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 …

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 …

Ducks, Geese, and Swans of the World by Paul A. Johnsgard
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, …

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 …

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 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 following index is limited to the species of Anatidae; species of other bird families are not indexed, nor are subspecies included. However, vernacular names applied to certain subspecies that sometimes are considered full species are included, as are some generic names that are not utilized in this book but which are still sometimes applied to particular species or species groups. Complete indexing is limited to the entries that correspond to the vernacular names utilized in this book; in these cases the primary species account is indicated in italics. Other vernacular or scientific names are indexed to the section of …

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 …
How Birds Combat Ectoparasites, Dale H. Clayton, Jennifer A. H. Koop, Christopher W. Harbison, Brett R. Moyer, Sarah E. Bush
How Birds Combat Ectoparasites, Dale H. Clayton, Jennifer A. H. Koop, Christopher W. Harbison, Brett R. Moyer, Sarah E. Bush
Harold W. Manter Laboratory: Library Materials
Birds are plagued by an impressive diversity of ectoparasites, ranging from feather-feeding lice, to feather-degrading bacteria. Many of these ectoparasites have severe negative effects on host fitness. It is therefore not surprising that selection on birds has favored a variety of possible adaptations for dealing with ectoparasites. The functional significance of some of these defenses has been well documented. Others have barely been studied, much less tested rigorously. In this article we review the evidence--or lack thereof--for many of the purported mechanisms birds have for dealing with ectoparasites. We concentrate on features of the plumage and its components, as well …

Socially Induced Synchronization Of Every-Other-Day Egg Laying In A Seabird Colony, Shandelle M. Henson, James L. Hayward, J. M. Cushing, Joseph C. Galusha

Spontaneous oscillator synchrony has been documented in a wide variety of electrical, mechanical, chemical, and biological systems, including the menstrual cycles of women and estrous cycles of Norway Rats (Rattus norvegicus). In temperate regions, many colonial birds breed seasonally in a time window set by photoperiod; some studies have suggested that heightened social stimulation in denser colonies can lead to a tightened annual reproductive pulse. It has been unknown, however, whether the analog of menstrual synchrony occurs in birdsthat is, whether avian ovulation cycles can synchronize on a daily timescale within the annual breeding pulse. We report every-other-day clutch-initiation and …
