Braden’s Maine to Montana Birdventure, Part 1: A Day in “The County”

1 Reply

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.

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!

Birding the Burn 2025

In many ways, my own birding journey began with my book Fire Birds: Valuing Natural Wildfires and Burned Forests. That’s when my birding mentor, UM Professor Dick Hutto, showed me the critical importance of burned forests and the spectacular birds that colonize them. It’s also when Braden and I began birding avidly. Since then, we have explored burned forests many times and they have become some of our favorite places to bird. Last week, we were excited to check out one of our area’s newest burns, last year’s Miller Creek fire area, about an hour from our house. To reach it, we headed all the way out Miller Creek and then wound our way up dirt roads until we reached the burn at Holloman Saddle. On the drive, we passed through terrific riparian and conifer habitat, and Braden could pick out Yellow and Orange-crowned Warblers, Swainson’s Thrushes, and Willow Flycatchers through the car window. At about 6,300 feet elevation, we reached the burn, parked, and began exploring.

Researching and writing Fire Birds: Valuing Natural Wildfires and Burned Forests set me firmly on my birding journey—and propelled Braden and me to start birding burned forests. The multiple award-winning book is a great primer for kids and adults on many little-known aspects of forest ecology. To order a copy, click anywhere on this block!

Thanks to Dick’s tutoring, I had some experience sizing up burns and at first, this one didn’t seem ideal. Three birds essential to “opening up” a burned forest are Black-backed, American Three-toed, and Hairy Woodpeckers. These birds hunt wood-boring beetle grubs in the newly-charred forest and along the way, drill out cavities essential for other cavity-nesting birds. But Dick’s research had shown that Black-backed Woodpeckers need larger-diameter trees to nest in, and the forest that greeted us now mainly seemed full of smaller-diameter trees. I also saw stumps where larger trees had already been removed—another huge problem in human (mis)management of burns.

Through decades of well-intentioned Smokey Bear messaging, we have all been taught that all fires are bad, bad, bad. Even when a natural fire does occur, the forestry Powers That Be have taught us that humans must somehow “save” a burn by salvage logging it. For those unfamiliar with it, salvage logging involves going into a burn and removing trees that retain commercial value. The problem? These trees are exactly the larger-diameter trees that woodpeckers need to drill out their homes and, in the process, provide homes for dozens of other animal species. Salvage logging also often severely compacts forest soils and removes the seed sources (cones of burned trees) needed for the forest to regrow. This means that we now have to pay people to replant the burn site—when the forest was already perfectly equipped to replant itself.

Left to their own devices—i.e. without “salvage logging”—most burned forests recover quickly—and with a much greater variety of plant and animal life than before.

Nonetheless, shortly after Braden and I began walking, we heard the distinctive drumming of either an American Three-toed or Black-backed Woodpecker. These can be distinguished from other woodpeckers because the drumming noticeably slows at the end. To find out which bird was drumming now, we began making our way down a steep hillside toward some larger trees, but the burned ground proved very crunchy and we may have spooked our quarry before we got eyes on it. Disappointed, we climbed back up to the road, and continued walking. Fortunately, the forest around us sang and flitted with bird life.

Almost immediately, we began seeing Mountain Bluebirds, one of Montana’s most spectacular species. MOBLs are well-known “fire birds” and their vivid blue plumage looks especially striking against the blackened trunks of a burned forest. Today, we saw these birds everywhere. During our three-mile walk, Braden recorded seven of them, but we both agreed we probably undercounted.

By popular consensus, Mountain Bluebirds are the most stunning “fire birds” you’ll find in burned forests. However, another common fire bird, Western Tanager, might challenge that opinion. Did you know that bluebirds are thrushes? They are relatives of at least four other popular Montana thrushes: American Robin, Swainson’s Thrush, Varied Thrush, and Townsend’s Solitaire.

Suddenly, a large shape took off from beside the road and spread its wings as it glided down into the woods. “Dusky Grouse!” Braden exclaimed. It was one of the birds he most wanted to see since arriving back in Montana the previous week. Hoping for a better look, we crept down after the bird and, sure enough, espied it sitting quietly in the shadows. We enjoyed it through our binoculars for five minutes and then slipped away, leaving it in peace.

Before heading out, Braden told me, “I really want to see a Dusky Grouse.” This one obliged perfectly—and it was the first we’d ever seen in a burned forest.

