Arguably herring are the base of the entire food chain in Southeast Alaska. They provide food for whales, salmon, seals, sealions, birds, and halibut with their bodies and with their eggs. For centuries humans have relied on the abundance of herring to provide for their families in the spring. In Hoonah, Alaska the return of herring marks a change in the a season and a bounty of fresh eggs brings a welcome smile to the elders and community members that receive them. However, in recent years the herring run has not bee large in Hoonah although anecdotally (and a bit facetiously) you could “walk across their backs to Pitt Island” only a couple decades ago. Ocean changes, over fishing, and habitat loss have all contributed to decreasing herring returns and fewer spawning fish in recent years. This knowledge made me feel particularly fortunate to get to see herring spawning in Hoonah and watch the harshness of nature unfold before my eyes as Bald Eagle scooped the silvery fish from the ocean.
Spawning herring rely on seaweed and objects in the water to glue their eggs to. Spawning females mix with males and each emit eggs and roe into the water. A sure sign that herring are spawning is a milky, blue water that combines the colors of the ocean and the white of the roe. The need to stick their eggs to seaweed brings the herring close to shore and thus susceptible to predation. As I walked near Cannery Point in Hoonah, Alaska over 30 eagles (a mix of juveniles and adults) lined up on the beach. The color of the water and brilliant flashes of silver near the shore left little doubt on what they were feeding on!
A string of eagles wait for spawning herring at the beach.
Trial and Error
One of the first things I noticed was the juvenile eagles were watching the adults very closely. They knew they had a lot to learn, and there was no doubt after several minutes of watching that the adults were much more efficient at catching the herring. Most of the adults would launch from the beach, strafe their talons on the water’s surface and come up with one or two herring. Some eagles opted for a higher vantage point and flew in from the trees on the embankment. Another strategy was to simply stand on a rock or in the water and hope to catch one in without flapping a wing. All of these strategies produced herring for the eagles and the juveniles mimicked them perfectly.
Meals on the Wing
Even though there was an abundance of herring one strategy of some eagles was to steal from those that were successful. The fierce competition from other birds forced successful eagles to eat very quickly and on the wing. Almost all of the eagles would transfer the herring to their beaks and then orient the fish head first before finally swallowing it hole. This occurred in just a few seconds to remove any chance of pestering, marauding eagles from stealing their catch. I did get to watch once instance where an eagle successfully scooped two herring at once, but did not eat them on the wing. Immediately three other eagles (2 adults and a juvenile) put up chase resulting in the eagle dropping one herring to get rid of the pestilence following it.
Two eagles settle a small squabble over who gets some beach space.
Repetition, Repetition, Repetition
It was incredible to watch the eagles feed on the herring and learn from their behaviors, but as a photographer I was grateful for the frequent and repeated attempts by the eagles to capture herring. I had the opportunity to tinker with camera settings and capture a lot of shots that are high quality and showcase the slice of foodweb that I was only a spectator to.
In the South Pacific, the islands of Hawaii emerge like green jewels from the vast ocean. For many tourists these islands offer beaches and relaxation and forested hikes. Throughout these habitats are dozens of species of birds that have evolved on the island and live nowhere else in the world. Known as “endemic” species they contribute to the biodiversity and beauty of the place and also to the allure of the islands to birders. There are also a multitude of stunning species that have been introduced from foreign countries through Hawaii’s long history of travelers and agriculture. Last there are the migrants – birds that live in Hawaii each winter and feed in its rich forests.
Birding Hawaii for the first time is certain to add many species to your “life list” and after a week of casual birding my wife and I were thrilled at the chance to see some of these winged wonders.
