JHWF Board Member Bruce Pasfield tries to get an accurate count of Trumpeter Swans on the stretch of Flat Creek within the National Elk Refuge.
Temperatures never rose above zero during the 2016 Christmas Bird Count on December 17, but it was filled with the warmth of a wonderful tradition and the thrill of joyful interaction with the birds of winter.
According to Bert Raynes, the Jackson Hole Christmas Bird Count “got started 60 years ago and covered mostly good bird spots in and around the Murie Ranch near Moose. The counters were a plucky but small group, including Olaus and Adolph Murie and presumably their wives and some other locals.” The Audubon Society sponsors more than 2,500 annual international censuses of birds in North and South America at year-end. Susan Marsh organizes our local count and animates it with her nature-loving spirit.
The Jackson Hole Wildlife Foundation sent a team of two staff members (Kate Gersh and Jon Mobeck) and a board member (Bruce Pasfield) out into the field to join the count. Fueled by a good breakfast and conversation with fellow counters at Bubba’s, “Team Goldeneye” got on the board early with a Northern Shrike observation just below the National Museum of Wildlife Art. Driving along the highway north out of town, the team spotted several Common Ravens and viewed ten Trumpeter Swans beyond the dry rushes on a stretch of Flat Creek’s open water.
Moving farther north, “Team Goldeneye” stopped at the Fish Hatchery Pond to record waterfowl amid the fog from the frigid water. Here, the first six of 17 Barrow’s Goldeneyes introduced themselves along with 10 Mallards and a pair of Common Mergansers. While binoculars were set down for a moment to allow fingers to thaw, a Bald Eagle flew high above the pond eastward toward the Sleeping Indian, the first of three Bald Eagle observations. Let us not forget to mention the five Buffleheads we saw at the pond before piling back into the car. A curiously wandering crew, “Team Goldeneye” zipped past the Gros Ventre Junction for a short distance before circling back. While cruising just outside of its territory, Pasfield spotted some wings flapping in the sagebrush. Just as the one bird was definitely recorded as a Greater Sage Grouse, a flock of another 24 descended onto the flats to hide in the sage nearby. A beautiful sight!
The Jackson Hole Christmas Bird Count is a terrific holiday tradition, punctuated by a passionate cast of friendly characters who love to follow birds around the valley. The Jackson Hole Wildlife Foundation is grateful for each of them, and honored to have shared in the experience with many members of the Nature Mapping Jackson Hole family.

JHWF ED Jon Mobeck presents on the artistry of citizen science and the conservation legacy informing Nature Mapping Jackson Hole.
Earlier this month the University of Wyoming Biodiversity Institute hosted the first ever Wyoming Citizen Science Conference in Lander. Several representatives from the Jackson Hole Wildlife Foundation (JHWF) and Nature Mapping Jackson Hole (NMJH) attended the conference with the aim of learning from other citizen science practitioners across the state and of sharing what we have learned from the past eight years of running our program. The conference proved to be very valuable.
The variety of citizen science programs represented was immense and indicative of the breadth and depth available in Wyoming. For example, modeled on NMJH, Laramie sponsors both a winter and summer “Moose Day” with up to 38 transects and over 80 volunteers. Rocky Mountain Amphibian Project conducted a survey of chytrid fungus in frogs and toads throughout the state, including Teton County. A PhD student studied how geo-tagged imagery can enhance surveys by providing follow-up ID, unbiased assessments, and long-term documentation of plants and animals. Museums around the country are recruiting citizen scientists to review historical specimens, including label information on University of Wyoming herbarium sheets. Road Scholar (formerly Elderhostel) volunteers are chronicling archaeological sites in the Wind River Mountains. Associated with the North American Butterfly Association, twenty citizen scientists have tracked approximately 28 species of butterflies in a count circle in Lander for a decade. These are only a few of the amazing projects presented.
The core focus of the conference was on the problems and solutions that citizen science program managers and volunteers face. Several speakers talked about the difficulty of designing data sheets that capture essential information while also being user–friendly. Project directors need to enter and analyze data relatively quickly to keep citizen scientists engaged: volunteers are rewarded by seeing results of their work. Social occasions help build a concerned community. While ensuring quality remains challenging, with sufficient training citizen scientists produce solid scientific data. For instance, the Rocky Mountain Amphibian Project compared the quality of data collected by volunteers vs. bio-techs with very similar results. In short, presenters concluded, “Citizen scientists rock!” And we have a lot to learn from each other.
