Our 2024 Recap: Spain, Costa Rica, Japan (again!) and More

2024 has been a record-breaking year for FatherSonBirding—and in more ways than one. Let’s start with the stats. Number of views to our site increased by almost 50% over last year to almost 14,000, while the number of visitors increased 65% to about 10,000. Much of what is driving these increases is interest in our posts about foreign birding destinations including Japan, Costa Rica, and Spain. In fact, viewers from 104 different countries visited our site this past year. Top views from countries other than the US were:

Japan: 445

United Kingdom: 384

Canada: 352

Australia: 244

Singapore: 208

Despite being published in 2023, our birding posts from Japan dominated views this year, especially with FSB visitors from foreign countries! Here, Tessa and I visit The Great Buddha, or Daibutsu, of Kamakura—apparently the second largest Buddha in Japan, one that harkens back to about 1252.

So which of our posts received the most views? Here is our Top 10 for 2024 (plus/minus 10 views each, given the quirks of the statistics-accumulating program):

1. Birding Japan, Kyoto: 811

2. Birding Japan, Tokyo Part I: 573

3. Birding San Antonio’s Riverwalk, Are You Nuts?: 568

4. Birding Barcelona Part I, The Urban Core: 463

5. Birding Japan, Kanazawa: 332

6. Birding Glacier National Park in the “Hot Dry Winter” of 2024: 289

7. Getting Serious About State Birds: 284

8. Braden’s Costa Rica Report #3, El Copal: 249

9. Turning Useless Lawn into Vital Habitat: 196

10. Monotypic Birds, Evolution’s Survivors: 195

A couple of things become evident from this list. One is that many birders are travelers. Even though they are from 2023, our Kyoto and Tokyo posts (links above) continue to get hits every day, often from people outside the United States. Despite this stiff competition, our post about San Antonio’s Riverwalk still wears the crown of our all-time most viewed site. It doesn’t take a genius to figure out that all of this is because of how many birders are out traveling the world!

If you remember this Red-shouldered Hawk, you’ve been reading FSB almost from the beginning! Our post on birding San Antonio’s River Walk still holds the title of our most viewed post ever, with almost 2,000 views.

Our top posts, though, also reveal that readers of FSB have a major interest in environmental issues, as is revealed by our Glacier National Park post and our post “Turning Useless Lawn into Vital Habitat.” We take great satisfaction in that because one of the main reasons we write FSB is to help increase awareness of the environmental plight of our planet—and birds in particular—and what we can all do to improve the situation. Planting native plants in our yards is an especially simple, effective approach to increasing vital habitat that birds and their prey depend on. We’re happy that so many people took time to read our post on this topic.

Enthusiasm for our post on the dry hot winter of 2024 revealed a strong interest in the environment among FSB readers. Good job, readers!

But the year is only a little about statistics. Braden and I both had wonderful birding adventures in 2024. Thanks to his semester abroad in Costa Rica, Braden saw a remarkable 736 species of birds in 2024. More important, he got dozens of other young people into birding by starting the wildly successful UMaine Birding Club. The club did all kinds of fun activities, from leading dozens of birding outings to hosting movie nights and launching a project to reduce bird strikes on the UMaine campus building windows. Braden and I also finally got to take the eastern Montana birding safari of our dreams, spending two weeks exploring corners of the state we’d never before visited.

Braden’s adventure-packed semester in Costa Rica led him to see a remarkable 736 species of birds for 2024.

I had my own birding adventures including my wife’s and my trip to Barcelona last February, where I picked up a dozen species for my life list and had a whole lot of fun with Amy. I had two great trips to California: one to show my youngest, Tessa, a couple of potential colleges for next year; the second a great Bay Area trip to visit family and friends, including four fab days of birding with my childhood buddy, Scott. Work travel gave me additional opportunities to bird in Oregon, Washington, and throughout Montana. The highlight of the end of my year was getting to bird Cape Cod with Braden during Thanksgiving Week. I am also elated that my newest book, Birding for Boomers, is off to such a great start, reaching #8 the Pacific Northwest Booksellers Association bestseller’s list for nonfiction paperback books!

