World Series Birds in the Golden State

A happy by-product of our second child going to school in California is that Amy and I have the perfect excuse to go visit the Golden State. Not that I would ever do any birding during a family trip, but you know, it’s hard not to see some great birds when you just happen to stop at a wildlife refuge or stumble into a local park that happens to be a bright red eBird hotspot!

I was especially excited to head to California a couple of weeks ago because, as previously reported, I was perilously close to breaking my all-time single year species record of 527 birds. In fact, when Amy and I landed in Sacramento and headed up to Chico, I needed only one bird to hit 528 species for the year. What would my “go ahead bird” be? (And yes, that is an homage to the upcoming World Series, which happens to feature a team named after birds!)

**Visiting our youngest in California has given me a great opportunity to see friends and get in some bonus birding!**

When we arrived, I quickly finagled a couple of birding opportunities, but saw only species I had seen on our last trip to California in August: California Scrub-Jays, Acorn Woodpeckers, Yellow-rumped Warblers and the like. My biggest discovery was a White-winged Dove at the Panera’s near the hotel! It was a rare bird so far north in California’s Central Valley, but not unheard of. Still, I felt proud to have spotted the distinct white stripe across each wing as it flew—undoubtedly hoping to score one of Panera’s kitchen sink cookies!

The next morning, I headed out to the home of a close childhood friend who just happens to live outside of Chico in an agricultural area. I had almost reached her place, when I noticed birds feeding on a coyote carcass on the side of the road. I saw Turkey Vultures and ravens. Then, I saw something that got my heart racing: magpies!

**My All-Time Best Year Record Breaker: Yellow-Billed Magpie! Whoo-Hoo!** **(Photo from earlier trip.)**

Not just any magpies. I knew that the Black-billed Magpies we had back home in Montana were unlikely in this part of California. No, these were Yellow-billed Magpies—a bird I had failed to see on our last trip in August! Ka-ching! My record shattered like falling glass! And with a California endemic species no less! Personally, I couldn’t have been happier. YBMAs are some of my favorite birds, and hold an interesting history, too:

“This species was named by John James Audubon in 1837 (as Corvus nutallii, corrected the following year to nuttalli) in honor of the ornithologist Thomas Nuttall, who collected the first specimen near Santa Barbara, California. Nuttall was a prodigious botanical collector and ornithologist who authored a Manual of the Ornithology of the United States and of Canada.” —Birds of the World database by Cornell Lab of Ornithology (accessed Oct. 19, 2025)

Later that day, I picked up an “insurance bird” at the Llano Seco refuge just southwest of Chico, where Amy and I delighted in Sandhill Cranes, Black-necked Stilts, and my 529^th bird of the year, Greater White-fronted Goose.

Greater White-fronted Goose was a great “insurance bird” for my record-breaking year—just in case the Birding Powers That Be decided to lump a couple of species together or I found a mistake in my earlier checklists!

But my fall California birding adventures had just begun!

After a few wonderful days with our child, Amy flew home from Sacramento, and my high school buddy Scott (see Scott’s Guest Post about the Morro Bay Bird Festival), picked me up for an additional four days of exploration. As I’ve mentioned, my emphasis lately has not been so much chasing target species, but exploring places I’ve never before birded, and Scott indulged me to the hilt. After he collected me in Sacramento we explored the Sacramento River delta, hitting Cosumnes River Preserve, where we got a little shorebird action—and a LOT more Sandhill Cranes and Greater White-fronted Geese. On the following days, we hit a huge variety of habitats as we hiked through oak woodlands, explored the large abandoned—and very birdy—grounds of the Sonoma Developmental Center, and scoured rocky shores and intertidal areas in American Canyon, Golden Gate National Recreational Area, Bolinas, and Bodega Bay. I loved every location and, not surprisingly, my “insurance bird” list grew.

Scott and I enjoyed a wet hike through Sugarloaf Ridge State Park in Sonoma County and fortunately, the rain did not dissuade the birds as we sighted a host of classic oak woodland species including Oak Titmouse, Golden-crowned Sparrow, and Nuttall’s Woodpecker.

