgard 2010 University of Nebraska-Lincoln

Waterfowl Of North America: Surface-Feeding Ducks Tribe Anatini, Paul A. Johnsgard

Waterfowl of North America, Revised Edition (2010)

The surface-feeding, dabbling, or similarly described ducks are a group of about thirty-six species of mostly freshwater ducks that occur throughout the world. Many of them are temperate or arctic-breeding species that nest on dry land near freshwater ponds, marshes, rivers, or similar rather shallow bodies of water. Associated with this breeding habitat are their adaptations for foraging by "tipping-up" rather than by diving for food, an ability to land and take off abruptly from small water areas or land, and a moderately good walking ability but reduced perching capabilities as compared with perching ducks. Also unlike perching ducks, iridescent ...
