Parasite Treatment in Buffalo Could Help Spread of TB

Buffalo

A helicopter flew close to the ground in Krueger National Park, South Africa, executing a series of aerial acrobatics in order to steer the herd of African buffalo (Syncerus caffer) towards a good area for a park veterinarian to start shooting tranquilizer rounds.

Meanwhile, Vanessa Ezenwa, associate professor of ecology and infectious diseases at the University of Georgia, and a group of other researchers waited in a 4X4 on the ground nearby for the right moment to go in and tag the buffalo with satellite tracking devices.

“It can be highly dramatic,” Ezenwa said. But tranquilization was a relative term as it applied to the buffalo, and park technicians had to go in first, grab the animals by their thrashing horns, and hold them relatively steady while the researchers did their work.

“They’re still quite aggressive by nature. They’re feisty even though they’re darted,” she said.

Ezenwa was working on a project to test the relations between parasitic worm treatments and tuberculosis — a study that had wide-ranging implications for managing interactions between cattle and wildlife and potentially even human health and treatment strategies. The study, published today in the journal Science, found that treating the buffalo for worms could actually cause larger populations of buffalo to become infected by tuberculosis.

The line of thinking goes like this: If you treat an individual buffalo that also has tuberculosis for parasitic worms, the animal’s immune system will be stronger and allow it to survive longer with the lung disease.

While this may be good for the infected individual, Ezenwa said that it could be bad for larger populations of buffalo. “The negative side effect is that the individual who lives longer is able to spread the infection for a longer period of time.”

After initial tagging and testing operations, technicians working with her team had to go back in 4X4s with tranquilizer guns twice a year to re-catch the animals and test them for disease — a comparatively smaller operation than the initial tagging.

Her research also showed that treating uninfected buffalo for parasitic worms doesn’t make them more resistant to tuberculosis. “De-worming has no effect on an individual’s chance of getting infected.”

Bovine tuberculosis was introduced to African buffalo via cattle populations and while the buffalo aren’t endangered, Ezenwa said sustaining populations of the species is important because they contribute to the local economy through hunting and ecotourism.

Ezenwa also said that the study could have larger implications for understanding diseases in wildlife and disease-control strategy. She said that American bison also have common parasitic worm infections that could interact in some way with brucellosis — a disease that is currently creating hurdles for the animals’ recovery in western provinces as bison can transmit the disease to cattle.

“These worms potentially affect other things,” she said. “We have a lot of diseases that are shifting their geological regions.”

In order to look more closely at potential interactions, Ezenwa said her next study will likely look at the interactions between parasites and brucellosis among the African buffalo, which also carry the disease.

“You can translate that story to issues in the U.S.,” she said in reference to the fact that these future studies could be useful when looking at management strategies for American bison and brucellosis.

Finally, Ezenwa said the information could have an impact on the way we plan disease treatment for human populations. She said that some people have considered using parasite treatments in poorer areas where the problems are endemic as ways to reduce the overall number of people who contract HIV or tuberculosis.

“Worm drugs are relatively cheap and effective” in comparison to treating these more serious diseases, she said. But the results of her study show that using anti-parasitic treatments as a way to indirectly reduce the spread of HIV or tuberculosis may not work, and that the interaction between parasites and diseases “is more complicated than we previously thought.”

The Impacts of Energy Development on Wildlife

Pinedale Anticline

TWS members can now access the most current science and management strategies regarding energy development through three new fact sheets. The Arctic National Wildlife Refuge, Impacts of Wind Energy Development on Wildlife, and Oil and Gas Development in the Rocky Mountain Region fact sheets were developed and released by the Society to inform wildlife professionals, decision-makers, and the general public on the potential impacts of energy development on wildlife resources.

The Arctic National Wildlife Refuge fact sheet details potential impacts of oil and gas development in the Alaska-based refuge. The 1002 Area of the refuge may contain substantial amounts of oil and gas, but is also of vital importance to many wildlife species.

