Birdy Hour Speaker Series with Tyler McFadden Birds in a Changing Bay Area – Long-term Trends at Jasper Ridge

May 6, 2021 @ 5:00 pm - 6:00 pm

| $5
Birds are integral parts of Earth’s ecosystems and are excellent indicators of ecosystem health. However, recent continent-wide analyses of bird populations report dramatic, widespread declines across many species. In this talk, PhD candidate Tyler McFadden will discuss ongoing research assessing the status of bird populations at Jasper Ridge Biological Preserve, located in Silicon Valley’s rapidly urbanizing backyard. Thirty years of bird survey data collected here indicate that a surprising number of common birds are declining. Tyler will discuss long-term changes in the local bird community, the underlying drivers, and the potential consequences for people and ecosystems.
Tyler McFadden is a PhD candidate in the Department of Biology at Stanford University, where he studies human impacts on biodiversity. His research focuses on how ecological communities respond to these impacts and seeks to identify practical strategies for conserving biodiversity in human-dominated landscapes. Tyler has a B.S. in Fisheries and Wildlife Science from Oregon State University and has studied birds in California, Oregon, Chile, Mexico, Honduras, and Costa Rica. Tyler is passionate about environmental education at all levels and loves sharing his enthusiasm for the outdoors with his students. Check out his website and follow him on Twitter.