Endemic species are often highly evolved to fulfill a certain niche. This means they often rely on a certain food source or nest in a certain area. They are highly specialized and are susceptible to habitat destruction, climate change, and competition from introduced species. These birds did not evolve with mammalian predators and have felt the pressure of cats and mongoose which came with humans. According to ABCbirds.org, 95 of 142 endemic Hawaiin bird species have gone extinct since human arrival. Of the 44 remaining species, 33 are on the endangered species list and at risk for extinction. These statistics have prompted many studies and efforts at restoration. Hopefully efforts will successfully save some of these beautiful species. Certainly the liklihood of extinction means birding Hawaii now may be your best time to see some of the species before they disappear forever. We only saw several endemic species and hope to pursue these more on our next trip to Hawaii.
Hawaii has a long past of habitat destruction and modification from humans. In the 1830s, the first successful sugar cane plantation was planted in Hawaii and “cane” plantations spread like wildfire from there. For nearly 180 years the cane plantations burned through acres and produced huge amounts of product. In 2016 the last cane plantation shut down. However, that industry, development, military activity, and travelers introduced dozens of birds, plants, insects, and mammals. Many of these birds thrived in the warm and gentle climate and in time competed with the endemic species that lived there. We had an opportunity to see a wide sampling of these species on while birding the Big Island and Oahu.
Of all the migratory species that we observed the Bristle-thighed Curlew was certainly the highlight! Very little is known about the habits of this bird, but they breed in northern Alaska and winter exclusively on islands in the south pacific. It was pretty remarkable to see them walking around the golf course near Kona!

Birding Hawaii made me realize again how connected birds make the world. Regardless of the distance and expanse they have to cover they are able to connect regions like the Bristle-thighed Curlew connects Hawaii and Alaska. I cannot wait for the next time that I bird those gorgeous islands.
In northern Minnesota a chain of bogs and open forest near Sax and Zim are full of winged wonders. This track of land, the Sax Zim Bog, is renowned for its migrants from northern Boreal Forests that flit among the spruces and for the ghostly shapes of owls that drift on silent wings among the tamaracks. Spending time in the bog can provide amazing opportunities to watch these birds and learn about their survival skills in a harsh winter.
A Great Gray Feast
My dad and I arrived at Sax Zim Bog at 7:50 AM. The sun was just coming up in a bright blue sky, but it did not provide much warmth to the -20F day. However, without wind the day was quite pleasant and the conditions were perfect to find active owls. At 8:05 AM we found two active Great Gray Owls. The pair hunted 100 yards apart, perched on short, wooden power poles. In the typical behavior of owls, the closer owl swiveled its head back and forth, gathering the noises of its surroundings. Great Gray Owls are the largest owl in the world and their unique facial disc funnels sound directly into their ears like a satellite dish focuses a signal. This adaptation allows them to be efficient predators able to locate rodents under the snow.
When the owl swiveled its head and focused its gaze I knew that the hunt was on. Soaring silently on a 5-foot wing span the owl plopped down in the snow 30 yard away. Its body was half in the snow and half out, and for 10 seconds it just sat in the snow giving the illusion that it was unsuccessful. But then the owl surged from the snow with a large vole grasped in its talons! I stood in awe at having witnessed the hunt first hand.
Pouncing Northern Hawk Owls
As their name suggest, Northern Hawk Owls are an owl of the far north that migrate south in the winter. Because northern climates do not get much darkness in the summer these unique owls have adapted by hunting at all times of the day. We found our first hawk owl at 1PM, characteristically perched at the very top branches of a dead tree. After watching for awhile the owl zoomed to a perch further in the forest and then another perch even further out. They do this to find new and unsuspecting rodents to munch on.
When we saw the Northern Hawk Owl kill its first vole, I was struck by how much different their approach was than the Great Gray. It took off from a branch and then hovered (stooped) silently above the ground (thanks to modified wing edges that dampen sound) much like a hawk or falcon would do. It rapidly came out of the stoop and crashed to the ground to catch its first dinner. 20 minutes later it exhibited the same behavior. It is amazing to think how many voles the Owls of Sax Zim Bog must kill on a daily, weekly, and yearly basis!
