Vortex Viper HD Binoculars (Equipment Review, and/or Texas 2025 Part 2-½)

I hope that you’ve enjoyed our last two posts about my recent Texas birding adventures. Never fear, more Texas posts are coming! Today, however, we’d like to offer up another in our popular new series of equipment reviews. Why? Because my Texas trip gave me a wonderful opportunity to field test a pair of Viper HD 8X42 binoculars from Vortex.

**Vortex Viper HDs offer great quality at a reasonable price.**

If you’re out in the field a lot, you’ll see many birders using the Viper HDs, and for excellent reasons. In hand, the binoculars are sturdy and comfortable to hold, yet lightweight enough to carry around all day without discomfort. Like all Vortex optics, they come with an incredible no-questions-asked, fully transferable, lifetime warranty—something almost priceless for the peace of mind it offers. But the question remains: how do they perform in the field?

**Backlit conditions—especially on water—are one of the true tests of binocular clarity and light transmission. The Viper HDs performed extremely well under these conditions.**

My Texas trip allowed me to test the Vipers in a variety of birding situations. In my last post, I shared my thrilling visit to the Anahuac National Wildlife Refuge (now renamed to the Jocelyn Nungaray NWR), and almost immediately, I was confronted with the daunting task of observing shorebirds and waterfowl under extreme backlit conditions. Anyone who has experienced this knows how difficult it is to discern details of birds when bright glare turns the birds into shadowy figures, and I immediately thought, “Oh man, I don’t know if I’ll even be able to start identifying some of these critters.” To my surprise, the Viper HDs cut right through the glare. One small backlit shorebird particularly caught my attention, and I was sure I wouldn’t be able to see enough details to ID it. Focusing in with the Vipers, the bird’s features just popped—including its yellow legs, which allowed me to identify it as a Least Sandpiper.

**The Viper HD’s excellent light transmission allowed me to ID this Least Sandpiper and other shorebirds under badly backlit conditions.**

A couple of days later, I arrived at an exciting new (to me) location called Lafitte’s Cove on Galveston Island. This cool little nature reserve sits in the middle of an upscale housing development and features ponds, walking paths, and wooded areas. My main goal was to try to find migrating warblers and, thanks to the advice of some local birders, I staked out a drip in the wooded area that provides fresh drinking water for birds. Soon, I saw two shapes flitting around in deep shadow behind the drip. One leaped out into the sunlight—a Tennessee Warbler. The other bird proved much more cagy. Even as it stayed in the shadows, though, the Vipers gave me the sharp, full-color details that allowed me to confirm that it was a Nashville Warbler—a real surprise since I had never seen one before in the eastern US!

**Lafitte’s Cove on Galveston Island was a wonderful addition to my list of spring migration birding hotspots—and helped me test the Viper HDs under dark, shady conditions.**

As always, prospective buyers will ask, “Are the Vipers worth what they cost?” On the Vortex website, the 8X42s and 10X42s list for $719.99 and $729.99 respectively—not an inconsiderable sum. However, in “real life” the binoculars can be purchased for under $500, putting them in range of a doable investment for many birders who are ready to get serious, but can’t or don’t want to shell out thousands of dollars. Even for $500, though, you expect binoculars to be durable and weather-resistant, and the Vipers deliver on that count. Other great features include:

* a diopter ring that allows independent focus adjustment for each eye

* long (18 mm), rubberized eye-relief tubes designed to press eyeglasses against them without damage

* a close (six-foot) minimum focal distance

**A comfortable grip and long, comfortable eye-relief tubes are just two great selling points for the Viper HDs.**

As I have tried various brands and models of binoculars, though, for me it has become mainly about clarity. In other words, how well do the binoculars transmit light and how sharp is the image they deliver? As noted above, the Vipers deliver excellent performance in this regard. During my week in Texas, I never found a situation in which I had difficulty picking out colors and other details. That’s because, for the extra price investment, Vipers offer two advantages over many cheaper binoculars:

* extra low-dispersion glass that reduces chromatic aberrations and improves light transmission, even under difficult conditions such as those I experienced above

* high-quality coatings on both the glass and internal prisms which improve light transmission, creating a sharper, clearer image.