Except for the mystery woodpecker that had drummed earlier, we had not heard a trace of other woodpeckers, but what we did hear was astonishing: wood-boring beetle larvae actually munching away inside of the dead tree trunks! I’d been told that one could hear these, but with my crummy hearing, I didn’t believe that I ever would. Sure enough, in several places, we listened to these big juicy grubs take noisy bites out of the wood!

Score! While we watched, this Hairy Woodpecker extracted a juicy beetle grub from a dead tree.

Finally, we also heard tapping on a large tree ahead. Braden got his eyes on it first. “It’s an American Three-toed,” he exulted. We could tell it was a female by the lack of a yellow crown, and we settled in to watch this amazing bird. It was working its way down the trunk, flaking away burned bark, presumably to check for insects hiding underneath. Once in a while, it stopped and really began pounding away after a beetle deeper inside the wood. It sounded like someone driving nails into cement!

Even female American Three-toed Woodpeckers can be distinguished from Black-backed Woodpeckers by having some streaky white on their backs—though not as much as on Hairy Woodpeckers (compare with previous photo).

As we continued our walk, we also saw Hairy Woodpeckers and another three-toed, this one a male. Woodpeckers, though, were just some of the birds making use of the burn. We got great looks at Townsend’s Solitaires, Red Crossbills, American Robins, Dark-eyed Juncos, Yellow-rumped Warblers, and Chipping Sparrows, and heard both Red- and White-breasted Nuthatches. Most of these are classic “burn birds” and we felt exhilarated to see them.

Though we didn’t get eyes on one in the burn, we did hear a White-breasted Nuthatch—and saw this one the day before up nearby Pattee Canyon.

At a couple of places, unburned green scrubby areas abutted the fire boundary, and it was fun to see birds dash from these green protected areas into the burn for quick meals or nesting materials before dashing back to safety. Many birds, in fact, love to “set up shop” at the boundaries of such two contrasting habitats.

We never did find a Black-backed Woodpecker, but that did little to detract from yet another great birding outing. We vowed to return to this spot the next few years, hoping that no one would move in to “save” this precious forest that didn’t need saving. On the drive down, we also stopped at some of the lower riparian areas for great “listens” at MacGillivray’s, Orange-crowned, and Yellow Warblers along with our favorite empid species, Willow Flycatchers. Amid the current chaos of the world, our burn bird outing offered a fun, revitalizing—and yes, inspiring—break. If you’re lucky enough to have a burned forest near you, we hope you’ll check it out.

We can’t prove it, but it seems to be a really good year for Orange-crowned Warblers—not always the easiest birds to see in Montana.

Habitats of Africa: A Field Guide for Birders, Naturalists, and Ecologists (Book Review)

I’m excited to be heading off to Texas in a few days, to promote my book Birding for Boomers, but also to squeeze in a few days of birding. Before I go, I want to share an exciting new book that will interest anyone who has ever dreamed about visiting Africa. Braden loved a previous book, Habitats of the World, by two of the co-authors, and this follow-up is also full of fascinating facts and insights. Oh, and in case you missed it, you’ll want to read last week’s outstanding guest post by Roger Kohn, “Cock-of-the-Rock Extravaganza—with Video!” Enjoy!

When I first opened my review copy of Habitats of Africa, I thought, “How on earth did the authors put together such a comprehensive guide to such a vast and ecologically diverse continent?” I next wondered how, as a reader, I might possibly absorb the immense amount of information packed into this handsome volume. The answer to the first question is that all three authors have worked as professional nature guides, with extensive experience in Africa. As for the second? I could only answer that by diving in.

Habitats of Africa: A Field Guide for Birders, Naturalists, and Ecologists by Ken Behrens, Keith, Barnes, and Iain Campbell (Princeton University Press)

The table of contents reveals that Habitats of Africa covers an astonishing seventy-plus different habitats, and honestly, that alone could be overwhelming to the beginning reader. The TOC, though, also provides good clues for how the book is arranged and is therefore worth a few moments of time.

Habitats are organized under a dozen headings, ranging from “Deserts and Arid Lands” and “Warm Humid Broadleaf Forests” to “Savannas” and “Saline Habitats.” The first habitat I read was the Maghreb fir and cedar forest, one of four habitats listed under the “Conifers” heading. I probably started with this one because I don’t usually think about conifer forests growing in Africa. They do, of course, but their ranges are extremely limited, and I wanted to know more about them.

Even those who have never visited Africa easily recognize many of the continent’s distinctive habitats such as this acacia-clad savanna my wife Amy and I observed on our trip to Ethiopia in 2005. This is one of eight distinct kinds of savannas explained in Habitats of Africa.