A day at Sax Zim Bog can bring about AMAZING experiences, but please practice ethical photography of the residents that live there. Owls are very susceptible to the unethical practice of baiting. For the safety of the owls, please DO NOT bait them! Also, please give them their space as they make and consume kills and do not stay with an owl too long. Most of theses images were taken with an 800mm lens and thus were taken from a respectful distance. Doing these things will keep the owls safe and ensuring that you have the best day possible observing these amazing animals!
Utqiaġvik (Barrow), Alaska is the furthest north city in the United States, and just a few miles north of that on a small spit of land is Point Barrow where you can go no further north and still be on U.S. soil. At that point, the expanse of the ivory ice of the Beaufort and Chukchi seas stretches in front of you further than the eye can see. Looking south you will see no hills greater than a few feet tall – a tundra so flat that it seems like a wasteland. However, the tundra is fueled by perpetual sunlight for over 65 days each season and becomes an oasis for dozens of species of birds that come from multiple continents. With the flocks of birds come the flocks of birders to watch and observe their beauty and behavior under the midnight sun. We birded from June 16th to the 20th, recorded total 41 species of birds (although I think we missed a few on our final list) and 9 “lifer” birds which we had never seen before.
I realize not all of you reading this article are birders, so you may be wondering, “why would you take the time, hassle, and money to travel to the furthest point in the U.S. just to look at birds”. It’s because the birds are at their very best. You can think of this way : there are always cherry trees in Washington, D.C., and they are very beautiful to look at year around. However, during spring when they are in bloom the common cherry tree is transformed into an incredible spectacle. The birds in Barrow are the same – each is dressed to the nines in order to attract and breed with a female. They also show off behaviors and calls which you will see at no other time of the year.
The first owl we saw was the whitest owl (perhaps even bird) that I’ve ever seen. Typically Snowy Owls have some black in their wings, but this bird was almost sheer white with a few specks of black. The lack of color is indicative of the age of the bird and sex. Males are whiter than females and older birds are whiter than young birds. We can conclude from those two facts that this incredibly beautiful individual is an old, adult male.
“The Eiders” and Other Waterfowl
Eiders are a family of sea-duck with four different species, and a circumpolar distribution. Each of the species is stunningly colored and have incredible plumage and sexual dimorphism (i.e., the males are dressy, the females are plain). Barrow provides relatively easy viewing of all four species of eiders in one place. We found Stellar’s, King, and Spectacled Eiders feeding in shallow ponds in the tundra. Each of them were paired and simply waiting for the snow to melt further, and the tundra to sprout before laying eggs. We observed Common Eider flying over the Chukchi sea on their way to different breeding grounds. Many other species of ducks and geese were found throughout the tundra to compliment the eiders.
Shorebirds in Barrow have their tuxedos on, are wearing Rolexes, and are ready to do whatever it takes to impress their female counterparts. They are a far cry from the drab, brown birds they become any other time of the year. The breeding displays vary from puffing out chest feathers, strutting with quivering wingtips, or taking to the air and flying high for all of the females to see. While we were there, the most vocal were the Pectoral Sandpipers. Male birds flew over their territories with chests feathers puffed out and made an indescribable-in-words galunking sound.
There was much more to see than just the breeding behavior of the shorebirds, and probably the most entertaining of these small birds were the phalaropes. Both Red-necked and Red Phalaropes feed by standing in shallow water and spinning in circles to stir up the bottom with their feet. They push their bill and head under the water to pick up their unsuspecting and confused prey. Their behavior reminds me of a dog chasing its tale, and its very hard not to smile when watching them.
North of Barrow is Point Barrow. This small spit of land has been used for millennia to capture whales and sea mammals for subsistence by the Iñupiaq people, and I was astounded by the number of Bowhead Whale skulls and bones along the beach (just for the record I 100% support this subsistence and cultural way of life). The bones helped answer some of the questions I had about whale structure and morphology.