I have not yet found the perfect binoculars—if they indeed exist—and one thing I wasn’t crazy about is that I had to turn the focus knob quite a bit to bring the Vipers into focus between near and far situations. Presumably, this allows users to obtain a more precise focus on an object, but I found it wasted a bit of time and effort. This is a personal preference, however, and I’m guessing that most users will be just fine with this.

A final note: frequent FSB contributor Roger Kohn and his wife both happen to use Vortex Vipers. “We are very happy with them,” he says. “Really good quality glass, clear images. Feels good in the hands.”

Conclusion: the Vortex Viper HDs are an outstanding pair of binoculars for those ready to make a mid-range investment into the world’s greatest hobby. Sturdy construction, a light weight, and excellent light transmission make them suitable for almost every situation, and will provide years of satisfaction to the vast majority of birders.

Peveto Woods, Louisiana: Spring Migration Hotspot

FatherSonBirding is a labor of love for both Braden and me, and our goal is to entertain and educate, and to promote bird conservation. If you’d like to support our work, please consider buying one or more of Sneed’s books and make a donation to one of the bird-related groups mentioned below. Thank you!

There’s a good reason the blog has been quiet the past couple of weeks. Braden is finishing up his honor’s project before graduating (gasp!) from the University of Maine while I jumped on a chance to head to Texas for the sixth time since Braden and I began birding. The trip arose from an invitation to talk about my book Birding for Boomers at the Mountains and Plains Independent Booksellers Association spring conference in San Antonio. Happily, the event took place during spring migration, so I of course booked three extra nights before and three extra nights after the conference to see some birds!

As soon as I picked up my rental car in San Antonio, I high-tailed it the four hours to Winnie, Texas on the coast just east of Houston. Why Winnie? Because it provides great access to several well-known stopover places for migrating songbirds and offers a chance to soak up a variety of coastal and aquatic species as well. For this trip, though, I was determined to explore some new birding areas, and my first morning I got up before dawn and headed to my first destination, Peveto Woods Sanctuary, just across the border in Louisiana.

A bonus to driving to Peveto Woods is that once you cross the bridge into Louisiana at Sabine Pass, you can find a wonderful little shorebird area, especially if it happens to be low tide. And by the way, I don’t think I’ll ever get tired of posting Black-necked Stilts. So sue me already!

**Peveto Woods offers delightful paths through trees, any one of which could be hiding a migrating songbird!**

Peveto Woods is owned and operated by the Baton Rouge Audubon Society and like Sabine Woods run by the Texas Ornithological Society and the more famous High Island sanctuaries operated by Houston Audubon, Peveto consists of a patch of forest right along the shore. As soon as I pulled up, I knew I was going to like it. Trails headed off in all directions, crisscrossing forty acres of mostly oak-dominated woodlands. I saw two friendly-looking guys, Scott Delaney and Paul Wallace, who looked like they knew their way around and asked the best way to explore. It turns out, they had been volunteering their time here for many years and suggested I make my way to the east fence line and work my way back. They also explained that the land where the woods sat was called a chenier, a place where wave actions had piled sand and shells up higher than the surrounding area, allowing trees to grow. Hurricanes still occasionally obliterated the place, but the vegetation recovered quickly.

**Hey, I’m gettin’ pretty good at these selfies–this one with my new birding friends, Paul (center) and Scott.**

Unfortunately, I quickly learned that the main birds I had hoped to see—warblers—had not yet arrived in significant numbers. I was about a week early for many species and, for now, northerly winds had kept others grounded in the Yucatan. Only one hundred yards down the trail, however, I encountered a nice little mixed flock of other species. Sound ID picked up a White-eyed Vireo, and I quickly saw a Warbling Vireo along with at least four Red-eyed Vireos. Joining them were several Orchard Orioles, a couple of Yellow-rumped Warblers, and an Orange-crowned Warbler. Most were flitting about high in the trees, making photography difficult, but my heart warmed at seeing them.

