The Influence Of The Sensory Environment On Avian Reproductive Success And Human Well-Being, Danielle Marie Ferraro
The Influence Of The Sensory Environment On Avian Reproductive Success And Human Well-Being, Danielle Marie Ferraro
Master's Theses
Sensory pollutants such as anthropogenic noise and night lighting now expose much of the world to evolutionarily novel sound and night lighting conditions, which can have detrimental effects on humans and wildlife. In my first chapter, we exposed wild Western Bluebird (Sialia mexicana) nestlings to noise, light, and combination (i.e., noise and light) treatments. Nests exposed to noise and light together experienced less predation than control and light-exposed nests, and noise-exposed nests experienced less predation than control nests, yet overall nest success was only higher in noise-exposed nests compared to light-exposed nests. Although exposure to light decreased nestling body condition …
Influences Of Anthropogenic Noise On Flight Initiation Distance, Foraging Behavior, And Feeder Community Structure Of Wild Birds, Alissa R. Petrelli
Influences Of Anthropogenic Noise On Flight Initiation Distance, Foraging Behavior, And Feeder Community Structure Of Wild Birds, Alissa R. Petrelli
Master's Theses
Throughout the world, birds represent the primary type of wildlife that people experience on a daily basis. However, a growing body of evidence suggests that alterations to the acoustic environment can negatively affect birds as well as humans in a variety of ways, and altered acoustics from noise pollution has the potential to influence human interactions with wild birds. In this thesis, I investigated how anthropogenic noise impacts daily behavior as well as community structure of wild birds. In the first component of this thesis, I assessed the distance at which a bird initiates flight or escape behavior (i.e., flight …
Effects Of Experimental Noise Exposure On Songbird Nesting Behaviors And Nest Success, Tracy I. Mulholland
Effects Of Experimental Noise Exposure On Songbird Nesting Behaviors And Nest Success, Tracy I. Mulholland
Master's Theses
Anthropogenic noise is an increasingly prevalent global disturbance. Animals that rely on the acoustical environment, such as songbirds, are especially vulnerable to these sounds. Traffic noise, in particular, overlaps with the frequency range of songbirds, creating masking effects. We investigated the effects of chronic traffic noise on provisioning behaviors and breeding success of nesting western bluebirds (Sialia mexicana) and ash-throated flycatchers (Myiarchus cinerascens). Because anthropogenic noise exposure has the potential to interrupt parent-offspring communication and alter vigilance behaviors, we predicted that traffic noise would lead to changes in provisioning behaviors, such as fewer visits to the …
