KELSEYVILLE, Calif. – The Redbud Audubon Society will hold its monthly program meeting on Thursday, Nov. 15, starting at 7 p.m. at the Presbyterian Church Social Hall, 5430 Third St. in Kelseyville.

The program will feature naturalist David Lukas with a slide presentation of “The Mystery of Birdsong.”

Lukas will share his insights into the magical world of birdsong – from the ways we study birdsong, to the anatomy of how birds produce sounds, to some of their social behaviors.

Lukas’s presentation includes images of birds, visual representations of their songs and recordings of birdsongs that exemplify his talking points.

His talk focuses not on how to identify birds by their sounds, but how to understand different types of bird calls we hear and the social behaviors behind those calls.

Lukas is a naturalist and author and has been leading bird trips in California for 20 years, explained Redbud Audubon Society President Marilyn Waits.

Lukas has traveled widely throughout California and internationally. He has conducted several research projects for the Point Reyes Bird Observatory and currently lives near Yosemite National Park.

The monthly Redbud Audubon programs are free and open to the public.
