Southeast Arizona Rare Bird Alert

This update of Tucson Audubon Society’s Rare Bird Alert for Southeast Arizona was made on May 22, 2020. The next update will be made on May 29.

SEVERAL IMPORTANT ANNOUNCEMENTS follow the sightings, including information on temporary closures and rules for access to other important birding areas. Abbreviation “m.ob.” = multiple observers. An asterisk (*) preceding a species name in the list indicates that it merits careful, full documentation. A pound sign (#) indicates that brief corroborating details are warranted.

#American Golden-Plover
#Laughing Gull
#Buff-collared Nightjar
#Berylline Hummingbird
#Lucifer Hummingbird
#Green Kingfisher
#Black-capped Gnatcatcher
#Hooded Warbler
#Rufous-capped Warbler

A *CLAY-COLORED THRUSH continued at Arivaca Cienega ( in Buenos Aires NWR through 5/22 (m.ob.). It has been in the small cottonwood/willow grove at the end of the paved part of the rail (where it forks). It has also been seen in town, a short distance to the northwest. Early morning and evening seem to be the best time to find it at the cottonwood.

At Canoa Ranch Conservation Park an *ARCTIC TERN was seen and photographed by many on 5/18. An incredible 12 *ELEGANT TERNS were reported (and at least five photographed) on 5/19 (Nancy and Rich Willott) as they flew briefly around the pond.
A frigatebird – presumably a *MAGNIFICENT FRIGATEBIRD – was photographed along I-19 near Duval Mine Road on 5/18 (Nancy Bent, Roger Reason).
In Florida Canyon (annotated map:, #RUFOUS-CAPPED WARBLERS continued this week (m.ob.) in the West Fork near the dam. Directions: About 400 yards from parking lot is a metal gate, and just past the gate the canyon forks. The main trail follows the East Fork, but most sightings have been in the West Fork to the right. About 125 yards up the rough trail in the West Fork is a large water tank and a low dam. The oak grove is about 1/3 mile past the dam. Note: The trail for the West Fork can be difficult to find, and is steep and rough in places. If you see the sign with distances to Florida Saddle, Madera Canyon, etc you’ve missed the turn. It is not necessary, recommended or permissible to enter the research station to see these birds. #BLACK-CAPPED GNATCATCHERS continued in Florida Canyon this week (m.ob.); they’ve been seen near the Florida Canyon parking area and a short distance up the trail, and at the old corral at FR488 & 62A.
In Madera Canyon (map:, a #BERYLLINE HUMMINGBIRD continued at the Santa Rita Lodge this week through 5/22 (m.ob.).
In Box Canyon (map:, a #LUCIFER HUMMINGBIRD continued on 5/21 (m.ob.).
In Montosa Canyon (annotated map: #BLACK-CAPPED GNATCATCHERS continued this week (m.ob.) near the culvert, upstream of the concrete stream crossing.
A #HOODED WARBLER was photographed on 5/15 (Ethan Beasley) in Agua Caliente Canyon and continued through 5/19 (m.ob.). It was about 1/2 mile up the trail just past the Mt. Wrightson sign.

An *ARCTIC TERN – almost certainly the one seen the day before in Green Valley – was seen and photographed by many at Columbus Park on 5/19 (m.ob.).

PORTAL & the CHIRICAHUAS (annotated map:
*CRESCENT-CHESTED WARBLERS continued in Morse Canyon this week (m.ob.). Map:
#LUCIFER HUMMINGBIRDS continued in a yard in Whitetail Canyon this week (Rick Taylor).
In Portal, a #HOODED WARBLER was recorded singing at Cave Creek Ranch on 5/20 (James Petersen).

A *GLOSSY IBIS was photographed at Lake Cochise by the Twin Lakes Golf Course in Willcox on 5/20 (Dave Stejskal, Gary Rosenberg) and continued on 5/22 (m.ob.). A #LAUGHING GULL was photographed on 5/19 (Susan Patla). An *AMERICAN GOLDEN-PLOVER was reported on 5/16 (m.ob.) and one was photographed on 5/18 (Arlene Ripley). A #WHIMBREL was photographed on 5/20 (m.ob.).

