Bruce M. Beehler’s Flight of the Godwit: Tracking Epic Shorebird Migrations (Smithsonian Books, 2025)
Any birder who has aspired to learn about shorebirds will find a welcome companion in Bruce M. Beehler’s new book, Flight of the Godwit: Tracking Epic Shorebird Migrations. Shorebirds, after all, can be considered somewhat mythical, mysterious beings. Not only do many of them make remarkable annual migrations covering tens of thousands of kilometers, quite a few are notoriously difficult to identify. Certainly, Braden and I realized we had entered a more advanced stage of learning when we started to search out and try to identify shorebirds and, in fact, we both often still struggle with figuring out some of the more difficult shorebird species. Yet the more we encounter and learn about these birds, the more we love them—and that same kind of passion radiates from Beehler’s words as he sets out on his own journeys to observe and learn more about these birds.
In Montana, we are lucky to host three of the “Magnificent Seven” shorebirds as breeders—including Marbled Godwits, one of the focal birds of Beehler’s new book.
In Flight of the Godwit, Beehler recounts a series of recent adventures across the US and Canada to follow and observe shorebirds as they migrate north, stop over at resting and staging sites, settle on breeding grounds, and then head south again for their long non-breeding seasons. Although Beehler discusses all of our North American shorebirds at some point, he clearly targets what he calls the Magnificent Seven: Hudsonian Godwit, Marbled Godwit, Bar-tailed Godwit, Long-billed Curlew, Whimbrel, Bristle-thighed Curlew, and Upland Sandpiper. As he shares his encounters, he sprinkles in liberal amounts of natural history and personal experiences about these birds to make the book much more than a birder’s travelogue.
This Marbled Godwit checked us out as we were scoping shorebirds in Westby last summer.
That said, the travelogue aspects of the book are a big part of what fascinated me about this tale. Even after eleven years of birding, my shorebird experiences have been much more limited than I would like. Although my home in Montana is fortunate to host a number of breeding shorebirds—including three of the Magnificent Seven—for most shorebirds, we get only brief glimpses of them as they pass through in spring and fall. Partly because of this, Braden and I have especially sought out shorebirds on our out-of-state travels to Texas, New England, and the West Coast. Sigh. It is never enough.
It always surprises new birders that some of our largest shorebirds actually breed in grasslands—including Long-billed Curlews.
As I followed Beehler up through the Midwest during spring migration and around Alaska during breeding season, his experiences filled in giant gaps in my own experience with these remarkable birds. I got a better sense of where the birds stop to refuel and rest, and my vague impressions of their nesting territories and habits were sharpened by Beehler’s actual observations and descriptions. Many times, I found myself nodding my head thinking, Yeah, I know what he’s talking about or Oh, so that’s what they’re doing. All of this felt especially satisfying since there’s a good chance I will never experience many of Beehler’s destinations for myself.
As much time as I try to spend with shorebirds, it is never enough. Flight of the Godwit helped fill in many of the experiences I probably will never have for myself.
Those who will appreciate Flight of the Godwit the most probably are birders who have already spent time observing shorebirds and struggling over their identifications. Those with limited shorebird experience may find themselves getting a bit lost as Beehler throws out bird names that may seem a bit abstract without solid brain images to connect them to. Still, there’s a good chance that even beginning “shorbers” will find that Beehler’s tales of adventure excite them to plunge more deeply into this remarkable set of birds. As for intermediate and advanced birders—especially those who may never get to Alaska or follow spring migration through the Midwest—I highly recommend this intriguing book that is not only a valuable educational document, but a labor of love with which many of us can relate.
You can order Flight of the Godwit from almost any outlet that sells books—but why not visit your local independent bookstore and order it there? Another easy way to do this is through the online website Bookshop.org.

Late July often ushers in the birding doldrums. Having finished courtship and breeding, most birds get super quiet. They often disperse from their breeding territories, too, making them more difficult—or at least unpredictable—to find. But this year I was in luck: I had a writing assignment that would guarantee I see at least a few very cool birds.
My best look yet at a stunning Ferruginous Hawk proved a delightful bonus to my day near Bannack.
