Lower 48 Life List Countdown: Crissal Thrasher

2 Replies

Today, we take a break in posting about our recent Costa Rica adventure to share one of Braden’s most memorable domestic birding experiences of 2026. His mission: to see a bird with very specific habitat requirements—and one that had frustrated him several times before. If you’re in Vegas for March Madness you will definitely want to read this post!

In 2025, I saw a lot of birds. Besides international trips to Oaxaca and Costa Rica, I birded across the United States and Canada in places I’d never been before—a road trip from Maine to Montana and another from Montana to southern California, with a side detour through southeastern Arizona. Not surprisingly, I racked up tons of life birds, including Whooping Crane, Roseate Tern, Kirtland’s Warbler, Buff-breasted Flycatcher and California Gnatcatcher. As 2025 came to a close, though, I started to wonder: how many regularly-occurring US species were left out there that I haven’t seen?

In considering the question, I didn’t count Hawaiian or Alaskan birds; those are species that will take extra, dedicated trips to see. I also cut out seabirds that require pelagic boat trips, a style of birding that is exclusive, expensive, and not particularly appealing to a landlubber such as myself. My list omitted rarities—birds that do not regularly occur in the United States—because I much prefer finding a species in its proper habitat as opposed to chasing a single individual bird in the wrong place found by another birder. Finally, I did not include three species that only breed in the Florida Keys—Mangrove Cuckoo, Antillean Nighthawk and Black-whiskered Vireo—because they only occur there in summer, a decidedly miserable time to visit the Sunshine State. I also believed that I’d encounter these species elsewhere when I eventually visited the Caribbean some day.

Before Braden’s return to Las Vegas, Least Bittern is one of just sixteen “regular” birds he needed to complete his Lower 48 life list.

So, by my very specific standards, I came up with the following list of regularly-occurring US birds that I had yet to see as of January 1st, 2026:

  • Least Bittern
  • Chihuahuan Raven
  • King Rail
  • Swainson’s Warbler
  • Black-chinned Sparrow
  • Fulvous Whistling-Duck
  • Connecticut Warbler
  • Golden-cheeked Warbler
  • Black-capped Vireo
  • Island Scrub-Jay
  • Smith’s Longspur
  • Colima Warbler
  • Boreal Owl
  • Lesser Prairie-chicken
  • Gunnison Sage-grouse
  • Crissal Thrasher

16 birds. 16 birds left in the US that I care about seeing that I’ve never seen before. Some of them I have pursued many times (looking at you, Least Bittern and Boreal Owl). Others, I’ve never even tried for once, because I’ve never been within their ranges. 

When I realized that I would be driving back to California after spending Christmas in Montana, however, and saw that the shortest route took me through Las Vegas, I knew that I needed to take another stab at Crissal Thrasher. This is the last US mimid (member of the family Mimidae) that I’d never seen before—and one that had frustrated me before.

Like all other US thrashers except Sage Thrasher, this Long-billed Thrasher (and the Sage Thrasher featured at the beginning of this post) belong to the bird family Mimidae. As this family name suggests, thrashers and other mimids have a remarkable ability to mimic other birds. No wonder they are some of our favorite birds here at FSB!

My dad and I had looked for Crissal Thrashers when we visited Arizona in May of 2022, in Yuma, Arizona. They were also on my target list when I visited the Chiricahuas in August of 2025, and while I did find my lifer Cassin’s Sparrow and Scaled Quail out in the desert near Portal, there were no Crissal Thrashers to be found. However, my most recent—and heartbreaking—near-miss had happened just a few weeks previously, at the beginning of December, 2025.

During one of our last weekends of work, three friends and I decided, almost on a whim, to drive four hours and camp near Death Valley National Park. On Saturday morning, my friend Sam and I snuck out of our tents early, staying quiet so as not to wake the others, and drove an hour west to a spot known for having Crissal Thrashers. The habitat featured tall, brushy vegetation growing along a desert wash. I’d later learn that Crissal Thrashers preferred this riparian desert habitat, and were much more common in this environment than out in the middle of the desert, away from water. 