Baleen is a key feature of non-predatory whales, but I’ve never quite understood how it was arranged in the mouth. In the jawbones of a couple of whale skulls, I saw that multiple (>50) plates of baleen lay parallel to each other on the left and right side of the mouth. Their arrangement allows the tongue to slide between the plates to push the water out and capture their food.
The many bones along the beach also put into perspective just how huge Bowhead Whales are. Jawbones may reach 13 feet in length, the vertebrae can be 20 inches or more wide, and the ribs can be 10 feet long. These are incredibly huge animals that must have been difficult to capture with seal-skin boats and bone-tipped spears. But somehow, in the face of this immense challenge, that is what the ancient Iñupiaq were able to accomplish.
Across the expanse of the sea-ice were cigar-shaped black specks. Most of the specks turned out to be seals. These seals provide a food source for humans and bears. I believe the most common species we observed were the Spotted Seal, but three other species may are present in the region. Although we scanned the ice pack for Polar Bears, there were none to be found.
In the summer, Barrow is the city that never sleeps. We were amazed at the amount of activity at all hours of the day throughout the community that can be attributed to the never setting sun. 24 hours of daylight ensured that the birds were active and visible during all parts of the day. We “Barrow-ed” our time schedule by staying up until 2AM or later on all of the nights we were in town. After four days we were exhausted, but thrilled to had a glimpse of this incredible area and the birds it holds.
Species list (some likely missing) from June 16 – 20, 2017:
A couple of weekends ago I had the opportunity to tour Glacier Bay National Park with Hoonah’s 5th and 6th grade class. The trip was the culmination of their “Plumes of Glacier Bay” curriculum where they had been studying the species of birds within the park. As an avid birder I was thrilled to bring these 16, rambunctious kids on an ecology trip into the park on the “Dayboat”. The boat travels into the park to pick up travelers and provides an 8.5 hour, 130+ mile cruise to tidewater glaciers with opportunities to view tons of wildlife.
Its not always (one might say rarely) sunny in Glacier Bay. The cold waters and moist air cause rain and fog to form quickly within the park. However, we started out our day under high clouds with small patches of blue sky. Just after launching, we encountered some choppy water in the passage out of Bartlett Cove. Our on-board park ranger, Jenny, explained that the bottom of the ocean had striations in the sediment from the receding glacier that pushed the water up, often making it choppier than the wind would merit. After 45 minutes of cruising at 20 knots, our first stop along the way was at South Marble Island. This small island offers refuge to nesting Black-legged Kittiwakes, Tufted Puffins, and other colonial sea birds looking to nest away from predators. It also has huge haul-outs of Stellars’s Sealions. The gigantic animals that I like to call “sea grizzlies” because of their immense size (up to 2,000 pounds), lay on the rocks in the sunshine like sausages. The dominant males sat with back arched and head erect. Their enormous size compared to the others around them made it easy to see why they were the boss.

Our boat cut through the water past South Marble Island, and we moved up the fjord. As we did, the mountains became more jagged and covered in snow. At the mouth of Glacier Bay most the mountains had been covered ice during the last glacial advance which rounded them off over time, but the terrain became more jagged as we moved past mountain tops untouched by the glaciers. An exception to the jagged mountains was the round, granite dome named “Gloomy Knob”. On that granite dome were well manicured lawns of grass with sporadic cottonwoods growing in the crevices. The lawns were kept short by overwintering Mountain Goats who grazed the pastures. Just after the spring thaw is the best time to watch the goats, and I think we counted 20 of them on Gloomy Knob. Many of them were feeding their kids, and we got some insight into the bonding of goats with their mothers – one made a spectacle by climbing onto its mothers back.
The goats were not the only four-legged mammals on Gloomy Knob. High up in the granite cliffs we spotted a family of four Coastal Brown Bears. They lounged on the rocks, sleeping, perhaps 1,000 feet above our heads. During our passing they roused and moved along the ridgeline. They even passed by a goat on the ledge below them. Although the grizzlies took a look at their potential meal, the Mountain Goat seemed to know it was safe from the predators above, as it never moved a muscle.
