Woodpecker Nesting Habitat in a Prairie River Woodland
<p>Differences in nest site selection of the common flicker (Colaptes auratus), yellow-bellied sapsucker (Sphyrapicus varius), downy woodpecker (Picoides pubescens), and red-headed woodpecker (Melanerpes erythrocephalus) were studied on the Big Sioux River riparian forest of eastern South Dakota …

Characteristics of the nesting habitat of the black-throated blue warbler
… were combinations of either macro or microhabitat subsets of vegetational variables. In the nest site analysis, four macrohabitat factors described the presence of major tree species, along with structural characteristics of the overstory and understory. The interaction of overstory and …

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 …

Wetlands Area and Embankment Design for Stimulating Duck Nesting Habitat and Success in Sioux County, North Dakota
… embankment is to develop wetlands areas for duck habitat and nesting in south-central North Dakota. The embankment will be constructed from compacted soils taken from two locations that are within a half mile from the proposed embankment location to create a lower transport cost. The embankment …

Assessing the Effects of Sea-Level Rise on Piping Plover (Charadrius Melodus) Nesting Habitat, and the Ecology of a Key Mammalian Shorebird Predator, on Assateague Island
… U.S. Atlantic Coast and is highly vulnerable to habitat change and predation. We have addressed these two threats by 1) developing and implementing a linked model system that predicts future change to piping plover habitat resulting from sea-level rise and beach management efforts by joining …

Re-Establishing Bald Eagle and Osprey Breeding Populations in South Dakota Through Hacking: A Feasibility Study
… to the large scale of the study, variation in habitat types, and the amount of information available for each habitat assessed. Hacking feasibility and whether or not a hacking program was warranted were determined by (1) assessing the nesting suitability of river, lake, and reservoir habitats …

A Study of Habitat Variables Associated with Northern Goshawk Nest Site Activity on the Three National Forests in Southern Utah
… part to loss of critical breeding and wintering habitat. Nest site selection of goshawks has been correlated with certain specific site characteristics including, but not limited to, forest species composition, forest stand size, diameter of nest tree, percent cover, tree height, site slope, and …

Factors affecting piping plover (Charadrius melodus) nest site selection following landscape and predator community changes
… and human interventions significantly impact nesting habitat use by species like the piping plover (Charadrius melodus) along Atlantic coastlines. Our study focused on Fire Island, New York, assessing changes in vegetation succession, plover nesting habitat selection, and suitable nesting …

Nesting Giant Canada Geese in Western South Dakota
… Canada geese (Branta Canadensis maxima) began nesting on 27 March 1976 and 2 April 1977. Peak hatch occurred from 15 to 21 May 1976 and 22 to 28 May 1977 and the nesting season lasted 69 days in 1976 and 83 days in 1977. Average clutch size was 4.8 eggs per nest in 1976 and 5.0 in 1977. …

Land Use Changes and Pheasant Declines in Eastern South Dakota
Changes in pheasant (Phasianus colchicus) nesting habitat were investigated on Windsor Township, Brookings County, South Dakota. The population was censused, nesting densities determined, cover was mapped, and an interspersion index determined in 197 7 and 1978. Comparison to a similar study …

The ecology of translocated greater sage-grouse in Strawberry Valley, Utah
… were within current and historic sage-grouse habitat in Strawberry Valley, and we detected no grouse outside of the study area. Nesting propensity for first (newly translocated) and second (surviving) year females was 39% and 73%, respectively. Observed nest success of all translocated females …

Population Dynamics of Threatened Piping Plovers on the Niobrara River, Nebraska
… of the Great Plains, USA, provide important habitat for the federally threatened piping plover (“plover”, Charadrius melodus). Plovers nest on open to sparsely vegetated river sandbars, and their demographic rates are closely linked to habitat availability and quality, as well as river flow. …

Reproductive Ecology of Ring-Necked Pheasants in Central South Dakota's Winter Wheat Landscape
… it is possible winter wheat may be an alternate nesting habitat for pheasants. Winter wheat is predominately undisturbed throughout the pheasant’s nesting season, and undisturbed habitat provides an effective environment for nesting hens to avoid predators. The objectives of this study were to …

Factors limiting piping plover nesting pair density and reproductive output on Long Island, New York
Storm-created nesting habitat and low wave energy moist sediment habitat (MOSH), such as intertidal sandflats, have long been considered important to the recovery of the piping plover (Charadrius melodus), a federally threatened shorebird. Beach renourishment is a common practice on the U.S. …

From nesting to emergence: Environmental drivers of hatchling success in Blanding’s turtles and implications for management in Southeast Michigan
… emergence success and hatchling condition. Nesting females were morphologically similar in size and produced average clutch sizes for the species (8 ± 2 eggs). Nest sites were found on relatively open, disturbed uplands with sandier soil substrates. Emergence success was generally high (≈ …

The Effects of Wildfire Burn Severity on Bee and Wasp Communities Two Decades Post-Fire
… the effects of wildfire burn severity on cavity-nesting bee and wasp abundance and diversity, and nesting habitat across burn severities (high, low, unburned) in the same mixed-severity fires. We found that fire severity had no impact on cavity-nesters, but that high severity fire did increase …
