Thar She Soars!

By Zoey Greenberg, Science Outreach Leadership Trainee

Many people associate the term “birder,” with images of a khaki-clad, hat-wearing, field-guide holding, binocular-wielding, mud-splattered nature enthusiast carrying a massive camera and an intense look on their face that says “SHHH…did you hear that?” Of course, there are many types of birders (I myself bird, and wear exactly one of these items), but to those unfamiliar with the lifestyle, a birder should be dawning the appropriate materials to claim the term. Imagine then, trying to explain to a police officer that the reason you are pulled over in someone’s lawn staring at their house with binoculars is because you are, in fact, birding. You are not wearing khaki, there is no mud on your pants, but you do have a camera. He does not believe you. The camera does not help your case. This is what we call a predicament.

Such a circumstance is one of the amusing side effects of conducting road surveys to monitor vulture populations. Hawk Mountain has been doing this over the last 12 years, gradually collecting baseline data on both turkey and black vulture populations throughout the Western Hemisphere. Our protocol involves following roads that are least likely to induce rage from other drivers (we drive 40 miles per hour, and frequently swerve to hop out and count birds on cell towers, sometimes climbing the car for optimal vantage points). We need at least two people, a reliable vehicle, and enough time to accurately gather data. Ideally we conduct these surveys every 10 years in both summer and winter, for each site. Compared to other research projects, road surveys are a good bang for the buck because they are relatively cheap to conduct but provide us with critical baseline data on a group of animals that are crucial to the health of our environment. In total, Hawk Mountain has conducted over 50 vulture surveys in 9 countries.

Many of you may be aware of the vulture crisis that has occurred in the Old World over the last two decades, but I’ll offer a reminder by first reviewing the numbers: out of the world’s 22 species of vultures, 16 are spread among Africa, Asia and Europe. 11 of these have recently become at risk for extinction in our lifetime. Some species have experienced a 99% decline since the late 1990’s.

With the combined effects of persecution, poisoning, drug-induced kidney failure, and harvesting for parts, the Old World has faced a fast-acting recipe for vulture disaster.

In Asia the primary cause of these mass die offs is a pain killer for cattle called Diclofenac that is ingested by vultures feeding on livestock carcasses.

In Africa the main threat is poisoning. In Europe, Diclofenac is still legal, and declines are anticipated if policy-makers don’t act quickly. There is a less harmful alternate drug available that offers the same therapeutic effects for a similar price, but so far, new legislation has not been passed.

Prior to the declines recorded in Asia and Africa there was no reliable baseline knowledge on the population size of affected species, meaning estimates of loss are likely conservative. Consequences from loss of vultures have included an increase in rabies cases due to a higher prevalence of wild dogs, as well as the spreading of diseases that were previously processed in the gut of these under-appreciated scavengers.

This is a perfectly heart breaking example of how human bias towards the most lovable species can sometimes harm those that float under the radar. To make this mistake once is somewhat forgivable. To make it twice is not.

This is why I believe Hawk Mountain’s vulture surveys are crucial. Vultures have been misunderstood and ignored, and while there have been commendable efforts to remedy this issue in Asia, Africa and Europe, we still have work to do in the Americas. We need to be proactive in deciphering how many vultures there are, fully understanding their role within our shared ecosystems, and proving their value to the public. Science alone cannot prepare us. The integrity of our future environment requires that we establish a culture of appreciation around vultures that will allow them a seat at the ecological table.

Okay, that’s the heavy part. Now, let’s focus on the fact that in the U.S., our vulture glass is half full. Our last survey resulted in a count of 979 vultures, between five routes in Georgia and Florida. Ten years ago, this same survey produced similar numbers, proving stability exists within that region. We continue to witness healthy numbers of black and turkey vultures throughout Pennsylvania and much of the eastern United States. This may not be the case in Central and South America, though our upcoming surveys in Costa Rica, Panama, and Argentina will hopefully add to our body of knowledge on population size and trends.   