The place Sam and I visited that morning in December was called Shoshone Village, nothing more than a trail looping through the desert. We started to hike and immediately spotted some of the more common Mojave Desert birds—Phainopeplas and Gambel’s Quail. As we rounded a bend and entered some more dense vegetation, Sam pulled out his phone and ran the Merlin app.

Phainopeplas greeted Sam and me on our previous search for Crissal Thrasher—a search that ended in muddy disappointment!

“Crissal Thrasher,” he said, looking at me. Suddenly, I heard what the app had been hearing—the squeaky, repeating song of a thrasher coming from around the corner. I felt disappointed that I hadn’t picked up on it—the bird was singing quite loudly—but figured that it wouldn’t matter that an app had identified the bird if we got eyes on it. Unfortunately, a large mud puddle sat in the trail between us and the thrasher.

I carefully made my way around the edge of the slippery puddle, moving thorny branches out of the way and stooping underneath thick tree limbs. After about a minute of careful effort, I reached the other side, turning around to help guide Sam around it. Sam followed in my footsteps until halfway around the puddle he suddenly slipped into the mud puddle with a splash! Not only was Sam soaked and muddy (including the large seagull onesie he was wearing), but the commotion of us trying to avoid the puddle caused the thrasher to stop singing.

We never saw the bird.

Flash forward to the Clark County Wetlands, only two months later. Clark County Wetlands sits on the eastern edge of Sin City, just upriver from Lake Mead, the giant, now-shrinking reservoir created when President Herbert Hoover decided to dam the Colorado River, and it just so happens to be one of the best places in Nevada to find a Crissal Thrasher. The presence of year-round water (a rare commodity in these parts) in the Las Vegas Wash allows for the existence of perfect thrasher habitat, complete with more extensive, green vegetation than can be found elsewhere in the Mojave.

It was a decidedly odd experience searching for on of my last Lower 48 bird species within sight of perhaps the most “unnatural” city in North America, Las Vegas!

As I stepped out into the landscape of mesquite, palo verde, and barrel cacti, I immediately regretted wearing shorts and a tee-shirt. In contrast to the 100-plus temperatures during my last visit here, this morning I shivered in cool 45-degree air. Nonetheless, birds were far more vocal than they had been back in December. Mockingbirds called from atop the trees. Black-tailed Gnatcatchers and Verdins were in nearly every little scrap of brush. Again, there were Phainopeplas and Gambel’s Quail, as well as lots of wintering birds—Yellow-rumped Warblers, Ruby-crowned Kinglets, Northern Flickers.

Then, as I rounded a corner, I heard the song again—the same song I’d heard from the leeward side of that mud puddle in Shoshone Village. This time I was ready, with no puddle standing between me and my bounty. I bushwhacked off the trail, into the desert scrub, and soon spotted it, a long-tailed bird with a long, curving beak silhouetted against the early morning sky!

I didn’t manage any still photos of my lifer Crissal Thrasher, but this video captures the moment even better!

Me and that thrasher spent a good fifteen minutes together, with bare desert mountains looming on one horizon and the Las Vegas Strip looming on the other. Eventually, the thrasher flitted away, only to take up another perch a dozen meters away. After spending more minutes admiring it, I walked back to the trail, happy and at peace.

To be honest, that thrasher wasn’t even the coolest bird experience I had that day. As I continued along the trail, I got to watch an adult male Costa’s Hummingbird performing its flight display above my head. I found two rarities, a long-continuing Northern Parula and a Golden-crowned Kinglet that no one had reported. And from the deck of the Clark County Wetlands Visitor Center, a beautifully-designed educational building, I got to watch three Greater Roadrunners chase each other, constantly clacking their bills. The last time I’d been to Las Vegas had been a hot, emotionally turbulent week, but this morning that I spent at Clark County Wetlands was so enjoyable that it is now what I recall when I think of that gambler’s haven in the desert.

Watching a trio of Greater Roadrunners from the visitor’s center added a great bonus to seeing a bird that had frustrated me multiple times before.