In Miller Canyon, a *FLAME-COLORED TANAGER continued from just past the sign for the Hunter Canyon trail this week (m.ob.). A female and possibly a second male were reported as well. A #RUFOUS-CAPPED WARBLER was reported again on 5/18 (Forrest Rowland) about 100 yards before Split Rock (about a mile from the parking area). A #WHITE-EARED HUMMINGBIRD was photographed on 5/17 (B rad Clemens).
#LUCIFER HUMMINGBIRDS continued at Ash Canyon Bird Sanctuary (m.ob.). and in several yards on the east flank of the Huachucas this week (m.ob.)
In Huachuca Canyon, a #HOODED WARBER was photographed at the 1.7-mile parking area on 5/18 (Bob & Bettina Arrigoni).

TUBAC area (annotated map:
Multiple *ROSE-THROATED BECARDS continued about 0.7 miles north of the Tubac bridge this week (m.ob.).
A #GREEN KINGFISHER continued along the Santa Cruz River between Santa Gertrudis Lane and Clark Crossing Rd this week (m.ob.).
#BLACK-CAPPED GNATCATCHERS continued from Salero Ranch (private) on 5/20 (Curtis Smith, Sue Carnahan) in the foothills east of Tubac.

A female *ROSE-THROATED BECARD was reported again along Blue Haven Rd on 5/17 (m.ob.) near Temporal Gulch – this is southwest of the entrance to the Patagonia- Sonoita Creek Preserve; annotated map:
A #GRAY CATBIRD continued in a Patagonia yard on 5/11 (Kathy West).
ACCESS NOTE: The Paton Center for Hummingbirds is closed through June 30.

#BUFF-COLLARED NIGHTJAR continued in the Brown Canyon section of Buenos Aires NWR ( on 5/22 (m.ob.). on the publicly accessible (east) side of the gate. There are three cattle guards on Brown Canyon Rd (#102) leading up to the security gate, which is 3.5 miles from Hwy 286. In past years the best location for hearing a nightjar is between the third cattle guard and the gate but they have been heard at all three cattle guards.
Photo opportunities may be limited as the better habitat is not adjacent to public access along Rd 102 (see map here
Another area is along BANWR Rd 148 (high clearance recommended) – the turnoff is just before the first cattle guard.
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 the 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.
For details regarding access to the restricted area (west of the gate) contact the refuge headquarters (520.823.4251 ext 101).

A #SHORT-TAILED HAWK was photographed at the Jesus Goudy Campground (near Riggs Lake) on Mt. Graham on 5/19 (Caleb Strand).

#LUCIFER HUMMINGBIRDS, #BLACK-CAPPED GNATCATCHERS and a #RUFOUS-CAPPED WARBLER continued on the Guindani Loop Trail at Kartchner Caverns State Park this week (m.ob.).


Good birding!

Directions to Birding Sites
Where directions are not given, they can be found in the newest edition of Finding Birds in Southeast Arizona, published by and available from Tucson Audubon Nature Shop.

Methodology of this Report
The sequence of sightings in this report is not random. Species are listed by order of overall rarity within locality. The first locality mentioned contains the rarest species seen during the reporting period. Within that locality, species are mentioned in relative-rarity order or in taxonomic order, if relative rarity is the same, within sub-locality. When the sightings for a locality are complete, the rarest remaining species dictates which locality is mentioned next, and so forth. At any point when 2 or more species are of the same relative rarity, taxonomic order then determines the sequence in which the localities are covered. Consequently, the order in which localities are mentioned will vary from one report to the next.

Contributors are listed in the text. The spelling of names given over the phone is not guaranteed to be accurate. Any errors or omissions are unintentional.


