Individuals Matter Too! – When You Can ID Them
The following piece was written by OAS Communications Coordinator Ryan Bower for the Snapshot Wisconsin newsletter. To subscribe to the newsletter, visit this link.
Elk are similar to deer in that they lack identifiable markings most of the time. This makes it hard to know whether an elk in one photo is the same elk that appears in another photo. However, some elk in Wisconsin have uniquely numbered collars, making it possible to identify one individual elk from another.
Using these collars, researchers can piece together all the Snapshot photos of that elk and follow its movement through time. Knowing that the elk in two different photos is the same individual holds a special type of power for researchers and tells them extra information about the size of the elk herd. That is, if the researchers can leverage that additional information.
Glenn Stauffer, Natural Resources Research Scientist within the Office of Applied Science, is leading the initiative to identify individual elk and use these data to improve the annual elk population estimate. Stauffer said, “I was approached because of my quantitative modeling experience to evaluate different ways of using the elk photographs as data to fit an elk model. [Collectively,] the various models I and others have worked on provide a range of options to estimate the [elk] population size and to evaluate how reliable the models are.”
Identifying Individuals
To better understand the significance of Stauffer’s work, it helps to know how elk have historically been counted in Wisconsin.
“Long before I came onto the scene, the primary way of counting elk was to go out and count them all,” said Stauffer. This method requires extensive time in the field and considerable local knowledge about where elk groups often hang out. Researchers could count some elk by their numbered collars, but they also needed to know how many uncollared elk were in each group. The elk herd grew over the years, and more and more elk did not have identifiable collars. This added another challenge for researchers who were trying to count all the unmarked elk (and make sure they weren’t double counting any of them).
Since the estimate of the elk population size still needed to include an unknown number of these unmarked individuals, the DNR started experimenting with models that didn’t require individual identifications. These new models were also a boon because the herd was reaching too large a size to efficiently collar. It was becoming too much of a time investment and was expensive.
Instead, these models are based on images from the Snapshot camera grid, as discussed in the previous article, but even these camera-based models had room for improvement. Thus, Stauffer began researching a model that incorporated the best of both approaches: a model that was based on the camera data but still incorporated limited individual identification back into the model.
Stauffer’s Model
Stauffer looked into a variety of models but zeroed in on one type of model in particular. Stauffer explained that this model belongs to a class of models called spatial mark resight models. Spatial mark resight models combine the best of both marked and unmarked models. Stauffer’s model identifies individuals by their collars but also makes inferences from the photos of unmarked elk at the same time.
Spatial mark resight models also relax a major assumption made by the previous camera model, the closure assumption. “This assumption states that the number of elk at a particular camera location doesn’t change from one encounter occasion to the next, and it is clearly violated. Elk are wandering from camera to camera,” said Stauffer. Stauffer’s hybrid model relaxes the closure assumption and attempts to figure out the minimum number of distinct elk it can identify from the pictures.
Collared elk are often easy to identify in the photos. These collared elk are given the ID assigned to their respective collar number so that all photos of a particular elk share the same ID. The model also attempts to assign IDs to uncollared elk in the photos. The model uses probabilistics to assigns IDs to all remaining elk – either uncollared elk or unknown elk (because the collar or the collar number isn’t visible in the photo) – based on characteristics visible in each photo.
Fortunately, Stauffer’s model uses as much information as it can get from the photos when assigning IDs. For example, if one photo is of a calf and another photo is of a cow, then the model won’t assign the same ID to these animals. After all, we know those are two distinct elk, not one. Similarly, a marked but unidentified elk with one collar type can’t be the same as another unidentified elk with a different collar type. The model even uses spatial data to differentiate unmarked elk from two different photos. For example, photos at two locations close together might be from the same elk, but photos from two distant locations probably represent two different elk.
Capitalizing on all the information available in the Snapshot photos, the model makes an estimate of how many elk are likely in Wisconsin’s elk herds. As the elk herds continue to grow, this modeling approach helps estimate the elk population and hopefully saves the DNR time and money.