Thanks to the year’s second trip to California, I got to spend more time than usual with friends—and coastal birds such as this Black Turnstone.

As usual, Braden and I have only vague ideas where 2025 will take us and what we will be moved to write about. A few destinations in the mix: Indonesia, Vancouver Island, Texas. Whatever adventures we have and end up writing about, we deeply appreciate all of you for checking in and taking an interest in the coolest group of critters on earth. We also appreciate you supporting our work by buying our books and sharing FSB with your friends, family, and colleagues.

Until next year, Happy New Year, and may 2025 bring you joy, satisfaction, closer connections and, of course, a whole lotta birds!

Sneed & Braden

In Montana, Some Real October Surprises

For birders, October is an odd month—especially in Montana. Our resident birds have left. Winter residents are just arriving. Most migrating birds have passed through the state—but not quite all. The month poses a special dilemma for those trying to set any kind of Big Year milestone, because time for new birds is running out. This year, for instance, I have found myself tantalizingly close to making 2024 my second best Montana birding year ever. 2020 was Braden’s and my best year, when we put a ton of effort into it, and I recorded 266 species on my list (see our post “2020 Wraps, 2021 Underway”). Last year, thanks in part to an Eastern Montana trip with my pal Scott, I notched my second best year with 253 species. As October wound down this year, however, I found myself with 247 species—seemingly within striking distance of breaking that 253 mark. Or was it?

The Fort Missoula gravel quarry delivered our first American Tree Sparrows of the season—a bird that, unbeknownst to me, I had failed to see earlier in the year! This, dear readers, is also where Braden and I got our lifer ATSPs years ago.

A mere seven species might seem like an easy task with three months to go in the year, but that small number is deceiving. As mentioned above, very few new birds arrive this time of year. As for winter arrivals, most birders (myself included) already saw those in January and February. Bottom Line: By October, birders hoping to set a mark need to track down some rarities.

Braden and I have chased plenty of rarities in the past, but I am more reluctant to do so these days. The main reason? Unless I really, really want to see a particular bird, I can’t justify burning up gasoline just to notch another species on my list—especially to break a rather arbitrary record. After all, climate change—powered in large part by burning fossil fuels—is one of the major threats to birds, not to mention to all other species, and my desire to make 2024 my second best year doesn’t rate as a worthy enough goal to place the planet in even greater peril. With Braden gone, chasing rarities also isn’t as much fun.

Still, last week, with the end of the month in sight, I felt like I could use a good birding session to take advantage of our last warm weather and improve my mental health, made particularly jittery by the craziness of the upcoming elections. And then, out of the blue, I got a text from Nick Ramsey: “Hey! Are you in Missoula? And any shot you want to go birding tomorrow?” I didn’t hesitate. “Yes and yes!” I shot back.

With only hours to spend in Missoula, Nick picked me up for a quick trip to the Fort Missoula gravel quarry and Lee Metcalf NWR, showed above.

Nick, it turns out, had a brief layover in Missoula between a summer field job in Alaska and guiding gigs in Louisiana. Regular readers of FatherSonBirding (or of my new book Birding for Boomers) will recognize Nick both as a member of our extended family, and as our most important mentor when Braden and I first started to bird. We’ve had countless birding adventures together including our first expedition to eastern Montana and Braden’s and Nick’s epic Florida birding trip in 2022. I was thrilled that Nick, who recently graduated from LSU, reached out to me—especially because he had only hours to spare before hitting the road for a 30-hour drive to Louisiana. I asked him what he’d like to do and he suggested visiting the Fort Missoula gravel quarry and Lee Metcalf National Wildlife Refuge. That sounded great to me, and just by coincidence, a Northern Parula had just been sighted at Lee Metcalf.

Decidedly eastern birds, Northern Parulas are almost unheard of in Western Montana. Although chances were low that it would still be there when Nick and I got there the following day, I couldn’t help thinking this could move me closer to tying my “second place” record of 253. For his part, Nick especially wanted to see a Swamp Sparrow, another uncommon bird for Montana. I figured we had almost no hope of finding one of those, but if anyone could, it was Nick.