The Oil and Gas Development in the Rocky Mountain Region fact sheet also provides information on oil and gas development, but in a different area of the U.S. Unlike in the Arctic National Wildlife Refuge, oil and gas development has boomed in the Rocky Mountain region since the 1970s. This development has impacted wildlife through displacement, reduced recruitment, and mortality.

The Impacts of Wind Energy Development on Wildlife informs members on one of the new renewable energy options available to replace traditional oil and gas energy sources. Wind energy, although renewable, can impact wildlife, through collisions and habitat degradation.

These energy development fact sheets, along with other policy resources, can be accessed at wildlife.org/policy.

Fleeing Birds Sense Distant Tornadoes

Golden-winged warblers

Hold on to your ruby red slippers, Dorothy. Mother Nature may have her own tornado-warning system. Just days before a series of tornadoes hit the Central and Southern United States this past April, five small, neotropical birds showed some strange behavior. Golden-winged warblers (Verminvora chrysoptera), from a population that winters in Eastern Colombia, South America, and summers in the Cumberland Mountains of Eastern Tennessee, vacated their summer breeding territories in what researchers believe may have been anticipation of a major storm brewing hundreds of miles away and moving in their direction, according to a study published online in Current Biology.

“At the same time that meteorologists on the Weather Channel were telling us this storm was headed in our direction, the birds were apparently already packing their bags and evacuating the area,” said Henry Streby of the University of California, Berkley in a statement. In May, 2013, Streby and a team of researchers tagged 20 male golden-winged warblers with light-level geolocators—an electronic, tracking device that measures changes in light levels as a terrestrial animal migrates north or south or marine animals dive between shallow and deep waters. The researchers wanted to see if the small bird could carry the device for a year. Gold-winged warblers weigh about a third of an ounce, the heft of approximately four dimes, and the trackers weigh about five percent of their body weight.

Earlier this year, the team returned to recover the geolocators. On April 28, 2014, about a week after thier arrival in Tennessee, a sever thunderstorm system, called a supercell, swept through the survey area around 11 pm. Supercells sometimes give rise to tornadoes, and this particular storm system generated 84 confirmed tornadoes and caused at least 35 human fatalities. Afterward, the team recovered five warblers with geolocators.

The data showed that these warblers had evacuated their breeding grounds a day or two before the supercell hit, when the storm was 250-550 miles away. Additionally, the warblers appeared to fly around the supercell, taking different routes from one another. Three of the birds travelled more than 900 miles round-trip. “It is the first time we’ve documented this type of storm-avoidance behavior in birds during breeding season,” Streby said, though what exactly cued the birds to leave remains a mystery. When the birds left, local weather conditions were normal.

The researchers believe the birds could hear rumblings of the storm before it arrived. Tornadoes produce strong low-frequency sounds, called infrasounds, occurring at frequencies below the normal range of human hearing. According to the National Institutes of Health, humans can normally hear sounds from 20-20,000 hertz. Because lower frequencies travel farther, the infrasonic sound resonating from the supercell storm system could have gone hundreds to thousands of miles before petering out. This means it is possible that the warblers could hear the storm coming from only a couple of hundred miles away days before it passed through their breeding grounds.

“Biologists had not been looking at the use of infrasound in this way, but it certainly makes sense to me,” said Streby. “We may find that acoustics are a pretty significant way that birds in general view their environment, much like dogs use olfaction and humans use sight.”

White-Nose Syndrome Better Explained

Researchers have confirmed the way a lethal fungal disease has laid waste to huge populations of North American bats.

“This model is exciting for us, because we now have a framework for understanding how the disease functions within a bat,” said Michelle Verant, a scientist with the University of Wisconsin and the U.S. Geological Survey’s (USGS) National Wildlife Health Center and the lead author of a study released in BMC Physiology. “The mechanisms detailed in this model will be critical for properly timed and effective disease mitigation strategies.”

The new study proves the previous hypothesis that white-nose syndrome — a disease caused by the fungus Pseudogymnoascus destructans (formerly Geomyces destructans) — killed bats by attacking their immune systems during hibernation when they are weakest. By comparing healthy and infected bat populations during hibernation, USGS researchers discovered that bats with the fungus used twice the energy as uninfected bats. The energy depleted in the infected bats was so great that it stops the bats from performing basic body functions during hibernations, causing bats to die from suffocation or other causes.

