Wetlands conserved using water level manipulation, cattle exclusion, naturalization of uplands, and other techniques under the North American Waterfowl Management Plan (“conservation project wetlands”) are important for ducks, geese, and swans (

Understanding habitat associations of breeding mallards (Anas platyrhynchos) and Canada geese (Branta canadensis maxima) in the eastern US and Canada is important for conservation planning, yet studies at spatial scales useful to conservation planner

Given historical patterns of decline, the American Black Duck (Anas rubripes) has long been a species of concern. To support the identification of core Maritime habitat, the distribution of breeding ducks was mapped at the landscape scale through the

Several hypotheses have been proposed to explain the evolution of conspecific brood parasitism (CBP), and recent studies suggest that nest predation may be an important factor in shaping this behavior. We assessed whether individuals that engage in p

We compared foraging times of female Ross's (Chen rossii) and Lesser Snow Geese (Chen caerulescens caerulescens) breeding at Karrak Lake, NT, Canada and examined variation due to time of day and reproductive stage. We subsequently collected female ge

We investigated the use of stable-isotope analysis as a direct means of tracing allocation of endogenous protein and lipid reserves to reproduction in five gulls (Larus canus, L. delawarensis, L. californicus, L. argentatus, L. philadelphia), four te

Recent research suggests that foods eaten during laying and incubation play a greater role in supplying energy and nutrients to arctic-nesting geese than previously be- lieved. We conducted food-supplementation experiments with Ross's Geese (Chen ros

Body size can impose tighter energetic constraints on smaller than on larger species. Accordingly, we tested whether smaller duck species were more inclined than larger species to save on metabolic costs by using nest sites that received more solar r
