Field Notes

Jackson Hole Wildlife

by Monica RobinsonJul 12, 2024

When you enter the famed Jackson Hole, be prepared to be enchanted by the wild, rugged valley and surrounding majestic mountains. Marvel at the towering Tetons, breathe in the crisp, fresh air, and revel in the wide, sprawling landscape blanketed in untamed sagebrush, lush forests, and the meandering Snake River. Your senses come alive as you immerse yourself in pristine nature- a wild place that awe-inspiring species call home.

Thanks to the range of different habitats that scatter across the sprawling valley, there is a plethora of wildlife to be found. The forests house woodland creatures like foxes, mule deer, black bears, pine martens, and elk. The sagebrush steppes are the stage for pronghorn antelope, bison, grizzly bears, sandhill cranes, coyotes, and several hawk and falcon species. The rivers and lakes are the places to look out for beavers, otters, swans, pelicans, bald eagles, and moose. Due to the mountainous landscape, steep rock faces are a seemingly impossible playground for bighorn sheep, mountain goats, and pika. The ever changing topography and characteristic native vegetation promise a rich and assorted abundance of life where anything is possible!

Summer Season

The summer months see the majority of visitors traveling to the valley in search of spectacular wildlife sightings. School vacations and warm, sunny weather draw people from across the country and around the world to relish in the spectacular hiking, refreshing lake and river adventures, and world class fly fishing. What almost every visitor shares in common is the sheer excitement at witnessing the wildlife roaming our public lands.

The summer season is considered to be between the months of May and October. Conditions vary greatly throughout these months with certain species appearing more commonly than others. In May and June, anyone with high hopes to see a grizzly will want to be in the park around this time. Bears are still low in the valley after emerging from hibernation, and this is their breeding season. Sightings are most common at this point! It is also the time where elk are plentiful, having their calves. Moose are calving also, and are more active during these cooler days than the proceeding hotter months. The majestic bald eagle is a frequent sight on the landscape year-round.

While July and August heat up the valley, the melting snow opens up high elevation habitats that many bears, moose, and elk take advantage of. They become far more scarce as they move up to higher ground for cooler temperatures and better grazing. Some do stay down in the valley, so sightings are still possible, but require a bit more luck! They move around far less in the midday sun, taking shelter in the dense forests to cool off. Bison and pronghorn are in their element during these months as they are far more heat tolerant than other species, staying active throughout the day. The bison rut is an exciting time to observe them- the bulls are actively pursuing mates, showing off with booming bellows and aggressively wallowing (rolling in the dirt) to impress the females. Hundreds upon hundreds of bison can be seen in the valleys, and even right on the roads!

September and October cools off again, encouraging more movement in our crepuscular species. The leaves on the cottonwood and aspen trees begin to turn gold, transforming the valley into a painted fall masterpiece. These are the months you should expect to hear the magical elk bugle through the trees, and admire the fully grown antlers. Moose are a common sight now, and bears become more visible again as they increase their feeding to pack on the pounds for the upcoming winter.

Winter Season

Many see winter as a time where the park shuts down, and the prime winter activities are skiing and cozying up indoors. While these are excellent options, there is still plenty of wildlife to be seen amongst the snowy landscape!

The beginning of the season is a time for animal migrations and settling into annual winter ranges. Elk migrate to the National Elk Refuge in the thousands from all over the valley, and even from as far as Yellowstone! Once the migration is over, you can see up to 8,000 elk on the open fields of the refuge. The National Elk Refuge was established in 1912 in order to provide the elk with protected wintering grounds. The development of the town of Jackson cut off their migration corridor to their usual winter ranges. With this access lost, they began dying off at a rapid rate. This prompted the establishment of the refuge which is still used today, and is an excellent wildlife watching experience between November and April.

Take a horse drawn sleigh ride into the refuge to get up close to the elk herds and learn all about their winter survival. Coyotes are frequently seen nearby, and foxes appear as an occasional treat hunting for rodents under the snow. Bald eagles perch in the bare trees, surveying for prey. Exploring behind the refuge around Miller Butte, you will see Rocky Mountain bighorn sheep- an animal that is an extremely rare sight in the summer months! These natural acrobats spend their time high up on steep mountain faces, but deep snow pushes many of them down to these habitual wintering grounds, providing an exciting wildlife experience for us.

You won’t see bears during these months as they are, of course, hibernating, but this is the season to keep your eyes peeled for the gray wolf. Elk are their usual prey, and hunting an animal of such great size is hazardous. In the winter months when the elk are at their weakest, this is when the wolf thrives. They utilize the deep snow to wear out the already weakened elk, making them easier to take down. The snowy backdrop is perfect for wolf watching as their darker coats are more visible against white than they are in the summer sagebrush.

Moose are a winter resident that loves the cold. Due to snow depth, they are forced to move out of their summer ranges and typically congregate around areas with vegetation still sticking up over the surface. Unlike in the summer months, it is difficult to drive around the sagebrush flats and not see a moose!

Best Way to View Wildlife

Grand Teton is a spectacular place to see wildlife, but it can be intimidating when you don’t know where to start. Unlike a zoo, there are no guarantees that you’ll see anything, but your odds go up when you have an understanding of the habits of wildlife and know the best places to look in the park. This is why taking a guided tour is one of the top activities that visitors book during their trip. Going with a local guide arms you with the expert knowledge of the ecosystem that will put you in the best position to encounter the incredible wildlife you were hoping for while learning all the fascinating facts about them that you never knew!