**Although the more exotic warblers had yet to reach the Gulf coast, this (Myrtle) Yellow-rumped Warbler tried to hold down the fort till they arrived!**

One awesome thing about Peveto is that you can walk right out to the beach and here I saw the trip’s first Black-bellied Plover, along with a couple of Royal Terns and Willets.

**For those aware of my love of Black-bellied Plovers, you can imagine how delighted I was to find the first one of the trip on my very first outing.**

Returning to the woods, I kept strolling, finding migrating Gray Catbirds and pre-migration White-crowned Sparrows. A couple of Anhingas flew over, and then Sound ID picked up what would be the star of my visit: a Yellow-throated Vireo.

**I just fell in love with this Yellow-throated Vireo. In fact, YTVIs are one of my new favorite birds, and I would see or hear them twice more on the trip.**

I had seen YTVIs before, but so early in my birding career that they had gotten lost in the steepness of my learning curve. Now, a bird in glorious yellow, white, and gray plumage perched right above me. I shot some quick photos, and then just stood and admired this incredible creature. Like most other vireo species, this one had migrated from Central or South America, completing the eighteen-hour or so flight directly across the Gulf of Mexico.

**It seemed like years since I’d seen Indigo Buntings—and then, only females or juveniles. That made it all the more sweet to find these two “Sharp-dressed Men.”**

It did make me wonder, though, why the vireos had made it “on time” but most of the warblers had not. “Are vireos stronger fliers?” I wondered. Or had they just timed things better? Either way, I was delighted to see them and get to know them better. And that’s birding for you. Even if the birds don’t always meet your own timetable, they always present a fascinating learning opportunity or two—or, as today, a chance to embrace and enjoy a new group of birds. I rounded off my morning by finding a couple of gorgeous Indigo Buntings on the brushier end of the preserve. I exchanged email addresses with my new friends Scott and Paul, and invited them to look me up when they came to Montana. I suspected, though, that I might make it back to Peveto Woods long before they got to Montana!

Note: As I post this, the warblers are definitely arriving at Peveto Woods. If you live nearby, what are you waiting for?

Roger and I could easily write another ten or twelve posts about our recent birding adventures to Colombia, but I thought it would be fun to pack a lot of our experiences into a video featuring our main destination down there, the Araucana Lodge. The video not only introduces you to the joys of lodge birding, but features some of the famous birds and birding opportunities to be had in the mountains above Cali. Since large files don’t always work well on this blog host, we embed a YouTube link below. Let us know what you think—and enjoy the show!

The Shorebirds of North America (Book Review)

2 Replies

With spring shorebird migration coming on, we take a break from our Colombian birding series to review a new book that will help prepare you for the exciting, sometimes daunting task of identifying and enjoying some of the world’s most spectacular long-distance migrants. Bird—and read—on!

Legions of FatherSonBirding readers have probably noticed that Braden and I have increasingly become interested—nay, obsessed—by shorebirds over the years. See, for example, our posts

Montana Shorebird Surprise

Abbotts Lagoon, Point Reyes National Seashore (or Chasing Migrants, Part II)

Our fascination may seem odd given that Montana is hardly the world’s epicenter of shorebird activity. Then again, their very rarity here renders them all the more alluring to find and learn about. A natural birding progression also is at work. When beginning one’s birding journey, we birders naturally focus on common, familiar species. As confidence, curiosity, and ambition grow, so does the desire to learn about and identify more difficult groups of birds. When we first began birding, Braden and I focused on woodpeckers, thrushes, waterfowl, waders, owls, and other easier-to-identify species. Over the years, we have plunged into increasingly challenging groups including warblers, sparrows, flycatchers (Braden), gulls, and perhaps more than anything, “shorbs.”

