Morro Bay Bird Festival report (Guest Post by Scott Callow)

(All photos copyright Steve Rosso or Scott Callow.)

My former work colleague, Steve, and I spent 2 hours deciding which walks and talks we would do at our first winter Morro Bay Bird Festival. It was just over a week since the registration opened. Everything we chose turned out to be full, even with over 263 events, 191 of them field trips.  Lesson learned. (We later learned that the Pelagic Boat Trip filled within an hour.) We were able to sign up for two outings, a Big Day at the inland Santa Margarita Lake and a “Back of the Bay” walk in Los Osos. Steve also made the wise demand to stop at the Pinnacles National Monument on our way down, and convinced me to spend the extra money ($55) on a boating tour of Morro Bay itself. (Readers are encouraged to open up a map of the region.)

On our trip down, we got good looks at a well-known California endemic, Yellow-billed Magpie (see post “College Search Birding in California”).

Our first stop was along the lonely Highway 25 between Hollister and Pinnacles’ east entrance. We badly wanted one soaring raptor to be a California Condor but it turned out to be a Golden Eagle. Later (2-3pm), at the observation overlook a mile up the Condor Gulch Trail, more than 15 dark soaring birds suddenly appeared as a group from behind the eroded sandstone Hain’s Peak. I confidently identified four as Condors, one as a Golden Eagle (clearly seeing the difference between each’s white markings on the undersides), and many Turkey Vultures. Steve’s new camera clicked away. At the trailhead, a ranger told us that, years ago, the population was below 10 individuals when reintroduction began and now the local population had swelled to “three digits.”

Pinnacles National Park. And yes, at least some of those black specks are California Condors!

The next morning we embarked on our first festival field trip: a Big Day at Santa Margarita Lake. It was led by Mark Holmgren, retired curator of the natural history museum and collection at UC Santa Barbara (my alma mater and where Sneed got his master’s degree). Highlights included comparing Eared, Horned, Western, Clark’s and Pied-billed Grebes, listening to Fox’s Sparrows, California Thrashers, and Wrentits, and observing raptor behavior. Speaking of, we saw Ospreys and Bald Eagles fishing (one birder theorized the adult eagles were teaching the juvenile), two Peregrine falcons mobbing a raven, and two Peregrines (perhaps the same) apparently fighting over food in mid-air or in courtship display. I got good looks at the yellow lores of a White-throated Sparrow.

Winter is a nice time to compare Clark’s (shown here) and Western Grebes, which can sometimes be difficult to tell apart. Clark’s Grebes have more orangish bills versus greenish-yellowish on Westerns. The black also rises above the eye on Clark’s, though that’s not as clear-cut on this individual.

Tired from our long day, we drove to the Morro Bay Community Center downtown and attended one of the two  receptions. Included in the cost of registration were free local wines (multiple pours allowed), and extensive noshing trays of cheese, meats, veggies, crackers, and artisan chocolates.  The adjacent bazaar impressed with booths for 3-4 high-end binocular/gear manufacturers, book shops, authors, nature art and nature organizations. The bazaar was well attended and the noise generated rivaled that of a Spring morning chorus.

The bird fest’s exhibit area had a nice variety of vendors and non-profits to occupy us between birding trips, talks, and meals.

Our dinner at Morro Bay’s affordable, healthy and creative Asian fusion cafe, Chowa Bowl is recommended, as is the lunch combo Big Deal of sushi roll and ramen noodles at Baywood-Los Osos’ funky hangout, Kuma. This is important info to a birder even though food and beverages are barely mentioned in The Avian Survival Kit chapter of Birding for Boomers. Good food and libations can elevate a birding trip. (Editor’s Note: We at FSB take exception to this criticism, as we have frequently mentioned fine dining establishments such as McDonald’s, Wendy’s, and Starbucks.)

