A List of Wilderness Mystery Authors
[image error]
Last week, I talked about my tagline as an Alaska wilderness mystery author and discussed my efforts to find my ideal readers. In other words, I’m looking for readers who enjoy reading wilderness mysteries. When my publisher first tagged me as an Alaska wilderness mystery author, I laughed at the description because I’d never thought of myself as a wilderness mystery author. I use a setting I know and understand in my novels, and this setting happens to be the wilderness of Kodiak Island where I live.
To understand my place in the mystery genre as a wilderness mystery author, I had to find other wilderness mystery authors and see how my books compare to theirs. I’ve found several wilderness mystery authors, but our numbers are minuscule compared to other subsets of the mystery genre. I thought it would be helpful for my blog readers for me to compile a list of the authors I’ve found in the wilderness mystery category. This list is by no means an exhaustive; it is only a beginning. I ask you to add to my list by leaving a comment at the end of this post. I don’t want to exclude any authors, and with your help, I can make my list more complete.
Nevada Barr: The queen of the genre in my opinion. Her first Anna Pigeon mystery was 
published in 1993, and she has since written 18 additional books in the series. Anna is a National Park Ranger. 
Dana Stabenow: An award-winning mystery author from Alaska who writes a series featuring Kate Shugak, an ex-investigator for the Anchorage D.A.
Sue Henry: Another well-known, award-winning Alaskan author whose series features Alaska State Trooper Alex Jensen and dog musher Jessie Arnold.
C.J. Box: Author of the award-winning series starring Wyoming game warden Joe Pickett.
Paul Doiron: His protagonist, Mike Bowditch is a game warden in Maine.
Joseph Heywood: In his series, Grady Service is a wilderness detective with the Department of Natural Resources in the Upper Peninsula of Michigan.
Craig Johnson: His series character, Walt Longmire is the sheriff of Absaroka County in a remote part of Wyoming.
Keith McCafferty: His two main characters, Sherriff Martha Ettinger and fishing guide and part-time detective Sean Stranahan, have a complex relationship throughout this series located near Montana’s Crazy Mountains.
Jessica Speart: Her series features U.S. Fish and Wildlife special agent Rachel Porter who works to uncover the poaching and smuggling of endangered wildlife species.
Pamela Beason: Her wilderness mystery series features wildlife biologist Sam Westin, whose knowledge of wildlife and wilderness survival aide her in her criminal investigations. Sam lives in Washington, but her adventures often take her to other points around the globe.
Kimberli A. Bindschatel: Her protagonist is U.S. Fish and Wildlife Agent Poppy McVie.
Robin Barefield: (I have to include myself on this list!) Her main character, Jane Marcus, is smart and resourceful, but unlike most of the other protagonists on this list, Jane is not comfortable in the wilderness. When Jane finds herself in the wilds of Alaska, she must depend on her wits to survive.
This is my short list. Who have I forgotten? Please list your favorite wilderness mystery authors in the comments section of this post, and I will update my list. In the meantime, start expanding your reading list of wilderness mystery authors by checking out books by some of the authors I have mentioned!

Wilderness Author
[image error]
Lately, I’ve been thinking about what it means to be a wilderness author and why the setting I’ve chosen is so critical to my novels. I naturally like to set my novels in a place I know well, and since I’ve lived in the wilderness for more than 30 years, it’s only logical for me to place my characters in this environment. I understand the challenges of the Kodiak wilderness, respect its tantrums, and love its beauty.
I know not everyone enjoys reading mysteries (crazy as this sounds to me), and of those who like to read mysteries, only a small fraction embrace wilderness mysteries. Mystery novels come in all shapes and sizes. We have cozy mysteries (think Agatha Christie), hard-boiled mysteries, police procedurals, thrillers, and puzzle mysteries to name a few. Except for cozy mysteries which are often set in small villages or towns, a large percentage of mystery novels are set in big cities, whether it’s New York, London, Tokyo, Chicago, L.A., a fictional city or somewhere else. Cities make sense as settings for mysteries because a large number of people live in a relatively small area in cities, and crime is not unusual there. City dwellers understand crime novels set in a city, and even the rest of us mystery lovers are intrigued by how characters navigate the obstacles of city life.[image error]
I recently have been on a search for readers who enjoy wilderness mysteries. Most authors, except Stephen King, John Grisham, and a few others, must work to find readers. Nearly 5,000 books are published every day on Amazon, so in this sea of books, how does a reader find authors who write the type of books he likes? How does a new author make a living at writing? It isn’t easy, and it may be impossible to succeed in today’s book marketplace unless you are lucky or connected.
