As the town of Jackson welcomes the return of yellowing cottonwoods and frosty mornings, we also enter another season of animals on the move. With the chance for large wildlife encounters improving daily, fall’s imminence is an opportunity for us to reflect on how our actions can continue to foster a wildlife-friendly landscape. What better place to start than reminder to be “Bear Wise?”
Bear Wise Wyoming (and Bear Wise Jackson Hole) are collaborative educational campaigns that offer solutions to avoiding human-bear conflict. Both grizzly and black bears enter hyperphagia in the fall, packing on calories in preparation for hibernation. Not only does this mean that bears will be foraging at lower elevations closer to human habitation, but increases the potential for risk-taking behavior in bears, as already opportunistic species morphs into an especially gluttonous eating machines. As human residents of bear country, simple ways we can do our part include:
- Properly storing garbage either in bear-resistant cans or inside a building until morning pickup.
- Storing odorous, recyclable containers indoors.
- Cleaning up unsightly grill detritus and food waste after barbeques and picnics in our yards and amazing public parks.
- Not leaving pet food outside.
- Remember that putting feed out for wildlife violates city ordinance.
- Encouraging our neighbors to do all of the above
Teton County has outlined Bear Conflict Priority Areas for the town of Jackson and strict garbage storage is mandated for certain areas including the West Bank and Cache Creek area. If you are unsure of the Conflict Priority Area where you live, you can access a map on the Teton County website. However, while the probability of a bear encounter might be higher in certain neighborhoods (last year there were 32 verified reports of human-black bear conflict in East Jackson during a two week stretch in October), it is unrealistic to expect bears to limit their fall foraging to politically convenient areas. Furthermore, as grizzlies continue to thrive and expand their ranges to the fringes of this ecosystem, the possibility of grizzly encounters around Jackson remains.
Staying “Bear Wise” this fall mitigates human-bear conflicts and has a byproduct of helping guard against habituation of other smaller scavengers like foxes, ravens and coyotes. Whether it’s a bear or a migrating ungulate that ambles through your neighborhood this shoulder season, we challenge you to be continually intentional in your actions to keep our town creature-friendly, and Jackson a role-model for wildlife-minded communities across the West.
Happy fall wildlife watching!

As the summer comes to an end, we have to say goodbye to our seasonal field staff. This group of amazing individuals helped collect data, led the Monitoring Avian Productivity and Survivorship (MAPS) project, banded Mountain Bluebirds, organized volunteers and produced written and visual content to support our core programs. We hope that in the future we are able to get a group of individuals who are as passionate and dedicated as this crew was. We wish them the best as they move forward in their promising careers.

Here’s a bit about where each is going next:
Lead Bird Bander Kate Maley (top left) is headed to the Midwest to band owls at Hawk Ridge Bird Observatory in Duluth, Minnesota. This long-term research station primarily looks at Northern Saw-whet Owls in hopes of learning about migration and population demographics.
Assistant Bird Bander Max Frankenberry (top right) is headed to Casper, Wyoming to help conduct eagle surveys at wind energy sites, in hopes of lowering mortality rates while promoting compatibility between new energy technology and wildlife. Max will also be helping conduct a bumblebee study with the USGS.
Summer Intern Victoria Hollingsworth (lower right) is headed over the hill to live in Victor, Idaho in hopes of pursuing a job in outdoor and art education. She is looking forward to meeting new people and continuing her passions.
Summer Intern Tyler McIntosh’s (lower left) next stop is the big island of Hawaii, where he will help organize and teach an environmental field science program for undergraduate students. He is excited about the opportunity to continue developing his skills as an educator and passing along his passion for the natural world. He also won’t complain about exploring the Hawaiian reefs and beaches! In the future, Tyler hopes to work on conservation and management issues with non-profits and government agencies in the American West. He seeks to integrate community-engaged decision making with conservation research while providing meaningful educational opportunities.

After nine weeks of banding birds this summer, JHWF’s first MAPS season has officially come to an end. Every Wednesday and Friday sunrise, from June 6th to August 3rd, was spent setting up nets, collecting data on the birds we caught, and attaching small aluminum USGS-issued bands to their legs. All in all, this season produced 677 total bird captures, with 453 new birds banded this season.
Bird banding is a highly-effective research method used worldwide for tracking bird movement, survival rates, and reproduction success. Banders are trained in specialized bird handling, safety, and data collection, and can only legally band birds if covered under state and federal permits. Each band number is unique to each individual bird. Banders report both new bands placed on previously unbanned birds, and bands that are on birds that they recapture after already being banded before. Other data like age, sex, weight, and various conditions are also collected and reported, forming the massive database of information that USGS and various ornithological groups manage and analyze.

