The Saturday, Feb. 7, session of Backyard Birding meets from 10 a.m.-noon at the Dungeness River Audubon Center at Railroad Bridge Park.

Attendees will learn about bird nests, how and where birds nest, as well as the care and maintenance of nests and nesting boxes — because it is time to think about birds and spring.

The class, presented by Ken Wiersema and Shirley Anderson, shows participants how to participate in the Great Backyard Bird Count, a national annual census of bird populations which occurs over Presidents Day weekend in mid-February.

Following a short field trip to tally birds in Railroad Bridge Park, learn how to enter data in the Great Backyard Bird Count computer database.

The presentation is the fourth of the series of eight classes offered by the Olympic Peninsula Audubon Society. Families and individuals are invited to attend any or all of the sessions.

There is a $5 fee for each class for those over 18. After five sessions are attended, a free one-year membership in Olympic Peninsula Audubon Society is offered to participants.

Backyard Bird follow-on classes are: March 7, “Bird Migration”; April  18, “Spring Gardening for Birds”; May 16, “Enjoying Spring Sounds” and June 6, “Out of the Nest.”