Next day’s Back of the Bay trip was not only highlighted by lunch, but by Audubon’s Sweet Springs Nature Preserve. It’s a small preserve with a spring-fed creek and excellent views from its wooden observation decks of the bay’s mudflats and its shorebirds, ducks, gulls, and terns—tons of them (which is saying a lot since birds are so light.) With Morro Rock and Morro Dunes in the background, we saw Lesser and Western Sandpipers, too many Brants to count, 30+ Green-winged Teals, 4 Blue-winged Teals, American Wigeon, Northern Shoveler, Bufflehead, Long-billed Curlew, Killdeer, Black-bellied Plover, Great Egret, and Greater Yellowlegs. We learned the Greater has three notes in its call compared to the two notes of the Lesser. Ring-billed Gulls, Belted Kingfishers, and Forster’s Terns were seen flying above the bay.

These are the ducks that inspired The Guess Who’s 1970 Number One single “American Wigeon”. Fun Fact: Sneed saw The Guess Who’s lead singer, Burton Cummings, perform this song live in Rapid City, South Dakota in 1977. Sneed was favorably impressed by this performance—until ZZ Top took the stage and basically burned the place down.

In the narrow woodland area between street and bay we saw both Hairy and Nuttall’s Woodpeckers, and Chestnut-backed Chickadee. Then, local guide Dean led our car caravan down the road apiece to his friend’s house which sported about six bird feeders that earned a hot spot ranking on eBird. More chickadees, the ubiquitous House Finch, the most common local warblers—Yellow-rumped, Orange-crowned, Townsend’s—and Lincoln’s, Golden-crowned and White-crowned Sparrows. We also saw our Oak Titmouse, formerly lumped with Plain Titmouse, at the bird feeders. Its range is mostly endemic to California (stretching into parts of Oregon and Mexico) and the bird shares its place with the Acorn Woodpecker as a signature species in California’s oak woodlands.

Dean also shared his mnemonic for our (Pacific Group) White-crowned Sparrow – “Awf man!, I dough-ont wanna see”. It’s a bit of a stretch but “I don’t want to see” sums up many people’s  self-engineered denials of science nowadays, so I decided to add it to my mnemonic checklist.

The rarity highlight of the trip was the sole Blue-winged/Cinnamon Teal hybrid. I “put good eyes on it” but Steve left his camera in the car because he logically thought he’d get better shorebird and bay bird shots on the following day’s boating trip.

Female, juvenile, and nonbreeding Red-breasted Mergansers (above) can be difficult to distinguish from Common Mergansers, especially in winter, when they can be swimming side by side. We think this is a Red-breasted because of its a) slightly thinner, upturned bill b) indistinct transition between the brown and gray on its neck and c) its crazier “hair-do”.

Our inside-the-bay boat trip the next day also included a fellow (and local) birder, Mike, who led bird trips. Steve and I learned a lot from him. The trip was created as a photography outing and the leader focused on pointing out good shots. The captain, also a birder, put the boat in good lighting and locations for the photographers. We were inspired to overtip him. The trip started in a downtown marina and we made a loop up to Morro Rock, along the rock jetties past the bay’s opening to the ocean, and then back into the bay to the mudflats of the Morro Bay Estuary. As we returned back to the docks, we passed the Morro Bay State Park Boardwalk, the Museum of Natural History, the Morro Bay Water Access, and Heron Rookery Natural Preserve—all excellent spots to bird from the shore, and perfect for photographers from the water due to the sun’s location.

We saw Peregrine Falcons above The Rock, Black Oystercatchers and Black Turnstones on the rocks, Black-crowned Night Herons in the trees, Ospreys on the masts, Common and Red-breasted Mergansers, several Eared Grebes and a Horned for comparison, and a nice collection of Brandt’s, Pelagic, and Double-crested Cormorants floating on a wooden raft. The Brandt’s Cormorants were especially striking with their iridescent coats and bright blue throat pouches. We were surprised to see some of the adults sporting very early breeding plumage marked by brilliant white “whisker” feathers around the ears and shoulders.