Nick picked me up at eight the next morning, in the company of his adorable diminutive companion, a chihuahua mix named Dixie, who decided that my lap would be her domain for the rest of the day. Our first stop? The gravel quarry. Nick hoped for a Swamp Sparrow here and we both thought it might be a good chance to see scoters, Long-tailed Ducks, or other laggards passing through the area. Unfortunately, a guy flying a drone was most likely scaring off any interesting water birds. Still, we had a nice sparrow session, finding a ton ‘o Song Sparrows, along with White-crowned Sparrows, and the season’s first American Tree Sparrows—which, I didn’t realize I had failed to find earlier in the year! By the time we headed back to the car, the drone flier also had departed, giving us a look at a few Hooded Mergansers. “Hey, there’s also a Horned Grebe!” I told Nick. That was a nice surprise since I’d managed to miss them in Montana the entire year. Click. With the American Tree Sparrows and Horned Grebe, my Montana Year List had leaped from 247 to 249!

I had given up on Horned Grebes for my 2024 Montana list when this one showed itself at the Fort Missoula gravel quarry.

Continuing on to Lee Metcalf, Dixie keeping me warm, Nick and I caught up on the rest of our lives. This, I realized, was the first time Nick and I had ever birded together without Braden along, and though we both missed him, it was a great chance to share our adventures and discuss future birding dreams, plans, and possibilities. In no time, Nick was pulling into the Lee Metcalf visitor’s center parking lot. Several birders had arrived before us, but none seemed aware of the Northern Parula sighting the previous day. The bird had supposedly been seen in the elm trees next to the closest pond, but as we headed over there, what first caught our attention were two shorebirds pumping for food in the mud.

A pair of Long-billed Dowitchers presented our first surprise at Lee Metcalf. More surprises would follow!

“Are those Long-billed Dowitchers?” I asked Nick. “What are they doing here?” So late in the season, they surprised both of us and immediately made our trip down here worthwhile. While we were studying them, however, Nick’s sharp ears caught something else and he began walking over toward the south edge of the pond. I thought he had heard the Northern Parula, but when I caught up, I found him studying the cattails below us. “I thought I might have heard a Swamp Sparrow,” he explained. Then we saw movement. “There!”

Nick’s Montana lifer Swamp Sparrow was too quick for me to catch in full sunlight, but did pause briefly behind this fence.

Several other birders joined us and it took several minutes for us to get clean looks at the bird. “Furtive” is a good word to describe Swamp Sparrows as they like to stay hidden in reeds along the water’s edge, but finally, the bird gave us full, if brief, views. I was astounded. While only about fifty records exist for Montana, Nick explained that the birds definitely move through the state every year, and Birds of Montana lists several cases where the birds have overwintered. I’d only ever seen one in Montana—in the Shiloh recreation area in Billings—so for me, this was a big deal. Click. 250.

As we moved slowly, following the sparrow to a small brush pile, Nick almost casually said, “The parula’s right behind us.”

What?

It being fall, I expected that if we saw the Northern Parula, it would be a drab specimen. The gorgeous bird, however, delivered a real October surprise.

I spun around and, sure enough, spotted a spectacular yellow-and-bluish-gray warbler plucking insects from leaves in a deciduous bush not twenty feet from us. Nick called to other nearby birders, and they joined us for one of the most leisurely looks at a rare migrant ever. Much like the Black-throated Blue Warbler that appeared in Lolo last year, this bird seemed little bothered by people. We all hung back about thirty feet, trying to fill up our cameras’ memory cards while the bird fattened up on whatever it could find. Just to mix things up, it flew over to an elm tree for a while, before heading back to the bush. After a hike out to the more distant ponds (still no scoters), Nick and I hit the road back to Missoula, making only a quick nearby stop to get Nick a look at California Quail for the year. In a single outing, and at a most improbably time of year, my year list had advanced to 251 species, making me wonder if I could somehow nab three more species through December. Even better, I had enjoyed a wonderful day of birding and companionship with one of the best rare migrants possible, our friend Nick.

Two happy birders following an improbable day of October rarities.