Authors are dreamers by nature, though, and I believe one day, I will find my core group of wilderness mystery readers, and they will tell their friends who will tell their friends. Over the last several weeks, I have been connecting with folks on LinkedIn and telling them about my books and my newsletter, and several of my new connections have signed up for my newsletter which thrills me.
I am an introvert, so reaching out to people on LinkedIn has demanded courage. I have been exhilarated by the results, though. Frances Joyce the publisher of the e-zine This Awful-Awesome Life asked me to write an article about Kodiak and its wildlife, and I jumped at the opportunity. Then, I connected with Pamela Beason, a popular wilderness mystery writer who lives in Washington state. We hope to work together in the near future to promote our books. Pam’s mysteries featuring wildlife biologist Sam Weston are excellent. If you enjoy wilderness mysteries, you will love hers.[image error]
James Hayman is my latest interesting LinkedIn connection. He is the New York Times bestselling author of the mystery series set in Portland, Maine featuring detectives McCabe and Savage. As soon as we connected, Jim asked me if I would be interested in writing a guest blog post for him about where I live on Kodiak Island and how I use this setting for my novels. My post is now available on his site: http://jameshaymanthrillers.com/blog/. I hope to convince Jim to write a blog post for me. I recently read his novel, The Girl on the Bridge, and I highly recommend it. I plan to read the rest of the series, and if you enjoy mysteries, I’m sure you will want to read his books as well.
Do you enjoy mysteries set in the untamed wilderness where characters must navigate hostile environments, raging storms, Kodiak bears, and other wild animals? If you think you would be interested in reading an Alaska wilderness mystery, or you know someone who would be interested, sign up for my webinar (http://bit.ly/2pcCOo6), and at the end, you can download a copy of one of my novels. The only purpose of my webinar is to introduce myself to new readers. You can decide for yourself if wilderness mysteries are for you.

When Do Eaglets Leave The Nest?
[image error]
Three weeks after hatching, eagle chicks, or eaglets, molt to a thicker, darker down which remains until the first set of feathers develop. At this stage, one of the parents remains near the nest to shelter the chicks from direct sunlight, inclement weather, and anything else that can harm them.
When an eaglet first hatches, its bill and eyes are dark-colored. Over the course of three to four years, the bill lightens to a swirl of shades of brown, then to yellow-brown, and finally to bright yellow. The eyes lighten to buff yellow by one-and-one-half-years, light cream by age two-and-one-half, and pale yellow by three-and-one-half.
As the chicks develop feathers and grow, the parents spend less time at the nest and more time hunting for food. The eaglets grow very rapidly as long as the parents can provide sufficient food. If the parents are unable to find enough food, the smallest chicks might die.
At one-and-one-half to two-weeks, most young eagles weigh one to two lbs. (500 to 900 grams). Between 18 – 24 days, chicks gain four ounces (100-130 grams) per day, a faster weight gain than at any other stage of their development. Eaglets begin feeding themselves around the sixth to seventh week, and by eight weeks, they can stand and walk around the nest. At sixty days, eaglets are well-feathered and have gained 90% of their adult weight. Large nestlings consume nearly as much food as adults.
Chicks remain in the nest for ten to twelve weeks. A week or two before they fledge, they can be seen on the rim of the nest exercising their wings and holding onto the nest with their talons. They flap their wings and may even lift off the nest. A chick can fall or be blown off a nest while exercising, and if it can’t make it to another branch, it might fall to its death. Biologists estimate one in seven eaglets fledges prematurely, either falling or jumping from the nest before it can fly.
[image error]
Once their muscles and wings are strong enough, eaglets are ready to leave the nest. What prompts the chicks to fledge is a matter of speculation, but at some point, the parents cut back on the amount of food they provide their young, and they may even use food to lure the chicks away from the nest. Males fledge at an average of 78 days, and females fledge at an average of 82 days. Research in Southeast Alaska shows fledging there occurs on average in mid-August.
The first several flights of a fledgling are very clumsy, and their first few landings are usually crash landings. Juvenile birds have longer wings and tails than adults, and this makes learning to fly easier for them. As an eagle matures, its wings become shorter and narrower, and the tail gets shorter with each molt.
Immature eagles usually stay within a half-mile radius of the nest for the first six weeks after fledging, and they may even continue to receive food from their parents during this time. Eight to ten weeks after fledging, they seem to develop a stronger instinct to move further away from the nest.