How well does the model work?
“[Technically,] the spatial count model doesn’t require any information about individual IDs, but it performs pretty poorly without them,” said Stauffer. “There is a series of papers from about 2013 on that shows if you add information about individuals to spatial counts, you can really improve the accuracy and precision of the spatial model.”
“Theoretically, this makes the model estimates more precise,” said Stauffer. To check, Stauffer collaborated with a colleague to run a bunch of simulations with known, perfect data, and the model worked reasonably well. These simulation results are encouraging because the model wasn’t massively overpredicting or underpredicting the number of elk in the herds, both of which could have management implications for elk.
When asked if identifying individuals from photographs is worth the extra effort, Stauffer said, “Working with models that don’t require individual IDs still requires considerable time to classify photos. Identifying individuals is only a little bit more work on top of that. In general, when you can’t meet the assumptions of a model, then it is worth getting individual identifications, if you can.”
Just how much additional effort should be put into individual IDs? Stauffer believes part of the answer comes from asking what other information can be obtained from the collars. “If we are already putting the collars on those we capture or release, then we might as well get as much out of them as possible, such as through using photographs [like Snapshot does],” said Stauffer.
Incorporating Another Year
After the Snapshot team finishes assembling the 2020 elk dataset, a large dataset comprised of the data from all the Snapshot photos of elk in 2020, Stauffer will run his model using this new dataset and generate an estimate of last year’s final elk population. Stauffer’s estimate will be closely compared to other estimates generated by the previous camera-based models and through collaring efforts alone to see how well each approach performs.
Stauffer took a minute to reflect on his work so far with the elk population estimate. Stauffer said, “The modeling process has been really rewarding, diving into this topic in a depth that I would not have done if I did not have this Snapshot photo dataset to work with. The simulation also went well. It illustrated that the model works the way we claim it works, which is good. Fitting the model to the elk data is mostly encouraging, but it shows that there are situations where it doesn’t do as good of a job as we hoped. Specifically, for calves, it still needs to be fine-tuned.”
From physically counting elk to modeling counts of only unknown individuals to modeling counts of both unknown and known individuals, Wisconsin’s approach to estimating elk abundance has evolved through time. Chances are, as the composition and distribution of the herd changes in the coming years, the approach will evolve even more. But for the next few years, Stauffer’s work will help direct how we count elk now.
Elk Snapshots Mean Better Elk Modeling
The following piece was written by OAS Communications Coordinator Ryan Bower for the Snapshot Wisconsin newsletter. To subscribe to the newsletter, visit this link.
At the start of every year, DNR staff begin compiling a large dataset of elk sightings from the previous calendar year, and the data, once compiled, is used to calculate the total number of elk that live in the state. This method has been a standard practice since the second reintroduction of elk to Wisconsin.
What some of you may not know is that Snapshot plays an important role in counting elk by providing sightings, particularly of bulls. In fact, Snapshot has more than 250 of its cameras (over 10% of all Snapshot cameras) dedicated to monitoring elk alone. These cameras are clustered in the three areas of the state with part of the elk herd – Clam Lake, Flambeau River and Black River Falls. These elk cameras are arranged into a grid-like pattern in each area, just like the rest of the Snapshot grid, except that the density of cameras in the elk grid is a lot higher.
A few members of the Snapshot team are among those working on the 2020 elk dataset, so the team decided to focus this newsletter on elk and how they use photos to learn about the elk herd.
The Snapshot team invited Dr. Jennifer Price Tack, Large Carnivore and Elk Research Scientist and fellow scientist within the Office of Applied Science, to add her perspective to this newsletter on why Snapshot’s photos matter for elk.
The task of integrating Snapshot data into the elk model was originally the work of Joe Dittrich, who laid a solid foundation for Price Tack. Since Price Tack joined the Office of Applied Science at the end of 2019, she has been using Snapshot data to model how various quota alternatives will affect the elk herd size in the years to come.