I picked up Mute Swan in American Canyon as Scott and I gleefully observed thousands of shorebirds including Western and Least Sandpipers, Long-billed Dowitchers, Marbled Godwits, and Black-bellied Plovers. That afternoon, we saw my FOY (First Of Year) White-tailed Kites at a place called Buchli Station Road.

Our adventures gave us plenty of time to learn more about peeps as we picked out the subtle details of Least and these Western Sandpipers. Note the rufous shoulder patch (not always present), black legs, and longer, curving bill that distinguishes these Westerns from Least’s.

Our favorite—and most productive—day happened October 15^th. With a visit to Rodeo Lagoon, we found one of my favorite California birds, Wrentits, along with Western Gulls, which I had somehow managed not to see the entire year! At the nearby Bolinas Lagoon, we also observed hundreds of Elegant Terns and my trip MVB (Most Valuable Bird), a Whimbrel.

**This Whimbrel at Bolinas Lagoon nabbed Bird of the Trip honors as it was the first WHIM I’d seen in more than six years.**

Another bird I had somehow failed to see all year was Red-shouldered Hawk, but as we made our way north toward Point Reyes, Scott suddenly shouted, “Red-shouldered!” We pulled over to look at this handsome creature perched on a power line and even got to see it nab some kind of morsel from roadside weeds. The funny part? We saw four more Red-shouldered Hawks on our drive back to Scott’s house in Glen Ellen! I call that a Grand Slam!

**I don’t know that I’ve ever appreciated Red-shouldered Hawks more than I did this one—especially when it launched after some prey!**

One thing that made the trip so fun was eating lots of great food and kicking back to watch the MLB playoffs with Scott each evening. I hadn’t seriously watched baseball since Amy and I were still childless more than twenty years before, and it was wonderful to lean back, relax, and watch grown adults try to hit balls with sticks. Goooo Ohtani!

For our final day of birding, Scott drove me to Bodega Bay, one of my favorite places in California. While studying at Cal I had taken an ichthyology course here one summer, and now that I was a birder, the place held even more charm. On the rocks below Bodega Head, Scott and I were astonished to see a group of sixteen Surfbirds—far more than I had ever seen in one place! We also got great looks at both Brandt’s and Pelagic Cormorants, and spotted a Pigeon Guillemot in the far distance.

Since Braden and I saw our first Surfbird from a distance during our first pelagic cruise in Monterey in 2016, these birds have held a special place in our hearts. Never, though, have I seen so many in one place! (Can you also find the lone Black Turnstone in this photo?)

After a lunch of fish tacos, we headed up to the beaches north of Bodega Bay and were treated to a second Whimbrel sighting and more than 120 Surf Scoters casually ducking the breakers offshore. It was a wonderful way to wrap up the trip, and I am grateful to Scott both for being such a great host and for his patience when I was experiencing a blood sugar meltdown at Bodega Head. Of course, you may be wondering where my year list stands now, and I’m happy to report that I am now at 537 species. Will there be any more? I don’t know, but 550 seems awfully tempting, so stay tuned!

Update: Just before posting this, I picked up bird #538 for the year, Lapland Longspur, in some fields northwest of Billings!

**Can one ever get tired of Surf Scoters? I don’t THINK so!**

Just for fun, can you name the birds and places above? Answers in the nest—I mean next—post!

Swift-ecta!

In an earlier post, we may have let slip that both Braden and I are on a tear for our 2025 global species lists (see our post In Search of the Green-tailed Towhee). That’s due to a variety of factors. Braden not only drove across the country from Maine to Montana this past spring (see last post), he embarked on intense birding trips to Oaxaca, Mexico (see post Birding in Oaxaca, Mexico) and Costa Rica. As for me, I received delightful last-minute invitations to Colombia (post Antpittas and Tody-Flycatchers), thanks to FSB contributor Roger Kohn, and to Texas, where I spoke about my book Birding for Boomers. The upshot of all this is that Braden has seen almost 800 species of birds this year, while I am within twenty birds of breaking my all-time record of 527.