Sixty-five miles from where we started in Bartlett Cove we finally reached the end of the park. Marjorie Glacier stood in front of us like icy walls. The glacier face is about 350 feet tall and extends nearly a mile from left to right. In many of the pictures, you can see pin-sized Harbor Seals with their pups on the ice flows to lend the glacier some size perspective. Two times the glacier let go of new ice bergs by “calving”. The roar was like thunder of an approaching storm. The glacier, which is currently 21 miles long, has retracted 65 miles. In 1750, it was responsible for pushing the Huna Tlingit from their homeland. Since the retreat has happened so quickly, there are many studies within the park boundaries to understand how recolonization of rock surfaces occurs. Also, the land around the glacier is springing back up from the weight of the ice in a process known as isostatic rebound. The land rises almost an inch a year which may cause river drainages to change and coast resources like clam beds to come out of the water.
The students gave the whole boat a treat by performing traditional Tlingit songs at the glacier. Their pounding drums mixed with the grandeur of the scenery for a truly memorable end to the day. The trip into Glacier Bay was an incredible introduction to this vast and wild park. I look forward to the day when I return for a more detailed look at its beauty.

Another year come and gone! This year has been nothing short of life-changing. I graduated with my masters in Wildlife from the University of Alaska Fairbanks, moved from the Interior to the incredible Southeast Alaska, married the love of my life, and have a job I love! Life is great, and life has left me less time to blog recently (lack of time compounded by no internet at my house). However, that doesn’t mean that my camera has been sitting picking up dust in the corner. On the contrary I’ve been out photographing the wild beauty of Hoonah and Alaska all year. Some of these images from 2016 have made their way onto Facebook. You can “like ” my page for daily photo updates at www.facebook.com/ianlww. For other images this is the first time they’ve been shown off! Previous year-end recaps have been in different formats such as dividing by month in 2014 and dividing by topic in 2015. This year I’m just going to scrap the text and the give you the top shots 2016 from around Alaska. I hope you enjoy!

What does it mean when one of the least researched and understood marine birds in the Arctic turns up in Duluth, Minnesota 1,500 miles outside of its range? Locally, it ensures a birding rush of in-state and out-of-stater birders eager to see the rare bird, but what does it say about the global status of this unique bird? How can we use its presence to educate ourselves of human impact on the high Arctic? Is the Ivory Gull (Pagophila eburnea) an indicator species of a greater issue in the Arctic? The suspicion that their unprecedented, 80% population decline over the last 20 years may be linked to mercury suggests they are.
Population Free-fall of the Ivory Gull
Ivory Gulls are colonial birds, meaning that large numbers gather into groups to breed. By monitoring the nesting colonies of colonial birds, population trends may be established by researchers. However, surveys for Ivory Gulls were only conducted in 1985 (Thomas and MacDonald, 1987) making it impossible to understand population trends. Compounding the lack of population data, Ivory Gulls are considered to be one one of the least understood marine birds. This is partly due to wintering along the ice pack between Greenland and Labrador ensuring they are not a bird which is in-sight of many people. However, indigenous knowledge has suggested declining populations since the 1980s (Mallory et al. 2003). In light of this, researchers flew surveys of known nesting islands as well as newly found Islands in 2002 and 2003 and found something shocking. The number of nesting Ivory Gulls had declined by 80% since the 1980s (Gilcrest et al. 2005).
Gilcrest et al. (2005) started to hypothesize at alternative reasons for the lack of gulls. They explored the possibility that the Ivory Gulls had simply shifted their nesting locations. However, a significant move is not inline with the known biology of the bird which generally move less than 1-2 kilometers. Food sources of fish and carcasses have remained relatively stable in their study area giving them little reason to move. They noted that Ivory Gulls were not seen flying along the survey paths. It seems that the Ivory Gull was truly dying off.
