The Backyard Birding series continues at 10 a.m. Saturday, March 2, at the Dungeness River Audubon Center at Railroad Bridge Park, 2151 W. Hendrickson Road.

Shirley Anderson and Ken Wiersema will present “Birds: The Inside Story (Bird Anatomy and Biology),” the sixth in the series.

This seminar includes information on the physical features and biology of birds—how they eat, digest, breathe, sing, reproduce and fly. Participants learn from a collection of bird skeletons, feathers and feet along with new graphic illustrations and recorded sounds.

Hosted by members of the Olympic Peninsula Audubon Society (OPAS), the 10-class Backyard Birding series offers interested local residents information about observing and protecting wild bird life in the region.

Backyard Birding can be taken either as individual classes or in a series. The cost of each session is $5. Admission is free for anyone younger than 18.

For participants completing five sessions in the series, OPAS offers a free, one-year membership.
