Subject: [AZNMbirds] Buff-collard Nightjars: Access for Brown Canyon in the Baboquivari Mnts
This communication has been reviewed and approved for public view by Buenos Aires National Wildlife Refuge Management (520) 823-4251, general inquiries ext 101. Details are provided here for areas of public access of Brown Canyon and Brown Wash, map is provided. Brown Canyon Rd, leading to Brown Canyon, is located 20-1/2 miles south of Hwy 86 and Hwy 286 intersection at Robles Junction (Three Points).

On June 11th, Susan Sferra of the USFWS and I recorded BUFF-COLLARD NIGHTJARS within Brown Canyon, a known summer resident of the canyon. Subsequent informal surveys by Brian Nicholas and myself, in June, have confirmed a robust population of BuffJars within the canyon. Importantly, the population extends well outside the USFWS canyon no-access boundary, extending eastward along Brown Wash and a section of Brown Canyon Rd. This makes public access from Brown Canyon Rd, (#102), to the BuffJars possible. Details below provide restrictions and access details.

Parking and listening for the BuffJars on Rd 102 within Buenos Aires National Wildlife Refuge boundaries is permitted but there are some details to know, see detailed map. THE BEST LOCATION: After the third cattle guard along the Rd #102, to the security gate (3-1/2 miles from Hwy 286) that prevents public access to the canyon, is the more likely location for successful BuffJar detection but they have been heard at all three cattle guards.

Photo opportunities will be limited as the better habitat is not adjacent to public access along Rd 102 (see map link below). IMPORTANT: BANWR Rd 148 requires -high- clearance and a willingness to have your vehicle’s paint altered but the road does parallel much of lower Brown Wash, west most reach of the road being the good habitat for BuffJars as they have been frequently heard from the Rd 102/148 intersection westward.

-DO NOT ACCESS BY FOOT OR BY VEHICLE- the private land holding north of Rd 102 as shown on the map (between cattle guards #1 and #2). DO NOT ENTER the roads leading to holding's coral and watering facility. Faded signs indicating “Stay Out” are posted but could be easily missed. Access to State Trust Land must be done with proper state permits.


The road is ok for passenger vehicles; past the second cattle guard the road does become progressively rougher but I’ve had my Corolla on this road many times without issue (fair and dry weather). Turn-around spots after the third cattle guard are at or near the security gate.
