Notes about your surroundings

Trestles Trip--South Coast Audubon, a chapter of the National Audubon Society, will take a field trip Saturday to the Trestles area south of San Clemente.

The willow riparian and marsh habitat attracts yellow-breasted chats and warblers, chapter officials say. Swallows, common moorhens and California gnatcatchers may also be spotted in the sage scrub near the beach.

The group will meet in the beach parking lot at El Camino Real and Cristianitos Road, off Interstate 5 near San Onofre State Beach.

The trip will begin at 8 a.m.

Young Audubons--South Coast Audubon will also have a Young Audubons program Wednesday.

Springtime flowers, trees and birds will be the topic of the program, which begins at 6 p.m. It is free, and children age 5 to 12 are welcome.

The program will be at the Boys & Girls Club, 1304 Calle Valle, San Clemente.