You may recall my unsuccessful June trip down to Beaverhead County (see post In Search of the Green-tailed Towhee) to visit with biologist Jeff Marks, founder of the nonprofit scientific research group Montana Bird Advocacy. There, Jeff and colleague Paul Hendricks are performing a long-term study on one of Montana’s little-known birds, the Gray Flycatcher. When I visited, Paul wasn’t there, but I also got to meet biologist and research assistant Nate Kohler, who has been playing a pivotal role in the study.
The word “gulch” conjured up a much more verdant image to my mind, but as you can see it takes some pretty special adaptations to survive in this rugged country.
Although my June trip allowed me to see many wonderful birds and interview Jeff and Nate, my intention to see the Gray Flycatchers got squashed by a freak winter storm. Worse, the storm wiped out a whole crop of nestling Gray Flycatchers. The good news? The adults had laid second clutches of eggs, and the babies were getting ready to fledge as I again headed down there the last week of July. This time, the weather would be ideal for seeing them.
Jeff and I headed out at 8:00 a.m. and made our way up Bannack Bench Road, which borders the study area. This was the third season of the study, and its purpose is to figure out some of the basic biology of a bird that scientists know very little about. To do that, Jeff, Paul, and Nate have been banding adult flycatchers with color bands that allow field identification and observation of individual birds. The birds have been a challenge to catch, but the biologists have managed to band about a dozen each year—and with fascinating results. I won’t reveal too much about those results here since I’m also writing an article for Montana Outdoors magazine that will be out next year. However, I will tell you that seeing where these birds nest and what they are doing was a thrill.
Biologist Jeff Marks takes notes on a Gray Flycatcher nest in his Beaverhead County study area.
When Jeff first told me they were working in a place called Sheep Corral Gulch, I imagined sagebrush plants bordering some kind of verdant riparian zone, perhaps lined with aspens or junipers. Imagine my surprise to see nothing but sagebrush in every direction! Gray Flycatchers breed throughout the Great Basin, but one of the fascinating things about them is that they choose different habitats in different places. In other states, they nest in juniper, pinyon pine, and even ponderosa pine, but in this part of Montana the birds breed almost exclusively in sagebrush plants along dry washes. One thing that these places share in common is that they have open ground for foraging.
Color-banded adults allow Jeff and the Montana Bird Advocacy team to make detailed observations about mating and behavior of these little-known birds.
In Beaverhead County, though, not just any sagebrush will do. The birds nest only in taller plants four to eight feet high—plants that can mainly be found growing in the (usually) dry main stream channels of gulches. This year, Jeff and his colleagues located about a dozen nests, one to two hundred meters apart, and as Jeff and I began hiking, it wasn’t long before we spotted an adult bird up ahead. Using GPS coordinates, it took only minutes for Jeff to locate the bird’s nest—a nest with babies!
“They will fledge any day now,” Jeff told me, “and it looks like both parents are feeding them.” Having two involved parents gives the nestlings a huge survival advantage, and as we watched, we saw a parent deliver a juicy grasshopper to its ravenous chicks.
Most of the Gray Flycatcher nests were bursting with babies itching to head out on their own—after a few more meals from Mom and Dad!
For the next three hours, I followed Jeff as we visited one nest after another, and most were jam-packed with two or three babies champing at the bit to head out on their own. We, of course, made sure to stay well back so as not to spook them out of the nests before they were ready.
An unbanded adult Gray Flycatcher keeps watch on us as we move through its territory: “Move on. Nothing to see here, folks.”
I thought we would see a lot of other birds as we hiked, but especially this time of year, the birds stayed out of sight. We saw a couple of Brewer’s and Vesper sparrows, and a single Sage Thrasher and Northern Harrier. What a contrast from a month earlier when I spotted Sage Thrashers and Brewer’s Sparrows almost everywhere I looked! Nonetheless, I couldn’t have been more thrilled to get these up-close-and-personal looks at one of Montana’s most uncommon species.
Sage Thrashers were noticeably more elusive than only a month earlier, but this one did pose nicely on a fencepost along Bannack Bench Road.
You may be wondering just where Gray Flycatchers can be found in Montana. That itself is a fascinating story, because they apparently arrived in our state only recently. The first official record occurred in 1999, and Jeff believes that the birds may only have reached the Treasure State as part of an expansion northward from the Great Basin that occurred in the 1970s. Their Montana strongholds are in Beaverhead and Carbon counties (see post Bear Canyon—Montana’s “Tropical Birding” Paradise), but it takes careful observation and listening to distinguish the birds from almost identical-looking Dusky Flycatchers. The fact that the birds are so restricted here in Montana, though, points out how important it is that we protect our fragile sagebrush communities. It also underscores the great value of the work that Montana Bird Advocacy is conducting, because only by understanding the biology of the Gray Flycatcher and other sagebrush species can we know how to protect them.