On one of our final days in Florida, we spotted a group of vultures circling something yellow and indistinguishable. A scout landed and tore into whatever “it” was. After scanning with binoculars, exchanging excited hypotheses, and crossing a treacherous road, we discovered that the mysterious yellow “entrails” were no more than the sad remnants of a Happy Meal. This not only confirmed my suspicion that vultures are closet vegetable lovers but also reminded me that scavengers are adaptive problem-solvers. Black vultures in Central America drag coconuts into the middle of the road and wait for cars to pulverize them into a meal. We hear of crows and ravens using tools, eagles stealing fish from other birds, and raccoons breaking into, well…everything. Scavengers are scrappy, and vultures are no exception. This gives me hope that with support, they will adapt to our ever-changing human dominated environments.

As we watched the sun set behind the french fry frenzy, I felt optimistic that with continued monitoring my innovative feathered friends would have many more happy meals.  

Irruptions and Innovation

In 2007, Dr. JF Therrien deployed 12 transmitters on snowy owls on Bylot island in the Canadian Arctic. Snowy owls, like other raptors, can be difficult to monitor due to their territoriality and low densities. Arctic-breeding raptors typically establish nesting sites in remote locations, adding to the logistical dilemma of gaining insight into their life history traits, and the role they play within the Arctic ecosystem.

Satellite transmitters, citizen science, and long-term life history studies are extremely valuable tools that allow researchers to examine the movement ecology of birds, including snowy owls. Mixing and matching these tools can open doors to compelling scientific questions, and in the case of Therrien’s snowy owls, has resulted in papers covering a range of topics. New information on survival, reproduction rate, dispersal of adults, irruptions and winter movements are among recent Hawk Mountain publications that were made possible through this type of innovation. 

Two such papers were led by former conservation science trainees, in collaboration with others, including Dr. JF Therrien. These papers delved into the mystery of snowy owl irruptions, defined as the “massive movement of individuals over large distances, associated with large fluctuations in food supply.” Some of us have been lucky enough to see a snowy owl in Pennsylvania, on those rare winters when the birds venture further south than usual. I myself drove two hours to catch a glimpse, and I will never forget the sight of that owl hunkered down in the middle of a field, glittering in evening light. As I drove away, I couldn’t help but wonder; what brings them here?

Two primary hypotheses have been proposed to explain irruptions; the “lack-of-food” hypothesis suggests that snowy owls leave their normal wintering grounds because of food shortage in certain years. This implies that the snowy owls we see in Pennsylvania should be in poor shape, and likely close to starving. The alternative “breeding success” hypothesis instead links irruptive movements to a surplus of food on the breeding grounds.

Snowy owls specialize in lemmings, a prey resource that occurs in pulses, due to their population dynamics. One year there may be a plethora of lemmings scurrying around the tundra, the next year very few, due to high predation and other factors. Lots of lemmings means lots of chicks, which means lots more owls. The breeding success hypothesis implies that the reason we see snowies in Pennsylvania is because following a high lemming year, there are so many owls dispersing at the end of the summer that some young birds push south.

To add depth to our knowledge of irruptions, Teja Curk, a conservation trainee from 2016, assessed the body condition (mass relative to size) of snowy owls during both irruptive and “regular” years. Teja assessed body condition of snowies on both regular (Great Plains) and irregular (Northeaster North America) wintering grounds, to see whether the birds we see during irruptive years are, in fact, starving. She found that most owls (male, female, juvenile and adult) were in good shape during irruptive years and even discovered that body condition was better on the bird’s irregular wintering grounds. “Good shape” in this context varies depending on sex and age of the bird, however less than 2% of the owls approached the weight threshold that would deem them a starving bird. Her results provide support for the breeding success hypothesis.

Pablo Santonja and Irene Mestre, trainees from 2015, looked specifically at the age of the birds found south during irruptive years. Their results supported the same hypothesis, showing that the majority of owls (up to 90%) seen in eastern North America are juvenile birds, meaning they are less than 1 year of age. As with some other migratory species, the more dominant birds within a population don’t move as far. Adult snowy owls often out-compete young birds, so it makes sense that in a year where adults are laying up to 11 eggs, some of those young owls will need to leave to avoid competition from more successful, experienced adults.

This leads to an interesting point: perhaps these two competing hypotheses are not, as Teja notes in her paper, mutually exclusive. After a highly productive lemming year, many lemmings will be eaten due to a surge in predator numbers, and therefore the next year could produce low lemming numbers. If this happens, snowy owls could be forced to look elsewhere for food. So, it turns out, that both a surplus of food and a lack of food seem to play a role in the patterns of movement among snowy owl populations.