MAPS stands for Monitoring Avian Productivity and Survivorship. It is a specific banding program begun by the Institute for Bird Populations (IBP), with a goal of better understanding survival rate and nesting success while birds are at their summer breeding grounds. JHWF bands birds following IBP protocol — opening nets at sunrise and closing them six hours later — and submits data to the IBP database. This builds on the years of previous data collected on birds in Jackson Hole from Teton Science Schools (TSS) and Teton Raptor Center (TRC), who helped transition the program to us this year. Our two banding locations, Teton Science Schools’ Kelly campus and Boyle’s Hill on their Jackson campus, have been contributing data without a break in observations for 28 and 16 years respectively. Kelly is one of the longest operating MAPS stations in the country! Long-term, uninterrupted data sets are crucial to understanding trends in bird population shifts. Thanks again to TSS and TRC for making the transitions between organizations so smooth!
The 2018 season ended with 180 recaptures (out of 677 total captures) of previously banded birds, with several of these birds having been banded even before the 2017 season. Much like years before and not surprising to those of us that live in Jackson Hole, our most popular species caught were Yellow Warblers and American Robins (AMROs). In total, 109 new Yellow Warblers (or YEWAs in banding code) had bands placed on their legs this year, many of them young birds born this summer. YEWAs are doing just fine in our valley! American Robins were our second most common bird this year, with 57 new birds banded. While we had constant flows of incoming YEWAs and AMROs, we also had a few particularly exciting individuals as well. By far the most unexpected were a pair of Belted Kingfishers, each caught a week apart from each other! While kingfishers are not uncommon here, they are rarely caught in banding stations, mostly due to their preference for flying much higher than the nets and perching on trees overhanging water.

Belted Kingfishers have detailed white patterns on their flight feathers – we can use these to figure out how old the birds are!
We were excited to say the least. Other species that graced us with their surprising presence were a very vocal Olive-sided Flycatcher and a juvenile Brown Creeper. We also had 40 birds that were captured and released but not banded, including large number of Rufous, Calliope and Broad-tailed Hummingbirds (our banding permit does not allow hummingbird banding – that requires additional specialized training). Overall we captured 45 different species of birds over 9 weeks. This guaranteed that we never had a slow morning at either banding station!
Other wildlife sightings always kept us on our toes throughout the season – early mornings at Kelly and Boyle’s Hill allowed us views of several moose and calves, foxes, a grizzly bear, a family of otters, and even an elusive mountain lion! Sunrise work with birds in the Greater Yellowstone Ecosystem meant bear spray and our favorite badly-sung show tunes had to always be at the ready.

We want to thank all who have made this program possible. This effort to track birds in our valley really does contribute extremely valuable data to a great continent-wide program. The MAPS data has resulted in many highly regarded publications on the state of bird populations in North America and new ways to manage and preserve them. Thanks for being “for the birds”!

GUEST BLOG: The Jackson Hole Wildlife Foundation asked our friends and fellow Nature Mappers, Betty and Chuck Mulcahy to share a bit with us about their current volunteer work at the National Elk Refuge. Betty and Chuck do a lot to educate the public about the wonders of snakes and demystify their wicked reputation. Don’t be afraid, read on and learn about our serpent friends:
“Count the snakes and keep your distance!” a friend warned in an email after we told her our new assignment for biological work on the National Elk Refuge was to survey reptiles, mainly counting the snakes.
Unknown to her, the snakes in Jackson Hole are comprised of three non-venomous species. Because one species, the rubber boa, is nocturnal, we don’t expect to encounter it on our rounds, although our biologist mentioned he had seen one once during the day.
The other two species are the wandering gartersnake and the valley gartersnake. The wandering gartersnake is the more numerous and is unlikely to bite if picked up. Instead, this species prefers to defend itself by exuding a musk in your hand, much like pooping. As we tell school children when we present a reptile program in their classrooms, this defense is very effective due to the pungent odor! Their response is always the same: “Eeeeeew!”
However, locating snakes on 25,000 acres can be tricky – perhaps likened to searching for the proverbial needle in a haystack. Our long-time mentor in snake locating is a Denver Zoo reptile keeper, as well as rattlesnake researcher, who can find a snake with the ease of a professional.
In the past, we have spotted snakes on top of Miller Butte, thermoregulating across roads, swimming in creeks, and hiding in sidewalk cracks and under steps. Now, scouring the Refuge, we flip rocks, turn logs, lift tarps, and trudge through thick vegetation in our search.
Because snakes have yet to be surveyed on the Refuge, no precedent is set for their documentation. Consequently, we outline our search area on a map and record date and findings in a comment section. Finding nothing is as important to record as our successes, according to our biologist, as is recording any dead serpents.
While the wandering gartersnake can often be found at a distance from water, the valley gartersnake is found more often near water and is believed to have declined in population over the years.
We hope to encounter each of these species!