Our Favorite Bird Books for the Holidays

In our last post, we detailed where to buy bird-related books. For our 200th post (gasp), we’d like to share some of our favorite bird books. We are by no means attempting to be comprehensive and we apologize to the many fine authors and books we didn’t have space to include. When it comes to holiday shopping especially, however, we realize that “less is more” so we’ve limited ourselves to the books that first soar to mind. Note that we haven’t gone crazy on the hyper-links here, but recommend just calling your local indie bookstore and placing an order (see our last post). Any of these books can also be ordered from Buteo Books or from a certain not-to-be-named e-commerce giant. Please feel free to share this post with friends and others in desperate need of holiday gift ideas!

Field Guides

There are so many field guides available that your head will spin considering them. Braden and I have enjoyed field guides by Peterson, National Geographic, Kenn Kaufman, and many other sources. The one we return to again and again, however, is The Sibley Guide to Birds, Second Edition. While many other guides seem cramped or present information in a difficult-to-use format, Sibley strikes the right balance with generous, uncluttered illustrations and to-the-point identification information and range maps. If you’re going to buy one guide for the US and Canada, this is the one. Note that if you need field guides for specific countries or regions, you often won’t have a great deal to choose from. Our first stop is usually Princeton University Press, which seems to have field guides for many of the world’s regions (see our last post).

How To” Guides for Beginners

I swear, I wasn’t going to include my own book near the front here, but it logically follows field guides. Especially when it comes to buying a gift for the beginning birder, you can’t beat Birding for Boomers—And Everyone Else Brave Enough to Embrace the World’s Most Rewarding and Frustrating Activity. Here’s a recent review from Foreward Reviews: “Because the book is aimed at new birders, it includes advice about what kinds of binoculars to consider, what clothing and equipment to use, the value of a good field guidebook, and useful online resources. Its guidance is casual, often relayed with light humor and embellished by personal anecdotes. Challenges specific to boomers factor into its advice on birding with hearing, eyesight, and mobility challenges, and into its considerations for those on fixed incomes. It also makes important points about safety for nonwhite and LGBTQ+ birders. With its ranging approach and easy-to-follow advice, Birding for Boomers is a handy guide for all those—boomer or otherwise—who are looking to pick up an ornithological hobby.Click here to order!

Birding Road Trip Books

We’re going to stick with two classics here. The first is Wild America: The Legendary Story of Two Great Naturalists on the Road by Roger Tory Peterson and James Fisher. This really is required—and enjoyable—reading for those working on a life list or doing a Big Year, or anyone wanting to educate herself on the history of birding in the United States. Our second choice is Kenn Kaufman’s irresistible Kingbird Highway: The Biggest Year in the Life of an Extreme Birder. This was one of the first birding books Braden and I read and it is still one of our favorites, recounting the passions and pursuits of someone who just couldn’t help but chase and learn about birds. If you need to add a third title to this list, we wouldn’t complain if you picked up Warblers & Woodpeckers: A Father-Son Big Year of Birding!

Natural History and Science

This category could fill several blogs, but we’ll keep it brief except to say that you must read all of the books below—and they all make great gifts for anyone remotely interested in nature.

Where Song Began: Australia’s Birds and How They Changed the World by Tim Low: highly entertaining, it will change the way you think about birds.

A Most Remarkable Creature: The Hidden life and Epic Journey of the World’s Smartest Birds of Prey by Jonathan Meiburg: a fascinating account of one of our favorite groups of birds, caracaras.

Far From Land: The Mysterious Lives of Seabirds by Michael Brooke: a wonderful account of birds most of us want to spend more time with—but, sadly, never will.

Hard to Categorize—But Read Anyway

The Ravenmaster: My Life with the Ravens at the Tower of London by Christopher Skaife. The title says it all, but doesn’t come close to reflecting just how entertaining and fascinating this book is!

Imperial Dreams: Tracking the Imperial Woodpecker Through the Wild by Tim Gallagher. This book provides a captivating blend of adventure and natural history, following a small group’s dedicated efforts to find a species that now is almost certainly extinct—but just might not be!