If you ask me, these papers are a beautiful example of the scientific method at work; formulating ideas, testing those ideas, and polishing the conclusions in pursuit of certainty. Hats off to our trainees and their collaborators for hard work and intriguing findings. Teja is currently at the Max Planck Institute for Ornithology in Germany pursuing a PhD. Pablo is living in Spain, and Irene is now returning from three years in Australia.

Both of these papers utilized a data set resulting from a 25 year-long study in which live snowy owls were weighed, sexed, and aged. Christmas Bird Count (CBC) was also a valuable asset in both studies. For those of you unfamiliar with CBC, every winter thousands of volunteers gather together on the same day, collecting bird records within a territory and submitting them to a database that provides an impressive summary of which birds were seen, where, and how many. These papers demonstrate the utility of both citizen science and long-term studies, and in a rapidly changing world, this cross-pollination of resources is critical. We are very proud of our trainees for their hard work, and grateful to citizen scientists around the globe who give their time to participate in the expansion of our raptor knowledge.

Gaining a holistic understanding of an ecosystem requires acknowledgment of moving parts within, not separate from, the whole. Hawk Mountain’s research is part of several collaborative efforts to better understand the role of snowy owls within the big picture, including Project SNOWstorm and the Bylot Island Ecological Studies and Environmental Monitoring.  

Future projects will include building a model that combines reproductive and mortality rates to assess population trends of snowy owls. This past August, three transmitters were deployed on chicks before they left their breeding grounds. Investigating the movement patterns of these birds will hopefully allow for a comparative look at owls throughout the Eastern tundra, Western tundra, and those in between.

Trainee to International Conservation Pioneer

Hawk Mountain Sanctuary

The cinereous vulture was extinct in Portugal as a breeding species at the end of the 20th century, but in 2010 a new colony was established in Tejo Internacional National Park, in the eastern limit of the country and close to the border with Spain.

This colony now hosts 18 breeding pairs, and no studies were done before out of the annual breeding monitoring implemented by the Natural Park’s staff. Due to this lack of information, and being the main population in Portugal, our goal is to get information about the dynamic of this colony. Thus, the first step is to study the juvenile dispersion and the potential causes of mortality of this population.

During the summer of 2018, eight nestlings were tagged with GPS-GSM transmitters, supported by Hawk Mountain Sanctuary and the Spanish electric company ENDESA. This support will continue during 2019, with the goal to increase the number of birds in this study and to get more accurate and representative information.

All this information will be shared with the Natural Park’s managers, with the objective to facilitate them the conservation and management of the colony, since all the nests of this colony are in private estates inside the protected area.

But how did HMS reach Portugal? During 2009, I was at Hawk Mountain as a trainee. I was an enthusiast in vultures’ conservation, and HMS offered to me the amazing opportunity to trap turkey vultures and to use wing tags for the first time in my life. But for me, the most impressive was to get access, for the first time in my life, to the huge amount of information about raptors in the Sanctuary library. I spent many days reading papers and copying a lot of info to bring with me after my traineeship. From that time, I was interested in vultures’ juvenile dispersion but never had the opportunity to be involved in a project with this objective.

And again, after almost a decade, a causality joints me one more time to HMS, but this time in Portugal, not in Pennsylvania.

In this new cinereous vulture’s project, HMS is more than a sponsor offering GPS devices. From the beginning of the proposal to HMS, its permanent support and fast reply have encouraged me to work in this project, especially during the hard times of preparations, authorizations, organization, etc. I am sure that the presence of HMS in the project has been a motivation to other bodies to participate and be part of it. The result has been the creation of a task force, where raptor conservation and research organizations such as HMS, a private company such as the Spanish electric company ENDESA, and the government of Portugal, are in a narrow collaboration to study and protect the cinereous vulture in this colony.

Now, with the vultures sending throughout the transmitters lots of daily data, it is time to enjoy learning how these vultures move around the Iberian Peninsula and, who knows, maybe one of them cross the Gibraltar strait toward Africa and offer us new and unexpected information about the movements of this species to sub-Sahara regions!

