Community Structure, Nesting Success, and Isolation Effects in a Tropical Forest Bird Community
… equally rare in Amazonia. Second, I measured the nesting success of 68 species breeding in the forest understory at Limbo and three nearby sites. Nesting success varied greatly among species, and was significantly different between the two years of the study. In general, nesting success was …

Wood Duck Use and Nesting Success in Artificial Nesting Structures in Eastern South Dakota
… 11 plastic single-walled (PSW), and 154 wooden nesting structures; in 1992, 382 of the boxes were PDW, 13 PSW, and 264 wooden. In both years an additional 10 nest boxes of fiberglass or metal were also monitored. Overall, 206 wood duck nesting attempts occurred, of which 142 were successful. Of …

Nesting Success and Parental Behavior of the Prothonotary Warbler (Protonotaria Citrea) in Southwestern Missouri
… Missouri in 2014 and 2015, using wooden nesting boxes. Data were collected on clutch and brood sizes, the numbers of young fledged, parental care and male singing rates. Five pairs were studied over the course of the two summers. Of 28 eggs laid, 14 young fledged. In 2015, significant …

Nesting Success of Grassland Birds in Fragmented and Unfragmented Landscapes of North Central South Dakota
… that species occurrence, density and breeding success is higher in large, unbroken habitat patches, the surrounding landscape likely plays an important part in habitat quality. The main objective of this study was to assess the nesting success of grassland birds in relation to habitat patch …

Nesting Success of Dickcissel (Spiza americana) and Non-breeding Grassland Bird Use of Northwest Arkansas’ Remnant and Restored Tallgrass Prairies
… grassland species are present at these sites, nesting success and non-breeding use are still largely unknown. Both life history aspects are required for effective grassland bird conservation. My first objective was to access nest success of the Dickcissel (Spiza americana) at two remnant and …

Abundance and Nesting Success of Acadian Flycatchers (Empidonax Virescens) at Different Scales of Fragmentation in Illinois, United States of America
… rather than fragmentation may influence nesting success and populations. I measured nest concealment, complexity and heterogeneity of vegetation in the vicinity of the nest, and the plant communities in which the nests were located. Acadian Flycatcher nesting success increased with …

Effects Of A Shore Protection Project On Loggerhead And Green Turtle Nesting Activity And Reproduction In Brevard County, Florida
Marine turtle reproductive success is strongly correlated with the stability and quality of the nesting environment. Because females show fidelity to key nesting beaches, the management and physical characteristics of these beaches directly affect future generations of marine turtles and may be …

Factors Affecting Songbird Richness, Abundance, and Nest Survival in Riparian Forests in a Midwestern Agricultural Landscape
… of various spatial and temporal scales on the nesting success of songbirds. I found that the forest type was the most important variable in determining nesting success of canopy nesters, while landscape-scale factors were most important for shrub-nesting birds. Canopy nesters placed nests more …

Estimating the Impact of House Sparrows on Eastern Bluebird Reproductive Success Across an Urban Gradient
… America, where it usurps nests of native cavity-nesting birds, frequently destroying eggs, and killing nestlings and adults. This two-year study investigated habitat effects as well as the impact and management of HOSPs on the reproductive success in Northeast Ohio of the Eastern Bluebird (EABL), …

Waterfowl Production On Three Types of Artificial Nesting Structures in South Dakota Wetlands
Artificial nesting structures are currently being used by various agencies to offset the decline in waterfowl production due to predation losses and degradation of nesting habitats. However, the various structure types available are not equally attractive to nesting waterfowl. This study looked at …

Ecology and Conservation of Birds of Pinyon -Juniper Woodlands
… drought, and 2005, a wet year, I studied avian nesting success on study plots with different levels of pine mortality. Nest predation rates were low, and no species showed any difference in nest success rates across the three sites. Grey flycatchers (Empidonax wrightii) had higher nest success …

IMPACTS OF BLOODBORNE PATHOGEN INFECTIONS ON BREEDING ECOLOGY AND SUCCESS IN WHITE-THROATED SPARROWS (Zonotrichia albicollis)
… pathogen infections may have negative impacts on nesting success, such as decreased numbers of offspring, hatching probability, and fledging success. In species with multiple reproductive strategies, pathogen infections may have different impacts based on the role of the infected parent. …

Waterfowl Use and Production of Artificial Nesting Structures and Hay Bales in South Dakota
… populations have renewed interest in artificial nesting structures as a means to increase waterfowl production in the Prairie Pothole Region. I evaluated waterfowl use and nesting material durability of 3 types of artificial nesting structures and hay bales in 16 eastern and north-central South …

Nesting ecology and conservation of shrubland birds in a fragmented urbanized landscape in northeastern Illinois
… highlight the importance of understanding the nesting ecology of shrubland birds. The majority of the literature on shrubland birds has focused on communities in regenerating forest areas following silvicultural practices. Little information exists regarding nesting ecology and success of …

Determining the effects of non-native brook stickleback (Cualea inconstans) on the lentic systems at Turnbull National Wildlife Refuge, Cheney, WA
… characteristics that are important for waterfowl nesting success. From April-August 2015, I compared the macro invertebrate and macrophyte community characteristics, fingernail clam population and stress metrics, and water quality parameters in twelve lentic systems on the refuge; those that …

Avian breeding ecology in soybean fields: does no-till provide any benefits?
… to regional bird populations. I compared the nesting success and avian communities in tilled and no-till soybean fields. I found significantly higher densities of birds in no-till fields than tilled fields but no differences in avian communities. Of the 114 nests found, 99 were in no-till …

Going through the motions : the impacts of frequent fires and grazing pressure on reproduction of Montane grassland birds
… as a cause for the decline of many grassland-nesting birds across the globe. While this effect has motivated extensive research and conservation in the developed northern hemisphere, it remains poorly addressed in southern hemisphere. Between 1998 and 2001 I examined the effect of fire …

A Turkey Nesting Study in Gregory County, South Dakota
… were monitored during the study. Average adult nesting rate was 42% (31% in 1984 and 54% in 1985). No juveniles nested either year. Nesting success in 1984 and 1985 was 80% and 0%, respectively. Data was collected from 8 woodland and 5 grassland nests. Nest initiation dates ranged from 20 April …

An Experimental Study of Behavioral Responses to Nest Predation and Brood Parasitism in a Migratory Songbird
… traits that maximize lifetime reproductive success and that these traits will include behavioral responses to factors limiting reproductive success. These behavioral responses may be especially important for birds breeding in highly fragmented landscapes where brood parasitism by …