The Falcon Thief: A True Tale of Adventure, Treachery and the Hunt for the Perfect Bird by Joshua Hammer. A fascinating look at the world of falcon and egg poaching.

And One More for Montanans

If you really want to buy something special for your Montana birder or birding family, take the plunge on Birds of Montana by Jeffrey S. Marks, Paul Hendricks, and Daniel Casey. This remarkable volume summarizes just about everything that is known about more than 400 Montana resident, migrant, and vagrant bird species. Rarely a week goes by when we don’t dive into this book to learn about a bird we’ve seen or have been thinking about. The book occupies a prominent place on our shelves and is a prized acquisition in our bird book library. Click the image below to order.

A wonderful compendium of information about birds living in, frequenting, or just visiting Montana. As an author, I reference it constantly.

The Best Places to Buy Bird Books

With the holiday season screaming up on us, we thought it would be fun to explore some of the best places to browse, find, and buy bird-related books. For most birders, having a library of bird books multiplies the joys of birding. Not only are bird books educational, they are great fun and entertainment. I’m not just talking about field guides, either. Travelogs, scientific studies, memoirs, and natural history accounts all help make up the huge variety of offerings available to birders of all ages, interests, and abilities. The upcoming holiday season presents the perfect opportunity to get a lot of your shopping done while supporting the cool businesses that make publishing bird books possible. Let’s dive in.

For most people the first place to look is your local independent bookstores, many of which have excellent selections both of field guides and other popular bird-related books. If they don’t have something, they can easily order it for you for pick up or delivery to your home. Here in Missoula, we are fortunate to have several indie bookstores including Fact and Fiction, Shakespeare & Co., and The Book Exchange. Some other great Montana indie stores are listed at the end of this post. Don’t know if you have a good indie bookstore nearby? No problem! Simply jump onto the bookstore finder on the Indie Bound website and put in your location. This finder can be found here: https://www.indiebound.org/indie-store-finder.

Yours truly signing Birding for Boomers at the Pacific Northwest Booksellers Association convention in Portland—an important event for indie bookstores throughout the West.

Especially fun are bookstores that actually specialize in birds and birding. Recently, I had the pleasure of doing book signings at two of these. While visiting my pal Scott in California, I signed my new book Birding for Boomers at Buteo Books. Buteo Books has spent decades building a reputation as the go-to source for birding books. While traditionally a mail-order and online store, new owner Lyzy Lusterman has taken the bold step of opening a brick-and-mortar store in San Rafael. Scott and I were positively giddy looking at the thousands of titles surrounding us and in no time I had plonked down more than $100 on birding books.

Buteo Books’ new brick-and-mortar store in San Rafael, California is a birders’ dream. Stop by when you’re in the area!

The week after my visit to California, I got to meet dozens of indie bookstore owners at the annual convention of the Pacific Northwest Booksellers Association. While in Portland, I also had the chance to sign at the incredible gift store of the Bird Alliance of Portland (formerly Portland Audubon). Like Buteo Books, this store has an amazing collection of bird-related books, not to mention an excellent selection of binoculars and other merchandise. I urge anyone in the area to drop by—and, while you’re at it, go birding on the great hiking trails leading out from the center.

The Bird Alliance of Oregon in Portland is the perfect place both to go birding and shop for bird books!

Experienced birders have no doubt realized that a couple of large university presses release more than their fair share of bird-related books. Princeton University Press has a huge variety of field guides and other bird-related books. Better yet, through the end of October it is offering a 70% discount on many of its titles—an incredible markdown that Braden and I have jumped on in the past.

The biggest name in birding, Cornell University, also aggressively publishes field guides and other bird-related books. Check out Cornell University Press here: https://www.cornellpress.cornell.edu/book-listing/?q=birds

Just a few of our own bird-book-lined bookshelves! Many of these are published by Princeton’s and Cornell’s university presses.

You also will find nice selections of bird books in local birding supply stores such as Birds & Beasleys in Helena, Montana, Backyard Bird Shop in Portland, Oregon and stores that are part of the Wild Birds Unlimited Nature Shops chain. Their store locator site can be found here: https://www.wbu.com/store-locator/

Of course, if you have any questions about Birding for Birders or my other bird-related books, don’t hesitate to reach out.