The thing is, twenty birds in Montana in late July is more challenging than it sounds. Birds common in May or June become increasingly difficult to detect and find, so if you don’t have them by August you may not get them at all. That means you’ll have to rely on migrants—which are notoriously unpredictable—or winter arrivals that you probably got earlier in the year. As a result, I’ve recently been focused on picking up the remaining common birds that I so far haven’t seen. Top on my list? Say’s Phoebe.

**Last year, I saw a Say’s Phoebe near the base of Missoula’s Pattee Canyon. Alas, that one eluded me this year, forcing me to search farther afield!**

Say’s Phoebes are cool little flycatchers that love to nest on human-made structures such as barns, covered porches, and utility buildings. While not rare, they seem to be pretty picky about their accommodations, and we run into them only infrequently in Montana. As I write this, for example, only four sightings have been reported in Missoula County in the past month. While scouring eBird, though, I did note regular sightings up at Kerr Dam below Flathead Lake. Braden and I had discussed doing a birding day trip, so two Tuesdays ago we set out early, Say’s Phoebes our Number One goal.

Before leaving Missoula, Braden asked if we could stop at Greenough Park. He had been pursuing a birding challenge with friends back East to see how many species they could find every day for seven days in a row. “I want to pick up Lazuli Bunting and Swainson’s Thrush,” he told me. This search happened to lead to the first delightful surprise of the day. As we were walking up a dirt trail, we approached a cottonwood tree where Braden had found a Western Screech Owl two days before. Today, he suddenly exclaimed, “Oh my god! It’s a baby!” Sure enough, a WSOW baby sat only a yard from its parent about twenty feet up the tree. Here, our day had just begun and already it had been a wonderful outing!

**This adorable little guy was the first baby Western Screech-Owl Braden and I had ever seen!**

Still, we had a lot of ground to cover. After a fortifying meal at our favorite French restaurant, McDaniels (in honor of Rogére), we headed up to Ninepipe NWR. We didn’t have any major agenda there except perhaps to snag some shorebirds. For July, it was an unusually cool, overcast day and we joked that we might see some Black Swifts. For those unfamiliar with Black Swifts, they are one of the most elusive and rare birds in the US. They nest mainly behind waterfalls and, especially with climate change, are highly vulnerable throughout their range. In Montana, I had never seen one outside of Glacier National Park, and it was pie-in-the-sky logic to even hope we might see one here out in the valley.

**Braden poring through intermolt ducks at Ninepipe.**

Anyway, we stopped at one Ninepipe pullout just off Hwy 93. The ducks were in their almost-impossible-to-identify intermolt plumages, but we still saw a nice variety of them plus Trumpeter Swans, American White Pelicans, Double-crested Cormorants, and Great Blue Herons. “Where are the Black Swifts?” I pressed Braden, but he shrugged off my flippant remark.

**Though we hadn’t seen any Black Swifts, the low cloud cover at least admitted the possibility that they would venture down into the valleys from their mountain waterfall hideaways.**

The phoebes on our minds, we didn’t want to spend too much time at Ninepipe, but decided to stop at one more pullout and, again, found the usual suspects. We both searched the skies for Black Swifts just in case, but didn’t see any. “I have to go to the bathroom,” Braden said, and I kept looking around for various birds. As soon as Braden emerged from the outhouse, however, he shouted, “Black Swifts!” Huh? My eyes darted back toward the low clouds, and there they were—four unmistakable dark shapes scything through the air!

**Black Swifts were a stunning find on a day for which we had almost no expectations.**

Though I’d seen Black Swifts before, this was my first time really getting to study them, and I noticed both similarities and differences between other swifts. Like other swifts, BLSWs have distinctive almost sickle-like shapes when they fly. With a wingspan of eighteen inches, however, they are significantly larger than Montana’s other swifts, and this shows in their flight. While Vaux’s Swifts zip around with almost mechanically stiff rapid wingbeats, Black Swift wings bend more noticeably. They still look like advanced jet fighters as they zoom through the sky, but with more flexible bodies. Braden also pointed out that Black Swifts show noticeable forks in their tails compared to Vaux’s Swifts, which look like their tails have been chopped off with a cleaver.

