Available in PDF, EPUB and Kindle. Book excerpt: "Emperor Geese (Chen canagica) breed on the Yukon-Kuskokwim Delta in an area inhabited by three other goose species. Whereas populations of other geese increased since the mid 1980s, Emperor Goose numbers remained low. Because survival and habitat selection by broods of Emeperor Geese had not been studied previously and numbers of predatory Glaucous Gulls (Larus hyperboreus) had recently increased, I studied brood rearing ecology of Emperor Geese during 1993-1996 to assess whether this seasonal period could be limiting population growth. Survival of goslings to 30 days varied among years from 0.32 to 0.70 and was primarily influenced by mortality during the first five days after hatch. Other goose species with similar rates of gosling survival are increasing rapidly. Survival of Emperor Goose goslings was lowest in 1994, when unusually heavy rainfall occurred during early brood rearing. Using a long-term data set from Izembek National Wildlife Refuge, sizes of families in fall (n=23 years) were related to rainfall during early brood rearing. Gosling survival was lower and gull disturbance of broods greater in 1993-1994 than in 1995-1996. Although goslings wer commonly consumed by Glaucous Gulls, gull diets during 1993 were similar to those observed in the 1970s. Across a broad scale, broods of Emperor Geese (n=56) strongly selected habitats dominated by Carex subspathaceae, Carex ramenskii, and unvegetated areas interspersed among these forage species, as determined from telemetry. These selected habitats comprised one-third of all available habitat. Habitat selection by the composite goose community (dominated by Cackling Canada Geese [Branta canadensis minima]) was assessed by feces collections and differed substantially from that of Emperor Geese. Broods of Emperor Geese spent more time feeding during 1993-1996 than during an earlier study in 1985-1986. During 1994-1996, feeding rates of gosling and adult females was related more to total goose density than to Emperor Goose density. Although Cackling Canada Geese exhibited strongest selection of other habitats, their greater overall abundance resulted in numerical equivalence to Emperor Geese in habitats preferred by Emperor Geese. Interspecific competition for food has impacted behavior in Emperor Geese, which may impact growth and survival of juvenile geese"--Leaves 3-4

Available in PDF, EPUB and Kindle. Book excerpt: Ducks, Geese, and Swans of North America has been hailed as a classic since the first edition was published in 1942. A must-have for professional biologists, birders, waterfowl hunters, decoy collectors, and wildlife managers, this fully revised and updated edition provides definitive information on the continent's forty-six species. Maps of both winter and breeding ranges are presented with images by top waterfowl photographers and the acclaimed original artwork of Robert W. (Bob) Hines. Originally authored by F. H. Kortright and later revised by Frank Bellrose, this latest edition, which has been meticulously updated by renowned waterfowl biologist Guy Baldassarre, continues the legacy of esteemed authors. Each species account contains in-depth sections on: - identification - distribution - migration behavior - habitat - population status - breeding biology - rearing of young - recruitment and survival - food habits and feeding ecology - molts and plumages - conservation and management To facilitate identification, the species accounts also include detailed illustrations of wings. An appendix contains comparative illustrations of ducklings, goslings, and cygnets. Guy Baldassarre has hit the target. His remake of the Kortright/Bellrose classic provides good biological descriptions, wonderful photographs and illustrations, and easy-to-understand information about waterfowl. I would encourage every hunter and enthusiast to have these books as an educational guide to waterfowl and their needs.--H. Dale Hall, CEO, Ducks Unlimited, Inc. When, as an eleven-year-old in 1942, I read F. H. Kortright's first edition of this book, it altered the trajectory of my life. Every subsequent edition, including this latest update by Guy Baldassarre, has improved the landmark reference. I can't imagine that anyone interested in waterfowl or wetlands can live without this indispensable book.--Paul A. Johnsgard, University of Nebraska-Lincoln Creating a brand-new version of such a timeless and previously revised classic is a risky venture indeed, but nobody could be better suited for this monumental task than Guy Baldassarre. He has created a stunning new classic, at once magnificent in its visual appeal and truly comprehensive in its scientific breadth and depth. Hats off to Guy for dedicating himself to this project with such obvious passion, patience, and skill. This book absolutely belongs on the shelf or coffee table of anyone who has ever marveled at waterfowl, whether through their binoculars or from inside the duck blind.--John W. Fitzpatrick, Cornell Laboratory of Ornithology Guy Baldassarre was a professor of wildlife ecology at the State University of New York College of Environmental Science and Forestry in Syracuse until his death in 2012. He is the coauthor of the textbook, Waterfowl Ecology and Management.

Available in PDF, EPUB and Kindle. Book excerpt: The Barnacle Goose, a distinctive, handsome black-and-white bird, gets its name from a mediaeval myth that the birds hatched from barnacles – how else to explain their sudden appearance each autumn in northern Britain? We now know, of course, that the birds migrate from Arctic Russia, Norway and Svalbard to winter throughout northern Europe. This book represents a culmination of more than 25 years of Barnacle Goose research. It represents the story of one of Europe's most celebrated long-term behavioral studies, detailing the lives of these social and sociable birds. Chapters include sections on pair formation and bonding, family and population dynamics, brood parasitism, food and feeding, size and shape in different populations, life cycle, survivorship, dispersal, migration, and conservation, with particular regard to climate change. It is a rigorous and thorough examination of the lives of these birds, in fine Poyser tradition.

Available in PDF, EPUB and Kindle. Book excerpt: "Body size is an important determinant of life history traits such as survival and fecundity. There is a positive correlation between growth during the first summer and final body size in goose populations. I examined how environmental factors influence growth in Black Brant (Branta bernicla; hereafter brant) goslings. Growth declined seasonally and varied among brood-rearing areas. However, the pattern was not consistent among years. Models containing only environment and maternal effects explained 75% of variation in gosling mass, indicating that little of the observed variation in size is directly of genetic origin. Heritability did not differ from zero for both mother-daughter and father-daughter regressions. I also conducted an experiment to study the effect of gosling density on food abundance, feeding behavior, and development of brant goslings, in two habitat types important to brant: (1) Carex subspathacea grazing lawns and (2) slough levees which contain Triglochin palustris. Variation in grazing pressure was experimentally manipulated. Biomass and offtake of C. subspathacea was higher in lightly grazed plots than in heavily grazed plots even though goslings within heavily grazed plots spent more time feeding. Within slough levee habitat there were no differences between heavily and lightly grazed plots in either biomass or offtake of T. palustris. Peck rates were lower in slough levee habitat than in grazing lawns. Change in mass over an eight hour trial was positively correlated with the amount of forage biomass in the plot at the start of the trial. I found no variation in internal morphometrics or body composition among goslings. I also examined the relationship between forage available within a brood-rearing area, the number of birds using the area, and gosling growth. Annual variation in use of brood-rearing areas was correlated with forage availability. Gosling mass was negatively correlated with brood numbers when examined across all areas, however, within each brood-rearing area, the relationship between mass and numbers of birds was positive. I did not see a relationship between estimates of food availability (per m2) and brood numbers. Spatial variation in growth among habitats may result from habitats varying in quality and quantity of forage"--Leaf 4
