March 6, 2026 -Lecture: “I May Still Be Speaking” – Indigenous Oral Tradition of Northern Baja California
Lecture: “I May Still Be Speaking” – Indigenous Oral Tradition of Northern Baja California
Speaker: Michael Wilken-Robertson, Anthropologist
Indigenous people of northern Baja California share ancient cultural and linguistic ties with other Yuman groups of southern California and Arizona. Over the millennia, native peoples developed richly elaborate cosmologies in which the earth, sky, plants, and animals were infused with spirit; these narratives were passed along through myths, legends, stories, and song. In this lively talk, we will hear examples of storytelling from the Kumeyaay, Paipai, and Kiliwa peoples that Wilken-Robertson has worked with for over 40 years in Baja California. The narratives will be considered in their cultural context to help us better understand the meanings embedded in them and why the particular narratives passed down for generations remain compelling to listeners today.
Anthropologist Michael Wilken-Robertson has developed lifelong collaborative relationships with native artists and traditional authorities to foster cultural revitalization and sustainable community development in northern Baja. He has taught in the anthropology department at California State University, San Marcos. His fascination with native plants and the natural landscapes of the Californias have inspired him to explore the many ways that humans have interacted with their environments, from the ancient past to the present. Michael resides in Ensenada, Baja California, Mexico. In the ABDNHA Library. GP $12, M $10, V $8. Register online, or call us at 760-767-3098.

Talk & Walk: Plants of Anza-Borrego
Leader: Don Rideout, Coordinator, Desert Botany Club
Short Lecture and Field Trip (Easy walk, okay for all vehicles)
An offering of the new Botany Club, these walks will focus on the plants of Anza-Borrego Desert, with locations varying depending on where we find the most interesting plants. Our pace will be generally slow, allowing plenty of time for plant identification, questions, discussion, and photography. All levels of knowledge are welcome, including children. Meet at ABDNHA; carpool as best we can, as we head to the field trip site. No Charge. Space is limited. Register at the Nature Center or call 760-767-3098.
Lecture: Native Bats of Anza-Borrego Desert State Park
Speaker: Don Endicott
Don is a volunteer naturalist with a special interest in bats and bat research. He records bat echolocation sounds and submits them to the San Diego Natural History Museum's acoustics collection, as well as for research and analysis in commercial bat software. Don began conducting this acoustic research on the park's bat population in early 2020, following a fire in Borrego Palm Canyon. If time and conditions permit, he will lead the group outdoors after the lecture to see if he can detect the calls of active bats. At the ABDNHA Library. GP $12, M $10, V $8. Register online, or call the Nature Center at 760-767-3098.