Swifts can usually be distinguished from swallows by their stiff-winged, scythe-like silhouette. Note the prominent fork in the tail of this BLSW that distinguishes it from Vaux’s Swifts—though White-throated Swifts can also show a fork.

We watched these rare beauties for a full five minutes before they drifted away across the lake and I even managed some cool photos. After they had gone, Braden and I just looked at each other. “Black Swifts,” he said, and we gave each other a hug.

**Swifts always remind me of fighter jets—captured here doing an F-35 impersonation.**

Remarkably, it was still only 8:30 and we had a ton of birding ahead of us. Our next stop was the roadside rest stop just south of Ronan where we picked up lone Semipalmated, Spotted, and Solitary Sandpipers, along with a pair of Long-billed Dowitchers, all undoubtedly in migration. After that, we headed to Pablo NWR in hopes of some interesting water birds. We struck out on those—but were amazed to see more than 300 Bank Swallows resting on the dirt road. “They must be migrating, too,” Braden marveled, and I agreed. In fact, it has been a very lucky swallow year for both of us with, for example, great looks at large numbers of migrating Tree Swallows and Cliff Swallows. This was the first time we’d ever seen Bank Swallows in such numbers, though. From there, it was on to our primary destination: Kerr Dam.

Braden had never been to Kerr Dam before, and I’d just gone to the overlook, but the entire site reminded me of a throwback to gentler, more civic times, when people shared more of a vision for the common good. From the overlook, we looked down on the dam itself with the Flathead River backing up into Flathead Lake beyond. Below the dam, dramatic, highly eroded cliffs framed a dramatic canyon full of promising riparian habitat.

**Braden and I both wondered what secrets the dramatic cliffs below Kerr Dam might be hiding!**

From the overlook, we watched Ospreys and Braden said, “Look, there are some Violet-green Swallows. White-throated Swifts should be here, too.” Not two minutes later, he spotted a pair flying overhead, their sickle-shaped wings and white breasts clearly visible against the blue sky. “Uh-oh,” I said. “That means that we might have to go for the Swift Trifecta and find some Vaux’s Swifts.” Braden sighed in agreement. Darn those swifts!

But we had not forgotten our main target, Say’s Phoebes. “I’m guessing they are down there at the power station below the dam,” I said. “You up for going down there?”

“Sure.”

**Squinting into the sun at the overlook to Kerr Dam, the Flathead River running south below the dam in the distance.**

Winding our way down to the power station, we were greeted by a cluster of neatly-kept houses and a fenced-in area full of transformers and other “power stuff.” All of this was surrounded by an open, pleasant park-like setting that reminded me of my days working on the Pitt River dam network in northern California just after college. We decided to get out and walk around and immediately started seeing and hearing Western Wood-Pewees, American Goldfinches, robins, Eastern Kingbirds, and other songbirds. We hadn’t walked ten minutes when suddenly, some kind of flycatcher darted out in front of us to snag an insect.

“Say’s Phoebe!” I exulted, and Braden gave me a high five. There weren’t just one, but two, working the area around the fenced-in transformer area. “This is perfect for them,” I said. “Lots of insects and plenty of structures to nest on.” Alas, they didn’t care for our attentions and kept flying away as we approached, but they and the Black Swifts brought my global year total to 509 species—just nineteen shy of breaking my record of 527. Braden already had the phoebe for the year, but the Black Swifts took his global 2025 total to an astonishing 776 species! BUT . . .

**This elusive Say’s Phoebe finally cooperated with me for 2025!**

There was still that little matter of a swift trifecta on our minds. After a cultural stop at Richwines Burgerville in Polson, we made our way slowly back to Missoula. Nowhere did we see the third Western Montana swift, Vaux’s Swift. “Let’s go to Caras Park,” Braden suggested as we reached Missoula. “I see them there pretty regularly.”

