Wetlands Tours--Guided public tours of the Bolsa Chica wetlands will be held Saturday morning. The tours, sponsored by Amigos de Bolsa Chica, will depart from the wetlands’ ecological reserve every 20 minutes beginning at 9 a.m. The last tour will depart at 10:30 a.m.

Bolsa Chica is one of the best bird-watching sites in the county. Birds likely to be seen on the tours include egrets, loons, herons, grebes and other waterfowl.

Those who would like to take the 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.

Children’s Summer Series--The Sea & Sage chapter of the National Audubon Society is sponsoring a program titled “Audubon Summer Science Adventures for Children” at the San Joaquin Wildlife Sanctuary in Irvine beginning July 12.

The weeklong classes will be offered from 9 a.m. to 1 p.m. daily July 12-16, July 19-23, July 26-30 and Aug. 2-6.

Children will explore all aspects of birds and bird-watching, including how to identify birds, their songs and calls, habitats and nests, feeders and baths, feathers, flight and migration.

Daily activities will include field walks, guest speakers, games and a take-home craft.

The program is open to children in the fourth, fifth and sixth grades.

The fee is $65 each child for a one-week session; a second child from a family may enroll for $60.
