A valiant cadre of over 95 volunteers ventured out on a frigid morning to scout for moose with great accomplishment. The latest count, still to be verified, is 94 moose. This compares well with Moose Day 2021 when 109 volunteers recorded 106 moose. Thank you intrepid surveyors, gracious landowners who granted permission to survey, and moose who turned up to be counted.
Cold
The dominant sense of the day was cold! Temperatures were gauged at -20F west of the Tetons and at the north end of the park at 7 a.m. when many of you set out to make your route. Temperatures barely made it into the single digits by noon time. (Moose don’t mind this cold.)
However, while some of you were at first daunted by the cold, you persevered, and as one skier said, “Soon we were stripping off jackets once we warmed up.” Another commented on the balancing benefit of a classic “blue bird” sky day. Morgan Graham, a veteran of all Moose Days, said this is the coldest he recalls for a Moose Day. “Blizzards yes, but not this cold!”
Participants: Dozens of teams spread out to the north end of Grand Teton National Park by Swan Lake, south past Hoback, and east up the Gros Ventre. For the first time, eight teams ventured up the canyons on the west side of the Tetons. Your observations will help determine which areas should be added to our Moose Day Survey.
We also had long-time valley residents participate: Dornans, Ewings, Barkers, and Linns. Gene Linn’s grandchildren were keeping their eyes open for moose in Wilson and found two! These families have been advocates for wildlife for generations.
In total, you hardy Nature Mappers and other Moose Day volunteers spent 186 hours skiing, snowshoeing, walking, and snowmobiling. Other sets of volunteers drove slowly through neighborhoods in and around Jackson and Wilson peering behind buildings, across fields, and into willow thickets for another 160 hours. Total “effort” was over 350 hours in one morning!
Where were the moose?
While about half the teams were disappointed, others found moose. Almost half of the total moose were discovered in a just few areas (see map attached)
Coordinated by Ashley Eagan, the USFS team of four spent much of the day snowmobiling east up the Gros Ventre. They found 20 moose! Sarah Dewey and Carson Butler, biologists with GTNP, spent five hours finding 14 moose east of Moran (not yet mapped). These have been traditional sites for moose, likely because of large willow stands and limited disturbance.
A large team on skis and by car covered Kelly and the park roads north of town and found only a few moose. Last year this large team had 19 moose between Kelly and the rotary. Moose seemed to have moved west into the vicinity of the JH Golf and Tennis Club where a multi-modal team led by Randy Reedy scored 11 moose.
Many teams scoured smaller territories in and around Jackson and Wilson. As in past years, Wilson harbored a strong scattering of twig eaters in the lowlands with extensive willow cover. Sightings extended south down the dike and Fall Creek Road around Crescent H. Those who covered the buttes had great views but no moose, nor were any of the large ungulates seen around Hoback, Astoria Hot Springs, or Snake River Sporting club.
Other wildlife observations: Many did not see moose, but Nature Mapped other critters. In the north of the park, skiers detected an otter slide, evidence of wolves on a carcass, a pair of bald eagles and particularly unusual a golden eagle. Fifteen bison were grazing near Kelly. Nathan Letcher spied coyotes on the Elk Refuge.
Along Fish Creek in Wilson, mergansers, mallards, barrow’s golden-eyes by the dozens and four trumpeter swans were feeding in the waters, with two whitetail deer along the shore.
Tamara Clauson spotted a ruffed grouse camouflaged under trees.
A fox was hunting within 15 feet of a loafing cow moose.
Hosted by AJ DeRosa at his tipi camp before and after his survey, Len Carlman, saw 53 Barrow’s golden-eyes in the Snake River. Len quoted AJ describing the ducks’ behavior vividly: “Teaming up in a riffle, feeding, then seamlessly aligning themselves like a well-made zipper, forming a clean bending mostly single file line as the current moved them to the bottom of the riffle.”
Throughout the region, many reported ravens, magpies, mule deer, elk, and several bald eagles—often in pairs. It is eagle nesting season. The Nortons saw a dipper on Moose Creek.
Small birds, except a few chickadees, were scant, perhaps due to the morning cold.
Other notes:
Two Teton Valley teams noted significant snowmobile tracks into canyons that yielded no moose.