Our role in the conference:
On the whole, 65 conference participants came from across Wyoming, and even Idaho and Vermont too – all from a mix of individual citizen scientists, nonprofit organizations, primary and higher educational institutions and federal agencies.
JHWF was a silver-level sponsor for the Wyoming Citizen Science Conference, and our Associate Director Kate Gersh served on the program planning committee, which helped select presenters and set the agenda. Over the course of nearly two full days, here are a few programs that were presented by JHWF board, staff, and partners:
- “Lessons Learned: Eight Years of a Citizen Science Program in Jackson Hole” – Aly Courtemanch
- “Values Driving Conservation: Citizen Science as Interactive Art” – Jon Mobeck
- “Fundraising for Citizen Science: Experiences and Advice” – Kate Gersh, Anya Tyson, Wendy Estes-Zumpf, Frances Clark (in absence)
- Poster Presentation: Nature Mapping Jackson Hole: Mapping Community Solutions ̶ Kate Gersh
- Poster Presentation: Monitoring Wildlife Crossings on South Highway 89 ̶ Paul Hood
- “Bringing Citizen Science into the Backcountry: Emerging Best Practices to Engage Outdoor Education Organizations” – Anya Tyson
- Screening of Far Afield: A Conservation Love Story
Importantly, one of NMJH’s lead volunteers Tim Griffith attended the conference and contributed much to the conversation. Based on the latter and the abovementioned, we believe we successfully expanded awareness of Nature Mapping Jackson Hole statewide and regionally, thereby opening opportunities for greater community connections. This was a proud experience for us and we feel honored to have represented on behalf of everyone who has been involved with NMJH.
Next steps for Citizen Science
What comes next? Well, based on survey responses, conference participants have expressed a desire for open communication and collaboration between citizen science groups, as well as, one central location to list project information. The Biodiversity Institute is excited to share that they have begun the process of planning a website to act as a citizen science clearing house. It will provide a forum for discussion around citizen science projects in our region and to glean tips and ideas for best practice. It will also help to incorporate our projects into the classroom. In addition, the idea of a dedicated newsletter for citizen science groups in Wyoming is under discussion.
The hope is that this conference will take place again next year, giving us the opportunity to follow-up on tactics and ideas that were shared. We have much to learn still about volunteer recruitment and retention, fundraising, risk management, data collection and submission, data sharing and dissemination, evaluation and the list goes on. JHWF will be sure to keep you updated on new developments as they come about. Stay tuned as we continue to explore the potential of all that Nature Mapping Jackson Hole has to offer!

One of the perks of working for the Jackson Hole Wildlife Foundation is that occasionally you get invited by local scientists to do really, really cool stuff! Case in point, this past weekend staff traveled into the Gros Ventre Range with a crew of researchers to briefly capture, study and release bighorn sheep. Witnessing a small helicopter carrying blindfolded, restrained sheep at one or two at a time is very cool! This might sound alarming to some, that sheep would be transported from location to location via helicopter, but be assured that the animals are caught in the shortest possible time, with the least amount of stress. Furthermore, the purpose for this “trip of a lifetime” is to conduct science that will ensure the long-term survival of this iconic species of the American West.
The helicopter brings in two bighorn sheep for a gentle landing.
The Wyoming Game and Fish Department (WGFD) is continuing its multi-year research project on bighorn sheep in the Jackson Region. On December 10 and 11, 2016, 10 female bighorn sheep (previously fitted with radio collars) were captured for disease testing in an effort to learn more about their survival and migration patterns. Samples were collected to test for respiratory pathogens that can cause pneumonia. In addition, researchers from Dr. Kevin Monteith’s lab at Wyoming Cooperative Fish and Wildlife Research Unit at the University of Wyoming performed an ultrasound on each animal to measure body fat. This is a three-year study evaluating how body condition is related to pneumonia outbreaks.
The Jackson herd, which numbered 500 animals in the 1990s, has experienced two significant die-offs in recent years. In 2001, it was estimated that as many as 50% was lost due to a pneumonia outbreak and another estimated 30% lost again in 2011. Today it is estimated that the Jackson herd has climbed back to around 425 animals currently.