When do Bald Eagles in Alaska Lay Their Eggs, and When do the Eggs Hatch?
[image error]
Bald eagles lay their eggs in mid to late May in southern areas of Alaska, although one study in Southeastern Alaska indicated that they might lay their eggs as late as early June. The female lays between one and three off-white-colored eggs in a span of one to three days. The eggs range in size from 2.76 inches by 2.09 inches (70mm by 53 mm) to 3.31 inches by 2.36 inches (84 mm by 60mm).
The eagle pair begins incubating the eggs as soon as they are laid. The male and female share the incubation duties, and each mate hunts for its own food. Studies show that for 98% of the day, either the male or female sits on the eggs. The incubating bird stands up about once per hour and may change positions. A study at several nesting sites on Admiralty Island in Southeast Alaska found eggs were incubated for 95% of the daylight hours with females sitting on the eggs 53% of the time, and males tending the eggs 42% of the time. Brooding time dropped to 79% of the day for the first 10 days after the eggs hatched and by 41 to 50 days after hatching, the brooding time decreased to only 6% of each day. Brooding time increased when it was rainy and decreased when it was sunny. The incubation period takes 34 to 36 days. Since individual eggs may be laid a few days apart, they will not all hatch at the same time.
The hatching process is slow and arduous. It takes chicks twelve to forty-eight hours to fully emerge from the egg. The chick makes the first crack in the shell with its egg tooth, a small, hard bump on the top of the bill. After resting awhile, it then chisels around the large end of the egg. It eventually pushes off the end of the egg and wriggles out of the shell. The egg tooth dries up and falls off four to six weeks after hatching.
During hatching, a chick must undergo several physiological adaptations. Before it hatches, a chick absorbs oxygen through the mat of membranes under the shell. During the hatching process, it must cut the blood supply to these membranes and trap the blood within its body. At the same time, it must also inflate its lungs and begin breathing air once it has cracked the shell. The chick must also absorb the yolk sack into its body and seal off the umbilicus.
Newborn chicks are wet, exhausted, nearly blind, and extremely needy. Since a newly-hatched chick can’t regulate its body temperature, the parents must keep it warm. The chick is covered with pale gray down. The skin and scales of the legs are bright pink, the bill is a grey-black with a white tip, and the talons are flesh-colored. After the first week, the legs begin to turn yellow.
[image error]
Eagles lay one to three eggs, but usually, only one or two chicks survive. Survivability is directly correlated to age. The first chick to hatch will be one to two days older than its siblings, so it will be larger and stronger and able to out-compete its nestlings if food is limited. If a brood has three chicks, the smallest chick usually dies within a week of hatching. Death is not normally caused by injuries from fighting with its siblings, but the chick simply starves to death because the older nestlings get all the food. The older chicks peck the young chick into submission to prevent it from eating enough to survive. By doing this, the older chicks ensure they have plenty of food.

Bald Eagle Nest Building
[image error]
Spring is a time for nest building; whether it’s a new nest made from twigs or a hollow spot in a rock needing only a fresh supply of moss for padding, birds know they must prepare their homes for the eggs and chicks that will soon follow.
Our weather is slowly warming here on Kodiak Island. Most days we creep into the forties, but then we drop back into the low thirties at night. I see a few sprouts popping through the ground, but mostly, it still looks like winter here.
Animals are the one, true indication spring is right around the corner. I hear whales exhaling in the pass near our lodge, signaling they are following the krill and small fish into the bay. In turn, the krill and fish are here to feed on the phytoplankton which blooms as the water warms. Yesterday, kittiwakes arrived in a big swarm to repopulate the rookery in front of our lodge. Puffins and arctic terns should be here soon.
The surest promise of spring, though, is the circling eagles high in the sky as they perform their mating ballet. Soon, they will begin repairing their homes as they prepare for their young to be born.
Bald eagles build the largest nest of any North American bird. The nest may be as large as 8 ft. (2.44 m) across and weigh one ton (907 kg). An eagle pair often uses and adds to the same nest every year, causing the nest to grow over time.
Bald eagles build their nests in large trees near the water. In Alaska, nests are usually found along saltwater shorelines or rivers, and in many parts of Alaska, eagles nest in old-growth timber. On Kodiak Island, eagles prefer to nest in black cottonwood trees, but in areas where black cottonwoods are not available, nests can be found on rocky cliffs or at the bases of alder trees on cliffs along the coast.
