Effects of climate, habitat, and biodiversity on reproductive performance in an aerial insectivore, the Tree Swallow, in Massachusetts with Dr. Lucy Zipf

North American avian aerial insectivores, including the Tree Swallow (Tachycineta bicolor), are undergoing dramatic population declines. These declines span multiple species of diverse life histories, and thus may be driven by the large-scale environmental changes caused by humans. Here we first investigate trends in Tree Swallow reproductive performance over the last three decades, and then test the hypothesis that declines in aerial insectivore reproductive success caused by anthropogenic changes in the breeding habitat, including climate change, decline in insect prey populations, and land management regimes, are contributing to overall population decline.
