[EBB Sightings] Canyon wren in Tilden Park?

Dear Birding Friends:

A friend who divides her time between Berkeley and Southern California, 
believes she heard a Canyon Wren Tuesday while walking along Nimitz Way 
early in the morning (Nimitz Way runs along the ridgeline north from 
Inspiration Point in Tilden Park). Has anyone else heard that bird in the 
vicinity?
