Bear Divide is a narrow pass in the San Gabriel Mountains, just outside of Los Angeles, that is home to spectacular dawn flights of migrating birds in the spring. With thousands of migrants funneling through such a narrow corridor, this is a unique biological phenomenon. In 2021, the Moore Lab of Zoology at Occidental College began a regular count to quantify the numbers and identities of birds migrating through Bear Divide. Join Dr. Ryan Terrill to learn about the status of spring migration across the Divide, and how you can help.

Currently working at the Moore Lab of Zoology at Occidental College, Dr. Terrill received his B.S. from UC Santa Cruz and his PhD from Louisiana State University. He has studied the evolution of bird molt, an incredible adaptation that allows birds to drop and regrow worn feathers each year, and as the lead on the Mexican Bird Resurvey Project, he used big biodiversity data and genomic tools to understand how a century of human-caused change has impacted bird communities. Dr. Terrill is one of the top experts on local birds and serves on the California Bird Records Committee, the group which compiles the state bird list and rules on new records.