The Driver of Change
Since the startling revelation of population decline, researchers have been trying to understand why Ivory Gulls are disappearing. It is probable that ice-pack changes and altered forage have contributed to the population decline (Gilchrest et al. 2005), but researchers think a stronger factor is in play . In his interview with the BBC World Service (full interview below) Dr. Alex Bond hypothesizes that mercury is a leading stressor on Ivory Gulls based on findings that levels of mercury have risen 45 -50 times the levels found 130 years ago. There is strong evidence showing mercury levels in the eggs of Ivory Gulls is significantly higher than any other known marine bird. Braun et al. 2006 found that mercury in the eggs of Ivory Gulls were 2.5 times greater than even the next highest species, and were almost 3 times greater the amount which impairs reproductive success. Where is that much mercury coming from? And how exactly might it effect Ivory Gulls?
To understand where the mercury is coming from, its important to know the basics of the mercury cycle. Mercury falls into the oceans from atmosphere pollution originating from coal-fired power plants, or is directly input from Alkali metal processing . There are also natural sources of mercury like volcanic eruptions and “volitilization of the ocean” (USGS 2000). Once deposited in a waterbody, mercury becomes available to marine animals when it is transformed to methylmercury. Once in the that state, it moves up through the food chain into plankton, and then to fish, and finally to top level predators like birds and marine mammals. Levels of mercury grows in organisms through bioaccumulation and biomagnifcation. To clarify that jargon, bioaccumulation means that the older you are, the more mercury you have since it is difficult to get it out your system once ingested. Biomagnification means that if you feed higher on the food chain you gain mercury more quickly. Marine mammals like seals have very, very high levels of mercury due to the effect of both bioaccumulation and biomagnifacation. With that information in mind it is easier to understand why Ivory Gulls accumulate mercury; they scavenge on carcasses of marine mammals and feed on fish which have high levels of mercury. They also have a high metabolic rate and consume more fish (Braun et al. 2006).
To date, the effect of mercury on Ivory Gulls has not been studied, but we can gather clues from looking at other species. Common Loons (Gavia immer) also accumulate high levels of mercury due to eating fish (biomagnification) and having long lives (bioaccumulation). Evers et al. 2008 found a 41% decrease in fledged loon young in parents with >3 micrograms of mercury per gram of tissue compared to those with <1 microgram. They predict total reproductive failure of Common Loons if levels exceed 16.5 micrograms. Based on hundreds of hours of observation, they report that loons with elevated levels of mercury are lethargic and spend significantly less time foraging for food and less time taking care of their young. Each lead to fewer chicks growing to adulthood. It is important to note in their study that mercury levels of a species change throughout their range due to climate, forage, and many other factors. Transferring the lessons of Common loons to Ivory Gulls, variation in mercury levels changes are observed in Canada as well; in general levels of mercury increase from east to west in Canada. Although the effect of mercury on Ivory Gulls has not been directly studied and may effect gulls differently than loons, a good hypothesis for their decline is poor parenting and lethargy due to extraordinarily high levels of mercury. Only future research will help tease out the true effect of mercury on their decline.
When an Ivory Gull shows up in Duluth, Minnesota it is a chance to reflect. Reflect on the beauty of an animal. Reflect on the joy of seeing such a rarity. However, do not miss the opportunity to acknowledge that its prescense is out of the norm of the species and that an unseen driver which we do not fully understand is at play. Reflect on the fact that the impact of humans in a nearly un-inhabited region is undeniable. Human consumption of fossil fuels is depositing mercury into the Arctic at rates which may be directly effecting a species. The Ivory Gull is a red flag, an indicator that things are not right in the Arctic and that we should pay heed to what else may be going wrong that we just have not taken the time to study yet.