Kate Gersh and Greater Yellowstone Coalition wildlife program coordinator Chris Colligan assist the research team.
By monitoring individual female bighorn sheep (ewes) through time, researchers are assessing nutritional condition, pneumonia infection, and linking those data to reproductive performance, survival, and nutritional condition in subsequent seasons. At a minimum, they hope to begin to shed light on the complex interactions in the population dynamics of bighorn sheep and help identify possible management alternatives to reduce probability of pneumonia die-offs. For this specific research project, approximately 20 ewes have been collared. During the first three years of this project, biologists are expecting to recapture these same individual sheep each spring and fall to perform the same round of tests and evaluations. The team will go out again in March 2017, and attempt to catch more of their collared ewes to ascertain pregnancy and other health conditions.
JHWF staff is grateful to have been included in this project over the weekend and we thank the WGFD and Wyoming Cooperative Fish and Wildlife Research Unit for allowing us to see first-hand the efforts involved in conducting field research on bighorn sheep. We also thank all those involved for continuing to support wild sheep conservation efforts — you are doing excellent work!

Eagle Scout is the highest achievement or rank attainable in the Boy Scouting program of the Boy Scouts of America. The requirements necessary to achieve this rank take years to fulfill, and must include completion of an extensive service project that the Scout plans, organizes, leads, and manages. Luckily for the Jackson Hole Wildlife Foundation, prospective Eagle Scout Maclain Smith from Utah, made us the beneficiary of his service project. This past Friday afternoon, Maclain came up to Jackson to install 52 Mountain bluebird nestboxes that he and fellow Scouts constructed by hand.
With lots of laughs and great spirit, Maclain and nine of his family members spent a sunny autumn afternoon installing new pinewood nestboxes on half of our Mountain bluebird trail that runs along the western boundary of the National Elk Refuge. Our old nestboxes (that served their purpose for 13 years!) were taken to Teton Recycling Center where they will be repurposed into wood mulch and used for gardening and landscaping purposes. After 13 years, we felt it time to retire the old nestboxes as they had seen many repairs over the years, but their deteriorating condition was starting to present challenges in terms of predator control and protecting nests from bad weather conditions.
Not only are we fortunate to have the help of Maclain, but we currently have two more prospective Eagle Scouts producing a total of 72 additional nestboxes that will be installed this coming spring. Of these 72 — the other half of our trail will receive 52 new nestboxes, we are looking into placing additional nestboxes elsewhere on the National Elk Refuge, and keep a few in storage. Thank goodness for Scouts!

Registration is now open for the first ever Wyoming Citizen Science Conference! Hosted by the UW Biodiversity Institute, the conference will involve keynote and breakout sessions that guide program managers and citizen science participants (teachers, Scout leaders, community activists, etc.) to weigh in on what works well (and what doesn’t) in terms of having a successful, impactful citizen science program. The conference will be held in Lander, Wyoming, on December 1-2, 2016, and with an optional day on Saturday, December 3 to attend focused workshops.
We hope you can join us. The Jackson Hole Wildlife Foundation will be in attendance to represent Nature Mapping Jackson Hole – delivering two oral presentations and presenting two project posters in addition to, screening the film Far Afield. We’ll mainly be talking about lessons learned from the past eight years of Nature Mapping Jackson Hole, sharing our experiences and intending to learn much from others in attendance that will come from across the state. The organizers of this inaugural event hope to have a strong representation from active citizen scientists, not just those serving in professional capacities. Register today and come learn, share and be inspired!
Details on the conference agenda can be found here.

Hiking under Engelmann spruce trees has been hazardous this fall. Light brown cones, 4-6 inches long and sticky with pitch, pour down amidst harsh chattering from above. I have counted one cone falling every 3-5 seconds, another time I couldn’t keep track of the barrage. Cones landed on my head, bounced and then lay strewn about my feet. Cone storms. What s going on?
Red squirrels are taking advantage of a “mast year.” Last spring, you may remember, prodigious amounts of pollen wafted on the wind. Some of that pollen landed on tiny female cones, which have matured, securing two winged seeds under each scale. Spruce trees are now laden with dangling cones from the top down. This abundance occurs every 2-3 years in spruce. The intervening times are lean.