Arenal for Antbirds: Birding Costa Rica, Part 2

1 Reply

Like all FSB posts, this one is written by REAL PEOPLE. Feel free to share it and support real writers and artists everywhere by shunning artificial intelligence. Despite the hype, AI is not “just a tool.” Its primary utility these days is to increase profits by putting people out of work. Don’t make it easy for the giant corporations that control it and are participating in the greatest theft of intellectual and artistic property the world has ever known.

After our surprising morning birding near San Jose’s Juan Santamaría International Airport (see our previous post), Braden and I wasted no time heading into the heart of the region where we would spend the next nine days—the northern Caribbean slope of Costa Rica. Our first destination? The flanks of Arenal Volcano.

Despite having spent more than two months in Costa Rica back in 1994 (when I was writing my books The Forest in the Clouds and Monteverde: Science and Scientists in a Costa Rican Cloud Forest), I had never before explored this region. During his semester abroad here, however, Braden had thoroughly scoured the country for birds and had put together an itinerary that would give us the most bang for our birding buck. The Arenal area—near the bustling tourist town of La Fortuna—held many avian riches, but Braden and I had one group of birds we especially wanted to see: antbirds.

The area around Arenal Volcano was the first major destination of our nine-day itinerary. Unfortunately, heavy rains greeted us during this supposed dry season!

If you’re unfamiliar with them, antbirds are a group of birds that shadow army ant swarms—not to eat them, but to snag the many other invertebrates that the swarms dislodge during their ravenous raiding parties. I had seen many ant swarms during my time in Costa Rica, but again (and tragically), that was before I became a birder and if any antbirds were around, I had cluelessly overlooked them. Braden had, of course, been more alert and seen several kinds of antbirds—but never in the classic “insect-palooza” situation one reads about in scientific narratives.

Braden and I looked forward to finding an antbird flock as much as any other birds on our trip. Note the army ants below the leaf upon which this Bicolored Antbird stands.

We got our first shot at antbirds on our second morning in the country when we birded the internationally famous Arenal Observatory Lodge & Trails, a rather pricey destination with a fabulous sweep of nature to offer visitors. Fortunately, you don’t have to book a room to bird the place, but can simply pay a fee to spend the day. Unfortunately, waves of heavy rain greeted Braden and me when we arrived. Don’t get me wrong. We still had an incredible day here, including bird lists totaling more than 100 species and a fantastic sighting of a northern tamandua, a small, incredibly shy species of anteater—a first for both of us. Alas, we got only a brief glimpse of a single antbird—a Spotted Antbird—and encountered no army ant swarms where more antbirds might be plying their trade.

On our first day of antbird searching, we saw only a single Spotted Antbird that didn’t happen to be following any army ants. Still, a gorgeous creature, verdad? (Note: the featured image at the beginning of this post shows a female Spotted Antbird!)

Still hopeful, the next morning we headed to another nearby spot, a combo nature area and zip-lining destination called Sky Adventures. And guess what? It was again pouring down rain! After spending the previous day pretty much soaked, neither of us looked forward to another day of damp garments and soggy boots. A ray of hope was that one of the Sky Adventures guides told us that he had seen antbirds only the day before and even told us where to look.

Braden wondered if he would see any life birds on this Costa Rican adventures, but quickly spotted this Black-headed Tody-flycatcher, the first of FOUR lifers he would collect this day!

In this kind of weather, we had the trails pretty much to ourselves, and we realized that there was no shortage of birds around us. I should backtrack a bit and explain that while more than a third of the Costa Rican birds I was seeing were lifers, Braden had already seen so many birds in the country that he wondered if he’d get any lifers on our entire trip. That question got answered pretty quickly as we began crossing a spectacular hanging bridge over a lush ravine. Almost immediately, Braden said, “Black-headed Tody-Flycatcher!” Sure enough, on a branch hanging over the bridge, we spotted one of the cutest birds in the tropics—and a lifer for both of us! In fact, a huge variety of amazing birds seemed to be hanging out around the bridge, and before long a yellow and black bird landed just below us. Braden got even more excited by this one. “Black-thighed Grosbeak!” he exclaimed. Ka-ching! His second lifer in ten minutes!

