| Multiple Stressors Shape Bluebird Development and Maternal Behavior Across Urbanization Gradients Erin Murray, Jason Keagy. The Pennsylvania State University, University Park, Pennsylvania, USA |
Abstract
As cities expand, wildlife is increasingly exposed to anthropogenic stressors such as noise pollution and high temperatures. Many anthropogenic stressors jointly affect wildlife, yet are often studied in isolation, so it is largely unknown how multiple stressors affect animals in combination and whether there are interactive effects. My research addresses this knowledge gap using Eastern bluebirds, which were once in major decline from habitat loss, but have rebounded due to artificial nest boxes. I am assessing how heat and noise affect maternal care behavior, how heat and noise affect nestling growth and fledge timing, and how urbanization relates to adult learning performance and neophobia. My study takes a novel approach by utilizing Raspberry Pi camera systems for continuous, remote monitoring of female incubation and provisioning, as well as a novel operant conditioning device with a mechanical sliding door and two perches (one “correct” and the other “incorrect”) to test learning. The results of this study will provide critical information about how co-occurring anthropogenic stressors interact to affect wildlife behavior in an increasingly urbanized world