But the researchers also discovered that contrary to previous findings, the fungus began to cause the hibernating bats to move around more and waste energy much earlier than more serious symptoms of WNS such as wing damage became evident.

“Clinical signs are not the start of the disease — they likely reflect more advanced disease stages,” Verant said. “This finding is important because much of our attention previously was directed toward what we now know to be bats in later stages of the disease, when we observe visible fungal infections and behavioral changes.”

The researchers measured energy depletion in bats by tracking the ratio of lean tissue to fat mass. Infected bats had much less fat.

The study also found that mild wing damage in bats had more acidic blood due to increased carbon dioxide levels as well as potassium levels high enough to inhibit normal heart function.

Fall Festival Highlights Busy Semester for Central Missouri

Whitetailed Deer

The fall 2014 semester was very busy for The Wildlife Society Student Chapter at the University of Central Missouri. Student members have been very involved this semester; from aging deer for the Missouri Department of Conservation to attending various conferences, members have accomplished a great amount.

Several members attended the Central Plains Society of Mammalogists in October, where students learned about research being conducted in the Central Plains and by Central Plains’ researchers, including information about black bears and bats. Soon after that another large group attended the Kansas Herpetological Society Conference. At KHS there were many speakers that discussed research being done throughout the state of Kansas and there were a lot of live animals present for attendees to observe and learn about. All members in attendance reported having a great experience at these conferences and brought back lots of new information.

In November the Chapter had a record number of members sign up and participate in the annual deer aging event with the Missouri Department of Conservation. The days were long and cold but very educational. It was interesting to talk to different hunters and to learn more about how Missouri Department of Conservation monitors deer populations, particularly for members who had never been hunting.

The student chapter’s biggest accomplishment this semester was a new event, the Fall Festival, which was held during the first weekend in November and was a huge success. This outreach event had many volunteers teaching adults and children about all kinds of wildlife. There were discussions about herpetology, mammalogy, and ornithology, as well as face paintings, a petting zoo, hayrides and lots of soup and chili. It was a great success and all the proceeds will go towards the chapter’s trip to a White Tailed Deer Ranch located in Texas in January. The student chapter will be doing a prescribed burn and learning other management practices.

Overall The Wildlife Society Student Chapter at the University of Central Missouri had a successful and fun semester and members look forward to what the spring semester will bring. For more information on the student chapter visit their website and Facebook page.

Make Your Plans Today For the Vth IWMC

IWMC 2015

This is the first time that the International Wildlife Management Congress (IWMC) comes to Asia. The Mammal Society of Japan (MSJ) in partnership with the Wildlife Society (TWS) will host this exciting congress at the Sapporo Convention Center, Hokkaido, Japan from July 26 to 30, 2015. The previous four IWMCs were held in Hungary, Costa Rica, New Zealand, and South Africa. The Vth IWMC is therefore the first at which “wildlifers” from the entire world will meet together in East Asia, and the MSJ and TWS are extremely pleased to host the IWMC 2015.

Learn more about the Vth IWMC and start making your plans to attend!

Wildlife research in Japan is today one of the greatest social interests and one of the most dynamic fields in ecological science. The islands of Japan stretch a long distance from north to south and contain a diversity of wildlife. Our natural environment provides a rich habitat for many species of mammals, birds, reptiles, and amphibians. The hosting city Sapporo, the capital of Hokkaido, is an excellent location to practice the main theme of this congress, “International Models of Wildlife Biology and Management: Beyond Cultural Differences.” Hokkaido has introduced many exemplary practices in wildlife management and human dimension studies.

However, as with many other countries and regions, Japan faces many ecological, social, and structural problems with regard to its wildlife. These call for far-reaching reforms under the leadership of the scientific community. The hyper-abundant population of sika deer is one serious social assignment. The Sapporo metropolitan area is struggling with the looming population growth of urban deer and bears. Our hunting population is rapidly declining. Our island ecosystem is prone to invasion by alien species.