**A flock of Western Sandpipers at Point Reyes during my September visit to California with Scott Callow.**

When out scanning beaches or shallow lakes, the most common phrase Braden repeats to me is “Shorebirds are tough.” This usually happens when I am whining about the difficulty in distinguishing between off-season Least and Semipalmated Sandpipers, or White-rumped and Baird’s Sandpipers—especially at a distance. But many shorbs are relatively easy to identify, and over the years both Braden and I have come to appreciate—nay, savor—the entire breadth of these fascinating, superbly adapted critters. Imagine my joy, then, when a brand new, beautifully photographed book about shorebirds arrived on my doorstep: Pete Dunne’s and Kevin T. Karlson’s The Shorebirds of North America: A Natural History and Photographic Celebration (Princeton University Press, 2024).

*The Shorebirds of North America* by Pete Dunne and Kevin T. Karlson (Princeton University Press, 2024)

To say that The Shorebirds of North America is ambitious would be like calling the 18,000-mile round-trip migration of a Red Knot “neat” instead of “epic” or “mind-blowing.” This terrific addition to birding literature not only gives a wonderful overview of the lives of shorebirds, it provides specific accounts of all the shorebirds likely to interest you. That makes this book a wonderful, highly readable reference for both beginning and advanced birders.

The bulk of the book consists of species accounts of 52 kinds of shorebirds known to breed in North America and my guess is that you, like me, will skip directly to species that happen to interest you at the present time. This is a great approach. One of the first shorebirds I looked up was Black-bellied Plover, a bird I have become more and more enthralled with the past several years. As I started to read, my understanding of this handsome creature immediately swelled. I didn’t realize, for instance, that it is one of the world’s most widely distributed shorebirds, or that it is called Grey Plover outside of North America. What really tickled me was learning how fearlessly aggressive these birds can be:

“On the high Arctic tundra breeding grounds,” the authors write, “this sturdy plover is a fierce protector of its large nest area, and it strikes fear into aerial predators as large as gulls and jaegers. Woe to any flying predator if it hears the whistled alarm call of Black-bellied Plover as it flies swift and low across the tundra before rising to spear the intruder in the belly with its strong bill . . .”

The 4-letter breeding code for Black-bellied Plovers is BBPL. After reading the entry for the bird in *The Shorebirds of North America*, however, I realized that BBPL could easily stand for “Bad-ass-bellied Plover”.

Who knew that one of my favorite birds is such a bad-ass? Similarly delightful “reveals” can be found in each account, many of them based on the authors’ own personal and scientific experiences with the birds.

Far from just being pretty to look at, the book’s incredible photos add real understanding of each species by showing them in a variety of plumages and situations. I enjoyed just quizzing myself on the photos as I made my way through the book, testing and expanding my knowledge as I went. I cannot imagine the effort Kevin T. Karlson and the book’s other photographers invested in creating what may be the world’s finest collection of shorebird photos.

Another thing I learned from *The Shorebirds of North America* is that the bills of oystercatchers are laterally compressed. You can’t tell this from the typical side view, but this compression turns the bills into excellent chisels for prying limpets, snails, and chitons off of rocks.

As delightful as the species accounts are, I strongly urge readers to read the entire first section straight through. In this section, the authors provide excellent perspective on all shorebirds including their remarkable adaptations, habits, diversity, and evolution. Fascinating anecdotes abound, such as the story of B-95, a banded Red Knot known to have traveled more than 400,000 miles during his 21-year lifetime. The authors don’t bother to hide their admiration for these birds:

“Challenged to design the perfect bird, we would without hesitancy delve into ranks of shorebirds and reach down to the Scolopacidae (sandpipers), the largest of the roughly six or seven family groups in the shorebird order Charadriiformes.”

Another fascinating fact I picked up from *The Shorebirds of North America* is that the curved bills of Long-billed Curlews are almost perfectly designed to snatch fiddler crabs from their long, curved burrows. They’re also great for picking off grasshoppers without alerting them to their imminent doom.

