Mitchell Canyon, on Mount Diablo’s northern flank is one of the best examples of mid-elevation riparian habitat in the East Bay.  Along with numerous avian residents, spring brings an assortment of neotropical migrants including warblers, vireos, flycatchers, tanagers, grosbeaks, and hummingbirds.  The canyon is also famous for its spring butterflies and wildflowers, including the rare endemic Mount Diablo globe lily (also called fairy lantern).
