Learn more about tropical rainforest widlife at the next Olympic Peninsula Audubon Society meeting, when Dr. Jim Karr presents “Hoatzins and Harpies: Birding the Amazon” at 6 p.m. Wednesday, Sept. 21, at the Dungeness River Audubon Center at Railroad Bridge Park, 2151 W. Hendrickson Road, Sequim.

Karr, Professor Emeritus of Aquatic and Fisheries Sciences at the University of Washington, is a renowned expert on tropical birds and a lifelong naturalist and teacher. He spent years studying forest birds in Central and South America, including a stint as deputy director of the Smithsonian Tropical Research Institute in Panama.

Besides birds, Karr also is a noted ecologist and creator of the Index of Biological Integrity, which uses fish and stream invertebrates to assess the health of waterways. His recent adventures include guiding Smithsonian Journeys to the Amazon Basin, where he shares exotic wildlife and unique birds with his lucky passengers.

A potluck dinner is planned for 6 p.m. (bring a dish to share, along with your own utensils), followed by the program at 7 p.m.

The program is free and open to the public. Call 681-4076 for more information.