I could keep singing this book’s praises, but really, if you have even the tiniest, nascent interest in shorebirds, you should order a copy yourself. Given its length and full-color format, I expected the book to sell for at least fifty or sixty bucks, but at the time of this posting it can be had for a bargain $35. That puts it within reach of most people—and makes it an investment in your birding future you won’t regret.

One-Sentence Summary: A highly-readable, indispensable resource for both beginning and advanced shorebird enthusiasts.

Overall Rating (on a scale of cool birds): Piping Plover (highest)

You can order The Shorebirds of North America from your local independent bookstore, or directly from Princeton University Press. Please tell them we sent you!

Layover Birding in Bogota, Colombia

4 Replies

“Call me asap,” Roger’s text read. A few minutes later, I dialed his number. “What’s up?”

The answer: a chance of a lifetime.

As faithful FSB readers know, Roger is a longtime friend of mine from UC Berkeley, and a guest contributor to FatherSonBirding. More than six months ago Roger and his wife, Claudia, began planning a dream birding trip to the world’s epicenter of awesome birding—the country of Colombia. How awesome is Colombia? Well, during the Global Big Day of birding each year, Colombia regularly kicks butt on all challengers. In 2024, its birders recorded an astounding 1558 species in a single 24-hour period—more than twice the number of the US despite submitting only about 15% of the number of checklists. It is widely considered to have the highest biodiversity per square meter of any country on earth.

Sadly, Colombia has a long history of violence that has made it mostly off-limits to birders for decades. That began to change in 2016, when a peace agreement was signed between the government and FARC, the military wing of the Colombian Communist Party. Violence still racks some parts of the country, but that has not prevented a growing number of birders from seizing the chance to visit one of the world’s most spectacular ecological regions. About six months ago, Roger decided to join those growing ranks. He and Claudia mapped out a two-week trip that would include a feast of birding opportunities. However, as the great oracle of our time, Neil Young, sang, “The devil fools with the best-laid plans.” Two weeks before their trip, Claudia was forced to cancel, and Roger asked if I wanted to fill her slot. With a quick nod from Amy and the urging of Tessa, it took me about two minutes to decide.

The plan was to meet up in the Andean city of Pereira to begin our birding adventure (of which I’ll write much more later). Roger planned to fly from his home in Bend, Oregon to Miami and spend the night; then fly to Pereira via Panama City the following day. Being a Delta Airlines loyalist, I left a day earlier, spent the night in Atlanta and then flew to Bogota for a night. This excited me greatly because it would give me a morning to myself before catching a flight to Pereira to meet Roger. Gee, what oh what might I do with that morning?

Not by accident, I booked a room in the Hotel Capital, strategically located a short taxi ride to two major birding possibilities. Rising early, I wolfed down a granola bar for breakfast and then caught a cab to Parque Metropolitano Simón Bolívar, one of the world’s largest urban parks. In my atrocious Spanish, I told the cab driver of my interest in birds and he dropped me off at the SW corner of the park near a large central lake. I had worried a bit about carrying my camera and binoculars in this unfamiliar city, but my hotel concierge had assured me the park would be safe. Sure enough, I was relieved to see a steady stream of joggers, dog walkers, and cyclists taking advantage of a beautiful sunny morning. But what of the birds?

As I walked toward the lake, I saw plenty of Great Thrushes and Eared Doves, and Sound ID picked up the songs of Rufous-collared Sparrows, a bird Braden and I had become friends with on our family trip to Ecuador and Peru in 2017.

Like a birder magnet, however, the lake drew me forward. When approaching a large body of water like this, I always look for legions of water birds to be gracing the water, and in Japan and last year’s trip to Barcelona, that had indeed been the case. Not today. Evidently, ducks just aren’t as big a deal in the tropics as in temperate zones. I did spot what looked like a domestic hybrid duck of some sort, accompanied by a much smaller bird, and I focused in on the latter for the day’s first surprise—a Pied-billed Grebe! “I didn’t know they lived this far south,” I thought. Indeed, I later learned that in the Americas, Pied-billed Grebes have the largest distribution of any grebe, stretching from mid-Canada almost to the tip of South America.

