The Kitsap Audubon Society will host “Avian Evolution: How Birds Got to Be Birds,” by master birder and noted author Connie Sidles from 7-9 p.m. Jan. 11 at the Poulsbo Library Community Auditorium, 700 NE Lincoln Road, Poulsbo.

Let Sidles take you back in time when dinosaurs roamed the Earth and nature began to experiment with a new approach to flight: birds. Exciting new fossils of extraordinary detail are being found in huge numbers in northeast China, dating back to the cusp of time when dinosaurs had begun to evolve into birds. At the same time strange and wondrous, these creatures — and others being discovered all over the world­ — open our eyes to the ways that evolution has shaped the biome and its birds that we enjoy today.

Sidles is a perennial favorite at Kitsap Audubon, and keeps returning with more wonderful stories about birds and birdwatching at her “favorite place on earth” — the Montlake Fill, also known as the Union Bay Natural Area. She led a Kitsap Audubon field trip there.

She has authored numerous books and countless articles. She has been managing editor of many publications, including Bulletin of the Atomic Scientists, the Adventure Travel Trade Association, Teleflore and Pacific Northwest magazine. She graduated Phi Beta Kappa from the University of Chicago with a degree in Egyptology.
