Visiting the IBA: From the town of Arivaca drive south on the Ruby Road for less than 11 miles and take the second FR 217 turnoff that is prominently marked by a Forest Service “CALIF. GULCH” sign. The road is rugged and requires a high clearance vehicle. Audubon chapters occasionally lead field trips to this IBA. Detailed instructions can be found in the book Finding Birds in Southeast Arizona.

California Gulch has a small but consistent population of Five-striped Sparrows (10 to 15 pairs), a Species of Conservation Status (National PIF Watchlist). This species probably has the smallest regularly occupied breeding range of any bird in the U.S. (excluding island nesters), which is localized to the Pajarito Mountains and Patagonia Mountains (and sometimes the southern Santa Rita Mountains This IBA has probably the best habitat for Five-striped Sparrow within their U.S. range. Additionally, the canyon supports nesting Gray Hawk, Montezuma Quail, Yellow-billed Cuckoo, Tropical Kingbird, Black-capped Gnatcatcher, and Lucy’s Warbler (very abundant), all of which are Species of Conservation Status. The canyon also supports Buff-collared Nightjar (3 pairs, M. Stevenson pers. com.) a rare species in Arizona.
Cattle grazing in the area is an impact to the riparian vegetation, causes erosion, and degrades stream water quality. Illegal immigrant passage and drug smuggling are serious concerns, affecting both habitat quality and human visitor safety. Past mining activities may be a concern due to soil/water contamination.