Cormorants put on a show under the gaze of their Western Gull overlord. Note the brilliant blue gular pouches on the Brandt’s Cormorants, along with their wispy white breeding feathers on the necks. A Double-crested with yellow markings skulks in the background.

Further inside the bay near the mudflats we saw large numbers, reaching into the hundreds, of Double-crested Cormorants, Marbled Godwits, and other shorebirds too far away to ID, plus good showings of White Pelicans, Ospreys, Ring-billed and Western Gulls, Northern Pintails, Buffleheads and Long-billed Curlews, Willets, and Greater Yellowlegs, as well as other common shorebirds not listed.  Mike told us that the Pelagic Boat Trip ($160) was fantastic. If interested, check the bird list from the trip on the festival’s website.

Our “Inside of the Bay” boat trip featured a great variety of seabirds and shorebirds. Here, American White Pelicans earn extra style points.

The last night’s keynote speaker was Kenn Kaufman, author of Kingbird Highway, multiple nature guides, and his new The Birds that Audubon Missed: Discovery and Desire in the American Wilderness. He extolled birders to persist in their nature explorations, even beyond birds, and to pause the inclination to aggressively list in order to truly observe. He described the Morro Bay region as a “globally important ecological area” and the all-volunteer festival as top-notch and well organized, ranking it among the highest of the many he has attended. 

232 species were identified collectively during the 5-day festival in mid-January. Events included typical bird walks, birding by boat, bicycle and kayak, birding for youth, beginners and advanced birders, birding with wine and olive oil tastings. Sites extended beyond the Morro Bay area including the  Kern National Wildlife Refuge, the Carrizo Plains Ecological Reserve, various ranches, Atascadero, San Luis Obispo, and Pismo Beach. Check out the Long Report of the Festival Events Including Details on the website. More details than you will need to convince you to make next year’s festival are found at morrobaybirdfestival.org.

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!

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!

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

After our amazing encounter with Vaux’s Swifts and shorebirds (see our last post), Scott and I had another productive session the next morning at the Ellis Creek water recycling facility and Tubbs Island, both in Sonoma County. As an added bonus, we got to bird with two of Scott’s pals, Steve and Sean. Steve and Scott began birding about the same time and were still in the beginning phases of their birding careers, but Sean grew up birding and taught us all some cool ID features. Most important, he confirmed that the peeps Scott and I saw the day before were indeed Least Sandpipers. With his help, we were also able to identify a couple of sneaky Western Sandpipers that were comingling with the approximately 400 Least Sandpipers in front of us. As much as we enjoyed these sessions, what Scott, Steve, and I looked forward to the next day even more. That’s when we planned to bird legendary Abbotts Lagoon.

(L to R) Sean, Steve, and Scott investigating the wilds of the Ellis Water recyling plant!

Abbotts Lagoon sits within Point Reyes National Seashore, and none of us had ever before birded it. However, Braden and our occasional guest contributor, Roger Kohn, had both been there and given it high marks. As we crested the mountains at Point Reyes and drove down toward the coast, I didn’t know what we would find, but held my hopes high.

Reaching the beginning of the lagoon requires a mile or so hike through remarkable dwarf-like vegetation that reminded me of steppe or tundra, probably because fog enshrouded the lands around us. I hadn’t realized we would have to hoof it so far, but I was grateful because we got great looks at many California residents: California Quail, California Scrub-Jays, White-crowned Sparrows, and most exciting, Wrentits. One of these, in fact, popped up no more than fifteen feet from us—unusual for a generally secretive bird. Nontheless, it was the lagoon and beach beyond that propelled us forward and when we reached the lagoon we found . . .

Though a bit of a hike, the mile-long walk to the lagoon offered a nice variety of songbirds and raptors, including this banded White-crowned Sparrow.

Nothing.