[image error]
The nest is usually built in the crotch of the last set of branches one-third to one-quarter of the way down from the top of the tree. Eagles tend to nest in trees with sparse foliage near the edge of a habitat, so they can fly to and from the nest without having to navigate through a canopy of trees.
The nests are built of sticks, and each year the eagle pair adds new branches and other vegetation to the nest to cover over food remains, feathers, and other debris left from the previous year. Branches and twigs are placed on the edge of the nest, while softer vegetation such as leaves, grass, and moss are placed in the center. An eagle pair continues to add branches, moss, and grass to the nest all summer until the chicks are nearly grown. Researchers believe the reason for this may simply be to keep the nest cleaner. Waste, rotting fish, and even the bodies of chicks that have died in the nest are not tossed out of the nest but are buried by moss, grass, and other greenery. It is important to keep the nest clean, so parasites don’t infest the chicks.
An eagle pair usually uses a nest until either the eagles die or something happens to the nest or the tree holding the nest. Mates may build two, three, or even four nests in their breeding territory, and scientists are unsure what the purpose is for these multiple nests.
The average distance between occupied nests is usually 1 to 2 miles (1.6 – 3.2 km), but nest sites are often closer to each other in areas where food is plentiful. A 2007 nesting and productivity study on the Kodiak National Wildlife Refuge identified 1141 nests with 439 (38%) of those nests active. This was down from a 55% occupancy rate found in a 2002 study. Of the 439 active nests in 2007, 208 of the nests (48%) were successful in producing young. The researchers suspected the harsh spring weather in 2006 and 2007 might have contributed to the reduction of nesting effort.
Nesting and breeding bald eagles are territorial and defend their nests from other animals, including other eagles. Adults spend much of the day perched in prominent trees near the nest, perhaps to make themselves more visible to intruders. A resident eagle will warn an approaching eagle with a loud call consisting of grunts followed by a high-pitched screech. Sometimes the resident eagle quietly escorts an intruder out of the area, but occasionally, one of the two birds will attack the other, resulting in a display known as cart-wheeling, where one eagle descends on the other eagle, and the other bird rolls onto its back while both eagles grasp talons. The two birds then tumble toward the ground, separating just before they crash.
I welcome the birds back after a long winter. They are often noisy neighbors, but their cries herald birth, life, and spring!

Kodiak Bear Management
[image error]
Wildlife management most often involves managing humans. Research allows biologists to understand the needs and habits of wildlife, and this research hopefully leads to management policies to enable human populations to better coexist with wildlife. Wildlife management is never easy, and Kodiak is no different from anywhere else. Various user groups attempt to pressure wildlife managers into making decisions to further their particular interest, and managers struggle for a balance to try to accommodate a variety of users while protecting the wildlife and the habitat.
On the Kodiak Archipelago, I am proud to say the management of bears and their habitat is not only done well, but it is done so well, it is considered one of the best models of wildlife management in the world. The Kodiak National Wildlife Refuge managers, the Alaska Department of Fish and Game, the native corporations, and the citizens of Kodiak work well together to safeguard bears and protect their habitat.
History has shown us that protecting wildlife habitat is often the most difficult aspect of wildlife management, whether there is oil to be drilled, copper to be mined, trees to be cut, or roads and houses to be built, economics often wins while wildlife loses huge chunks of critical habitat. Brown bears require large tracts of wilderness to survive, and as the human population grows, it becomes more and more difficult to protect the bears’ home from economic and residential development.
The Kodiak National Wildlife Refuge is the largest intact, pristine island ecosystem in North[image error] America. The Refuge encompasses 16 lakes, 117 salmon streams, wetlands, grasslands, shrublands, Sitka spruce forest, tundra, and alpine meadows. This habitat supports 250 species of fish, birds, and mammals, including 400 breeding pairs of bald eagles. It supports 3000 bears, and an estimated 3500 bears live on the Kodiak Archipelago.
One of the stated purposes of the Kodiak National Wildlife Refuge is to conserve fish and wildlife populations and habitats in their natural diversity, including, but not limited to, Kodiak brown bears, salmonids, sea otters, sea lions, and other marine mammals and migratory birds.