Plentiful moose tracks surrounded exposed haybales indicating indirect feeding—not good for moose.
North of Wilson, a neighbor reported to the surveyors someone feeding moose, “If they want to see wildlife that much, they can look at National Geographic.”
After skiing his survey area on the Snake River Ranch, Ben Wise of WGFD was called to East Jackson where a young moose was bedded down in an open garage. Ben gently nudged it on out. It was likely there for an hour or two.
The contingent from “Hosted Moose Day”, sponsored by the JH Travel and Tourism Board and JH Wildlife Foundation, added their data to Moose Day in an area that was not one of the original survey areas. Twelve years ago, R Park was a gravel pit which prohibited access. It had been left off the maps. Now the park and surrounding cottonwoods are a regular haunt of moose. Thank you Moose Day guests for adding data that count. We will formally include this area in the future.
We had reports from friends and neighbors of moose not spotted by our diligent teams—a reminder that chance plays an important part in seeing moose! Aly Courtemanch said that all reliable sightings within the count time should be recorded, regardless of who saw them. She can then check the data for any duplicates. As in the past, we had several volunteers state they had moose in their backyards or out their windows the day before or after Moose Day. We veterans know: moose disappear on Moose Day.
Thank you!
A moose-size thank you to all Moose Day volunteers for your time, diligence, and indeed perseverance on a frigid morning. Collectively you found and mapped dozens of moose: the goal of the day. Although some of you were understandably disappointed in not finding moose, most all of you reported enjoying the adventure of Moose Day. We are so glad! We also appreciate the engagement of the wildlife agencies. Biologists spent their scant free time to find moose. In addition to those mentioned above, Mark Goecke of WGFD, Morgan Graham of Teton Conservation District; Linda Merigliano of USFS; and Rob Cavallaro of Idaho Fish and Game donated their time. These professionals are dedicated to the wildlife we all love. Thank you. A very special thanks to Aly Courtemanch, biologist with WGFD, who leads this vital partnership with JH Wildlife Foundation’s Nature Mapping program. JHWF Program Director Hilary Turner worked tirelessly on details of the event, especially with the new teams and areas of Teton Valley. Without Aly and Hilary, Moose Day would not happen or matter. Finally, we want to extend our appreciation to the landowners and HOA managers who granted permission for strangers to ski across their properties–slicing tracks into untrammeled snow, and for cars to cruise down private roads, windows cracked with binoculars peering into back-yard bushes. Permission to survey private lands is essential to a successful Moose Day. Final numbers and maps will appear in the next Nature Mapping enews. Thank you all for your time and care.
I truly believe the moose appreciate all you do on their behalf. Frances Moose Day Volunteer Coordinator

We’d like to extend a special thank you to all the new participants and visitors who joined us at Rendezvous Park in sub-zero temperatures on the morning of February, 26th for Hosted Moose Day.
While only one of our hiking groups spotted a moose, it’s important to remember that in terms of scientific data collection, ‘zero’ is still an important number; the absence of moose on the north side of the Snake River levee near Emily Steven’s Park is still a valuable observation to have collected.
A full Moose Day report from all data collected by citizen-scientists in Jackson Hole will be released in the coming weeks.
We hope you enjoy the gallery of images (photos by Jonathan Selkowitz) from this chilly morning spent with frosty fingers, coffee from Pearl Street, and good company!
Citizen scientists, the world round, invest in data collection on the understanding that this effort will contribute to expanding knowledge and the hope that it will move us forward. The timeline for knowledge expansion, and the application of that knowledge, however, can be painfully slow…sometimes long enough that we’ve forgotten about that long-ago data collection. Here, I want to take a moment to tell you about how some citizen science efforts have shaped both knowledge and action to the benefit of wildlife and humans alike near Jackson, Wyoming.
First, who am I that I have something to say about this? My name is Hannah Specht and I work as a wildlife research scientist at the University of Montana. One of the projects I work on is helping with the data analysis from the post-construction monitoring of wildlife collision reduction and movement infrastructure incorporated into the I-89 highway renovation between Jackson and Hoback Junction. Enter, citizen science data that many of you have been involved in collecting! For one, the locations of wildlife underpasses near the WYDOT yard and along Flat Creek were identified as being in areas with higher deer collision rates based on collision hotspot maps produced by Jackson Hole Wildlife Foundation. These maps were based on data from Nature Mapping Jackson Hole as well as WYDOT Crash Data (both of which citizen scientists contribute to). Further, a collaborative initiative supported by volunteers did some pre-construction wildlife camera trapping at the locations where wildlife underpasses were installed, providing us with some baseline knowledge of the animal community. Finally, continued collision reporting has allowed us to compare collision rates before and after the wildlife crossing structures and fencing were installed.