Confession: Despite the title of this blog, the the main purpose of last weekend was not to find Green-tailed Towhees; it was to learn about a wonderful study of Gray Flycatchers with biologists Jeff Marks and Nate Kohler. However, as I set out Saturday morning, defiant of the grim weather forecast for the next day, I did have a secondary mission in mind—to find and visit with some of the birds in the arid southwest corner of the state. Over the years, these sagebrush areas, from Bear Canyon (see Bear Canyon—Montana’s “Tropical Birding” Paradise) all the way west to Beaverhead County, had become some of my favorite parts of Montana. I credit that partly to my own childhood living in the dry chaparral country of southern California, but I also just love the ecosystems and birds in this part of Montana. I’d have trouble calling myself a real birder if I didn’t get down there at least once each year.
Since you’re pressing me on the issue, I also had a third objective for this trip—to move closer to breaking my all-time one-year species record. The record belonged to 2017, when our family traveled to Ecuador and Peru and I recorded a total of 527 species for the year. This year, thanks to last-minute invitations to Colombia (see THIS POST) and Texas (see THAT POST) I unexpectedly found myself at 498 species—perilously close to setting a new record. That task loomed more difficult than it might appear since once spring migration has passed and breeding season gets underway, it becomes much more difficult to find new species. Still, a trip to the southwest part of Montana promised to nudge me closer to this new goal, and my first target was one of the state’s coolest birds: Green-tailed Towhee.
On Braden’s advice, my first real birding stops of the trip were along the Jefferson River before Lewis & Clark Caverns.
Green-tailed Towhees winter in the American Southwest and Mexico, but generally breed in the the Great Basin region of the West, including southern Montana. Though the birds are not strictly rare, I could count the number of times I had ever seen one, and I felt eager for another GTTO encounter. To find this bizarre, poorly understood beauty, I hit I-90 at dawn and steered toward Lewis and Clark Caverns, two-and-a-half hours to the east. To entertain me along the way, I had checked out an audio version of Eat, Pray, Love, a book that invites all kinds of snarky comments but, I found, actually proved moderately amusing. On Braden’s advice, I pulled over alongside the road leading to the caverns and was rewarded with a wonderful assortment of river and cliff birds including Rock Wren, Lazuli Buntings, and White-throated Swifts. Once inside Lewis and Clark Caverns State Park itself, I focused on finding Green-tailed Towhees.
While Lewis & Clark Caverns did not give up its Green-tailed Towhees, I did get nice looks at a Rock Wren and Lark Sparrow.A Lark Sparrow in the campground of L&C Caverns State Park.
I struck out. I spent a good hour and a half checking along the road, up around the main parking area, and in the campground. Merlin’s Sound ID picked up a putative GTTO song at one point, but I neither heard nor saw a trace of the bird.
I have to admit that this made me feel like a total failure. I mean, here was my first target bird of the trip, and one that shouldn’t be that hard to find, and I totally “whiffed” on it, as Braden might say. I didn’t plunge into despair exactly, but it definitely put a damper on my mood as I began questioning just what I thought I was doing out here pretending to be a birder! Well, I thought, maybe I’ll have better luck at my next destination.
Which happened to be Birch Creek Road north of Dillon in Beaverhead County. Several years before, Braden and I had found our lifer Thick-billed (formerly McCown’s) Longspur on this road, and once again, the road delivered. I’d driven only a mile before I saw a suspicious dark shape on a fence. I actually didn’t think it was a Thick-billed, but my binoculars revealed otherwise. “Yay!” I exclaimed, feeling the weight of my earlier “whiff” lifting slightly. A few minutes later, I was examining another TBLO when I noticed a large shape sitting in a field about one hundred yards away. “Clearly a hawk,” I thought, “but what kind?” The answer: the best kind, at least for my goals for the trip—a ferruginous hawk. This was another bird I needed for the year and one that isn’t always easy to find in the state.