Braden’s second life bird of the day, a Black-thighed Grosbeak, put in a leisurely appearance just below the hanging bridge. Look closely and you can even see the black thighs—though this is still one of the worst bird names ever!

Still, we hadn’t forgotten the antbirds and pressed across the bridge and up a winding trail. And at a sharp left, suddenly, there they were. Antbirds!

I confess that it took both of us a few minutes to embrace exactly what we were looking at. Columns of army ants marched along both sides of the trail, and the antbirds skittered and skaddled all about us.

Braden, looking happily in shock at finding his best antbird mixed-flock ever!

According to Vallely’s and Dyer’s Birds of Central America, Costa Rica hosts nine species of antbirds and we recognized four working the ant columns around us. These included Bicolored, Spotted, and Zelodon’s. It also included the one we both most wanted to see. “I’ve got an Ocellated!” Braden shouted with glee—his third lifer of the day.

One of our top targets of our entire trip, Ocellated Antbirds gave us extensive, if very quick, looks for our full ant swarm visit.

Why were we so excited about this bird? All antbirds are subtly beautiful, but Ocellated has the most distinct patterns of any Costa Rican species. It sports gorgeous blue, black, and rufous colors around the face and eye, and a remarkable scalloped pattern of feathers down its back and chest. As thrilled as we were to find it, we were even more thrilled to watch what the antbirds were doing.

Only a single female Zeladon’s Antbird joined the ant swarm, and apparently these do not usually follow mixed flocks, and are not obligate ant swarm feeders. Males are black instead of brown.

Back and forth they darted snagging insects, spiders, and other arthropods that were startled by or fleeing from the army ants. Braden and I paced back and forth, mesmerized by this performance. At least fifteen or twenty antbirds surrounded us, the most abundant being the Bicolored, who were also the least shy. WATCH THE VIDEO BELOW!

Antbirds, though, aren’t the only birds that join in on following army ant columns. As we watched, we also saw Wedge-billed Woodcreepers, Northern Barred-Woodcreepers, and Fawn-throated Foliage Gleaners. As a bonus, the rain had let up by now, letting us fully enjoy what might be for me a once-in-a-lifetime spectacle. In fact, we spent at least half an hour with these remarkable birds, trying to grasp exactly what they were doing and just appreciating that things like this could still happen in the world. Finally, as the trail’s foot traffic increased, we moved on.

Woodcreepers can be intimidating birds to identify, so I relished spending time with several species at the ant swarm, including this Northern Barred-Woodcreeper.

We, of course, saw many more species on this outing—including Braden’s fourth lifer of the day, a White-throated Shrike-Tanager—but it was the antbirds that would stay with us as we headed to our next, equally spectacular destination, Caño Negro wetlands.

Nocs Pro Issue 8X42 Waterproof Binoculars (FSB Equipment Review)

2 Replies

If you read our last post, you know that Braden and I recently completed an epic birding adventure to Costa Rica. One thing I didn’t mention is that, besides offering the chance to see an astonishing variety of neotropical birds, the trip gave me the opportunity to field test an exciting new piece of equipment: the Nocs Provisions Pro Issue 8X42 binoculars. And boy, did I put them to the test!

Nocs Pro Issue binoculars feature excellent optics with one of the most stylish designs in the industry. For more information or to purchase, click here.

I must confess that I liked the Pro Issues right out of the box. As I explained in my recent review of the company’s Field Tube monocular, Nocs has put real thought into designing equipment that looks and feels different from the vast majority of products out there. The rubberized protective casing of my Pro Issues features a stylish ribbed design that is easy to grip, yet feels very comfortable to hold. Like the Field Tube monocular, these binoculars also have “pop in” caps for the objective lenses that are much more secure than any other design I’ve encountered.

With my review sample of the Pro Issues, Nocs took the trouble to send me one of their woven tapestry neck straps, and if you purchase any Nocs binoculars, I highly recommend picking up one of these, too. Not only does the strap look way cooler than standard bino neck straps, it is more comfortable against the skin—and easier to attach to the binoculars than any other design I’ve seen. As far as the build, these binoculars couldn’t feel more solid. I fortunately didn’t drop them, but felt that if I had—or if I whacked them against a strangler fig tree—they would survive unscathed.