 On October 23, assistant professor Allison Cornell visited Hawk Mountain from Cedar Crest College to provide a seminar on the physiology of developing American kestrels, emphasizing the role of the Sanctuary’s nest box program in her research. Collaboration between Dr. Cornell and Dr. JF Therrien, senior biologist at Hawk Mountain, began in 2017 and has resulted in exciting science concerning a widely-appreciated falcon species that has been experiencing declines nation-wide.  

 In her seminar, Dr. Cornell highlighted the importance of an integrative approach to understanding the ecological context of a species, stating a cherished quote of hers:

 Behavior is observed physiology.
— Vincent Dethier.
Life History Diagram

 As a physiologist, Dr. Cornell’s methods include the assessment of internal as well as external factors that could influence the survival and overall condition of developing birds. Her past work has included assessing the relationships between nestling condition and oxygen storage capacity and identifying how factors such as timing of breeding are related to developmental cues in starling chicks. This type of research adds color to the bigger ecological picture, allowing us to learn more about why birds exhibit the behaviors they do, and how this relates to their overall survival. Factors like pectoral muscle mass, aerobic capacity, red blood cell count, and wing area are just a few telling descriptors that can shed light on what prepares a bird to leave the nest. Turns out, there’s more to it then being kicked out by your parents! 

 For Dr. Cornell, Hawk Mountain’s kestrel nest box program has been instrumental to the success of her research. Nest boxes provide an opportunity to observe kestrel development in a natural setting rather than in a lab where results can be compromised by the lack of true environmental influences. In addition, the nest box program has done the ground work of establishing relationships with landowners, which allows for Dr. Cornell’s research to be conducted in a kestrel-friendly culture.

 Hawk Mountain sees immense value in partnering with an experienced researcher who has the time and passion for conducting good-quality science using Hawk Mountain’s long term data set and putting in the field time to monitor boxes. In addition, trainees and students from both sites are benefiting from the academic opportunities included in this project. Mercy Melo, a student at Cedar Crest, and Jen Houtz, a former conservation science trainee, are both currently involved in the work with Dr. Cornell.

Through the deployment of nest cams and this thorough approach to ecology, Dr. Cornell has given students access to several thought-provoking research topics, including how physiology traits change across nesting period and whether “dead beat” falcon dads have an impact on the physiology of their young. This work has the potential to fill information gaps and provide necessary context to the kestrel decline.

 Collaboration between Hawk Mountain Sanctuary and Cedar Crest College has opened doors to new research, and has also given young professionals the chance to step into raptor ecology with resources that are not always easy to come by: a long term data set, accessible observation sites, and supportive advisors from neighboring institutions. This is a clear win-win for raptor conservation and one that Hawk Mountain is thrilled to be a part of.

Hiking up to North Lookout on my first day, as a summer education intern, wasn’t the first time I made that journey. It probably wasn’t even the 10th time. I have been able to make the journey countless times because I am lucky enough to call Hawk Mountain Sanctuary my backyard. Since I live in the small town of New Ringgold that you can see from North Lookout, Hawk Mountain is no stranger to me.

Yet, this summer, I got to make the drive up Hawk Mountain Road everyday to experience this place from a whole new perspective. Being the “local” intern this summer, I was already aware of the River of Rocks bolder fields and the incredible views from the lookouts. However, I wasn’t aware of the world-class research that goes on at Hawk Mountain Sanctuary. From the Farmland Raptor Project to working globally with other scientists to butterfly migration to educating kids, this special place that I have grown up going to my whole life is the leader in all the techniques and practices I have been studying while at West Virginia University.

Even though I was technically an education intern, I was always being invited to help tag black vultures or band American kestrels with the conservation scientist and trainees. There are some things that can’t be taught in a classroom, and getting to work along biologists at Hawk Mountain, such as J.F. Therrien, Laurie Goodrich, and David Barber, were some of those experiences. Since all the biologists and researchers at the Sanctuary have expertise in different fields of study, I felt lucky to have been able to have conversations with each of them about what they are accomplishing.

As an education intern, I spent most of my time working on the top of the mountain, leading excursions with groups of all ages and from all different backgrounds. Being able to share your knowledge and passion for conservation with children and adults, who may live in cities or might not know about the power of preservation of raptors, other wildlife, and ecosystems found in the Appalachian area, is the greatest feeling. You can learn a lot from mistakes you make. Watching the way that educators Erin Brown, Rachel Taras, Andrea Ambrose, and Jamie Dawson work with kids and through kids taught me about how I aspire to be as an educator.