Digging out the peanut butter sandwich I’d made earlier, I tooled down I-15 for my next destination, Clark Canyon Reservoir. Braden and I had only ever birded here once before, and as near as I recall, we hadn’t found much, so I kept my expectations low. I stopped at one overlook and was surprised to see a Common Loon on the water below, along with a Double-crested Cormorant and a couple of Ring-billed Gulls. Violet-green swallows swirled around me and, as always, they brought a smile.
Snaking around the reservoir, I approached a sign for Horse Prairie Campground and spontaneously swerved left onto a dirt access road. The reason? Tall, healthy-looking sagebrush! Hm, this just might have one of my other target birds for the day. Almost immediately, I saw a really cool bird that had not been on my target list—a Common Nighthawk peacefully chillin’ on the split-rail fence. The bird barely blinked as I fired away with my camera through the car window from only thirty feet away.
The first of three Common Nighthawks I spotted chilling on the wooden fence leading down to Horse Prairie Campground.
Creeping slowly forward, I heard a song I didn’t recognize—which was no great surprise in itself, but I did have a guess of what it was. Sound ID confirmed it: Brewer’s Sparrow! This bird loves healthy sagebrush and makes up for the world’s dullest plumage with a vigorous song that bewitches any birdwatcher who hears it. A few moments later, one even sat still long enough for a decent photo. Check. Another target bird—but not the one I expected to find here!
One of Montana’s drabbest birds, the Brewer’s Sparrow has an enchanting song.
I kept driving slowly toward the campground and spotted a medium-sized, slender bird up ahead. Wishfully, I thought it might be a Say’s Phoebe—another bird I happened to need for my year list—but it flew off before I got close. As I pulled into the campground, though, two brownish birds were chasing each other around. I assumed they were robins, but when one landed on a “Day Use Only” sign, I realized with a start that it was exactly the bird I had hoped to find here—a Sage Thrasher!
Sage Thrashers are so flighty that seeing one on a sign was about the last thing I expected!
Braden and I have never met a thrasher we didn’t like, but Sage Thrashers hold a special place in our birding hearts. For one, they’re the world’s smallest thrashers—which is why I mistook them for robins or phoebes. For another, they are charismatic songsters and often are the most common bird you see in sage country. As I sat in the car, in fact, I counted three more Sage Thrashers around me. Whoo-Hoo!
One of our favorite Montana birds, Sage Thrashers seemed to be everywhere I looked this afternoon.
Later, on the road where I was to meet up with Jeff Marks and Nate Kohler, I encountered seven more Sage Thrashers! It was a veritable thrasher party—by far the best experience I had ever had with these good-looking birds.
Unfortunately, the next morning, heavy rain and spitting snow kept me from seeing Gray Flycatchers with Jeff and Nate. More on that in another post. Almost as bad, I began the drive home without a Green-tailed Towhee under my belt and no expectations of seeing one. But bless Nate Kohler’s heart. He told me about a canyon I should check out on the way home. It was still raining when I got there, but I drove slowly and stopped frequently, listening and watching. Lazuli Buntings chattered everywhere and I saw a good variety of birds—but no towhee. Finally, I put on my raincoat, got out of the car and played a Green-tailed Towhee song. Almost immediately, a small shape darted up out of the sagebrush—the bird I was looking for! Not only that, it held still long enough for a photo—but the story hadn’t quite finished.
I worked hard for this Green-tailed Towhee—only to find that it wasn’t a year bird after all!
Once I got home and posted all of my checklists for the trip, I was surprised that eBird hadn’t added GTTO to my year list. What’s going on? I thought, and did a quick search to see if I had somehow seen one down in Texas and forgotten about it. Nope. What I did forget was the rare vagrant GTTO I had seen in Victoria, BC during Amy’s and my January trip (see Birding Victoria, BC)! So this one was not a year bird after all, but still a lot of fun to see. Meanwhile, my year list swelled to 503 species thanks to the Thick-billed Longspur, Ferruginous Hawk, Brewer’s Sparrow, Sage Thrasher, and a Prairie Falcon I had spotted the afternoon before. Not exactly the trip I expected, but one I already cherished.