Well adapted to feast and famine, red squirrels form large middens—stores of thousands of cones. They efficiently sample and then harvest trees with the most seed energy per cone and with the greatest cone abundance. Middens lie at the center of the most productive group of trees.
A midden can best be described as several inches of cone scales and cores heaped over mineral soil, forming mounds up to several feet high and wide. The loose surface often has shallow holes in it. In the mineral soil below, there may be a network of tunnels. Squirrels pack several cones, pointed end down, into holes which will be covered eventually by more scales and cores. In this cool and moist environment—a humidor—cones will remain unopened for at least 1-2 seasons until the squirrels retrieve them. When they do, squirrels eat cones like corn-on-the-cob, scattering scales everywhere while consuming the nutritious seeds. It has been calculated that squirrels consume 50-156 cones a day and stash 10s of 1000s in a midden in a good year. No wonder red squirrels are so territorial – chattering loudly at any perceived threat and dashing out to their territorial boundary: they are defending their stash for winter survival.
While cones are preferred, in lean times and in summer, red squirrels will eat other items. Fungi are particularly relished, with parts hung up in trees to dry. They eat buds, fruits, sap, even cambium and phloem, as well as eggs and insects. Small plant parts placed in middens may help train young squirrels for future hoarding. In different years, squirrels may harvest cones of Douglas firs – which have mast years every 4-5 years, or as back up, serotinous cones of lodgepole pine. Lodgepole pine cones are often gathered on top of middens. They do not open even when dry, are too tough for other predators to eat, and seeds remain viable for years. The squirrels don’t need to spend extra energy to bury them.
The other day, walking around Moose Ponds, I heard several red squirrels churring within a stand of battered old spruce and fir trees. Their density indicated good habitat. Tangles of downed limbs and saplings surrounded straight, scaly boles clad in densely needled branches, which intertwined to form a closed, irregular canopy. Engelmann Spruce reach peak production at 150-200 years and provide diverse cover, escape routes, and nesting sites. Old growth trees are excellent for red squirrels.
As red squirrels are active all winter, nesting sites are vital for thermal regulation. Tree squirrels prefer natural cavities, but these are often in short supply so instead squirrels will build a nest of leaves and grass 12 to 60 feet off the ground. Other options include “witches brooms,” an aberrant growth pattern where twigs are unusually dense. They will also burrow into tunnels under their middens for warmth and safety.
Nest sites are located within 100 feet of larders so squirrels can readily defend and retrieve their stores. Circular territories may be 1-2 acres centered around a midden. I nature mapped six squirrels – six territories – on my route past Moose Ponds. While dutiful, I wish now I had taken more time in this rough old patch of forest to see where the middens and nests might be.
Predators come from air or ground. Squirrels may have different calls depending on whether or not a threat is aerial or terrestrial. One study indicates that red squirrels produce a high frequency, short “seet” sound similar to alarm calls of birds. This sound is hard for raptors, such as Goshawk, Great Horned Owl, or Red-tail Hawk , to locate or even hear. A louder bark call is used for overland threats, such as a Pacific (pine) marten (12-20% of marten diet is red squirrels), weasels, or fox. Once alerted, squirrels scramble and hide in dense vegetation.
Between predation and starvation, only 25% of squirrels survive into their second year. Females are in estrus for one day only in early spring. Many males, one dominant in the lead, will give chase and several may succeed in copulation on that one day. In just over a month, the female gives birth to an average of four young which will be independent in another 70 days, by early fall. While mothers may share a territory with daughters, they kick out sons who must then find and defend their own territories by winter. Often the most successful males have ventured the farthest to find a relatively large territory containing an abandoned midden. Midden sites are often used by many generations. In autumn, youngsters and seasoned squirrels are particularly territorial, defending boundaries while gathering cones, which is why they are so vociferous.
Red Squirrels are the most frequently Nature Mapped small mammal with 305 observations over the last seven years. Even so, many of us pass them by – unrecorded – on our hikes. In your next excursions through a conifer forest, listen for chatter. Can you hear differences in their calls? Can you discover a midden nearby? Does a squirrel bound toward you to defend its territory or scurry up a tree or down into a tunnel to escape? Can you find its nest? All these behaviors are fascinating to watch while you may, or may not, log a new Nature Mapping observation.