So, what insight have these citizen science efforts offered us? The most important insight is that there were 30% fewer collisions between vehicles and large animals (elk, deer, moose) between Hoback and Jackson in just the first winter (2019-2020) that the underpass and fencing were installed (with the fencing extending only ~30% of the distance). We estimate that this reduction could represent up to $200k in cost savings to the community. We expect that, with additional time to get used to the crossing structures, these numbers will improve even more—we’re eager to update these analyses when the 2021 collision data are available! And, even now that underpasses and fences are installed, there are still problem points that collision reporting helps to identify.
Image: The locations of underpasses and fencing installed by WYDOT along Hwy 89 between Jackson and Hoback Junction Wyoming in 2019. Additional fencing has been installed since then.
In the first year since the wildlife underpasses were completed, we’ve seen a very similar suite of wildlife species using the underpasses as those that were using the area before underpass construction—we’re able to know this because of the camera trapping work conducted before underpass construction by JHWF and other collaborators.
When it comes down to it, growing our knowledge of wildlife and wildlife-human interactions often requires a lot of data across time and covering a large area, frequently beyond the scope of one organization. Citizen science exemplifies what we are capable of, together. Nevertheless, we are all naturally curious about what our collaborative efforts lead to, and in the context of citizen science, we don’t always get to know because sometimes that information doesn’t get used until years later. In other parts of my work, I draw on nature observations submitted to programs like iNaturalist, eBird and eMammal to design wildlife surveys- and it is constantly clear how valuable those data are in making our survey efforts more efficient and effective. So, as a user of citizen science data, I’m here to say thank youfor the ways in which your participation in citizen science helps us learn things in later moments, even if we don’t always know ahead of time when those moments will be.
Did you know that Teton County experiences an average of 71 human-bear conflicts per year? Sadly, in 2021 alone, six grizzly bears were euthanized because of human food-conditioning.
Now more than ever, we believe bears need our help if we are going to continue to coexist compatibly with our wild neighbors.
This is why we are thrilled to announce that over the holidays, JHWF received a generous grant from the Community Foundation of Jackson Hole to help fund a targeted expansion of our Bear Wise Jackson Communication Campaign during 2022.
Bear Wise Jackson is an ongoing partnership with Grand Teton National Park, the Wyoming Game and Fish Department, Bridger-Teton National Forest, and the Jackson Hole Wildlife Foundation.
Research has shown that media coverage and educational materials may be effective in helping to increase regional tolerance for bears.
This broad-reaching educational campaign will be aimed at protecting bears (and people) by providing outreach to residents on how to live safely and compatibly in bear country. It will include materials such as public service announcements, doorhangers, social media, informational brochures and tangible promotional assets.
Examples of assets to be produced include:
A letter to Homeowners Associations placing emphasis on proper bear-resistant garbage storage plus, including a “Who to Call” list in case of emergency problem animal control.
Revised Bear Wise Jackson informational pamphlet via a county-wide mailing.
Management of Facebook and Instagram social media accounts for Bear Wise Jackson content
Doorhangers developed and distributed by volunteers in neighborhoods about compliance with bear safety guidelines.
Spring, summer, and fall public service announcements (PSAs) for airing on local radio stations.
Print ads placed in local newspaper seasonally about the importance of being Bear Wise.
We hope that by raising public awareness we can reduce the number of undesirable human-bears interaction that result in injury or death to both humans and bears, as well as increase public support for both grizzly and black bear conservation.
We’d like to thank you for your commitment to preserving wild bears here in Jackson Hole!
