Join us on Thursday November 15 in San Francisco for a spotlight on the roots of ornithology — how Charles Darwin changed our understanding of birds, the passionate debates that led to today’s classification of bird species, and what it was like to be a natural scientist at the dawn of the 20th century.

Our featured guest speaker is Daniel Lewis, author of the book “The Feathery Tribe,”  a biography of Robert Ridgway, the Smithsonian’s first curator of birds.  For more information, see our Speaker Series page.