The state of Maine can be simplified to four things: lobster, moose, blueberries, and puffins (with Dunkin Donuts as a runner-up). During the four years I’d spent going to school in the state, I’d eaten lobster rolls, visited blueberry bogs, and tried my hardest to find a moose, a quest that would continue later this week. Through no fault of my own, I had never even tried to see a puffin and the reason was simple—my school year did not overlap with the Atlantic Puffin school year. This year, however, was different. I was actually still in the state of Maine as puffins were arriving at their breeding colonies, and was not going to miss my last chance to see these iconic seabirds. So, on May 14th, I boarded a large boat in Bar Harbor and took my seat in the cabin, binoculars and camera ready.
Unlike previous boat rides I’d taken to see birds, this cruise was relaxed and family-friendly. About two hundred people crowded the deck, many of whom were just as interested in the Bald Eagles and American Herring Gulls circling above the harbor as the prospect of seeing any alcids (Alcidae is the family of birds that includes puffins, murres, auks, and guillemots). Over the intercom, a very knowledgeable guide spouted off a non-stop stream of facts about the islands, lighthouses, and wildlife of the area as we headed for Egg Rock, a sparse strip of land just barely visible to tourists standing onshore in Bar Harbor. With the coastline of Acadia National Park to our right, we slowed as we approached the island.
This Common Murre was the only one I saw the whole boat ride. While this species hasn’t yet started nesting at Petit Manan, the ornithologists are hopeful that they will soon!
Egg Rock did not have a puffin colony—it was too close to shore for that. What it did have were colonies of several other species of seabirds. Gulls dominated the island, mostly Herring with scattered numbers of Great Black-backed Gulls mixed in, their charcoal backs sticking out amongst the sea of gray. Cormorants patrolled the southern side of the island, standing tall like gargoyles on the rocks. And in the waters lapping up against the side of the island I saw my first alcids—Black Guillemots! Although guillemots, which are black with white wing patches in the summer and white with black wing patches in the winter, are in the same bird family as Atlantic Puffins, they are far easier to see in Maine. Not only do they breed right on the coast during the warm months, they also stay for the winter—something that the puffins do not do. That’s one of the reasons why I’d never seen puffins here during my time at the University of Maine: From August to April, these birds stay as far from shore as possible, floating around somewhere in the North Atlantic.
After circling Egg Rock to look at the seabird colonies, as well as the dozens of Harbor and Gray Seals lounging on the rocks, the boat picked up speed and headed out to sea. While we never lost sight of the coastline, it grew hazier and hazier until eventually, a new island appeared on the horizon: Petit Manan. The first thing I noticed about Petit Manan were the buildings. Many islands off the coast of Maine had lighthouses, built during centuries past to help steer ships into harbors. As recently as the late 1900s, lighthouse keepers and their families lived on the islands and maintained the lighthouses, although by now many of the keepers had left, likely because boats had better forms of navigation at their disposal. The houses they left behind had been taken over by people working a very different type of job.
The Lighthouse on Petit Manan Island.
Both Egg Rock and Petit Manan are part of a large reserve known as Maine Coastal Islands National Wildlife Refuge. Every summer, dozens of wildlife technicians head out to these islands to spend weeks and months working with the birds that live there. On some islands, like Petit Manan, this work includes Atlantic Puffins, but it also includes monitoring and conservation of other species like Common, Arctic, and Roseate Terns, Common Murres, Black Guillemots, Razorbills, Common Eiders, and Leach’s Storm-petrels. Several of my peers at the University of Maine worked for Maine Coastal Islands and would be heading out to their assigned locations within the next few weeks.
I began to make out large rafts of birds next to the island as our boat approached, and was delighted to spot football-sized alcids with rainbow bills taking off in front of us. I raised my binoculars and smiled—these were the first Atlantic Puffins I’d seen in seven years, since 2018 when I’d been lucky enough to visit Iceland with my grandparents (see my post “All About Alcids”). The birds lounged in the water close to the rocks, and our guide told us that many of them had likely just returned for the summer from their mysterious marine wintering grounds. I counted ninety or so during our half hour stay at Petit Manan.
A raft of Atlantic Puffins and Razorbills!