If you purchase Nocs binoculars, I highly recommend buying the woven neck strap, which is both easy to attach and very comfortable around the neck.

When I decided to take the Pro Issues to the tropics, I realized that waterproofing would be important—but I didn’t realize how important! For about half of our trip, Braden and I endured one of the wettest “dry seasons” on record. I mean, we got dumped on—to the point where, several times, we just stood under a tree and tried to will the rain to stop. Not only did the Pro Issues take on this full exposure without allowing water to penetrate the casing, the binoculars didn’t fog up even in the worst conditions.

As you can see, the rain on our trip showed no mercy—but the Pro Issues survived these tough conditions better than either Braden or I!

I should mention that one smart thing Nocs has done with their optics is to recess the objective lenses deep inside the tubes. This means that as they hang from your neck, rain won’t land on or “creep around” to the lenses—avoiding a potential constant hassle. One thing I do hope Nocs incorporates into future products is a “faster” focusing knob, requiring fewer revolutions to go from very close to very far focus. This would make it easier to zoom in on fast-moving birds.

Even in the rainiest conditions, my Pro Issues stayed tightly sealed and did not fog—allowing me to fully enjoy marvelous birds such as this Bicolored Antbird (teaser for our next post!).

Of course none of the above matters without good quality optics, and the Pro Issues definitely hold their own against other equipment in a similar $300 price range. Nocs uses BaK-4 prisms, a higher quality prism that ensures even, full-spectrum light transmission. Like other quality companies, Nocs uses coated, scratch-resistant glass. The result? In bright to medium-low light, I got nice crisp, well-lit, full color looks at birds, even from a good distance. Taking 8X42 instead of 10X42 binoculars proved a good choice for in-close rainforest conditions by giving me a wider field of view and more light, and I rarely missed the extra 2X magnification of 10X42s.

As every birder knows, however, things do get tough in very dark, overcast rainforest understory conditions, challenging the abilities of almost any optics. In my equipment testing, finding binoculars that will “see through” the darkest most abysmal conditions—or the most awful gray backlit situations—requires a price jump up into the $1,000 range, not something most birders can afford. (See, for instance, this review and this one). That said, for $299.95 the Pro Issues offer solid, competitive value while boasting some additional advantages . . .

Nocs is committed to operating sustainably and that includes avoiding plastic packaging. Note, I especially like the cloth carrying bags (left, under the binoculars) that come with their equipment. While offering less protection than hardshell cases, the bags are much less bulky, saving precious space when traveling.

In an age when many corporations throw their weight around with little regard to the environment and social justice, Nocs offers a refreshingly positive set of values for the ethically responsible birder. The company is a member of 1% for the Planet, donating 1% of its revenue to supporting environmental organizations. It is also certified as climate neutral and is fully committed to sustainable packaging. In fact, I haven’t found a single piece of plastic packaging on any of the Nocs products I’ve received. The quality of its products also ensures that they will last long into the future, reducing the need for buying—and discarding—cheaply made equipment over and over. If your Nocs product should somehow break or fail, the company offers its “No-Matter-What Lifetime Warranty.”

This Streak-headed Woodcreeper is just one of more than 300 bird species I enjoyed observing in Costa Rica using my Pro Issues.

All of this makes me give the Pro Issues a big thumbs up. If you’re still not convinced, I should mention that the 8X42 Pro Issues come in Ponderosa (green), Oxblood Maroon, and Marianas (blue) colors. That will ensure that in addition to having a great set of binoculars to accompany you on your birding adventures, you will be the most stylish birder anywhere in sight!