So that’s it for now. In our next installment, we’ll discuss some of our favorite birding books. Until then, get out there and bird!

Just a Few Other Great Montana Independent Bookstores:

Billings: This House of Books

Bozeman: Country Bookshelf, Isle of Books

Butte: Isle of Books; The Corner Bookstore

Dillon: The Bookstore

Great Falls: Cassiopeia Books

Hamilton: Chapter One Book Store

Chasing Migrants, Part I: Swifts, Peeps, and Plovers

In case you missed our last post, be sure to check out my new book, Birding for Boomers. It’s a great gift for anyone you know of any age or background who might be interested in getting into birds. It’s also a great way to support our efforts here at FatherSonBirding! Why not order one or two copies—or even a dozen—right now?

I’ve had little time to catch up on our birding adventures this time of year. With new books to promote, house guests to entertain, seeing Braden off to his senior year at UMaine, and more, life has been a juggling act through August and September. I did manage two lovely trips to Freezeout Lake in August, one with my occasional birding buddy Steve Flood, the other with Braden right before he headed East. In mid-September, I also rewarded myself with a personal trip to the Bay Area to visit friends and relatives—and, of course, see as many birds as possible. Like the recent trips to Freezeout, my primary objective was to find and study as many migrating shorebirds as possible.

Despite birding for more than a decade, I still feel like a beginner when it comes to shorebirds. My recent trips to Freezeout were “study sessions” more than birding excursions, and I was grateful that Baird’s Sandpipers, Red-necked Phalaropes, Semipalmated Sandpipers and other species offered hours of observation and ID practice on each trip. I hoped for similar sessions in California. After I spent a few days with relatives in Oakland and reconnected with the delightful birds of oak woodlands, my friend Scott (see Eastern Odyssey 24: Return to Westby) whisked me off to the North Bay, where serious birding adventures commenced.

Before heading across the Richmond Bridge, we gave McLaughlin Eastshore State Park in Berkeley a try, but our timing was off as high tide covered the mudflats. Next, we visited the Las Gallinas Valley Sanitary District in Marin County. I enjoyed that, but again, we saw nothing spectacular. I was surprised to spot a lone Vaux’s Swift—a lifer for Scott—and eight or nine Black Phoebes put on a show, but it was a slow start to meeting our birding ambitions. Fortunately, things would pick up—dramatically.

Though they didn’t perch at the top of our target list for the day, Black Phoebes charmed us at the Las Gallinas water treatment ponds in Marin County.

After Las Gallinas (“The Hens”), Scott drove us to Reclamation Road in the San Pablo Bay National Wildlife Refuge, where we hoped—finally—for some shorebird action. Our first surprise wasn’t shorebirds, however. As soon as we got out of the car, I spotted four tiny shapes frantically flying west. “Hey, there’s more Vaux’s Swifts.” I really hadn’t expected to see these, but it did make sense. I knew they’d departed Montana in the past few weeks and that they followed the West Coast down to their wintering grounds in Mexico and Central America. Our four birds were merely a prelude, however. As Scott and I walked out toward the shore, we saw half a dozen more swifts. Then a dozen. Then, as we looked east, we witnessed a veritable river of Vaux’s Swifts flying toward us.

This photo doesn’t begin to capture the remarkable river of migrating Vaux’s Swifts that passed over our heads. Yes, those “dots” are the swifts! Swifts are a species of concern because of the loss of old growth forests and other natural roosting sites. Ironically, saving old brick chimneys should be a priority for those interested in protecting these birds.

“This is amazing,” Scott said as the birds stiff-winged it over our heads. “Have you ever seen anything like this?”

I shook my head. The most VASWs I’d ever seen at one time was perhaps a couple of dozen. Now, hundreds streamed past us—probably thousands! We learned from a passerby that they were most likely heading to the chimney of an old brick-making plant, a well-known roosting place for them. Scott and I were suitably awed by the sight. It was enough to make the whole day worthwhile, whether or not we ended up seeing shorebirds.

