Birds of Winter with Ed Harper

January 10, 2018

Please note: the Field Study portion is now full. We are still accepting registration for the Seminar series.

Program description: Whereas some of our birds such as swallows, flycatchers, and warblers do migrate south for the winter, many more birds flock to the Sacramento region to spend the winter.  Cranes, ducks, geese, gulls, raptors, kinglets, and sparrows are just a few of the many representative groups residing here during the winter months.  Whether you simply want to distinguish one sparrow species from another or seek greater help in learning the distinctive “churt” note of a Hermit Thrush, this course has broad appeal.  Anyone who has a serious interest in birds and enjoys their presence in our lives can profit from this class.

Speaker bio: Ed Harper leads this exciting program each year for the Effie Yeaw Nature Center. Ed has a passion for birds, wildlife, and photography. His birding interest goes back to age 6 when he was growing up in Montana. Now retired from a career in teaching mathematics at American River College in Sacramento, he teaches birding classes and leads tours throughout the world. Favorite destinations are East Africa and Montana.
