Children’s Nature Fair--The sixth annual “Children’s Discovery Faire” at the Oak Canyon Nature Center in Anaheim will be Sept. 8. The fair features exhibits and demonstrations from groups in the county that offer natural history, science and cultural programs for children.

The fair gives parents a chance to see what programs focusing on nature and the environment are available for children, and it also gives children a chance to take part in a number of hands-on activities as well as to enjoy seeing the displays and demonstrations.

Among the exhibitors at this year’s fair will be the Santa Ana Zoo, the Discovery Museum of Orange County, the Youth Science Center and Wonders of Wildlife.

The event is free. It will begin at 11 a.m. and continue until 4 p.m. Oak Canyon Nature Center is at 6700 Walnut Canyon Road, Anaheim. Call (714) 998-8380 for more information.

Wetlands Tours--Guided public tours of the Bolsa Chica wetlands will be led Saturday morning. Hundreds of shore birds are enjoying the wetlands’ environs, and several rare bird species--among them snowy plovers, American avocets and California least terns--can be seen nesting on the man-made islands. The birds will be visible from several vantage points along the tour route.

The tours will begin at 9 a.m. and continue through 10:30 a.m. Tour groups will depart every 20 minutes beginning at 9 a.m. from the wetlands ecological reserve. The tours are sponsored by Amigos de Bolsa Chica.

Those who would like to take a tour are asked to meet at the ecological reserve on Pacific Coast Highway about half a mile south of Warner Avenue, across from Bolsa Chica State Beach.