The Vth IWMC hopes to attract more than 1,000 delegates from around the globe. It is an amazing opportunity for all wildlifers to share our knowledge and experiences of wildlife sciences.

Come join us in exciting discussions on all aspects of wildlife, ecology, biology, not to mention people, and in enjoying the agreeable atmosphere of the northern island of Japan, Hokkaido.

Asian Fanged Frog Gives Birth to Tadpoles

Fanged Frog

On Sulawesi, an island in central Indonesia, Jim McGuire searched for Limnonectes larvaepartus, a small species of fanged frog with a unique strategy for reproduction. McGuire, a herpetologist with the Museum of Vertebrate Zoology and the University of California, Berkley, had returned with his research team to a spot where he knew the frogs would likely be. When he found a frog sitting in a puddle, he was worried the activity around him would cause the frog to hop away, so McGuire reached down to pick it up, and “out came tadpoles into my hands,” he said. McGuire experienced first hand the pregnant fanged frog giving birth to tadpoles instead of laying eggs — the only frog known to do so, according to a new online study published in Plos One.

That the female L. larvaepartus gave birth to tadpoles that day wasn’t a surprise for McGuire. In fact, he was looking for it. His colleague and lead author of the study, Djoko Iskandar, first suspected these frogs gave birth to tadpoles in the late 1980s. More than a decade later in 2001, McGuire and his team would see for the first time tadpoles inside a female’s abdominal cavity as they opened a specimen up to take a tissue sample for genetic work.

One of McGuire’s research goals is to understand how animals on Sulawesi became different species. The island itself used to be multiple islands that merged eight to ten million years ago, and McGuire thinks this has had an important impact on how species have diversified there. Fanged frogs are a slice of that work. As many as 25 different fanged frog species may live on the island, according to McGuire, though only four have been formally described by scientists. Genetic analysis will, among other things, help the researchers distinguish between different species.

“We make a little assembly line when we are preparing specimens, so one of my grad students was actually gearing the tissuing of the frogs,” said McGuire. “He made the incision on the side of the frog and out came the tadpoles.” Since then, the researchers have observed 19 examples of L. larvaepartus females pregnant with tadpoles.

“One of the really cool things about frog evolution more generally is that there have been many, many tweaks in reproductive modes.” From guarding eggs on land to carrying tadpoles in vocal sacs, there are about 40 different reproductive modes for frogs. However, of the 6,455 species only about a dozen reproduce using internal fertilization, where the male fertilizes eggs that are inside the female. Most of those species give birth to froglets. Only L. larvaepartus uses internal fertilization and gives birth to tadpoles.

Future research may take a closer look at this species, but scientists are also interested in looking at the reproductive methods of other fanged frog species on the island. “We don’t even know what the reproductive modes are for most of these 25 or so species,” said McGuire. “One of the things we need to do is get in the field and actually observe reproduction in more of these frog species so we have a better handle of what’s happened in an evolutionary sense.”

Paths to Becoming a Wildlifer

MAKING YOURSELF MARKETABLE FOR THE WILDLIFE PROFESSION

As professors in university wildlife departments, we often receive phone calls from prospective employers — state and federal wildlife agencies, natural-resource NGOs, or private landowners — seeking students as paid or volunteer interns to help with research or management on ranches, forests, wetlands, or other habitat types. For each inquiry we ask what qualifications the employer desires, such as an undergraduate or graduate degree, specific work experience, or personal character attributes. We then attempt to match the best qualified student with the employer.

With more than 70 years of combined experience as wildlife professionals and instructors, we’ve gained many insights into what employers want, and helped hundreds of students obtain employment in the wildlife profession. In fact, we view this duty as part of our job, which is to educate future generations of wildlife biologists and prepare students to be marketable for employment. But what makes them marketable?

We feel that this question is so important that we’re co-authoring a book on the subject, scheduled for joint publication by Johns Hopkins University Press and The Wildlife Society (TWS) in 2016. What follows is a preview of what we’ve learned over the years about the qualities employers look for in potential employees, and what students can do to meet those needs.