Birding Costa Rica—Beginning at the Airport

5 Replies

Some of our most popular posts have focused on exotic travel destinations, and today we kick off our latest series on one of North American birders’ most popular choices: Costa Rica. Braden and I just returned from an exhilarating, intense, nine-day birding adventure to the land of Pura Vida, and over the next couple of months I’ll be posting blogs on our most memorable birding experiences interspersed with our usual entertaining “paella” of reviews, domestic birding, and other fascinating topics. Again, we do not receive compensation for our blogging efforts, so if you wish to support our work, please purchase a few new copies of Birding for Boomers, Warblers & Woodpeckers, First-Time Japan, or any of Sneed’s other books. If you already have copies, why not pick up some for your friends? With that, let’s dive into Costa Rica at—where else—the airport!

Braden and I arrived at Juan Santamaría International Airport at 10 p.m.—just time enough to get to the rental car office before it closed. After collecting our vehicle, we drove to a nearby Airbnb so we could get a fresh start in the morning. Having spent a lot of time in Costa Rica the past couple of years, Braden had organized our entire birding itinerary and even picked this first place to stay—not only because it was convenient to the airport, but because it happened to have a terrific, little-known birding spot just down the street.

Braden and I from the porch of our Airbnb in Alejuela—practically under the flight path for San Jose’s international airport, and loaded with birds!

Braden and I are big fans of birding near airports, and have often found hidden avian treasures where you’d least expect them. Just last spring, on my final morning in Texas, I had a remarkable birding session in the vacant lot behind my hotel next to the airport in San Antonio, Texas. And during his spring Costa Rica trip last year, Braden had discovered a special little place only two blocks from our Airbnb. This year, as soon as dawn crept over Alejuela (where San Jose’s airport is actually located), he and I grabbed our binoculars and cameras and headed out.

Our destination was a large city park with the even larger name of Caminito Magico de la Tranquilidad. Being unfamiliar with the rather poor-looking neighborhood, I admit that I felt a bit nervous about our safety, but my concerns quickly vanished. At the park, people were jogging, biking, doing exercises, visiting over coffee, and walking around as in any park anywhere. The park covered several hectares, mostly devoted to playing fields, but a lot of trees threaded the fields and lined the park’s perimeter, and Braden led the way in guiding us on a full circuit.

Even at dawn, Caminito Magico de la Tranquilidad park was bustling with people—and birds! Note the giant mall rising in the background—a good place to escape the heat and grab a bite, though a much better little soda (cafe) sits only a block from the park entrance.

I had spent two months in Costa Rica in 1994, but tragically, that was before I took an interest in birds. Since Braden and I started birding a dozen years ago, I had been fortunate to bird in Latin America several times—most recently in Colombia con mi amigo, Roger—but it was fair to say that I was a novice at Costa Rican birds. I had been studying, however, and to my delight Caminito Magico park presented a perfect warm up for the week ahead.

Entering the park, a Squirrel Cuckoo immediately flew across a soccer field in front of us. Braden identified Orange-chinned and Crimson-fronted Parakeets loudly squawking overhead, and I was thrilled to see my first ever Hoffman’s Woodpecker land in a nearby tree.

My very first Hoffman’s Woodpecker put me in an ebullient mood as we kicked off our first Costa Rican birding session!

The park was filled with many of the more common birds any visiting birder will quickly get acquainted with. These included five kinds of pigeons and doves, Tropical Kingbirds, Great Kiskadees, Great-tailed Grackles, and Costa Rica’s national bird, Clay-colored Thrushes. Blue-gray Tanagers flew between trees while Blue-and-White Swallows darted for insects overhead.

Baltimore Orioles are common throughout Costa Rica—and never fail to raise a smile for a visiting Norteamericano birder!

As we reached the far perimeter, I was delighted to find that a creek skirted about half of the park’s boundary. Trees grew thickly here, and following the pleasant path, the birds got even more interesting. Braden began pointing out Chestnut-capped, Northern Yellow, and Tennessee Warblers while I focused in on a stunning male Baltimore Oriole in a flowering tree. Braden also detected several kinds of wrens: Southern House Wren, Rufous-and-White Wren, Cabanis’s Wren, and the beautiful bruisers of the bunch, Rufous-backed Wrens.

This would be the only location on our trip where we would see the “giant” Rufous-backed Wren—another reason to bird the San Jose area before heading into Costa Rica’s hinterland.