“My research focuses on [elk] populations because populations are the scale at which we manage wildlife,” said Price Tack. Population is the starting point for all decisions that are made about managing wildlife in Wisconsin. The status of a population determines how decisions are made, policy is framed, quotas are set, permits are allocated, and so on… Population is the unit of concern for the DNR.
Price Tack continued, “While individual animals are important and make up a population, our ability to manage them breaks down some at the individual level, [simply] due to the infeasibility of monitoring individuals.”
For species like elk, which normally lack easy-to-identify markings, individual identification is often difficult. Possible, as discussed in the next article, but difficult. Thus, populations tend to be the scale of most species work at the DNR, including Price Tack’s work on elk.
As Price Tack walks us through her research on the elk population, check out the unique way that Snapshot photo data are used to monitor this large herbivore population.
Feeding Photo Data Into The Model
Photos of elk can have multiple forms of data in them, beyond just what animals are present in the picture. There is camera location data, for example, which provides information about which areas of land the elk are using and not using.
There is also movement data. The Snapshot team learned that elk calves, cows and bulls have different movement patterns and are seen at different rates throughout the year. When bulls are the most active, for example, cows tend to be less active.
The camera data also helps Snapshot determine a calf-to-cow ratio for elk. Although, it isn’t as simple as dividing all the calf photos by the number of cow photos. Cows move around more than calves do and are more detectable in photos, given their larger size. Using knowledge about calf/cow visibility, calves and cows are modeled separately, and those numbers are then used to calculate the calf-cow ratio for elk.
“I remember first learning about Snapshot and thinking it is such a cool resource! There is so much you can do with camera data.” said Price Tack. “I have experience working in other systems that use camera data, so I know [firsthand] that using camera data has a lot of benefits” – benefits like providing many forms of data at once and being more cost-effective than extensive collaring. “I wanted to tap in and work with these folks.”
Price Tack mentioned that she even had the Snapshot logo in her interview presentation. She was already thinking about how to get the most out of Snapshot’s camera data.
“Now that I’m here, my focus is on filling research needs to inform decisions,” Price Tack continued. “[Our research] is going to be critical to helping wildlife management and species committees make informed decisions for elk, such as deciding elk harvest quotas in the upcoming years. Snapshot data is one tool we can use to fill those research needs. It is available, and I’d like to use it as much as feasible.”
Besides estimating the population of the elk classes (e.g. calves, cows and bulls), Snapshot data is currently being used to help estimate population parameters and help us understand what is happening with the population. Population parameters are estimates of important characteristics of the population, such as recruitment (birth rate), mortality (death rate) and survival rates of different elk classes within the population.
Price Tack’s model uses matrix algebra to take an initial elk population size and projects the population into the future, using what we know about elk population parameters. In other words, the model can predict how large the elk population is likely to grow in the years to come. There is natural variation however, that can cause some years to be unpredictably good or bad for elk, so the model needs to be updated each year to keep its accuracy as high as possible.
Thanks to Snapshot’s camera data, we have a system in place to calculate each year’s population parameters and continue updating the model each year. This should help us catch if anything of concern happens to the population and (hopefully) fix it before it becomes a threat.
Improving the Elk Model
Another of Price Tack’s tasks related to Snapshot is improving the elk model. Many of the improvements Price Tack is researching aim to address data collection for a larger population.
The elk population was very small when the DNR first reintroduced elk to the state in 1995 and again in 2015. The DNR used intensive monitoring methods back then to collar (and track) every elk in the herd, since intensive methods are best suited for small populations. However,with the elk herd doing so well, it won’t be long before a different approach is needed. The DNR wants to transition to a method more appropriate for a larger elk population.
Currently, the DNR is early in the process of ramping up non-invasive, cost-effective methods like Snapshot monitoring and toning down the collaring effort. Although, this transition will take time, happening over the next few years.
Price Tack also mentioned another modification under consideration. Price Tack and the Snapshot team are looking into repositioning some of the cameras within the elk grid. Currently, the elk grid doesn’t perfectly align with where the elk are congregating. There are a few cameras outside of the elk range that don’t see any elk, and there are edges of the elk’s range that extend beyond where the cameras are deployed. Repositioning the cameras should mean more elk pictures, which means more elk data.