New Skills, Old Values

You’ve heard the expression, “The more things change, the more they stay the same.” To some extent this applies to professional wildlife management and conservation, where there’s no substitute for fundamentals. It’s true that as technology improves, more employers require expertise in data processing, GIS and GPS systems, aerial or remote imaging, and social networking skills. However, most employers of all types continue to ask for the same traits in employees that have been valued for decades.

Topping their list of essentials is a solid education in wildlife. Though many part-time and seasonal technician and ranch-hand jobs may not require a college degree, full-time employment as a biologist or manager generally does require at least a Bachelor of Science, and often there’s a preference for a graduate-level degree. Students who want to obtain a thorough education in wildlife will find excellent guidance in the curriculum required for certification by TWS. This includes:

  • General courses in wildlife management, zoology, ecology, and physical science
  • Wildlife biology courses including either mammalogy, ornithology, or herpetology
  • Botany courses including plant taxonomy
  • Wildlife policy, administration, or law enforcement
  • Quantitative sciences such as statistics, modeling, sampling methods, or advanced math (calculus, biometrics, regression analysis)
  • Communications (composition, public speaking).

In addition to the basics, employers expect students to be well-versed in ecological theory and wildlife species management, with a strong understanding of human dimensions and well-developed written and oral communication skills. They also expect new graduates to understand the National Environmental Policy Act, policy development, and the North American Model of Wildlife Conservation. Beyond these book smarts, employers want new hires to be competent in the field, with experience performing a variety of techniques with the major species of their concern. Finally, employers want employees who are connected to others in the profession, which can often be achieved by attending student and professional meetings of TWS and other wildlife organizations.

We have found that new graduates often believe that if they possess the majority of these attributes, then they are highly marketable within the wildlife profession. That’s largely true, but it’s worth digging deeper to explore what really gives potential hires an edge.

Making the Grade

We have an on-going debate with our students about the importance of grade point average (GPA) in gaining employment. In our experience, a GPA of 3.0 or better is needed to secure a permanent position in the wildlife profession because it demonstrates professional competency to employers. Consider this: would you have confidence in a medical doctor who graduated at the bottom of his class, or would you prefer a doctor who earned high marks in school? If you answered the latter, then why should the wildlife profession expect any less?

A high GPA also demonstrates your dedication to the profession and shows that you set a high standard for yourself — traits that future employers assume will continue in the workplace. And students who plan to continue with higher education should consider that most graduate-level wildlife programs in the United States have a minimum GPA requirement of 3.0 for admission. Professors assume that students who maintained a 3.0 or higher GPA as undergraduates will likely continue to perform at the same level as graduate students, while students with lower GPAs may be seen as not likely to be successful in graduate school.

Some of you may feel you’re not interested in attending graduate school. But before you make such a decision, consider the experience of Josh (his real name and a true story, though Josh and most other individuals named in this article prefer to remain anonymous). Josh was an average student who graduated in the 1990s and was hired by a state wildlife agency. After 10 years of service, he noticed that several interns he trained eventually became his boss. The difference was that the interns had obtained graduate degrees. Josh decided he wanted to do the same so he could advance into higher positions within the agency. Unfortunately, Josh discovered that his 2.4 GPA as an undergraduate prevented him from admission into a graduate program, so he was destined to remain in his same job for the remainder of his wildlife career. Though he hadn’t realized it when he was an undergrad, his low grades were going to affect the rest of his life.

So our advice to students is to hit the books and keep your mind open to the possibility, one day, of attending graduate school. Employers do consider grades, and GPA matters.

No Substitute for Experience

Another attribute important to employers is hands-on experience. Employers expect new hires to have field experience with a variety of techniques and species, so it’s wise to acquire as much experience as possible while you’re an undergraduate. Attend all potential field trips offered in your classes. Go to workshops and conferences when possible. Volunteer your time to assist professors and graduate students with their research. By doing so you are investing in yourself and your future — and there may be money in the system to help you along the way.

