In this third episode of Birding & Bird Photography from southeast Arizona, I head 2 miles into a remote canyon to find a rare warbler from Mexico.

Sycamore Canyon off the rugged Ruby Road is an out-of-the-way birding location just a few miles from the Mexican border. It is a common immigrant route for those fleeing Mexico, and signs were everywhere. A Border Patrol helicopter suddenly appeared over the canyon wall and zipped right overhead. I guess the fact that I was carrying a camera, and was headed in the “wrong” direction signaled that I was just a crazy birder and not an illegal migrant.

I meet Connor and Alex on the way in. A day earlier they had helped me with info about the Berylline Hummingbird at Santa Rita Lodge, and once again they provide me with valuable info on finding another rare bird.

This time it was the Rufous-capped Warbler, a “code 3” rarity from Mexico. It is seen nearly every year somewhere in SE Arizona or Texas but usually only one or two birds. In fact, between 1993 and 2025 it was only not found in the U.S. in 1997.

After getting turned around and backtracking, I eventually find the warbler. It is a real stunner, and looks more like a Chat than a wood warbler. I enjoy some brief looks as it forages in the shrubs and small trees in the canyon.

Other highlights include a Black Vulture (small SE AZ population), Rock Wren, several Canyon Wrens (nice! I rarely have seen), singing Rufous-crowned Sparrows, Hepatic Tanager, and Western Tanager.

Herps included a brief look at a Black-necked Garter Snake, and photos of Clark’s Spiny Lizards, and Elegant Earless Lizard.

I find a DOR (dead-on-road) lifer Hog-nosed Skunk on Ruby Road.

Sycamore is a very remote canyon, and there a few things every visitor should know:

–The road in is rugged but drivable by a rental car

–The “trail” in the canyon is undeveloped at best, and it is very easy to lose the route.

–Must bring plenty of water, sunscreen, hat, etc.

–No cell service! So make sure you have a compass or other ways to navigate.

–Trail is rocky but flat. Easy in places, but tough in others.

–After about 1.8 miles the route is blocked by a cliff and a small waterfall and ledge. It takes some real scrambling to make it around this point (I did it but I was a bit turned around and had already gone past the warbler location)

Southeast Arizona Birding—August 10-16, 2025

In early August I brought Bjorn down to spend a week at his grandma’s farm in Illinois. But instead of making the 18-hour round trip drive twice in seven days, I instead flew from Peoria to Tucson for some monsoon season desert birding.

It was a bizarre pre-dawn drive on the rough Ruby Road to get to the remote Sycamore Canyon. The only cars that I saw were 7(!) Border Patrol trucks. Obviously this is a commonly used route for migrants. 

Connor and Alex, grad students at Texas A&M had arrived just before me, along with a couple Border Patrol agents on foot. They took off at a quick pace while I took my time along the trail…or maybe I should write “trail,” since it was often barely perceptible which way one should go. It is a fairly flat trail but the heat, lack of signage and uneven substrate make it a challenging journey.

Alex and Connor gave me a GPS location and a good habitat description on their way out, but Google Earth was not connecting in this remote valley and I overshot the spot. I knew it was like 1.75 miles int the canyon but I “overthunk” it and ended up doing some risky boulder scrambling to get around a steep dry waterfall slope and rock cliff.

Then suddenly a Border Patrol helicopter popped over the cliffs above and buzzed down the canyon and over my head. I know they are used to occasional birders so ignored me. Odd feeling to be in such a remote place all alone and have a helicopter check you out.

But I get it…this must be a well-used crossing point. I saw much sign of folks traveling through this canyon: abandoned canteen with home-sewn bluejean cover, tuna packets, random clothes, Red Cross blanket. 

Finally I turned around. It just didn’t feel like this was the spot Alex and Connor had described. They also said it was singing so I was listening for the song and its call chip note, which to me sounds like that of a Junco. After another sketchy rock scramble and a half mile hike back up down the canyon I heard the call note.

There it was! A male in all his glory…lemon yellow with a stout bill and namesake rufous cap. I got to spend a grand total of 37 seconds with him before he flitted off through the wash-side brush. ABA area lifer number 658! (or so…I need to redo my checklist).

Rufous-capped Warbler is a Mexican species that only rarely shows up in the U.S. and when it does, almost always in SE Arizona.