The 18+ foot tides of Homer Alaska define life on the seashore. Its consistency and rhythm are the drumbeat of the ocean. During the summer each day, salmon return to the “Fishing Hole” with the incoming and outgoing tide chasing schools of baitfish, only to be chased by fisherman. Shorebirds feed at the tideline and in the exposed rocks which contain many insects and invertebrates in the crevices. Tide pools contained trapped wonders to because observed with curiosity, and which have evolved to survive the temporarily dry conditions. They often closing up, or shrinking under the sand to conserve water. My time in Homer, Alaska was focused around the seashore, fishing, beach combing, birding, and peering into tide pools. These pictures and experiences are both through my lens, and Kassie’s too.
Peer into a tidepool, and what shall you see? Small creatures, shells, or an anemone.
As the tide goes out, large boulders hold water and sea creatures – tide pool!
The tentacles of a green anenome reach for the surface in a a tide pool.
This large, lone, mussel displays one of its unique characterists. The strong, hair fibers of its holdfast which secure it to a a rock.
Within a tidepool I watched this tiny hermit crab discover, and then attempt to pry loose this limpet for dinner. For scale, this tiny limpet is half the size of a dime, and the crab even smaller.
This particular anenome in the tide pool was very striking. Wedged between two rocks, I was able to capture it through the surface of the water!
(1) The sand flats in between the rocks may holder larger treasures….
(2)… like this starfish! This large star fish was 10 – 12 inches across. We moved it to a wetter, and safer tide pool.
This image of a dead clam among the rocks, and surrounded in seaweed seemed to imbibe the whole concept of tidal change to me.
As we walked along the beach a northwestern crow began to dig a hole along the surf line. To our astonishment it jerked out a thin, silvery, and wriggling Sandlance from the bottom of the hole. Hopping forward a bit further the crow did it again, and again. Other crows were doing the same thing, and were apparently highly efficient hunters. I relayed this video (below) to a birding group, and was informed this hunting behavior may be specific to Homer crows. Have a watch, and let me know your guesses on how they locate the eels. I have not a clue!
Our trip had taken us from Fairbanks,Alaska up the Haul Road (Dalton Highway), over Chandlar Shelf, and peaked at Atigun Pass (4,738′). We traversed the valley on the north side of the Brooks Range, and explored as far as Toolik. Although we were on the tundra, we never went far enough to leave the Brooks Range out of sight. Because of the incredible backdrop the mountains provided, I was compelled to place what we observed in their natural habitat. The resulting pictures and galleries provide a slice of diversity of the flowers and birds found on the tundra.
One of the remarkable birds seen during the trip was a bluethroat. These awesome birds are one of a few species which winter in Asia, but breed on the tundra in Alaska. Due to the amount of migration time needed they spend a lot of time on the wing! When we found it with help from another birder, the male bluethroat was displaying in the air and calling out in the voices of many species. Bluethroats are almost perfect mimics, and as it sang out we could hear the calls of redpolls, gray-cheeked thrushes, and swallows in its repertoire. A bluethroat female will find this male attractive if it can mimic enough other birds. The video below captures a few of the calls of this unique and beautiful bird, and shows of its stunning throat!
The northern hawk owl was another great bird of the trip. These raptors are efficient predators and unlike most owls are active during the mornings, evenings, and even during midday. This adaptation arose from the lack of nighttime in the tundra. The hawk owl we found was perched in the dead limbs of a burned black spruce, and actively twisted its head back and forth at every new sound. Suddenly the twisting head stopped, and it fixed its gaze on some unfortunate small animal on the ground. It dove off the branch with tucked wings, swooped low above the shrubs, but then perched again with empty claws. No breakfast this time! The second video below shows the intense stare of this bird.
