The Olympic Peninsula Audubon Society invited community members to join Jim Karr, University of Washington professor emeritus, for a free lecture and discussion series based on John Reilly’s book “The Ascent of Birds: How Modern Science Is Revealing Their Story.”

The series, which takes place the second Tuesday of each month, kicks off 4-5:30 p.m. on Tuesday, Oct. 13, on Zoom; register online at olympicpeninsulaaudubon.org under “Events.”

Attendees are asked to read additional information in the confirmation email for accessing the Zoom meeting.

Each session explores key concepts in bird evolution, bio-geography and special adaptations of a bird species or group. All discussions are illustrated with photos, maps and other visuals.

“Recent scientific advances, coupled with a long history of bird study, has given us new insights about the elegance of birds, their family trees, and keys to their survival,” series organizers say.

Participants are given the option of reading one or two of the book’s chapters (about 10 pages) for each session. The lecture and discussion for October will focus on one chapter: “The Hummingbird’s Story: A Route of Evanescence” (Ch. 12).
