Prevalence and impacts of ants colonizing active bird nests in Illinois
… microhabitats. Many organisms, including birds, mammals and social insects, build nests which create unique and suitable microhabitats for a variety of other animals. These constructed environments can protect their residents from predation and from harmful abiotic conditions. In turn, the …

Snakes as predators of bird nests: now and in a warming world
… and evolutionary biology. For most species of birds, nest predation is the primary cause of nest failure and snakes have often been implicated as important nest predators. However, in other studies snakes are absent or infrequent predators. Here, I reviewed available nest camera studies from …

Does nest size constrain clutch size? A tropical-temperate test
… size of tropical as opposed to north temperate birds has intrigued researchers for a long time. An untested hypothesis posits that higher nest predation in the tropics favors smaller nests thereby constraining clutch-size. We tested this hypothesis by conducting an experiment to test whether …

Factors Affecting Songbird Richness, Abundance, and Nest Survival in Riparian Forests in a Midwestern Agricultural Landscape
… Illinois are important breeding habitat for songbirds in an agriculturally dominated landscape. Research has suggested that songbirds are influenced by habitat at multiple scales (i.e., habitat fragmentation, edge effects, exotic species), therefore it is necessary to know which variables are …

Development of Sustainable Harvest Strategies for Cellulose-Based Biofuels: Harvest Effects on Game Bird Production
… effects of biomass harvest on nesting game birds. Specific objectives of this study in southeastern South Dakota included: (1) quantifying nest success to determine if haying treatments have an impact, (2) determining if haying treatments affect nesting density, (3) determining nest site …

Development of Sustainable Harvest Strategies for Cellulose-Based Biofuels: The Effect of Intensity and Season of Harvest on Cellulosic Feedstock and Upland Nesting Game Bird Production
… on nesting success of economically important bird species, (5) determine how vegetative structure and composition affect nesting success and diversity of economically important bird species in southeastern South Dakota. This study utilized a randomized block design with 3 haying intensities …

Assessing the relationships between pollinator-friendly plantings and birds, bats and white-tailed deer on farms in the Coastal Plain of Virginia and Maryland
… such as resident, migratory, and nesting birds (e.g., wild turkey (Meleagris gallopavo)), resident and migratory bats, and white-tailed deer (Odocoileus virginianus) are of interest to both landowners and conservation managers. First, we studied bird species diversity, presence, density, …
