Tree Canopy Cover Influences Habitat Use Of Breeding Birds At Jack Mountain Wildlife Management Area, Kaleigh Thomas
Tree Canopy Cover Influences Habitat Use Of Breeding Birds At Jack Mountain Wildlife Management Area, Kaleigh Thomas
Honors Theses
Across the United States, bird populations have declined due to habitat loss. To better understand habitat use by birds, researchers observed populations at Jack Mountain Wildlife Management Area in southwest Arkansas. Students at Ouachita Baptist University surveyed 94 point count locations to estimate species diversity (total number of species observed) and species abundance (total number of individuals observed). At each point, students recorded the percentage of tree canopy cover, ground cover, midstory cover, and shrub cover. These variables were used as explanatory variables in multiple regression analyses to determine which variables were influential in explaining variation in species diversity and …
Changes In Spring Arrival And Fall Departure Dates Of Migratory Birds As An Indication Of Local Climate Change: A Phenological Study Of New York State's Capital Region Using Citizen Science, Olivia C. Townsend
Honors Theses
Climate change is becoming an increasingly important topic of scientific research, and studies commonly analyze biological indicators. Migratory birds are responsive to environmental changes because life cycles depend on finding proper seasonal locations. eBird is a citizen science database launched by the Cornell Lab of Ornithology and National Audubon Society in 2002, and this study focused on eBird data to analyze migratory shifts over the past two decades for the Green-winged Teal (Anas crecca), Northern Pintail (Anas acuta), Bufflehead (Bucephala albeola), Common Goldeneye (Bucephala clangula), Common Merganser (Mergus merganser), Red-breasted Merganser (Mergus serrator), Canada Goose (Branta canadensis), Snow Goose (Chen …
Bird Mortality In The Human Built Environment, Stacie Schwartz
Bird Mortality In The Human Built Environment, Stacie Schwartz
Honors Theses
Human development is having a detrimental effect on bird populations around the world. One hundred million to one billion birds are killed every year from colliding with human-built structures. I explored factors influencing the inability of birds to avoid man-made structures. If we can better understand these reasons, we can find solutions to this problem. After a known bird avoidance method, fritted glass, was installed in the Wold building, I investigated whether this glass actually deters birds from striking windows. Strikes on windows were noted daily through observation of specific windows on campus. Results show that vegetation outside of windows …