The Frontier of Camera Monitoring
The role of Snapshot in monitoring elk is evolving, and Price Tack and the Snapshot team believe it is for the better. While they can’t guarantee that Snapshot will always play a central role in collecting data on elk, Snapshot will fill this role for the next few years at least.
Price Tack said, “This is the frontier of using camera trap data for elk. Every year, new approaches to using camera trap data are being developed. That has me excited that, even though we don’t have all the answers now, more opportunities may be on the horizon.”

Virtual Bald Eagle Watching Days 2021
Bald Eagle Watching Days has been an established community event in Sauk Prairie, Wisconsin since 1987. Bald eagles can often be found near rivers that provide ample fish, and the Wisconsin River that runs through Sauk Prairie has made this a perfect location for eagle watching.
With public health and safety a main concern, the annual Bald Eagle Watching Days have been moved online this year. The events will be live-streamed for everyone to watch from the comfort of their own homes and can be accessed by clicking here.
Events will take place on Jan. 16th and 23rd as well as Feb. 6th and 20th. As is custom, Bald Eagle Watching Days is kicking off with a live release of rehabilitated bald eagles!
Other exciting events include presentations on eagles in Native American culture, the wintering ecology of eagles in the lower Wisconsin riverway, bald eagle behavior, a bird of prey show, and many more!
In 2019, I was able to attend Bald Eagle Watching Days in person. Hundreds of people crowded together in a park along the Wisconsin River to witness the release of a few rehabilitated bald eagles. It was a frigid January day, and I remember questioning whether standing out there was worth it. However, as the wildlife rehabilitators began to prepare the eagles for release, I decided it was definitely worth it. As far away as I was, I remember being awe-struck by how large they were. The rehabilitators told us the story of how the eagles had come into their care, and then with a huge woosh, one by one they soared into the air. A hush fell across everyone at the park as we were all overcome by strong emotions. Viewing these magnificent raptors online may not be exactly the same experience as seeing them in person, but I have no doubt that their majesty and power will be conveyed just the same. Help send them off with your support and well-wishes by tuning in on January 16th!
Partnering with the Natural Resources Foundation and a New Snapshot Store!
The following piece was written by OAS Communications Coordinator Ryan Bower for the Snapshot Wisconsin newsletter. To subscribe to the newsletter, visit this link.
Some of our volunteers may already know that Snapshot Wisconsin recently partnered with the Natural Resources Foundation of Wisconsin (NRF), but we at Snapshot haven’t shared many of the details about this partnership yet, including new opportunities available to volunteers and a Snapshot merchandise store!
Christine Anhalt-Depies, Project Coordinator for Snapshot Wisconsin, virtually sat down with Cait Williamson, Director of Conservation Programs within the NRF, to chat about what this partnership means to their programs, as well as highlight how their volunteers benefit from this partnership.
What is the Natural Resources Foundation of Wisconsin?
The NRF is a non-profit foundation that is all about funding conservation work. The NRF has a long history of supporting the DNR’s priority projects, especially those that involve species with the greatest conservation need. The NRF also connects people to conservation opportunities throughout the state through their Field Trip program, the Great Wisconsin Birdathon and many other funded programs.
The NRF was established in 1986 after significant cuts to the DNR budget. The DNR leadership at the time recognized a need to have an independent foundation to bridge private sector support for natural resources and conservation work being done, so the NRF grew to fill that need.
Williamson added, “We support over 200 different projects each year from small-scale school projects to large-scale conservation projects, even [projects] at the federal level. Our niche is conservation funding, leveraging resources from corporations, foundations and individuals. Putting those financial resources to the highest priority conservation needs for Wisconsin.”
Snapshot Wisconsin fits well into the types of projects that the NRF funds, so this partnership was a natural fit. Plus, forming this partnership had a special twist in store for Anhalt-Depies and Williamson.