I plopped down on a rock on the hillside and just waited and watched for another 45 minutes or so, but the Rufous-capped did not show again. The Border Patrol agents did pass by but evidently did not see me only 20 yards away.

It was now getting quite hot. I met a few other die hards on their way in to find the warbler. I helped one young guy who had gotten off the trail and was a bit turned around (easy to do here!).

Other highlights: Rock Wrens, Rufous-crowned Sparrow, singing and close-up Canyon Wrens, Clark’s Spiny Lizard, Elegant Earless Lizard, and a very unexpected Black Vulture(!), an eastern species that I learned has a tiny outpost in SE Arizona including Sycamore Canyon. Also a sad but interesting find…Road-kill Hognosed Skunk.

**I am working on my YouTube videos about this Arizona trip, so stay tuned!

CACTUS IN MINNESOTA?
Yes, actually two species of Prickly Pear Cactus occur in southwest Minnesota…Opuntia fragilis and Opuntia macrorhiza. And Blue Mounds State Park is a great place to see them for yourself. No, not giant cartoon-type cactus but a low-growing cactus with GORGEOUS and HUGE yellow blossoms. They should be blooming now! To make sure, call the park office in advance.
If you squint, you can almost imagine a time when tallgrass prairie covered the endless landscapes of southern and western Minnesota. And Purple Prairie-Clover (Dalea purpurea) was part of that rich mosaic of prairie wildflowers.
This species is a legume with a taproot that may reach down 6 feet into the soil! This root system helps prevent soil erosion. It is a true prairie plant that has evolved with fire, and does not tolerate shade. Pronghorns are even known to eat it.

A looming thunderstorm provides a dramatic backdrop to these grazing Bison. Don’t let me mislead you…There is a fence around the entire herd, and they are not always visible to park visitors.

In 1961, the park added three bison from the Fort Niobrara Wildlife Refuge near Valentine, Nebraska to start the present bison herd. Today, the Blue Mounds’ herd is maintained at more than 100 bison.

Notice the deeply cut leaves and extemely reflexed ray petals of the Pinnate Prairie Coneflower (Ratibida pinnata) (sometimes called Gray-headed Coneflower). To emphasize the incredible five-foot height of this prairie native, I crouched down with my wide angle lens and put the flowering heads “in the clouds” so to speak. This photo would not have had much impact if taken at “eye-level” with the flowers.

Gray Partridge, the bird formerly known as Hungarian Partridge, are not easy to find…anywhere. So I was very fortunate to run into this breeding-plumaged male near the park. They are one of the few birds that utilize seemingly barren crop fields that surround the park. I lost the original of this image when I dropped a hard drive years ago, but fortunately I printed a 4×6. This is a scan of that 4×6 print.

A Turkey Vulture soars over the prairie at Blue Mounds State Park. This is the same tree and Sioux Quartzite outcrop as in another photo in this post.

Cliffs can be habitat too. This Great Horned Owl has made a home of the Quartzite cliffs on the east side of the park. Hiking trails parallel the cliffs along the base and also on top of the bluff.

We rarely see Great Horned Owls in flight during the day. So when this guy took off, I held down the shutter. He/she then obligingly banked to reveal the full spread of its large wings and a full tail fan. The fact that he/she peeked over his/her shoulder at me was a bonus.

RARE FIND
I found this singing Rock Wren at the top of a cliff several Junes ago. The closest this western bird regularly breeds to Minnesota would be the Black Hills of South Dakota, over 300 miles away! Unfortunately, this guy did not find a mate here and likely moved on.

Some outcrops of Sioux Quartzite are more red than others, and this one also has excellent patterning with crusted green lichens. This scene is near the drive up to the Interpretive Center. The Box Elder (I think it’s a Box Elder) adds to the composition that might be a little boring without it.

A dawn rainstorm spawned a sunrise rainbow. The clouds, 180 degrees from the rising sun, lit up a beautiful pink color. In order to get the entire arc of the rainbow, I used my 10mm lens (equivalent of a 16mm lens as it was on my camera with a 1.6 crop factor) and placed the Bison underneath. I tried everything I could think of to get him to lift his head, but to no avail. I still like this unique image.

Bison rarely run, so when I saw this stampeding herd, I quickly switched my camera settings to Shutter Priority 1/30 of a second and panned with them. I got one shot that portrays the speed of these huge animals.