The Kodiak National Wildlife Refuge was established in 1941 in response to concerns by bear hunters for the health and survival of the Kodiak brown bear population. The original mission of the Refuge was “to protect the natural feeding and breeding range of the brown bears and other wildlife on Uganik and Kodiak Island.” Without the strong lobbying efforts of hunting groups, it is doubtful the Kodiak National Wildlife Refuge would have been formed. The sale of bear hunting licenses and bear tags on Kodiak generates over $250,000 annually, and much of this money is used for research and habitat protection.[image error]
Bear hunting on Kodiak today is very tightly regulated. Each year, 4500 people apply for the 495 available bear-hunting permits. Of these 495 hunters, approximately 175 are successful, and 75% of the bears killed are male. All hunters must check in with the Alaska Department of Fish and Game office in Kodiak before going into the field, and they must check out with Fish and Game before leaving the island. Every bear killed must be inspected by an Alaska Department of Fish and Game biologist before it can be taken off the island. Because these strict regulations have the overwhelming support of guides and residents, illegal bear hunting on Kodiak is rare.
Perhaps the most telling fact proving the Kodiak bear and its habitat are well managed is the 3500 brown bears currently living on the Kodiak Archipelago. Biologists believe this is the largest the Kodiak bear population has ever been.

Have Kodiak Bears Changed Their Feeding Behavior?
Last week, I discussed a recent scientific study chronicling Kodiak bear feeding behavior during the summers of 2014 and 2015. I pointed out that while the study fascinated me, I was less enthusiastic about the flood of inaccurate leaps in logic following the publication of the research. Please refer to last week’s post if you haven’t read it, so my post this week will make sense to you.
I invited most of the authors of the study, Kodiak National Wildlife Refuge officials (the research was in part supported by the Refuge), and other biologists and guides on the island to read my post and share their thoughts on the study. I was curious to know what others who work in the field on Kodiak thought about the flood of publicity over the past few months stating as our climate warms, Kodiak bears are changing their feeding behavior and are abstaining from salmon while they eat their fill of elderberries. While I didn’t get many replies here on my website, I did receive several e-mails, and without mentioning any names, I will share some of those with you.
[image error]I know I just said I wouldn’t mention any names, but I do want to state that Dr. Deacy, the lead researcher on the project, sent me a very nice e-mail soon after I asked him to look at my post. He was on a deadline for another project but said he would respond in more detail when he had time. He couldn’t have been nicer, and I exhaled a long, slow breath when I read his response because Dr. Deacy has been generous with his time in explaining this as well as other, recent bear research to me. I didn’t want to anger him or anyone with my critique of the study.
One of the other researchers on the study was not as thrilled with me, and he seemed to think I was personally attacking him and the other biologists. I admit I am partially to blame for his anger because I stated scientists sometimes seem as if they are in a bubble. He equated this statement with me saying scientists never come down from their Ivory Towers – a term I did not, nor would not, use. After his message, I was afraid to look at my e-mail for the next few days, but the rest of the replies I received were positive.
Biologists and guides alike felt the conclusions stated in this study opened the door to the wild, speculative media reports following it. Two people mentioned an important point. Some Kodiak bears spend most of their lives in alpine regions on the island and eat neither elderberries nor salmon. As with humans, what bears eat varies from one area to another and from one individual to the next.[image error]
I hope most people who read articles with titles like, “Kodiak bears go vegetarian,” will stop for a moment and question such a wild claim. I applaud wildlife research and think this research is necessary, not only to understand the magnificent wild animals who share this planet with us but also because this research points the way to appropriate wildlife management decisions. I don’t, however, believe research should ever be done to prove a case. The point of research should be the search for truth.
Speaking of wildlife management, next week I will write about bear management on Kodiak Island. Thank you for reading my post.

Elderberries, Salmon, or Both?
[image error]
Bears are omnivores, and on Kodiak, they eat a large buffet of food items, including elderberries and salmon, two of their favorite foods. What happens, though, if a bear has a choice between elderberries or salmon? Which will he choose, or will he choose both? More importantly, why does it matter?
I’m sure you have controversies in your neighborhood. It may be a fight over a bill to fund a new school, a fight over a tougher crime initiative, or something as simple as whether or not to put a stop sign at the end of your street. In my neighborhood here in the wilderness, the recent research I’ll discuss in this post is what we call controversy. I’ve avoided writing about this scientific article until now because I know I will irritate several people, some of them friends. I finally decided, though, I couldn’t continue to avoid voicing my opinion on something this significant. I have invited some of the biologists involved in this study, other biologists, and local guides to read my blog, and I hope they will weigh in on the issue by leaving comments. I am sorry this post is long, but I didn’t want to break it into two parts.