Forming this Partnership
Anhalt-Depies and Williamson first sat down over coffee over a year ago to discuss forming this partnership. However, the meeting was more than just a brainstorming session about what the partnership would look like. It was a reunion for Anhalt-Depies and Williamson.
The pair first met while Anhalt-Depies was working on her project for her master’s degree nearly a decade ago. Part of the project involved radio-collaring wolves, so Anhalt-Depies collaborated with the DNR. Meanwhile, Williamson was an intern with the DNR, assigned to work with the wolf program. Anhalt-Depies and Williamson worked together very closely for months until the field work was done, then they went their separate ways.
Anhalt-Depies later went on to work with Snapshot Wisconsin and eventually became the project coordinator. On the other hand, Williamson started working at the NRF and became the one who builds partnerships with the DNR (and other conservation or education groups), as well as determines what the NRF’s priorities are. Williamson said, “I have the fun job of giving away the funds we help raise and knowing those are going to have the most impact they can.”
Anhalt-Depies explained what motivated her to reach out to Williamson again. “As Snapshot grew to a state-wide program, we identified the need to partner with groups that could help us expand our reach, especially in the area of supporting education. NRF seems like a natural fit, based on their goals and mission. I reached out to [Williamson]. We sat down and had a great brainstorming session about what a partnership between the two would look like and how we could help each other reach our goals.”
Williamson added, “It was fun to reconnect with [Anhalt-Depies]. We [at the NRF] have heard about and been informally in-the-loop on Snapshot Wisconsin, so it seemed like a natural fit because of what Snapshot is – engaging people and providing critical data. It was a no brainer for us.”
“It’s awesome to be able to offer yet another opportunity for our members and our partners to engage with Wisconsin’s natural resources,” said Williamson, and engage, they can. Not only do Snapshot volunteers benefit, but so do the NRF’s members.
How do Snapshot Volunteers and NRF’s Members Benefit?
Anhalt-Depies shared how this partnership benefits Snapshot volunteers. “This partnership helps expand our reach,” said Anhalt-Depies. “It brings the Snapshot program to a new audience, helping us to continue to grow.”
Anhalt-Depies continued, “The fundraising support NRF brings to the partnership will also help to increase our educational impact. Roughly 15% of Snapshot volunteers are educators. This partnership will expand the resources available to these educators, helping them to better integrate conservation education into their classroom.”
At the same time, the NRF and its members benefit from connecting to Snapshot Wisconsin. Williamson said, “From a conservation side, we [the NRF] are all about supporting priority needs for our state. Science-based conservation and the data that informs it is super critical, so we are happy to be able to support Snapshot and growing the program.”
“For our members, Snapshot Wisconsin is a really good way to connect them with something they can do,” continued Williamson. “Whether they are hosting cameras or classifying images on Zooniverse, it gives them one more way that they can give back to Wisconsin’s natural resources.”
A Message From Our NRF Partners
Another important way that the NRF is helping Snapshot Wisconsin is through providing funding opportunities, either through donations or merchandise sales. Our partners shared with us a special message for Snapshot volunteers, announcing these new ways to help out the Snapshot program.
At the Natural Resources Foundation of Wisconsin, we believe that nature has inherent value and that people have the ability to make a difference. We are the bridge connecting people who want to help with meaningful opportunities to make a lasting impact on Wisconsin’s lands, waters, wildlife and future stewards. We are very excited about our new partnership with Snapshot Wisconsin, which will connect our NRF members with meaningful volunteer opportunities, directly fund efforts that inform conservation decisions and help us learn more about Wisconsin’s amazing wildlife.
Want to show off your love for Snapshot Wisconsin and help support this incredible program? Check out our Snapshot Wisconsin storefront, featuring t-shirts, sweatshirts, hats and mugs – every purchase directly supports Snapshot! You can also donate directly by visiting
WisConservation.org/donate and designating your gift to Snapshot Wisconsin.