By John Stephenson, Grand Teton National Park wildlife biologist
While people flock to Grand Teton National Park for its spectacular wildlife often hoping for a glimpse of an elusive wolf or grizzly, most visitors are all but guaranteed sightings of remarkable bird species in their travels. Birds are ubiquitous in the park across elevations, seasons, and habitats. Charged with preserving its natural resources, the park relies on partnerships and collaborators to gather invaluable data on the many sensitive bird species in need of conservation. The avian program at Grand Teton National Park operates with the support of other agencies, non-profit organizations, research partners, and a small crew of seasonal staff and volunteers. The birds of the park, like most other wildlife populations, venture beyond the park boundaries, and understanding and protecting these species requires extensive collaboration.
The Biodiversity Research Institute’s permit for Harlequin Ducks research is one of dozens granted for avian studies each year by Grand Teton National Park. Harlequin Ducks winter off the Pacific Coast, but a portion of the population migrates inland to breed each spring in turbulent headwater streams of the Greater Yellowstone region.
At Grand Teton National Park, we are fortunate to have an abundance of bird species and associated long-term datasets for sensitive populations. Notably, greater sage-grouse lek counts date back to the late 1940s and nest productivity data for bald eagles, trumpeter swans, and peregrine falcons were first recorded in the 1980s. For bald eagles and peregrines, annual nest monitoring originated due to their listing under the Endangered Species Act and tracking productivity of these species allows us to follow population trends. Data for other species, such as osprey and great blue herons, help us assess the health of important and often scarce habitats.
In the park, we celebrate the vast amount of protected habitat that is home to stable and healthy bird populations. When the potential for conflict with recreationists exists, the park establishes closures to protect nest sites. We follow seasonal and buffer distance guidelines from the US Fish and Wildlife Service to maintain compliance with the Migratory Bird Treaty Act. Most anglers and boaters are aware of the signed ½-mile no-stopping zones along the Snake River to protect occupied bald eagle nests throughout the summer. Similarly, a popular climbing route in the park has been seasonally closed for years to protect nesting peregrine falcons. In both cases, the public has supported and adhered to these closures which has helped the success of both species.
Resplendent scenery and world-class habitat preserved for mammals and birds alike, makes Grand Teton National Park as must-visit destination for wildlife enthusiasts.
While bald eagle, osprey, and peregrine populations have recovered and are stable within the park, other species are especially vulnerable. For species like greater sage-grouse, trumpeter swans, and common loons, the park participates in cooperative working groups comprised of many stakeholders all with the goal of conserving species on a regional scale across many jurisdictions. These working groups identify threats and causes for population declines and then provide recommendations to address concerns. For example, research has found that sage-grouse in Jackson Hole are limited by available winter habitat, and therefore, the local working group has promoted the preservation of sagebrush habitat and the restoration of the Antelope Flats Hayfields. With input from agency partners and the Wyoming Wetlands Society, regional efforts focus on protecting trumpeter swan nest sites and installing nest rafts to address sensitivity to human disturbance and fluctuating water levels. Common loons have also been helped in recent years by the collective expertise of Biodiversity Research Institute, the Ricketts Conservation Foundation, and our state and federal partners, resulting in the most known territorial pairs in the ecosystem since monitoring began in the late 1980s.
A Greater Sage Grouse takes to the wing against a Wyoming sky. The restoration of native vegetation to the Hayfields at Antelope Flats will ideally provide much needed habitat for this native range-fowl.
Additionally, we issue about a dozen bird-related research permits every year which increase our capacity to understand and ultimately preserve the birds that live in the park. Contributions from researchers working in cooperation with the park have identified migration routes and wintering areas for osprey (Craighead Beringia South), long-billed curlews (Boise State University), harlequin ducks (Biodiversity Research Institute), and rough-legged hawks (Craighead Beringia South and Teton Raptor Center); documented great gray owl and northern goshawk productivity (Teton Raptor Center); discovered a new sharp-tailed grouse lek (University of Wyoming); investigated songbird response to habitat restoration in Antelope Flats (University of Wyoming); surveyed for harlequin duck broods and yellow-billed cuckoos (Teton Conservation District), and documented the nesting ranges of Clark’s nutcracker (Cornell University) and black rosy-finch in the Tetons (University of Wyoming).