Hawk Mountain has taught me how to work with a community of scientists and educators from various backgrounds. This notable place has provided me with an immense amount of hands-on research and fieldwork, and it reminds me every day why I study and strive to be a better scientist and educator. I have been so fortunate to work at a place that my 10-year-old self would visit on those fall days to watch the migrating birds with my school group. I never would have anticipated that I would have a chance to work at a place that I have always considered my home among the hills.

Searching for Two Secretive Forest-Raptors

By Lauren Sarnese, Goshawk and Broadwing Project Field Assistant 2018
Hawk Mountain Sanctuary

Working on the Pennsylvania Goshawk and Broad-winged Hawk projects has given me a whole new set of experiences and has opened my eyes to a different sector of field work. My degree is in biology with a personal focus in entomology from East Stroudsburg University (Spring 2016). Coming into this, I had no experience with raptors, but I did come with enthusiasm, passion, and a general love for ecology.

It began with sifting through gear lent to me by Hawk Mountain—a plethora of technical resources mixed with lists of places and names I had never heard before. Dr. Laurie Goodrich and Rebecca McCabe helped prepare us for the upcoming field season with a training session at the Sanctuary. I took notes and wrote down names and dates in preparation to make calls and schedule site visits for the upcoming weeks. As the end of March approached, I was eager to get out in the field and start searching for these raptors.  

searching along the creek.jpg

The field season began with nest-searching for northern goshawks. Being inexperienced, I was pointing out squirrels’ nests, insignificant stick clusters, and nests that I now know would crumble under the weight of a goshawk. Over time, I developed an eye for large nests, large birds, and an ear for raptors (and maybe a few passerines). The work always gave me more energy than it took from me, which is how I classify a passion. It became increasingly more exciting with each new thing I saw; I became hyper-focused when looking for nests and listening for raptors.

The first day conducting goshawk broadcast surveys was wonderful and challenging! As to be expected for the northern part of the Pocono Mountains, the terrain was rough. The surveys were interesting in a way that they challenged you to pay attention to all visual and aural details of your surroundings in a fixed period of time. The anticipation was much like fishing: you don’t know if you’ll catch anything, but if you do, it’s a stellar day! This mindset persisted and carried us through the rough terrain, and there was only a minor mishap of accidentally spraying my former professor with bear spray.

However, at the fourth broadcast point (a total of 19 were done at each historical site), we got a response. That initial callback gave us all an electric amount of energy; this was what being in the field was about! We continued forward in hopes of crossing paths with this elusive creature that I had yet to see. We played more calls but those few responses were all we were fortunate enough to hear that day. The excitement was still overflowing as we finished the survey and walked to the car anxious to call Laurie. She, being equally as excited, immediately reached out to Chelsea, a Penn State graduate student overseeing goshawk surveys statewide, who instructed us to schedule another day of searching at that site.

During the time of Goshawk broadcast surveys, I also began searching for broad- winged hawk nests in the Delaware State Forest. This was definitely a learning curve for me. Spotting a broad-winged hawk female on the nest was more difficult than I anticipated. She would hunker down only looking at me with one eye. If you were lucky, her tail might have been sticking out of the nest too. The broad-winged hawks were equally as exciting and easier to find than the goshawks. I found myself attempting to anticipate their movements, so I could track them back to their nests in hopes of finding a female incubating.  

 Working on both projects, I gained so many unique skills that will carry me through my career as a biologist. I developed relationships with foresters, private landowners, and, of course, the wonderful team at Hawk Mountain. I am so grateful to have had the opportunity to work with such a fantastic organization and team. I look forward to seeing all of the ecological advancements they make in the future.

Monitoring Migration in Eilat, Israel

By Ana De Osma Vargas-Machuca, Autumn 2016 Conservation Science Trainee
Hawk Mountain Sanctuary

A month ago I came back home from my Israeli adventure, where I have been monitoring the spring raptor migration in Eilat, a dream came true.