The revised 8th edition of Finding Birds in SE Arizona (2015) is the current edition. Addendum to the revised 8th edition is available at:

TUCSON – Mosquito control operations are scheduled at Sweetwater Wetlands from 6:30-9:00 am on Mondays.  The gate will open when operations are finished. Roger Road WRF was closed as of 1/10/2014 and it is uncertain when access will be allowed again.

The gravel pit at the south end of Renaissance Ave may be viewed from outside the fence, but do not enter the pit. Similarly, the fields at the intersection of nearby Indian Agency Rd/Los Reales Rd. may be viewed from the road, but the pit is posted “No Trespassing”.

EL RIO OPEN SPACE PRESERVE/COACHLINE GRAVEL PIT – park in the dirt lot along the south edge near the berm, not in the neighborhood to the west. Annotated map:

GREEN VALLEY WRF – Under construction, access on weekends only for now. Protocol for visiting when open: use the call box at the gate, sign in at the office on the west side of the complex before birding, and stay away from buildings and construction equipment. If gate is open, proceed to office to sign in. Sign out when finished. If you’d like to call ahead, you can try at 520-625-0025. Map:

ASH CANYON – open dawn to dusk EXCEPT Thursday, when open noon to dusk. Parking is limited; please carpool whenever possible. No need to call ahead.

PATAGONIA – Patagonia Ranch Estates has posted signs that say “No Hunting – No Camping – No Parking” but birders may continue to look along Circulo Montana for grassland sparrows according to Alan Schmierer (July 2017). This is the neighborhood on the west side of the Patagonia Lake State Park entrance road.

FORT HUACHUCA – is an active military installation and will suspend your driving privileges on Post for 30 days on your first offense for talking or using a cell phone while driving. You MUST use a hands free device. Current entry requirements (subject to change without notice): US citizens should be prepared to show photo ID for everyone in the vehicle at the entrance, and possibly your vehicle registration and insurance as well. In the past, foreign nationals needed an approved military escort; if this policy is reinstated, contact the base (520.533.7111), or possibly the Sierra Vista Visitor’s Bureau (520.417.6960) well in advance.

IMPORTANT: Ft. Huachuca has posted information on access requirements on its official webpage at – look for the “Gate Information” tab on the left side of the homepage. Read the information at the “Visitors Access” button. If you click the “Installation Access Forms” button, you can see the information you’ll have to provide to get access. The Visitor Control Center is located at the Van Deman Gate on Hwy 90 and opens at 5:00 am.

ACCESS NOTE: apparently some states driver’s licenses do not meet federal requirements for base entry (IL, MN, MO, NM, and WA); see for details.

ACCESS NOTE: Despite the signage, as of March 2016 Garden Canyon was indeed now open to vehicles up to the upper picnic area and foot traffic beyond this. As of late July 2016, it was reported that it was open all the way to the top.

SANTA CRUZ FLATS – Management at the Evergreen Turf Sod Farm has asked birders not to drive into the property (i.e., the 2750 road); birding from perimeter roads (i.e., Tweedy or Pretzer) is still fine.

BAIRD’S SPARROW HILL AND THE VACA RANCH CORRAL in the San Rafael Valley is off limits to birders due to the thoughtless actions of a few birders. DO NOT ENTER THE PROPERTY.  A sign has been posted previously stating that “stopping within 0.25 mile of the corral is prohibited.”

The Regional Wastewater Reclamation Department’s  security procedures and rules are subject to change any time. Please see this link for important information regarding access: Your cooperation is greatly appreciated.

  • AVRA VALLEY WRF: Gates open at 6AM and close PROMPTLY at 2PM (do not linger, you will be locked inside). UPDATE: under construction; if the gate is locked, use the call box to request access (not guaranteed). Due to ongoing construction, birders are advised to call ahead at 520-577-7341 to check on access.
  • ROGER ROAD WRF: closed
  • NOGALES STP: closed