We parked near the iconic metal salmon sculpture and walked out onto the grass below the Higgin’s Street Bridge. The sun was out by now and things were warming up. Cliff Swallows flew to and from their mud nests on the side of the bridge, but I didn’t expect to see any swifts. “There’s one!” Braden suddenly shouted. Sure enough, several birds with fast, mechanical wingbeats darted back and forth after insects above the Cliff Swallows. It was a final satisfying sighting on a totally surprising, remarkable July day in Montana.

Our Day’s Trip Report: https://ebird.org/tripreport/396651?welcome=true

The small size and “chopped off” tails of Vaux’s Swifts are solid ID features to distinguish them from both Black and White-throated Swifts. These wonderful little birds completed our Western Montana “Swift-ecta” and wrapped up one of our best birding days ever.

Hi-Line Report: Bad Weather Can Bring Good Birds

Most serious Montana birders try to make it up to the Hi-Line every year. If you’ve never heard of the Hi-Line, it is the northern region of the state that basically follows Highway 2 from East Glacier National Park all the way to the North Dakota Border. It’s an area full of rolling hills, badlands, farms and ranches—and a whole lotta birds. For Braden and me, the region is best represented by the Bowdoin National Wildlife Refuge, a sprawling 15,551-acre refuge near Malta that encompasses a rich variety of wet and dry habitats. We don’t make it up to Bowdoin every year, but this year I was fortunate enough to get invited to visit a school in nearby Chinook. Even better, I timed the visit for spring migration and breeding. I booked an Airbnb in Malta and drove up two days early to give me a full day at Bowdoin. The bad news? The forecast called for rain.

Indeed, when I arrived at the refuge at 6:00 a.m., rain pelted the car, propelled by a cold wind. Geez, I thought. I’m not going to see anything today. It was so cold and wet that I skipped my usual stop at the visitor center and instead headed straight out onto the first, five-mile section of the fifteen-mile loop around the lake. I noted that water levels, although not great, were better than I’d seen them two years before, but the first five-mile section was a time to focus not on water birds, but on denizens of the grass. Normally, in fact, Braden and I spend the most time in this section, stopping frequently to listen for Grasshopper Sparrows, Baird’s Sparrows, Chestnut-collared Longspurs, and other grassland favorites (see our post “Great Grassland Birding”). Today, that proved impossible. Every time I opened the window, wind and rain cascaded in and made it almost impossible to hear calls beyond the heavy-metal songs of Western Meadowlarks.

**Steady rain and wind limited my ability to find grassland birds!**

Mercifully, a few species took pity on me. Right off the bat, I espied one of our favorite birds, a Bobolink—the only one I would see the entire trip. Then, I spotted a drenched Grasshopper Sparrow perched on a small bush—the lone GRSP I would see that day. Lark Buntings also put in an appearance, along with Horned Larks and Savannah Sparrows. I also was pleased to see shorebirds, but on this section of the drive, they were far away. At one point, I leaped out to set up the scope I was testing out (see our next post), but immediately got drenched and was unable to ID much except for Wilson’s Phalaropes, American Avocets, and a Willet.

**Lark Buntings were the most cooperative grassland birds I managed to see on this cold, wet, windy day. Thank you, Lark Buntings!**

As I kept driving, however, conditions steadily improved and I got better looks at shorebirds. The phalaropes were especially impressive and I estimated at least a thousand out on the water and working the shore. The vast majority were Wilson’s, but with patience, I found a group of four Red-necked Phalaropes—most clearly identified by their smaller size, overall darker appearance, and distinct light lines running down their dark backs. Ducks were not super abundant, but plentiful and I counted at least ten species, including my first-of-the-year Canvasbacks!

Twice, I drove down to some boat ramps and, despite the rain, nabbed a good “harvest” of shorebirds. I found about half a dozen Semipalmated Sandpipers and one Western Sandpiper. The real surprises, which I confirmed later with Braden’s help, were a Baird’s Sandpiper and a White-rumped Sandpiper! The latter was especially difficult to figure out because it didn’t readily show the diagnostic, thin lines of spots extending from the neck down to below the wings, but the overall appearance and body size fit. I was thrilled to find these birds as we’d never found them at Bowdoin before. Then again, we’d never birded Bowdoin this early in the season, so they were all part of my continuing Montana birding education.