The listing began with a nice map of where these forests can be found, and then followed with a concise but revealing description of the forest itself. Surprising phrases kept leaping out at me: “Atlas Cedar”, “clusters of oaks”, “winter snowpack”. I mean, where was I, anyway? This sounded more like California than Africa. One of the nice things about the book, however, is that it lists similar forest types found elsewhere in Africa and around the world—including the pinyon-juniper woodland of western North America.

Lamentably, Amy and I visited Africa before I became a birder, but I accidentally managed to take a few bird photos with my point-and-shoot camera, including this magnificent African Fish-Eagle.

After the description, the authors include accounts of a habitat’s conservation status, the particular wildlife that can be found there; and its distribution—including specific places to see it. I found the wildlife sections especially well-done because the authors focused on endemic and other high-interest species while not overloading the reader with information. As a birder, for instance, I discovered that the avifauna of the Maghreb fir and cedar forest shares similarities to what I have observed in the Levant and southern Europe (see posts “Winter Birding in Israel, Part II: Valley of the Cranes” and “Birding Barcelona, Part 1: The Urban Core”)—but that there are also different species such as the Levaillant’s Woodpecker and Atlas Flycatcher.

There’s no getting around that the conservation status for most of the habitats is alarming. It’s hard to find a habitat in which humans haven’t made a major impact, especially given Africa’s rapidly-growing human population. In fact, the book includes eight habitats under its “Anthropogenic” heading—those with little of their original ecosystems intact. Although depressing on one hand, this conservation information provides a good picture of what is going on in the continent—trends that are distressingly similar to those experienced in many of the world’s other places, including North America. I also found it interesting to read why some habitats appear to be faring better than others. For instance, of southern Africa’s succulent karoo habitat—a habitat I’d never heard of—the authors write, “With limited agricultural potential and not much grass, the land in this biome is not highly sought after for human activity, but there has beeen significant sheep grazing and subsequent erosion.”

Ethiopia’s burgeoning population and pervasive poverty force livestock owners to illegally graze, even in places such as Bale National Park, one of the last strongholds of the Ethiopian Wolf.

The problem with reading about one habitat, however, is that it immediately made me curious to learn about others. The Maghreb fir and cedar forest discussion, for instance, mentioned that the forest peters out on the southern mountain slopes draining into the Sahara. “But what’s the Sahara really like?” I wondered, so I soon found myself reading up on one of the world’s most inhospitable places, the Saharan reg desert. This is a place that often receives less than one inch of rainfall each year—and where places can go years without seeing a drop. Yet, life persists here. Although much of the large megafauna has been hunted out, fascinating animals such as sand cats and fennec foxes survive, along with an incredible collection of small mammals and reptiles. This is a good place to mention that the book is filled with outstanding photos of the habitats and their various life forms, and in this chapter a photo of Cream-colored Courser caught my eye. Why? Because it looked almost identical to the Mountain Plovers we have in the arid West!

Amy and I were fortunate to see Ethiopian wolves in one of their last strongholds, a high-altitude habitat called afroparamo in Bale National Park. Already by our visit in 2005, grazing in the park (see previous photo) threatened the outlook for the wolves and the giant mole rats that serve as one of their major prey.

That said, one thing the book showed me is that, although similarities can be found between African and other world habitats, many of the ecosystems in Africa are unique—especially if you compare them to North America. And that can have a strange impact on a reader.

If you have any doubts about the uniqueness of many of Africa’s ecosystems, all you have to do is look at this lobelia tree in Ethiopia’s Bale National Park. The trees reminded me of Joshua trees in the American Southwest, and I can’t help thinking that the two trees might represent a striking case of convergent evolution.

I have only ever been to Africa once, during a school visit to Ethiopia in 2005. What’s more, I thought it unlikely I would ever have a chance to visit again. As I read through Habitats of Africa, however, I kept thinking, “Oh, I want to see that,” and “I want to go there.” It doesn’t mean I will get to, but reading this book may be the next best thing. More than all of the nature documentaries I’ve watched, this volume has given me a plausible idea of the incredible diversity of places and nature that can be seen there. As a birder in particular, it’s also given me a much better idea of the birds that I especially would like to see. It’s a stretch to call the book casual reading, but for anyone interested in nature, or planning their own trip to Africa, it is a well worth your time. If I ever get a chance to return to Africa, you can bet that I’ll be spending even more time with this impressive publication.

Note: Along with the extensive photographs and distribution maps, Habitats of Africa includes a wealth of climate charts, profile sketches, and topical sidebars that enhance the reader’s understanding of each habitat.