This being in the heart of Costa Rica’s largest city, I gotta tell you that I had no expectations for the creek itself, especially because it was strewn with an assortment of trash. The birds apparently didn’t care and almost immediately, Braden pointed out one of the birds I had most wanted to see on the trip—Bare-throated Tiger-Heron! I was thrilled, but hardly had time to appreciate it as we spotted a quail-sized coot-like bird skulking the banks—a Gray-cowled Wood-Rail!

For me, seeing a Bare-throated Tiger-Heron and Gray-cowled Wood-Rail (above) were stunning surprises in the heart of Costa Rica’s largest city!

Soon after, Braden pointed out a Northern Waterthrush while I spotted a Green Heron along the opposite bank. This, of course, is one of the magical things about birding the neotropics: how in the midst of all of these amazing new tropical birds, we find many species that are totally familiar to us in North America. It begs the definition of just what a neotropical bird is since in reality, many species we Norteamericanos consider “our birds” are just visiting us for a short time, and can more rightly be considered tropical species. Maybe that’s how this park got the name “Magico”?

Seeing “North American” warblers such as this Northern Waterthrush in the tropics makes you rethink what we consider “our” birds.

Our delightful discoveries were far from over. At the far corner of the park, we met an amateur naturalist who visited this spot almost daily to monitor wildlife, and he generously shared that only minutes before, he had seen one of the San Jose Valley’s most intriguing endemics. We hurried down the trail and only fifty meters later saw them: Cabanis’s Ground-Sparrows.

Cabanis’s Ground-Sparrows are related to White-faced Ground-Sparrows, but live only in the San Jose area—an intriguing case of endemism that would make a great PhD research topic!

These are birds that Braden especially wanted to show me—but didn’t think he could. These handsome little guys live only in central Costa Rica, specifically in the valley occupied by San Jose. While not rare, they often tend to be pretty shy, making them challenging to see. They prefer scrubby, disturbed places like forest edges, coffee plantations, and apparently, city parks with lots of places to hide. Braden and I both began clicking off photos, but mostly we enjoyed watching them, one of dozens of unexpected surprises we would encounter over the next nine days.

As we were winding down our visit with the Cabanis’s Ground-Sparrows, I saw a larger bird swoop past us and land on a nearby branch. “Braden,” I hissed. “Look!” It was a final gift from this amazing city park: a Lesson’s Motmot! Not only that, it struck an incredible, leisurely pose. Motmots, of course, are some of Latin America’s most distinctive tropical birds and always high on a visitor’s to-see list. I was no exception, and felt enormously grateful to see one in our very first hour or two of Costa Rica birding.

Seeing a Lesson’s Motmot in our first birding session left no doubt that we were birding somewhere far different from Montana!

We finished our list with 47 species—almost as many birds as I’d seen in Montana in the first seven weeks of 2026! It was an awesome kick-start to our expedition, and we celebrated by grabbing our first Tico breakfast of rice, beans, eggs, and fruit at a little family diner only a few meters from the park entrance. We couldn’t predict how many highs and lows the next nine days would hold for us, but we were grateful and happy for such a promising start!

Braden has a passionate fondness for Costa Rican food, and after our first birding session we wasted no time in getting him a traditional Tico breakfast just a block from the park entrance!

The NOCS Field Tube 10X32 Monocular (FSB Equipment Review)

2 Replies

I’m excited this week to offer our very first equipment review of a Nocs Provisions product: The Field Tube 10X32 monocular. This is the very first monocular that I’ve ever used, and I was so excited that I tore it out of the packaging and immediately set about field testing it. Before I offer my thoughts, however, I want to say a bit about Nocs.

Everything about this smaller optics company compels me to like them. For one, they take pains to send their products in sustainable packaging—a definite plus for a birder wanting to protect birds and our environment. They are a 1% for the Planet member and a Climate Neutral certified brand. To quote their PR info, “At its core, the company believes that the more we observe and understand how intricate and delicate our planet’s ecosystems are, the more motivated we are to protect them.”

