Impacts of non-renewable resource extraction on shrubland songbird nest success and abundance
… Land management practices which produce early-successional habitat, namely field abandonment and clearcut timber harvests, have become increasingly uncommon in the eastern United States, and natural maintenance processes such as fires and floods are often suppressed. The Appalachian region is …

The Role of Urban Climate and Land Cover in Phenology, Nest Success, and Habitat Use
… temperature variation and urban land cover for nest survival, the function of thermal refuges for habitat use by breeding birds, and the relationship between urban climate and phenology. Temperatures, leaf phenology, invertebrate abundance, nest habitat, and nest fate were monitored over a …

Habitat use, nest success, and management recommendations for grassland birds of the Canaan Valley National Wildlife Refuge, West Virginia
… the eastern United States may provide adequate nesting habitat for grassland species displaced from their native habitat. The objectives of this study were to: (1) compare grassland bird abundance, diversity, and richness of species between 3 idle hayfields and 3 pastures and between mowed and …

Northern pintail nest site selection, nest success, renesting ecology and survival in the intensively farmed prairies of southern Saskatchewan: an evaluation of the ecological trap hypothesis
Unlike most prairie nesting ducks (Anas spp.), the North American population of northern pintails (A. acuta, hereafter pintails) has failed to respond as expected to improved wetland conditions on the U.S. and Canadian prairies during the mid to late 1990s. My primary objectives were to test the …

Evaluation of Mixed-Vegetation Plantings As Avian Nesting Habitat in Eastern South Dakota
… grasses have long been planted as avian nesting cover on wildlife management units. However in the recent past, there has been a trend toward planting native warm-season grasses. In 2000, South Dakota Game, Fish and Parks (SDGFP) began planting mixtures of cool-season and warm-season …

INDIRECT EFFECTS OF LOW AMPLITUDE ARVICOLINE CYCLES ON DAILY NEST SURVIVAL OF DUNLIN (CALIDRIS ALPINA HUDSONIA) IN A RAPIDLY CHANGING CLIMATE
… risk on alternative prey such as shorebird nests as they share predators. I examined the indirect effects of arvicoline rodent cycles on Dunlin (Calidris alpina hudsonia) reproduction in Churchill, Manitoba. Using 10 years of field data, the study suggests collared lemming (Dicrostonyx …

Behavior, Nest Site Selection and Success of Black Terns (Chlidonias niger)
… of which are still largely unknown. I monitored nest success and wetland use by Black Terns in three colony sites in northern Michigan throughout 2017 and 2018 and used traditional survey methods coupled with nest cameras to document Black Tern nest success and mortality events. Colony sites …

Avian population and community dynamics in response to vegetation restoration on reclaimed mine lands in southwest Virginia
… mining, there may be potential to create early successional habitat needed by many avian species currently in decline throughout eastern North America. I evaluated nest-site selection and nest success for on reclaimed mine lands in southwest Virginia during the summers of 2010 and 2011. For this …

Pheasant Nesting and Vegetation Development in Dense Nesting Cover Established Under the South Dakota Pheasant Restoration Program
Pheasant (Phasianus colchicus) nest use of dense nesting cover (DNC) established under the Pheasant Restoration Program was evaluated in Beadle, Codington, Tripp, and Walworth Counties in South Dakota from 1978 to 1981. Nest densities and success in DNC plots were compared to those found in …

Effects of black flies on wild turkey reproductive success
Reproductive success is an important driver of population dynamics in wild avian populations. Establishing what factors influence reproductive success is necessary for informing management strategies that ultimately aid in sustaining populations. For game species (i.e., those that are hunted) …

MALLARD NESTING ECOLOGY IN THE GREAT LAKES
… growth (i.e., λ) is most sensitive to changes in nest success (16%) and duckling survival (32%). In spring of 2001 to 2003, as part of the Great Lakes Mallard Study, 536 mallards were radio-marked at nine sites in four states (Michigan, Ohio, Wisconsin, and Indiana). I tested a set of a priori …

Influence of Predation on Least Tern and Piping Plover Productivity Along the Missouri River in South Dakota
… on the survival of piping plover and least tern nests and chicks in this region. American crows, raccoons and mink were associated with 98. 0% of the known nest losses. American kestrel and great horned owl predation accounted for 93. 0% of the chick mortality. The effects of predation were found …

Productivity of A Resident Giant Canada Goose Flock in Northeastern South Dakota
… reported. Twenty-four percent of the artificial nest structures (ANS) available were used by nesting geese. Artificial nesting structures, islands, muskrat houses and peninsulas were used by geese as nesting sites. Mean clutch size of completed nests was 5.14 in 1974 and 5.26 in 1975. Mean clutch …

Nesting and Brood-Rearing Success and Resource Selection of Greater Sage-Grouse in Northwestern South Dakota
… We conducted a 2-year study to investigate the nesting and brood-rearing ecology of sage-grouse in northwestern South Dakota. Female sage-grouse were captured and radio-marked (n = 53) on traditional display grounds. Radio-marked hens were tracked to estimate nesting effort, nest success, and …

Parasite-host interactions in an arctic goose colony
… Parasites influence the reproductive success of their hosts in some cases. Studies on impacts of ectoparasites on avian reproductive success have generally been focused on species with altricial young. I studied the abundance of an apparently newly emerging nest-parasite and the …

Avian Nesting Density and Success in Alfalfa, Cool Season CRP, and Warm Season CRP Planting in Eastern South Dakota
… fields are notorious for attracting grassland nesting birds only to have their nests destroyed by mowing operations. Few studies have been done comparing nest success and densities in Conservation Reserve Program fields (CRP) and alfalfa in South Dakota. Objectives of the study were to: (1) …