**Pied-billed Grebes have the widest distribution of any American grebes.**

A hundred meters farther, I caught movement in bushes and discovered one of the real prizes of my outing—a mixed flock of warblers! And not just any warblers, but three species that breed in the eastern US. One revealed a brilliant splash of orange on its face. Can you guess which one it was? That’s right—Blackburnian Warbler! It was accompanied by several Tennessee Warblers and my first look at an actual Rufous-collared Sparrow.

As I followed the flock around, I got an even bigger surprise—a bonafide American Redstart. “Wow!” I said out loud, trying to get a photo of one of everyone’s favorite warblers.

From the main “parky park,” I crossed a pedestrian bridge over jammed up morning traffic and entered a sprawling sports complex.

**You’ll be relieved to learn that Colombia has the same kinds of traffic problems as we do!**

Soccer players were warming up, track and field athletes ran around a track, and tennis players smacked balls back and forth. Next to the walking path, a pair of familiar-looking black-and-white birds hopped up onto a sign. It didn’t take me long to figure out they were Tropical Mockingbirds—the only ones I would see on the trip! Then, a familiar, largish bird flew noisily by and disappeared over the wall into a stadium. Here, Braden’s and my travels to Israel paid off. Southern Lapwing! my mind immediately shouted. My real destination, though, lay just ahead.

**Look familiar? It didn’t take me long to figure out that this handsome fellow was a Tropical Mockingbird.**

I paid two bucks to enter the Jardin Botanico de Bogota—which, like the sporting complex, was technically part of the Simón Bolívar Park—and asked a greeter where I might find birds. Then, I set off to explore. My first find? Gorgeous Purple Gallinules. Hummingbirds also flew by, but knowing just how many hummers fill South America, I wasn’t psychologically ready to tackle those just yet.

**It’s hard not to be impressed with the technicolor plumage of Purple Gallinules.**

Continuing on alongside a wooded area, I spotted a bright red shape about twenty feet high on a branch—my first South American Summer Tanager! I saw another traveler staring up into the trees and walked over to introduce myself. “My name is Edwin,” he told me, along with the fact that he was from the Netherlands. “Are you seeing anything?” I asked him. “Yes, but I don’t know what they are,” he confided. I got my eyes on fast-moving, small shapes and recognized another Blackburnian Warbler, along with what I think were more Tennessee Warblers. I told Edwin what I was seeing.

“Hey, did you see the Summer Tanager?” I asked, and his eyes widened. “No!” So I led him back to where I’d spotted it, relieved to finding it still perched, evidently being well-paid by the botanical gardens staff to stay in place.

**I had hoped to see some of our northern birds in their southern wintering grounds, but didn’t expect to see a Summer Tanager in downtown Bogota!**

By this time, I was only up to about twenty species, which seemed like a rather poor showing for a morning in a brand new tropical country, even if I was in a major city. Only one of those species, Shiny Cowbird, was a lifer. Even worse, it was about time for me to flag down a cab and make my way back to the hotel so that I could shower, pack, and get to the airport for my flight to Pereira. Before leaving the gardens, however, I decided to make one last stop where I had seen the gallinules. Suddenly, I detected a small bird flitting among some flowers, and my pulse picked up. I didn’t know what it was, but got some decent ID shots of it. As I zoomed in on one of my photos, a smile spread across my face. It was a flowerpiercer—the first I had ever knowingly seen! Later, I consulted with Braden and we agreed that it was a beautiful little species called a Rusty Flowerpiercer.

**I was thrilled to find this Rusty Flowerpiercer, the first flowerpiercer I’d ever identified on my own.**

It was a great way to finish off a fun morning of layover birding in a new country. It also laid the groundwork for what would promise to be an adventurous—sometimes too adventurous—next couple of weeks.