The puffins weren’t alone. Black Guillemots were here, too, as were a couple dozen Razorbills, another gorgeous black-and-white alcid named after the unique shape and decoration of its beak. I spotted a single Common Murre amongst their ranks, my fourth alcid of the day and a species that had not yet attempted to nest at Petit Manan—but scientists were optimistic! A dozen or so Common Terns circled the island loftily, letting out loud “kyeeeer” calls to notify everyone who was really in charge here. In a few weeks, the numbers of terns would swell into the hundreds, and include Arctic as well as Common. Terns were the aggressive defenders of islands, and would dive-bomb anything they perceived as a threat, including people. I remembered one walk in Iceland when we were asked to hold a tall, wooden stick so the Arctic Terns there would target that instead of our heads!
These birds are the reason that so many alcids nest at Petit Manan. The huge tern colony on this and other islands provide safety for the puffins from predators like gulls and Peregrine Falcons that might otherwise raid their nests. Of course, the biologists working for Maine Coastal Islands NWR were also there to aid these species and chase predators off the island. It hadn’t always been that way, unfortunately.
Common Terns nest in huge, aggressive colonies along the Maine coast!
A hundred years ago, feathered hats were all the rage in cities across the east coast of North America. The demand for white feathers meant that large numbers of terns, gulls, and egrets were harvested—to the extent that these species declined dramatically across much of the country. With no terns to protect them, puffins nesting in Maine were faced with higher predation, but not just from other birds. Rampant collection of eggs and puffin meat also plagued many of Maine’s islands, leading to a dramatic decrease in this species down to just two tiny colonies. Sadly, it was looking like the Atlantic Puffin would join the ranks of the Great Auk and Labrador Duck in Maine’s list of extinct birds.
Thankfully, ornithologists and bird-lovers alike noticed how much environmental damage was being caused by these practices and stepped in. Groups like Audubon formed and began lobbying for the protection of birds, eventually leading to the passing of the Migratory Bird Treaty Act of 1918. And in 1973, Audubon launched Project Puffin. Scientists were sent out to islands equipped with broadcasting equipment and decoys, as well as a small number of puffin chicks donated from colonies in Canada. Step one was the rearing of chicks on islands that had previously been occupied by puffin colonies; step two meant attracting terns back to the islands. Finally, with their defenders back in place, Atlantic Puffins began returning to many of the islands they’d previously been extirpated from. They now occupy six colonies in Maine.
Today, Atlantic Puffins are doing well, but are still being monitored very carefully. Puffins feed on fish that thrive in deep, cold water. That’s why the species only nests on the outermost islands in Maine. Our guide told us, “Puffins would lay their eggs in the ocean if they could.” Unfortunately, the Gulf of Maine is warming faster than any other body of water in the world, and this means that puffins are having to travel farther and farther out to sea to obtain their prey items of choice. During particularly warm years, puffins have switched their selected prey entirely to other species. Many of these other species of fish, which are brought back to their chicks on Petit Manan and other islands, differ in their size and the toughness of their skin. Often puffin chicks cannot eat them, and will starve even when food is sitting right there.
The man-made burrows where puffins nest on Petit Manan!
The good news is that there are many, many people keeping an eye on these birds, doing their best to keep their numbers high. Last year was an especially good year for the species, so optimism is in the air. I felt cautiously hopeful for the future of this species as the Bar Harbor Puffin Tour headed back to shore, content with the pictures and new memories I’d experienced with this iconic Maine species.
Today, FSB kicks off Braden’s accounts of his truly remarkable spring birding trip from Maine to Montana. This adventure would take him to an astonishing variety of habitats most of us never get to experience. Along the way, he would drive 5,000 miles, visit nine states and provinces, and record 264 bird species, seven of them lifers. He begins this series with a visit to Maine’s arguably wildest and most inaccessible county: Aroostook.
Twenty-four hours after walking across the stage of the Cross Insurance Center in Bangor and receiving my college diploma, I was alone in a tent in Northern Maine. I’d gone to school in the state for four years, but never experienced it in the summertime, those three months when Maine is at its best. Now, with an abundance of time, I could leisurely make my way back to Montana instead of the six-day dash I’d done across the country last August. Because of this distant deadline, I’d arranged to spend a week in Maine birding and exploring following my graduation, and there was no better place to start than with one of the two counties I’d never visited: Aroostook County.
A Cedar Bog up in Aroostook County! This one shimmied with Palm and Magnolia Warblers.
