Webinar: Online Geology Book Discussion
A Brief History of Earth – Session 1 of 4
Presented by Geoscience Educator Don Barrie

Please join geoscience educator and ABDNHA Board Member Don Barrie for a zoom-based discussion of the book, A Brief History of Earth, by Andrew Knoll. This book is available at the ABDNHA Nature Center and our online store at www.abdnha.org/store.   Harvard geologist Andrew Knoll has written a concise and accessible book about Earth's history, which Booklist describes as "a sublime chronicle of our planet." In eight chapters (230 pages), Dr. Knoll covers the highlights of our planet's 4.5-billion-year history, beginning with Earth's origin and ending with a discussion of how humans are transforming the planet. He explains the key processes that have enabled Earth to evolve from a lifeless ball of rock into a varied, blue-green orb with continents, oceans, an atmosphere and biological life. During each meeting, participants will have an opportunity to share their thoughts about what they're learning. Don will moderate the discussion and also present a weekly PowerPoint presentation seeking to clarify the science behind Dr. Knoll's discussion points. Hope you can join us! No charge, but donations are greatly appreciated in support of ABDNHA’s programs. Online Registration is required.

Special Webinar: Golden Eagles in San Diego County
Presenter: Katie Quint, Research Director of the Wildlife Research Institute (WRI)

Join Katie Quint as she tells the story of golden eagles in San Diego County and what research has told us about these magnificent birds. Katie is the third generation of researchers working on WRI’s long-term annual eagle monitoring program, which started in 1988.  Katie became involved in 2012 and has spent many hours on the ground and in helicopters gathering data and looking for eagle nests in the desert mountains. Katie is considered a local expert on golden eagles, and her presentation will include information about reproductive activity, territory, nest distribution, and the results of the annual monitoring program. No charge, but donations are greatly appreciated. Online registration is required.