Northern Hawk Owl Video:
Yellow, purple, pink, white, and red splashes of color were evident all across the tundra. Each color was associated with a pointed, rounded, tall, or stunted flower and stalk. The flowers of the tundra come in many different colors and shapes! Often the species are associated with a particular habitat type. Alpine arnica were found in the higher alpine tundra, arctic poppies in the short tundra, and bell heather tucked into the low pockets of the tussocks. One of the unexpected flowers of the trip were the frigid shooting stars that lined a small stream south of Toolik Field Station. Although I have wanted to see them for years now, I never thought the first time would be on the tundra! The flowers are aptly named, as their unique shape trails behind them as if they fell from the sky.
I am about to sing the unsong of the mosquito because each bite from the armies of flocked, winged, beasts can cause doubt that they serve any purpose but to cause misery. However, during the trip I documented one of the mosquito’s greatest contributions to the ecosystem. In the tundra, bees and butterflies are not as abundant as they are in forested areas, however, as shown above the variety and abundance of flowers have to be pollinated by something! In step the buzzing, nagging, mosquito. Male mosquitoes do not feed on blood, but rather nectar and thus spread pollen. Their hunger ensures that the blooms of the tundra create seeds and propagate for the next year.
By the time we reached Galbraith Lake, North Slope, Alaska, the low light of the solstice sun to the north was casting shadows on the peaks of the Brooks Range, which finally lay to the south of us after hours of driving. Although rain showers had passed through earlier in the day, the lingering clouds were just cotton in the sky, lit to the orange color of hot coils of a stove. Our trip was planned for three days, and our mantra was to have “nowhere to be, and all day to get there”! We observed, absorbed, and enjoyed the birds, flowers, and beauty of the Tundra during solstice. Due to the many photos from the trip, the results will be broken into two chapters, “Solstice, Solitude, Soliloquy”, and “Birds and Blossoms of the Tundra”. I hope you enjoy this first installment!
During the day we drove the Haul Road to various hiking destinations. A creek bed, a bird sighting, or a nice pull-off were all excuses to hike around and check out a new region. Although the road was busy with traveling semi-trucks and tourists, as soon as you walked away from the road the solitude was immediate. Few others hike around on the tundra at this time of the year, and its vast expanse ensures that even if they do, you do not have to see them unless you choose to. Since creek beds offer a natural hiking corridor through and around ankle twisting tundra humps, tussocks, we used them often. The small, bubbling rivers bottoms flowed through rockfields created by spring melts, and were just a fraction of their size during the melt a few weeks prior. However, flow was higher than normal for the time of year, as a snow storm just 10 days earlier fed them from the mountains. I was drawn to the colors and sizes of rocks on the stream beds, and the mountains behind them which birthed the running waters.
At the end of each day we set up camp on the tundra, targeting soft patches of sphagnum moss for our sleeping pads. The mattress companies of the world should take note of the comfort of the tundra – it is unparalleled in soft-yet-supportive sleep. From our camp we took small hikes to check out the local flora and birds. The hikes always brought something new to see and experience. Near one of our camps we discovered this baby longspur (either a Smith’s or Lapland) on the tundra. It perched on the moss in the warm sun, and was likely waiting for food from its parent. Unable to escape, this baby bird’s instinct was to sit as still as possible. I snapped a few shots, and then stepped away so its parents could rejoin and feed it.
As we walked around each night I looked for settings to put up a solstice timelapse. The advantage of a timelapse over a single shot is to show the traveling path of the sun as it reaches the horizon and then curves back into the sky. Over the Brooks Range, being so far north, the sun stayed far above the horizon – it hadn’t dropped below the horizon there for over a month. This was in stark contrast to shooting at Finger Mountain about 15 miles south of the Arctic Circle where the sun just dipped below the curve of the earth. The resulting shots from each location have been fused together, and shown individually below. The lighting of the composite shots, in particular, I believe is very striking. Since each image is made of 8-10 shots over time, each plant has been lit from many angles. Because of this, extreme detail can be seen in each flower in the tundra foreground.
A trip to the Tundra will bring as much to experience as the eye can behold and the brain can perceive. I’m looking forward to the next chapter of birds and blossoms!