Between connecting our volunteers to the resources of the NRF network and new funding to expand what Snapshot is able to do, the Snapshot team is excited for this partnership. There is so much synergy between Snapshot’s goals and NRF’s mission that this partnership is a natural fit.
The partnership has also brought back together Anhalt-Depies and Williamson, and each shared some parting words for readers.
Williamson said, “Five years back, we had a visioning session about what we were really accomplishing for conservation in the state. We are not the boots on the ground ourselves, but what we do is connect people to that. There are so many ways people can make a difference. Whether it is through philanthropy, volunteering their time or just the personal choices they make to support our state’s natural resources… We are all about how people can make a difference, and Snapshot is one of those ways.”
Anhalt-Depies added, “Snapshot is people-powered research. We have thousands of volunteers who are donating their time and making a huge impact on the number of photos collected and total information gathered on our state’s natural resources. This partnership with the NRF helps to make their efforts go just a bit further, and at the end of the day, that is what matters.”
The Snapshot Team’s Favorite Photos from the First 50 Million!
The following piece was written by OAS Communications Coordinator Ryan Bower for the Snapshot Wisconsin newsletter. To subscribe to the newsletter, visit this link.
Snapshot Wisconsin recently reached an important milestone: its 50 millionth photo! We’ve been watching the tally of photos get closer and closer to 50 million for the last few months, and we are thrilled that the moment is finally here.
Snapshot Wisconsin started as a pilot program in only two counties in 2016 but expanded statewide in 2018. Today, we have over 1,800 volunteers, monitoring over 2,100 trail cameras across the state. Furthermore, the Snapshot program receives approximately 45,000 photos per day from all these cameras. Just stop and think about how incredible that is!
As a thank you to everyone who has helped the program out or followed its success (and to celebrate the 50 millionth photo milestone), the Snapshot Wisconsin team selected some of their favorite photos from the first 50 million and used them to build an interactive map of Wisconsin. This tool highlights each photo and tells a short story about the photo itself or the species shown. It serves as a “snapshot” of how the program has grown over the years.
Rare species sightings, unusual animal behaviors, species facts, and even a few multi-species encounters can all be seen in the interactive map. Check it out!

The Cultural History of Turkeys in America

Turkey from Iowa County captured on a Snapshot Wisconsin camera.
Thanksgiving arrives next week, and the iconic image that pops into most people’s minds during this holiday is a big, roasted turkey in the middle of the kitchen table. But how did these large birds become a classic representation of this holiday? We took some time to dive a little deeper and learn more about the history of turkeys in North America, how Thanksgiving became a holiday, and how turkeys ended up as the main attraction on this day.
Wild turkeys (Meleagris gallopavo) have always been native to the Americas. In fact, there is only one other species of turkey in the entire world: the Ocellated Turkey (Meleagris ocellata), which lives in Central America, and has beautiful plumage that more closely resembles a peacock than the wild turkeys we are familiar with.
Importance in Native American Culture
Before their popularity in modern Thanksgiving feasts, turkeys have been an important part of the food and cultural systems of Native Americans for thousands of years. There is archaeological evidence of wild turkeys being domesticated by certain indigenous groups as far back as 2,000 years ago. Not all native communities domesticated the birds since they were so abundant, but tribes in the American southeast, southwest, central Mexico, and Guatemala were especially known for their domestication of turkeys.
Beyond serving as a source of food, the rest of the turkey’s feathers and bones were used for tools, regalia, and art. The reverence of turkeys varied widely from tribe to tribe and has a complex and beautiful history in native culture. The Wampanoag tribe in the east used turkey feathers for cloaks, while the Tuscarora and Catawba in the south used plumage for headdresses. In other tribes, turkeys played a role in traditional stories. The Caddo have a prestigious Turkey Dance related to tribal songs of war, honor and pride. Even through generations of genocide, forced removal from their lands, and substantial portions of culture that have been lost forever, turkeys still carry importance in the lives and ceremonies of many tribes today.