Another key project in the park is the Monitoring Avian Productivity and Survivorship (MAPS) bird banding station at the Kelly campus of the Teton Science Schools. This banding site has operated since 1991; is one of the ten longest running MAPS stations in the continent; and has stayed aloft with the generous support of the Teton Science Schools, the Teton Raptor Center, and the Jackson Hole Wildlife Foundation. This site contributes to the understanding of bird population trends throughout their range and has also provided key data locally. Of particular significance was the capture of a yellow-billed cuckoo in July 2000—the only confirmed observation in the park of this federally threatened species.

This banding site has operated since 1991 and is supported by Teton Science Schools, the Teton Raptor Center, and the Jackson Hole Wildlife Foundation.
The birds of Grand Teton have benefited from the interest, expertise, and time of collaborators and partners. Additionally, we value and solicit wildlife observations from the public. Millions of visitors travel through the park every year, drawn by the dramatic scenery and promise of seeing rare or charismatic wildlife. We welcome your reports of common loons, yellow-billed cuckoos, and forest raptors, among many others! From the bald eagle, our national symbol, to the western states’ iconic greater sage-grouse, birds highlight the importance of wild and protected land, the fragility of our natural world, and the power of collaboration.
Growing up in Pennsylvania, I was not intimately familiar with the concept of winter range. Seasonal shifts were marked by hundreds of Canada geese gorging on leftover corn and soybeans. Over time more and more of those migrating geese became yearlong residents, displacing other waterfowl and depositing metric tons of green slipping hazards on sports fields…but that’s a different story. Winter range showed up on my radar in a big way during my first winter in Jackson in 2006. As part of a field technician position, I counted mule deer on winter range from 27 fixed locations around the valley twice a week. Over the following three winters, I listened to a lot of Trash and Treasure, documented 3,230 animals across 417 locations, and developed a greater appreciation for winter range. Monitoring conservation easements, conducting habitat inventories, and 15 seasons exploring public lands have deepened my understanding of why winter range is important.

So, what’s winter range anyway and why should you care about it?
The lack of winter range is widely recognized as one of the most significant limiting factors to mule deer populations. Winter range is the topography, and habitat that mule deer require to survive deep snow, frigid temperatures, predation threats, and human-caused stress. The winter range we see animals using most frequently are the steep south-, east-, and west-facing buttes that receive enough sun and wind to keep snow depths low and natural high-fiber forage accessible, like mountain big sagebrush, Rocky Mountain juniper, antelope bitterbrush, rubber rabbitbrush, Wood’s rose, mountain snowberry, and curlleaf mountain mahogany. It also includes older, closed-canopy stands of Douglas fir and lodgepole pine that shield against heavy snow and cold wind.
When I was a young buck, my body mass could fluctuate by 15% over the year (mule deer bucks can lose 15% of their body mass during the rut alone!). A steady winter diet of beer, pizza, and Netflix transitioning to a summer diet of sunshine, water, and plants would typically put me at my heaviest in April and lightest in October. Mule deer are the opposite. Their fat levels may increase from around 9% in June to 25% in December. They then rely on those fat stores until May when the landscape begins to green up again. If they run out, their body will shift to burning protein/muscle (not good). A dog chasing a deer through deep snow has negative consequences―travel through snow can require 6x more energy than flat ground. What’s harder to reckon are the cumulative impacts of more frequent alertness, standing, and walking in response to humans and pets. Each act of avoidance is a debit on a deer’s fat stores. The best thing you can do is keep your dog under control and observe seasonal wildlife closures. Even if there isn’t snow on the ground, the deer appreciate the space to chill.
So, why we don’t just feed deer the same way we feed elk? There are plenty of biological, social, and behavioral reasons, but the simplest is that it can kill them. Mule deer have evolved to “stomach” our long winters. Deer are heavily reliant on rumen bacteria that adjust seasonally to the foods that are available on the landscape. By the time winter rolls around, a deer’s rumen has acclimated to handle high-fiber, low-protein food. Suddenly dumping high-protein or high-carb fuel like hay or corn in the tank is equivalent to putting gasoline in a diesel engine (also not good). If you want to provide food for wildlife, consider maintaining or restoring some of the native plants listed above in areas away from buildings and roads.
Organizations like Jackson Hole Wildlife Foundation play an invaluable role in amplifying the importance of crucial habitats like mule deer winter range. If you want to help, consider sharing some of the concepts of this post with friends or become a certified Nature Mapper and start logging observations of all sorts of critters on winter and other seasonal ranges.