Nonetheless, as we walked out to the bay I was gladdened to see shallow mudflats and hundreds of dots scattered over them. “Shorebirds!” I rejoiced.

With San Francisco in the distance, you couldn’t ask for a more dramatic setting to study shorebirds! Many of those specks in the foreground are Least Sandpipers—though you’ll see a lot of other species mixed in!

As we drew closer, I set up the spotting scope, and quickly zoomed in on a dozen-plus Long-billed Curlews, at least fifty Willets, and what would turn out to be a couple of hundred Marbled Godwits. These were easily-enough identified. Not so the hundreds of small sandpipers, or “peeps,” that peppered the scene in front of us. Birders generally include four species under the “peep” category: Sanderlings, Western Sandpipers, Semipalmated Sandpipers, and Least Sandpipers. Since it was the nonbreeding season, Sanderlings should have given off a distinctive whitish vibe by now, so I ruled them out, but what of the other three? The problem with peeps is that their coloration, size, bill shape and bill length overlap to a frustrating degree, and I just didn’t have enough experience with these to make a call. Least Sandpipers can be easy to pinpoint if you can see their leg color—yellow compared to black for Westerns and “Semipalms”—but when they were feeding in the mud, determining leg color often proved impossible.

As I often do in such situations, I called Braden. I described what I was seeing and said, “I am guessing that they are Semipalmated Sandpipers, but I just don’t know.”

“Well,” he informed me, “the good news is that if there are large numbers of them, they aren’t Semis because Semipalmated Sandpipers don’t move through the West Coast.”

With Braden’s help, I narrowed down these far-away “peeps” to either Least or Western Sandpipers. Confirmation would have to wait until later, however.

Doh! This surprised me because we do see them in Montana. I never realized, though, that our Montana birds were on the western edge of their migration pathway from their northern breeding grounds to their wintering grounds in the coastal tropics.

“If I had to guess,” Braden continued, “I’d say you’re looking at Least Sandpipers. You said that they’re darker brown and Westerns give off a grayer color.”

Still, even through the scope, the birds were too far away for me to be sure, so I recorded “peep sp.” in my eBird checklist—at least for now.

One species, however, excited me more than all the others. Almost as soon as we reached the mudflats, I spotted birds that I had especially hoped to see: Black-bellied Plovers. Black-bellied Plovers are one of the world’s largest plovers, and they have the widest distribution. Like many shorebirds, they breed mainly in the arctic regions, but in winter they disperse to coastal areas of every continent sans Antarctica.

At San Pablo Bay NWR, I was especially excited to see Black-bellied Plovers mixed in with Long-billed Curlews, peeps, Marbled Godwits, and other shorebirds.

Braden and I had only ever seen Black-bellied Plovers about twenty times—and only four times as they migrated through Montana. The birds are known to flock up in winter, but even in places such as California and Texas, we generally only saw a few at a time. Now, as I trained my scope out over the mudflats, I began picking out more and more of these birds. At first, their light color and larger size made them look kind of like gulls, but their more erect posture and stubbier dark bill gave them away. One bird they can easily be confused with are American Golden Plovers, which look almost identical except for their smaller bill, head, and overall size. Some AGPLs also show flecks of gold color even in winter, but today, I saw no AGPL suspects and counted sixty Black-bellied Plovers in front of me.

“I don’t think I’ve ever seen this many before!” I effused to Scott. “This is really amazing.”

What I didn’t realize is that I vastly undercounted. I took a couple of photos of shorebirds in flight and later, going over the images, I made a startling discovery. One of the flying flocks consisted of at least 140 Black-bellied Plovers! How could I tell they were BBPLs instead of other shorebirds? In this case, it happened to be easy. Black-bellied Plovers are the only shorebirds to show distinct black armpits under their wings!

When I took this photo, I didn’t realize these birds were Black-bellied Plovers—easily the largest flock I have ever seen. The black armpits make IDing this species particularly easy in flight.

It was a great way to end the day for both me and Scott and we celebrated with a fabulous Mexican food dinner with Scott’s wife Ginny and step-daughter Hayley. I went to bed happy—but eagerly looked forward to more migrating bird opportunities ahead.