Introduction of Turkeys to Europeans
Turkeys made their debut in European and Asian cuisine in the 1500s through Spanish trade routes. Many suspect that they received their name because these birds came to Europe by way of the country of Turkey. They were so popular with Europeans that the colonists even brought domesticated turkeys with them as they sailed to North America. To the colonists’ surprise, the large birds were already fairly abundant here.

The Founding of Thanksgiving
Despite popular legend, wild turkey was not served at the 1621 meal shared between the Wampanoag natives and the pilgrims. Instead, deer meat was provided by Wampanoag hunters.
The pilgrims had many seasonal “days of thanks” for a good fall harvest, and continued this tradition when they moved to North America, however there was not originally one common day that this was celebrated on.
In the mid-1800s, writer Sarah Josepha Hale campaigned to make a single national holiday out of these common thanksgiving celebrations. Her goal was to bring the country together at a time when the Civil War was eminent. In 1863, Lincoln officially declared Thanksgiving as a U.S. national holiday.

How Turkeys Became a Thanksgiving Icon
Turkeys became the meat of choice for Thanksgiving celebrations because they were easy to harvest and their size was enough to feed a large family. Many families even had domesticated turkeys that they raised on their farms specifically for the purpose of a holiday meal.
Unfortunately, their popularity soon became their downfall as wild turkeys were overharvested throughout the 1800s. Soon, they were no longer found in most states. The last turkey disappeared from Wisconsin in 1881.

Wildlife Success Story
Fortunately, nationwide efforts to revive turkey populations have been largely successful. In Wisconsin, wild turkeys were reintroduced by the Department of Natural Resources in 1976. Twenty-nine wild turkeys imported from Missouri were released in Vernon County. As they began to flourish, the new turkeys were trapped and relocated to other counties across the state. Now, tens of thousands of wild turkeys are harvested every year in Wisconsin. Click here for more details about hunting turkey in Wisconsin.
Whether you enjoy them for their meat, their beautiful plumage, or the fierce confidence they embody as they strut across the road, take a moment to give thanks that these magnificent birds are still around today!

Rare Species Update: Moose Sightings
Moose are considered a rare species in the state of Wisconsin. They used to be found across the northern part of the state, but there hasn’t been an established population since the early 1900s1. Sightings of moose that wander over from Michigan or Minnesota are occasionally reported, but still rare.
That’s why our team was excited to discover several recent moose photos on our Snapshot Wisconsin trail cameras. We captured our first moose photo back in 2018 in Vilas County. In the past two months, we’ve had four additional sightings across several counties. It is unclear if this is the same individual, or several different moose.
Below are some photos of the moose captured in Iron, Price, and Burnett Counties.
We interviewed some volunteers who recently captured these moose photos on their Snapshot Wisconsin trail cameras. Steve from Price County said, “My initial reaction was complete shock. This camera check had been especially fruitful, and I had gone through quite a few pictures when the moose showed up on my screen. It was so drastically different in size and color to the deer we had been seeing up until that point that it took a second for my brain to process what I was looking at. My wife was sitting next to me and we both realized what it was at about the same time. I think she was even more excited about it than I was! We know there are moose that have been occasionally spotted in the state, but we never dreamed we would see one in our own backyard!”
When asked if seeing a rare species has impacted his experience as a Snapshot Wisconsin volunteer, Steve said, “It’s been a lot of fun this whole time but seeing a rare animal like this first-hand really makes it more exciting. The thought that we could potentially see something like this again is a great motivator!”
Amanda from Iron County said she was ecstatic when she first saw the moose pictures. “Even though it took nearly a year for me to finally capture a moose, I have spent countless hours hiking to and from my Snapshot camera and each trip out is an adventure. I feel blessed to live in such a beautiful area and enjoy such amazing wildlife, but the moose in particular have really drawn me in, and I am so lucky to live in an area where we can see them.”
Thank you to all of our volunteers who host trail cameras and help classify photos on Zooniverse. Your work helps us collect important wildlife data! If you’ve recently seen a rare species such as a moose, cougar, or lynx, please report it using the DNR’s Large Mammal Observation form.