**Both this Baird’s (left) and several Semipalmated Sandpipers (right) proved early season surprises on this cold, rainy Bowdoin day.** **The larger size, long wing tips extending beyond the tail, and “medallion” appearance on the wings help distinguish Baird’s from the smaller peeps.**

As I was leaving the second boat ramp, I noticed a Marbled Godwit in the parking area. Godwits, like Willets and Long-billed Curlews, are shorebirds and grassland birds. They nest in grasslands, usually near water, so seeing one here didn’t surprise me. I was about to drive off when the godwit suddenly launched itself. As I watched, it flew a hundred yards or so to the shore—and landed next to two birds I had especially hoped to see: Black-bellied Plovers! Loyal FSB readers will note that I’ve written about these fine birds a lot in the past couple of years (see, for instance, this post), and so it was with special pleasure I observed them now—and in their best black-bellied breeding plumage. Thank you, Mr. Godwit, for pointing them out!

**This helpful Marbled Godwit (right) made a special effort to point out two Black-bellied Plovers that I had so woefully overlooked!**

By the time I made it back to the visitor center, my stomach rumbled and, though the rain had slackened, the cold and wind remained. I debated whether I should even get out of the car to explore around the small pond there, but I knew that Braden would never forgive me if I didn’t. Marshaling my determination, I walked over to the start of the little path that circumscribes the pond. Almost immediately, a curious face popped up from behind a bush thirty feet away. “Whoa!” I whispered. At first, I thought it was a weasel, but it was much larger than the three or four weasels I’d observed in the past. Stoat? Ferret? I asked myself. Could it possibly be a mink? I’d never seen a mink and didn’t know if they even lived in Montana, but it seemed to fit the profile. Later, iNaturalist experts helped me confirm that that’s what it was. After looking at me for several moments, the long, bizarre-looking creature loped across the road and disappeared into the brush. The birds, however, were not to be outdone by a mere mammal!

**Seeing my lifer American Mink was about the last thing on my mind as I braved Bowdoin’s visitor center area for one last birding effort!**

As I began poking around the beginning of the trail, I saw shapes flitting about in the bushes. A brownish bird streaked by me giving off Swainson’s Thrush vibes, but I didn’t see it well enough to definitely identify it. Minutes later, a reddish-backed bird landed on a nearby branch below me—a Veery! Then I got a good look at another Swainson’s Thrush, this time confirming the ID. In the branches above it, an adorable little Least Flycatcher watched me, but none of these would be the stars of the show.

Empidonax flycatchers are notoriously difficult to identify by sight, but this bird’s “cute” appearance—and the fact that no other empids should have been anywhere in the area—helped clinch the ID.

Even through the wind, I could hear both Yellow Warblers and Common Yellowthroats around me, even if I couldn’t get clear looks at any of them. Then, a small songbird landed in a tree about thirty feet away. I got my binoculars up in time to recognize a species I had longed to see—a Blackpoll Warbler! Like the Swainson’s and Veery, the warbler was clearly in migration, on its way to northern breeding grounds in Canada and Alaska. Braden and I had found them three times before in Montana, but always females. Not only did a gorgeous, breeding plumage male now stare back at me, it was the first Blackpoll I had ever found on my own!

**As you can tell, the day proved tough for photography all-around, but I managed to get fuzzy ID photos of my Bird of the Trip, Blackpoll Warbler!**

You won’t be surprised to hear that the Blackpoll Warbler immediately secured Bird of the Trip honors. Even more, it cemented the notion that just because conditions are bad for birders, they can still be great for birds. In fact, storms often cause birds to hunker in place for a day or two—perhaps the reason I found some of the especially cool birds I found today. I plan to remind myself of that the next time I’m debating whether to venture out into the pelting wind and rain.

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

6 Replies

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!

These Red-necked Phalaropes and a lone Pectoral Sandpiper were the highlights of our walk around the lagoon to the beach.

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.