The study I will discuss is titled, “Phenological synchronization disrupts trophic interactions between Kodiak brown bears and salmon.” It was published in the July 18th edition of the Proceedings of the National Academy of Sciences. I think it is an excellent study, and more importantly, other biologists must think it is an excellent study. The Proceedings of the National Academy of Sciences is a prestigious scientific journal, and to be accepted by this journal, a research paper must be peer-reviewed at the highest level. I do not disagree with the methods or the results of the study. What I do have a problem with are the broad, far-reaching conclusions drawn from what is, in my opinion, a preliminary field study.
Let me do my best to explain the focus and significance of this study. A large body of research concerns what happens due to global warming when coevolved species shift out of synch with each other. For example, consider a plant that is only pollinated by one bee species, and these two species co-evolved so the plant flowers at the exact same time the bee is ready to gather its nectar and pollinate it. What happens, if the bees hatch earlier each year due to a warming environment, but the flowers bloom at the same time because their cue for blooming is based on the amount of daylight, not temperature. The two species will slowly grow out of synch with each other, and the plant species may go extinct when the bees are no longer available to spread its pollen.
In this study, though, lead researcher William Deacy and his colleagues set out to investigate the opposite situation: what happens when warming temperatures cause climate-induced synchronization? In this case, when elderberries fruit several weeks earlier than usual on Kodiak Island during the middle of the sockeye salmon run, will bears choose to eat salmon or berries?
The Karluk River on Kodiak Island, where this research was done, supports a large sockeye salmon run lasting from June to early August. On a normal year, bears on the Karluk River feast on sockeye and other salmon until late August, when they begin eating elderberries and salmonberries which are just then ripening. Once the berries are gone, bears return to the river and side streams to eat other species of salmon.
When William Deacy worked on another research project in the Karluk area in 2013, he noted typical bear behavior. Throughout July, bears ate their fill of salmon and left the scraps for birds and other animals to scavenge. In 2014, after a warm spring, elderberries ripened two weeks earlier than usual, and plants produced ripe berries longer than normal. Deacy noted that bears in late July were eating berries instead of fish. Why, he wondered, would bears opt for elderberries over sockeye salmon? The winter and spring of 2015 were also warm, and Deacy again observed bears ignoring sockeye salmon while they ate berries.
Deacy and Kodiak National Wildlife Refuge biologist Bill Leacock gathered a team of scientists from several universities and organizations, including Oregon State University, the University of Montana, Washing State University, and the National Park Service, to examine this surprising bear behavior.
From meteorological records, the biologists determined the temperature on Kodiak is slowly getting warmer, and 2014 was the warmest year on record. When the winter and the spring are relatively warm, elderberries ripen earlier than normal, and when elderberries ripen earlier, bears seem to eat berries instead of salmon. What, they wondered, will happen when temperatures continue to warm? If the berries are ripe all summer, will bears only eat berries and ignore salmon? If this happens, what will the birds and small animals eat? They depend on bears to leave them scraps of salmon on the banks of streams. Not only do animals depend on bears for leftover salmon, but salmon carcasses provide fertilization for riparian vegetation. Another point of concern is if bears only eat berries and avoid salmon, will bears get enough nutrition?
Deacy and his colleagues headed for the lab to determine if elderberries are nutritious enough to sustain bears, and why bears like berries better than salmon. Fortunately, elderberries are protein-rich compared to other berries. They don’t have as much protein as a salmon, but a bear would do fine if he ate elderberries instead of salmon. I won’t discuss the part of the study suggesting why bears prefer elderberries over salmon because I believe this conclusion is based on a very shaky assumption.
Do bears prefer elderberries over salmon, and if provided with both, would they choose the berries? I don’t know the answer to this question, and neither does William Deacy or any other biologist. As I said earlier, I think this is a well-done, interesting, thought-provoking study, but let ’s not get carried away. This is a preliminary study consisting of three years of data taken over a fairly small geographical area. It is unprofessional for any biologist to draw sweeping conclusions from a limited, preliminary study.
I would like to believe the media is responsible for jumping to wild conclusions regarding this research. I corresponded with Dr. Deacy after the research was published and asked him if he was trying to say bears are now eating berries instead of salmon. I may have misunderstood him, but I thought he said he was only suggesting what might happen as our climate warms. Then I found articles titled, “Alaskan grizzly bears choose berries over salmon—thanks to climate change,” “Kodiak bears found to switch to eating elderberries instead of salmon,” “Grizzly bears go vegetarian due to climate change, “Climate change is luring Kodiak bears away from their iconic salmon streams,” and “As a warming climate changes Kodiak bears’ diets, impacts could ripple through ecosystems.” Deacy, himself, wrote this last article. In it, he claims, “climate change dramatically altered bear behavior.”