This all began in 2011, when I met Re'a Shaish while volunteering in the Migres Program in Tarifa, Spain. He is an Israeli guy who was extremely passionate about birds, and at only 19 years old was able to identify every single species of raptors flying over us. He told us about Eilat and the migration there, and since that moment Eilat had been always on my mind.

Last year we met again in Extremadura for a couple of days, where he was assisting Yoav Perlman with his field work, and both of them told me again about the spring migration in Eilat. I was working as a biologist in Spain, but it wasn't anything related to conservation biology. I greatly missed being in the field, so at the end of the year I arranged to be off from work in the spring and contacted Noam Weiss (the director of the IBRCE) to apply for a position as a counter in the raptor team. When I got his reply telling me that I was accepted, I was elated.

So there I was at the end of January, flying to Eilat, watching through the window the beautiful Negev desert, getting goosebumps and feeling excited for all of the experiences to come.

Counter station in the Eilat Mountains.

We were two teams of volunteers: the raptor counters, working mainly at the stations in the mountains, and the ringers and guides, working at the sanctuary.

The first of February was the first day of the count. The count was conducted by four of us (Daniel, from UK; Gaidis from Latvia, Ragnar from Denmark, and myself), divided in two stations, Low Mt. and High Mt. Station, both of them in the Eilat mountains, close to the Egypt border.

At the beginning of the season, the migration was still very low, so those not counting would have the chance to go to the sanctuary to assist with other work or to just bird around. I remember the first day being at High Mt., and even if I had no birds migrating, I felt so grateful for just having the chance of being there, in such a beautiful office, with Jordan on the east, the Red Sea and Saudi Arabia in the south and Egypt in the west.

Some brown-necked ravens, Tristam's starlings, two dessert larks, a hooded wheatear, and a very nice juvenile white crowned wheatear were our regular visitors who sat at the station and kept us company. On those days of counting steppe eagles in February, there were some amazing days with birds flying overhead, very close to us. Such incredible creatures in that stunning landscape... I was happy no matter what weather I had, how many eagles were migrating or how many people visiting; being there was just amazing.

In February we would finish work before sunset and still have time to go to the beach for some snorkeling before the light was gone. We lived in the Field School, right in front of the beach near the Taba border with Egypt, so coming back home from the mountains and walking to the beach with the guys for some snorkeling was our daily afternoon routine. We found some spots with well-protected coral reef and snorkeling there with all of those beautiful fish was delightful.

First week of March, I was selected together with Anton (a Danish ringer) and Ohad (Israeli birdwatcher) to be part of the Arabian warbler survey taking part in the Arava Valley, close to Hatzeva (2 hours north to Eilat). This survey was very important, as there is very little information about the species, and the first and last survey was on the 1980, conducted by the SPNI. We walked around 10-15 km everyday in the desert, looking for Arabian warbler territories but also recording every bird species around, but this incredible opportunity of going where few have had the chance to go felt like a holiday. It was really special to be surrounded by that nature, and at the same time to know that we were making an impact for the species.  We actually found more new territories than they were expecting, and I feel very thankful to Noam, Inbar, and Eli for letting me be part of this.

The rest of March flew by, and the migration came to peak time. Steppe buzzards, black kites, black storks together with other species started to pack the skies. Days became longer, counting from sunrise to sunset. It was exciting and exhausting at the same time, but we were happy no matter how tired we were; having those numbers of raptors migrating in front of you gives the energy you need to keep clicking and counting. And that's what we did until the 10th of April when we completed the count.  From the 12th -14th of April we were part of the Raptor breeding survey, and we finished work the 15th.

After that I went traveling around the country, spending most of the time enjoying the north (Hermon mountain, Golan Heights, Hula Valley), and it was so different from the desert I had worked in. I returned to Spain at the end of April.

It's difficult to summarize in a post a 3-month experience, so I hope at least I gave you a brief feeling of how it was. Not everything was just work, there were also days off, and I spent most of them going hiking in the Eilat mountains, where there was much to explore and see.

Israel is a beautiful country with very warm and welcoming people, and felt at home from the start. Thanks to everyone who made this experience so amazing for me: my teammates, all of the special people that stop by High Mt. station, Frank and his lovely company, Libi and Tdazok, but specially Noam and my good friend Re'a; without them none of this would have happened. 

Shalom!