University research grants often include money to pay for technician assistance. As professors, we typically get this assistance by hiring undergraduates within our wildlife programs. It’s also common practice to hire students who have volunteered their time in the past because we know the quality of their work, their dependability, and their personality. If all of these attributes are positive, we prefer to hire these known quantities rather than a person of unknown abilities.

Beyond volunteering, it’s smart to acquire as wide a variety of experiences as possible because you never know how or where such skills may prove useful. For example, during an interview with the U.S. Fish and Wildlife Service, one of our students was asked if he had any wood-working experience. Though he didn’t feel qualified to say “yes,” the student then remembered that once, as a member of his university’s student chapter of TWS, he had helped make duck nest boxes. As it turned out, that was exactly what the employer wanted the student to do, and the student got the job. Never think an experience is unimportant, and obtain all types of experience, including animal and plant work, habitat manipulation, policy development, and public interactions. You never know when an experience may be the key to a job.

This holds true even for work in which you have little interest. For example, when Justin was an undergraduate, he wanted to work solely with white-tailed deer: if it didn’t have antlers, he wasn’t interested. However, Justin did well in his ornithology class and became well-versed in the birds of southern Texas. This skill served him well when he landed an internship on a ranch where he led wildlife tours that included spotting birds. He did such a good job that Justin was hired as a permanent employee on the ranch, where he was able to demonstrate his knowledge and desire to work with deer. Today, Justin is the head biologist of a 300,000-plus-acre wildlife enterprise where he works with white-tailed deer daily.

Character Matters

While obtaining experience as an undergraduate, you also will be demonstrating critical character attributes such as responsibility and dependability, punctuality, time management, and good judgment. Such qualities aren’t optional; employers demand them. They need people they can count on, and people who can get the job done well and on time. Such a work ethic will be noticed by professors and employers, and will result in excellent reference letters when it’s time to move up in your career.

Case in point: Lance was an undergraduate research assistant who helped on numerous graduate-student projects. He did high-quality work and was extremely honest, always admitting if he made an error and ready to rectify the problem. He showed up to work on time, or called if he was running even a few minutes late. After a while, supervisors knew they could depend on Lance and his quality of work. This is the type of employee that everyone should strive to become — one who is competent, dependable, and completely trustworthy. Needless to say, when Lance graduated he received an excellent reference letter praising his integrity.

Keep it Positive

A positive attitude is another intangible quality often sought by employers. We have both conducted considerable research in harsh desert environments of the U.S. Southwest, where summer heat can often exceed 110 degrees Fahrenheit and humidity can top 90 percent. Beyond such physical trials, field biologists in that region also may have to contend with threats involving illegal immigration and drug runners. A person who can keep a positive attitude and sense of humor under such stressful conditions is a welcome member of any team.

Projecting a positive image also is important because wildlife professionals are often in the public eye, so the image you project may reflect on both you and your organization. This extends to your online image in this age of Facebook, a platform that has probably damaged young biologists’ careers more than it has helped their social lives.

We know of one young woman, for example, who was completing her final semester as an undergraduate wildlife major with a 3.6 GPA, a variety of animal and habitat-manipulation experiences, and solid references — all strong qualifications for a job. A state wildlife agency was considering hiring her as a biologist. As part of their background check, the agency pulled up her Facebook page and saw she had posted numerous photographs of herself drinking alcohol with friends. Because the position required the use of the agency’s trucks and boats, she was perceived as a liability threat and passed by for the job. When she learned she lost the job due to her Facebook page, she removed the photographs, but the damage had been done. Like it or not, public forums like Facebook are fair game for employers, so be sure to project a professional image if you want to be taken seriously.

Leave Your Comfort Zone

In a competitive job market like ours, you may need to venture far beyond familiar turf to launch your career. That was certainly true for Veronica, who was born and raised in southern Texas and had no desire to leave it, let alone enter Yankee territory (anything north of the Texas border). Like many new professionals, Veronica wanted to work close to home, and she hoped for a job as a biologist with the Natural Resources Conservation Service (NRCS) upon graduation. Half her wish came true when NRCS offered her a job, but it was in South Dakota, about 1,000 miles to the north. Veronica was reluctant, but decided to give it a try. Today, 10 years later, she has not only survived crossing the Texas border (and survived ten South Dakota winters), but she has built a successful career as a range specialist. The message here is: keep your mind — and your options — open.