The researchers state the ecosystem on Kodiak Island has been disrupted. I have lived in the Kodiak wilderness and have helped my husband guide bear viewers for 35 years. My husband has lived in the Kodiak wilderness all his life. Warm springs and big berry crops are not unusual, and when the berries, especially salmon berries and elderberries, ripen, we know we will see fewer bears on the rivers feeding on salmon where we can show them to our eager bear viewers. The bears will instead be in the bushes eating berries. I seriously doubt bears prefer berries to salmon, though! Berries are an easier food source than salmon because all the bear has to do is sit on his rear end and eat them. He is required to expend energy to chase down a salmon.
I believe either from instinct or learned behavior, bears know that when berries ripen, they are usually only available for a short period. Salmon, though, can be eaten from June into November. One fact I feel these researchers did not stress enough is that five species of Pacific salmon return to spawn each year in the streams and rivers on Kodiak Island. Pink salmon, not sockeye salmon, are by far the most prevalent of these species, and I have thousands of photos to prove how much bears love to eat pink salmon. Pinks are in the rivers until late September, and Coho salmon remain in the rivers until November.
Yes, the spring and summer of both 2014 and 2015 were warmer than usual, and the berries were plentiful. Once the berries began to decline, though, bears were back on the rivers eating their fill of salmon and leaving scraps for the birds and other animals. I suspect when these warm springs and summers become the norm, bears will learn they have a longer period to eat berries and will split their time between berries and salmon. I may be wrong, and bears may choose berries, but I know it should take more than a two-year study before biologists begin telling reporters that Kodiak bears have abandoned salmon for berries.
The spring and summer of 2017 were cool. The berry crop was poor, and the salmon run on Kodiak was better than it has been in several years. Bears packed the salmon streams, and we wondered whether they would eat enough berries to gain the necessary calories they need to carry them through hibernation. A biologist arriving at Karluk Lake last summer observing abundant salmon and few berries might have designed a very different research study from the one I’ve been discussing in this post.
What worries me, is that as the planet warms, salmon populations will drastically decline because salmon are sensitive to even a small increase in water temperature. As this research suggests, though, when salmon are no longer available, perhaps bears will maintain a healthy diet by eating berries.
I would like to make one more comment before I get off my soapbox. Why must biologists live in a bubble? Why didn’t the researchers in this project talk to guides who have been watching bears for decades? I realize they can’t use anecdotal evidence in their study, but perhaps we could have offered possibilities in addition to the conclusions Dr. Deacy made.

Genetic Studies and More Kodiak Bear Research
Last week, I discussed early studies on Kodiak bears, and this week I want to continue by talking about more recent research, including some troubling genetic studies.
A 1996 genetic study questioned whether Kodiak bears should be considered a separate subspecies from other Alaskan brown bears. A 1998 study on the genetic diversity of North American brown bears indicated genetic diversity among Kodiak bears is much less than it is for other populations of North American brown bears. Several of the bears sampled on Kodiak had identical genotypes. A study by Paetkau and colleagues further explored the genetic isolation of Kodiak bears from other Alaskan brown bear populations.
A 2006 report for the Kodiak National Wildlife Refuge illustrates that Kodiak bears have extremely low levels of genetic variation at neutral nuclear microsatellite markers. The level of genetic variation in Kodiak bears is much lower than the variation found in any other brown bear population. Furthermore, this low level of variation is not only found at neutral markers but also in nuclear-functional genes. While the Kodiak bear population is presently healthy, this low genetic variability makes this population susceptible to novel parasites and pathogens that may somehow reach Kodiak and infect bears.
Bear research is ongoing on the Kodiak National Wildlife Refuge. Yearly intensive aerial surveys yield population counts, and aerial stream surveys determine the number of bears on certain streams and study the population profiles of the bears on each stream (the percentage of single bears, sows with newborn cubs, sows with one-year-old cubs, etc.).
The Alaska Department of Fish and Game is studying the population characteristics and habitat use of brown bears on Afognak Island since the movements and ecology of Afognak bears are not well-understood.