The 8X32 Field Tube shown in Banana Slug (Yellow). This version also comes in Corsican (Blue), Coral (Red), and Desolation (Black). The 10X32s I tested are offered in Ponderosa (Green), Paydirt (Brown), and Oxblood (Maroon). Order by clicking here or on the image above.

Nocs, though, also offers products with super cool designs. The rubber “wave grip” coating of the Field Tube not only offers a great gripping surface, it looks way bitchin’ compared to the standard black exteriors offered by most other manufacturers. Not only that, Nocs products are offered in different colors. Need a pair of binoculars to match your powder blue tux for the Birding Academy Awards? Perhaps something to blend in with your Ferrari while visiting Tuscany? Nocs has got you covered.

But let’s get to the main point, the Field Tube 10X32 monocular itself. First let me say that for birders, this is a “next item” purchase. It’s not intended to replace your binoculars. Rather, it is designed for situations where a slim profile and super light weight are of premium concerns. With a length of only five inches and weight of half a pound—or about a third of traditional binoculars—the Field Tube easily fits into a front pocket and can barely be felt hanging around your neck. This makes it perfect for backpacking, travel, and paddle-boarding. But I can envision other ideal scenarios for this equipment, too. For instance, imagine . . .

The Field Tube is so small and light that you can take it virtually anywhere without noticing it. We call this BIRD PREPARED!

You are in an expensive Tokyo restaurant trying to close a deal with a major Japanese tech company. Suddenly, an Azure-winged Magpie lands in a tree outside the window. You do not want to offend the company president sitting across from you, but . . . as soon as he gets up to use the restroom, you whip out the Field Tube from your front pocket for a delightful look at this long-hoped-for life bird. Or . . .

You’re waiting for your perfect big wave set at Mavericks near Half Moon Bay and an intriguing small black bird lands in the water. Unfortunately, it is too far away to ID with the naked eye. BUT, you just happen to have your Nocs Field Tube stuffed inside the neck of your neoprene wetsuit and, focusing in on the bird, you discover it is a Long-billed Murrelet, just flying in from Siberia! Not only is it a life bird, it allows you to break the ABA Big Year record for surfers, earning you glory, fat promotional contracts, and a sponsorship to bird and surf the world!

You can see where I’m going with this, and I’m sure you can come up with other equally realistic scenarios where you’ll want this item close by.

The Field Tube comes with a handy wrist strap, soft protective carrying bag, and lens cloth—all packed in 100% sustainable recyclable packaging.

A couple of things I especially like about Nocs products is that they come with solid rubber stoppers that snugly pop in over the objective lenses. It’s amazing how even high-end manufacturers have not solved the problem of keeping the objective lens covers firmly in place. I also really like the strap systems for Nocs products. In fact, when you order, I recommend purchasing the woven strap versions as they are more comfortable and, again, look cool.

But back to the Field Tube, it features a fairly close (9-10 feet) minimum focal length and is waterproof down to three feet deep for up to thirty minutes, making it perfect for birders, butterfly watchers, and surfers. As you would expect, Nocs uses fully coated lenses and prisms, and has a lifetime warranty. I found light transmission quite good in these despite the relatively small 32 mm objective lens.

Just for fun, I decided to see if I could get a digiscope photo through my Field Tube. Not bad for my first effort, if I do say so myself. I mean, you can easily see both the Harpy Eagle and Imperial Woodpecker in the photo, right?

At a price of $129.95, you wouldn’t expect perfection from the Field Tube, and I did notice a couple of things that could use improvement. While the focus is quite sharp at close and medium ranges, it gets a bit softer at distance. I’d also like to see fewer turns of the knob required to bring the focus from close to far distance. However, most people will find these minor issues acceptable trade-offs for the incredibly small profile and convenience the Field Tube offers.

Nocs has recently unveiled a monocular upgrade called the Zero Tube which is even smaller and lighter than the Field Tube, and uses a different focusing mechanism. Hopefully, I’ll get to test that one in the future. Next up, though, will be my review of the Nocs Pro Issue 10X42 binoculars, which I am taking to Costa Rica on my trip with Braden next week. My initial impressions of the Pro Issues are extremely positive and I look forward to giving them a full tropical workout. Stay tuned!