To keep up-to-date on Betty and Chuck’s survey and other adventures you can follow along via their blog Have Snakes Will Travel: The Unconventional Lives of Volunteer Naturalists.
For more detailed information including photographs on the three snake species found in Teton County, WY visit the following links:
- Northern Rubber Boa – Charina bottae – looks like a fake rubber snake, with its lack of distinctive head or tail or any markings. In Wyoming, it is found only in the mountainous northwestern region.
- Wandering Gartersnake – Thamnophis elegans vagrans – is by far the most common gartersnake in Teton County and ranges across the state. The body background color varies from brown to olive, and the stripes and markings can vary in intensity, but it will not have red.
- The Valley Gartersnake – Thamnophis elegans fitchi – has a very limited range in Wyoming: the very western edge of Teton and Lincoln Counties. It is distinctive from the Wandering Gartersnake by its red accents.

Since Chuck Schneebeck started the Bluebird Trail in 2003, members of the Jackson community have endeavored to create nesting habitat for Mountain Bluebirds and other native cavity-nesters along the southwestern edge of the National Elk Refuge. After many years of observation and data collection, at least one thing is clear: the birds are definitely using the nestboxes! But what effect are the boxes having on the population?
![](https://jhwildlife.org/wp-content/uploads/2018/08/2018-06-14_14-54-59_545-1-e1535141235249-768x1024.jpeg)
While we focus on Mountain Bluebirds, we are equally pleased to see other native cavity nesters using the nestboxes! Tree Swallows are the most abundant nesters along the Bluebird Trail, though they arrive after most bluebirds have settled into their territories for the season.
Jackson Update:
In 2017, JHWF began expanding upon the existing data and investigating new questions when our previous bander Allison Swan and monitoring volunteers started placing USGS aluminum bands and a unique series of color bands on Mountain Bluebird nestlings and one adult female. These color bands, or “bling,” allow us to identify each individual bird as it disperses from its nest and, hopefully, returns to a similar area the following year to raise some little bluebirds of its own!
Still in the early stages of the banding project, we don’t have many definitive answers yet, but we are learning lots! Of the 98 bluebird nestlings that were banded in 2017, only a handful have been resighted this year. This isn’t as surprising as it may initially sound, however. The first year of a bird’s life is the hardest as they learn to fend for themselves and navigate migration. Optimistically, we estimate that around 50% or fewer birds make it back to their breeding grounds in their second year. Once back in Jackson Hole, they disperse from their original nest site to independently begin a family of their own. Where do they go? That’s one of the things we’re hoping to discover!
![](https://jhwildlife.org/wp-content/uploads/2018/08/Max-768x1024.jpeg)
Max Frankenberry, Assistant Bander, secures the color bands on a nestling to help ensure they will stay on and be able to be spotted next year.
While migration is still a taxing journey for adult bluebirds, they do benefit from experience. In addition, adult bluebirds tend to have higher site fidelity, meaning they are more likely to return to the same site to breed for multiple years. So far, the one banded adult mountain bluebird did, in fact, return to the exact same nestbox where she was banded in 2017!
Admittedly, 2018 was a tough year for nestbox inhabitants as almost half of the nestboxes were within a stretch affected by predation events. (Exact numbers are still being determined as we close out the season and compile the data.) In response, we placed a number of predator guards that are recommended by the North American Bluebird Society. Fortunately, most of the guards did seem to effectively prevent the depredation of a second nesting attempt. Even with the challenge of a predator, nearly all of the 112 available nestboxes were occupied by native cavity nesters (Mountain Bluebirds, Tree Swallows and House Wrens). Of the Mountain Bluebird nests, about 75% successfully fledged young. In total, 72 nestlings were banded in 13 nestboxes (some had two broods throughout the season).
Now, we’ve reached the point in the season when bluebirds of all ages disperse from their nest sites and seem to gather into groups by age to take advantage of the last of summer’s bounty and fatten up before migration. So, if you keep an eye out for “Bluebirds with Bling,” you’re likely to see some from the 2018 cohort (indicated by a peach color band on the bird’s right leg, closest to the body) and possibly some from 2017 as they group up prior to beginning journey south.

Meet one of the members of 2018’s cohort of bluebirds! The location of the peach color band (top right) will allow us to easily identify it as having hatched and been banded this year. Left: Black over Green, Right: Peach over Silver
Dubois Update:
Last year was also the first year of the Dubois Community Bluebird Trail. The project continued in 2018 with 35 nestboxes monitored by 9 volunteers. We’re still waiting to finalize the data prior to analyzing the results from the season, but we’re looking forward to what we find out!
Thank you to all our hardworking volunteers and partners in both Jackson and Dubois who make this project possible!

Nancy and Blair Butterfield were kind enough to give us an update and tour of their nestboxes when we visited Dubois in July.