In 2010, William Leacock headed a two-year project near Karluk Lake on the Kodiak National Wildlife Refuge to collar and track several Kodiak bears. Each bear in the study was fitted with a GPS collar to broadcast the bear’s location at hourly intervals. A Refuge pilot with an antenna attached to the wings of his plane flew over the bears and picked up the GPS signal from the radio collars of each bear being tracked. A crew member then downloaded these GPS points onto a laptop. From this information, the researchers were able to study the detailed movements of each bear and record the preferred habitat, food preferences, and bedding choices of each animal. Once the GPS data were collected in the field, volunteers hiked to the exact locations where each bear had been and recorded the types of food plants available in the area as well as other pertinent information. The goal of this study was to quantify behavioral responses of Kodiak bears to resources that vary in time and space (such as salmon runs and berry production). Dr. Leacock and his associates also studied how fluctuations in abundance of salmon at various streams near Karluk Lake influenced bear movements and exploitation of those streams.
Next week, I’ll discuss a new study that is both fascinating and controversial. I hope to invite the researchers on the study as well as guides who have been watching bears and their behavior for years to read my post and comment on it. Maybe I can get a lively discussion started! Be sure to check back often.

Kodiak Bear Research
Biologists with the Alaska Department of Fish and Game and the Kodiak National Wildlife Refuge are responsible for most of the research on Kodiak bears, and much of this research has concentrated on denning behaviors and home ranges of Kodiak bears, with an emphasis on management applications. Today, the Kodiak Brown Bear Trust funds a portion of bear research. The trust was established in 1981 to compensate for potential impacts on Kodiak bears by the construction and operation of the Terror Lake Hydroelectric Project. The trust funds bear research, management, habitat protection, and educational outreach projects. The Kodiak Brown Bear Trust relies on tax-deductible contributions to carry out its mission. If you would like to support Kodiak bear research and habitat protection, please visit www.kodiakbrownbeartrust.org to learn more about the trust and how you can donate.
In 1896, C.H. Merriam visited Kodiak and confirmed reports that Kodiak bears were the largest bears in the world. He named the species in honor of Russian naturalist Dr. A. Th. Von Middendorff. Merriam divided the North American brown and grizzly bears into eighty-six forms based on slight variations in size, fur color, and skull shape. Scientists now know physical differences in these categories can occur within populations and even within family groups. Today, all North American brown bears, grizzlies, and Eurasian brown bears are grouped into the single species Ursus arctos. Kodiak bears are classified Ursus arctos middendorfi, and all other brown and grizzly bears are listed as Ursus arctos horribilis.
[image error]The first scientific studies of Kodiak bears were simple hunting and collecting trips to document their size. In the early 1900’s, research was concerned with determining how many cattle and salmon bears were killing and eating. A study by W.K. Clark in 1955 showed although bears are very effective at catching salmon in a stream, they catch few unspawned salmon, making their impact on the salmon run much less than originally believed.
As the Kodiak bear became a valued trophy for big game hunters, the focus of the research shifted to learning more about the physiology and behavior patterns of bears. Biologists refined techniques for capturing and marking bears and began to use radio telemetry to track the movements of specific bears. This jump in technology provided biologists with information on home ranges, densities, gender and age ratios, and litter sizes.
Most of the early research on Kodiak bears was conducted on the south end of Kodiak Island, but in 1982, construction began on the Terror Lake Hydroelectric Project on the north end of the island, and funds were made available to study if this project would affect bears in the vicinity of the proposed dam. Biologists were surprised when studies on the bears near Terror Lake showed bears in this area had different denning behaviors and preferences than did bears on the south end of the island, indicating that Kodiak bears have adapted well to the slightly different habitats on opposite ends of the island.[image error]
In the 1970’s, a study investigated Kodiak brown bear use of alpine habitat during the summer months and preferred plant foods of bears, while a study published by Victor Barnes in 1990 examined the influence of salmon availability on the movements of brown bears. A 1994 study by Barnes investigated the impact deer hunters have on Kodiak bears, and a 2006 paper by Barnes discussed his study on the impact of bear viewers and photographers at O’Malley River on Kodiak Island. This study showed that while a regimented bear-viewing program impacted bears less than a non-regimented program, bears were still affected much more by a regimented bear-viewing program than they were when the area was closed to public use. I think the important lesson to learn from this study is that any time you step into the bears’ habitat, you are impacting them to some degree.
Next week, I will tell you about recent research on Kodiak bears. As always, thank you for visiting my blog.