Dream Big

Sometimes students take circuitous paths toward wildlife careers, with detours that lead to unexpected rewards. We know of one student, Andrea Heydlauff, who, after earning an undergraduate degree in English literature, wanted to work with wildlife abroad. She was so impressive and dedicated in her drive that she completed most of the additional classes needed for certification by TWS and was accepted as a master’s student at the University of Arizona, where she began working with ranchers on elk and livestock issues. Excelling in both her work and her studies, she earned her M.S. in wildlife science and soon landed a Conservation Education Fellowship at the Wildlife Conservation Society (WCS), where she taught kids at the Bronx Zoo.

At first she felt out of place as one of the only Fellows without biological training, but she stuck with it. She was hired full-time by WCS’s International Division and eventually became colleagues with such notable biologists as George Schaller and Alan Rabinowitz. Andrea worked on the Great Cats Program and the Tiger Program for WCS, and now serves as the Vice President for Panthera, a global organization dedicated to conserving the 38 species of wild cats. To top it off, Andrea recently won awards for best children’s wildlife film from both the Montana International Film Fest and Wildlife Roscars in South Africa for “My Pantanal,” her film about people living with jaguars in Brazil.

Andrea’s story emphasizes two important points. First, some “non-traditional” students such as English literature majors are worth taking a chance on if they have the drive, determination, and dedication to obtain the classes and experiences needed for a successful career in wildlife. The second related point is that if you want to obtain a career in wildlife and do not have the credentials — get to work. You can do it!

All this brings us back to basics: hard work, integrity, openness to new experiences, and determination can pave a path to success in the wildlife field, and in life.

Snowy Owls Returning, Research Continues

During the winter of 2013-14, scientists and the public throughout the eastern states were amazed – and often delighted – by an almost unprecedented influx of snowy owls. Snowy owls were reported west to Kansas and North Dakota and as far south as Florida. Rumors suggested one owl may have made it to Bermuda.

The typical migration of snowy owls reaches the southern border of Canada with northern states, such as Minnesota to Massachusetts, seeing wintering owls every year. Irruption years are characterized by many more owls and a much wider distribution. After last year’s significant event and a slightly less-impressive one in 2011, biologists have been waiting to see what this winter of 2014-15 will bring.

Last winter’s irruption also saw the creation of Project SNOWstorm, a research program to develop information about these raptors using banding, telemetry and other techniques. A total of 22 snowy owls were outfitted with GPS-GSM transmitters in the program initiated by David F. Brinker, Maryland Department of Natural Resources; Scott Weidensaul, the Ned Smith Center for Nature and Art; and Norman Smith, Massachusetts Audubon. As a part of Project SNOWstorm, Wildlife Services (WS) and those researchers trapped and outfitted two birds at the airport in Philadelphia and three in Boston.

WS biologists and specialists interact with snowy owls, primarily at airports where their size and flying habits make them hazardous to aviation. Last year’s influx prompted the Federal Aviation Administration to issue a safety reminder to the Nation’s airports.

By mid-November 2014, snowy owls were frequenting New England airports and being seen in southern Maryland. By December, Maine airports had reported three snowy owls strikes, all fatal for the birds. WS airport staff trapped owls, taught trapping skills to airport personnel, and built traps for airport use. By Dec. 19, a dozen snowy owls had been banded and relocated away from Maine airports. In Michigan, WS had relocated seven snowy owls. In one week, Michigan birding groups raised funds for three transmitters, to be outfitted on birds by WS, in cooperation with Project SNOWstorm, a primarily privately funded program.

Although snowy owls are reportedly resistant to dispersal techniques, from FY 06-13 WS staff chased about 300 away from locations were they posed a conflict and another 100 were trapped and relocated, more than half from Logan airport. Nonlethal methods accounted for 97 percent of all interactions.