Known simply as “The County” to locals, Aroostook is by far the largest and least populated part of Maine. The County contains a large portion of the state’s agriculture, mostly located on its eastern flank, whereas the rest is coniferous forest. Aroostook’s high latitude and cooler climate create a haven for many boreal species of birds that have receded from their more southerly haunts because of warming and excessive logging that promotes regrowth of a different, unsuitable habitat. This northern conifer forest is also a hotspot for the primary topic of my dad’s previous post: warblers.
Warblers, in fact, were a major factor in my decision about where to go to school. I wanted to go to college somewhere where I could see as many warblers as possible, and Maine fit that bill perfectly. With almost thirty species of breeding warblers (nearly triple what Montana, a state twice the size, has) there is no better place to be, and that is especially true of Aroostook County, where most of them could be found. Lying in bed the night of Monday, May 12th, I felt nervous. It was still fairly early as far as migration goes. What if the birds weren’t here yet?
This was my camping spot in Aroostook County, on a backroad in northern Maine!
On Tuesday, May 13th, my worries were settled when I woke up to the sound of a Nashville Warbler singing above my tent. I dressed as quickly as I could and set off down the logging road I’d driven in on, my ears receptive to any and all of the birds sounding off in the surrounding woods. Every level of the forest had songsters belting out their tunes: Ovenbirds from the ground, Black-and-white Warblers from spruce trunks, Magnolia Warblers from ten-year-old firs and Yellow-rumped Warblers from high in the canopy. Present in lower numbers were species like Blackburnian Warblers, Black-throated Blue Warblers, and American Redstarts, all likely early representatives of their species, most of which were still farther south, booking it north.

I was especially excited about the two Cape May Warblers. While I’d seen a fair number of Cape Mays before, I’d rarely seen them in their breeding colors and I’d never heard them sing before. This is because of their distributions. While I’d encountered many of the East Coast warblers on their breeding grounds during my time in Pennsylvania, I was hundreds of miles too far south for Cape Mays, which use contiguous spruce-fir forest and are mostly confined to Canada. These warblers (which are named after Cape May, New Jersey, where they neither breed nor spend the winter) are particularly dependent on an insect known as spruce budworm. Budworms are spruce parasites, and their populations are cyclical. During outbreak years the insect infects and ravages thousands of acres of spruce trees before the population crashes. Cape May Warblers, Bay-breasted Warblers, and Evening Grosbeaks, therefore, all have populations that rise and fall with the populations of this insect.
A “Myrtle” Yellow-rumped Warbler, which is the subspecies that lives on the East Coast!
Besides agriculture, the main industry in Aroostook County is logging, and understandably, the logging industry is not the biggest fan of an insect that defoliates thousands of acres of their crop. Unfortunately, the industry’s historical response to spruce budworm outbreaks (which, remember, are ecologically “normal” and important for the birds dependent on them) has been to clear-cut hundreds of hectares of infected forest. Spruce-fir forest is a mature ecosystem that takes centuries to develop, however, and the forest that grows back after these clearcuts is not coniferous but deciduous. This is a major reason why many spruce budworm-specialists, like Cape May Warbler, and many other birds found in boreal forests, like Canada Jays and Black-backed Woodpeckers, have retreated from much of southern Maine in the last hundred or so years. Their habitat has simply disappeared.
I saw evidence of this as I birded The County. Sure, there was a lot of seemingly healthy spruce habitat. There were also massive empty lots, covered in nothing but slash and debris. The forests were filled with birds, while the lots had almost none. It almost seemed apocalyptic. At least the empty lots provided good views of Mt. Katahdin, Maine’s highest peak, rising in the distance.
Again, though, the forests DID have birds, and not just warblers. Many migrants had not yet arrived (namely the flycatchers, of which I saw very few), but I recorded dozens of Ruby- and Golden-crowned Kinglets, Blue-headed Vireos, and Winter Wrens. Ruffed Grouse drummed from wet thickets, Hermit Thrushes foraged in the road, and I even got to see an American Goshawk bomb overhead at a million miles per hour, chasing something or perhaps just trying to give me as least satisfying a look as possible. In the evening, a walk along a side road yielded incredible, up-close views of Canada Jays, or “Whiskeyjacks” as they are known colloquially. These subtle, white-and-gray corvids landed in the trees less than five feet from me, curiously searching for insects while paying me no mind.

After a night and a day spent in The County, I headed back south to investigate the other corners of Maine I had yet to explore. Stay tuned!