Well, almost. Instead of vast rafts of shorebirds ripping up the mud, only a couple of wading birds and American White Pelicans could be made out as far as the eye could see. Darn, I thought to myself. But if there’s an, ahem, cardinal rule to birding it is this: You Never Know. So we plowed ahead, following the harder beach sand, and soon came to a little bend where we got great close-ups of three Red-necked Phalaropes and a Pectoral Sandpiper—a bird I recognized only from my hours studying them in Montana. This bird, in fact, was quite interesting because PESAs show up only in small numbers on the West Coast, and generally only in fall. A lifer for Scott and Steve!

Continuing toward the ocean, we spotted two Black-bellied Plovers and a flight of shorebirds in the distance, but it wasn’t until we reached the ocean that we got some real action.

I was just as excited by pelagic bird possibilities as I was by shorebirds, and once on the beach I immediately set up the spotting scope we’d lugged the two miles out there. Like shorbs, I rarely have a chance to observe pelagic birds, and I felt determined to make the most of this rare opportunity. Right away, I saw a number of dark shapes out on the water—shapes that appeared and disappeared on the four-foot swell. Oh man, I thought to myself, I’m never going to be able to figure out what those are. In such situations, I have learned to relax and just hang in there, and that’s what I did now.

From studying before the trip, I came up with several likely possibilities of species that could be out there. These included Common Murres, Pigeon Guillemots, various storm-petrels, and Sooty Shearwaters. In fact, as we arrived, I noticed at least eight medium-sized dark birds swooping low over the water. When they turned, I spotted light patches under the wings. First victory: Sooty Shearwaters.

Then, I saw a larger bird floating a couple of hundred yards offshore. The shape shouted “Loon” and I thought, “Hm, that looks like it has a silvery sheen on its head.” Victory #2: Pacific Loon!

Identifying pelagic birds at great distance can take great patience and not a little skill, but in time, many species reveal themselves. The keys to this Pacific Loon? A silvery sheen on its head, a thinner bill than found on Common Loons, and a thin black “chin strap” or collar around the neck.

After that, it got harder, but I did manage to ID some distant Common Murres by the white around the face and neck, thinner “up-pointed” bills, and longer body lengths. A seabird expert undoubtedly would have found additional species, but as a seabird novice, I felt satisfied. Humorously, as I was looking through the scope, I suddenly saw a whale’s tail emerge behind several of the birds. Did I look up? Of course not! Who has time for pesky mammals when there are ocean birds to be seen!

But let us not ignore the beach itself. As Scott, Steve, and I enjoyed the waves and emerging sun, the shorebirds decided to put on a show. On one side of us, a flock of at least 150 Least Sandpipers landed only a hundred yards away. On the other side, a couple of hundred Western Sandpipers settled down. Talk about your perfect conditions for comparison! In fact, this was my first chance ever to get good, leisurely looks at Westerns and I took full advantage of it.

The beach at Abbotts Lagoon offered by far my best opportunity ever to study Western Sandpipers. Note (if you can) the overall pale appearance and the reddish “shoulder blades” typical of juveniles this time of year. WESAs also tend to have longer, more curved bills than other peeps.

You remember that Sesame Street song “One of these things is not like the other?” Studying the Least Sandpipers, I spotted a much paler bird with a thick black bill and black legs. Another peep: Sanderling!

Meanwhile, among the Western Sandpipers, I espied smaller birds with shorter bills and dark collars around their necks—Semipalmated Plovers!

I was especially tickled to find half a dozen Semipalmated Plovers among the Western Sandpipers. Go plovers!

To add to the show, a Peregrine Falcon landed on the sand behind us, and on the way back we saw several other raptors including a White-tailed Kite. After Abbotts, we got a delicious lunch at Inverness Park Market, and then headed to Limantour Beach for great looks at Surf Scoters. All in all, it was an awesome day chasing migrants, featuring good birds, good food, and best of all, great company.

Compared to the Abbotts Lagoon Beach, Limantour Beach was a bit of a desert, but did offer up three nice Surf Scoters.

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.
