Tips for Safe Wildlife Viewing

To prevent disturbance and harassment of elk during the fall mating period and to enhance visitor elk-viewing opportunities, areas in Horseshoe Park, Moraine Park, Upper Beaver Meadows, Harbison Meadow, and Holzwarth Meadow are closed to the following acts from 5 p.m. to 10 a.m. daily:

• Foot travel off established roadways and designated trails or on closed roadways or trails.
• Fishing in those sections of Fall River, Big Thompson River, or Colorado River within the areas listed above are closed from 5 p.m. to 7 a.m.

Other Tips for Safe Wildlife Viewing:

• Elk can be seen anytime, a popular viewing period being the fall rut, or mating season. Look for elk in meadows and where meadow and forest meet.
• How close to too close? When viewing wildlife, follow the "Rule of Thumb." When viewing wildlife, make a thumbs up; extend your arm all the way; close one eye and see if you can hide the animal with your thumb. If you can still see the animal, you are too close. Take steps back until the animal is completely hidden.
• If wildlife approaches you, back away and maintain a safe distance. If a wild animal changes its behavior due to your presence, you are too close. 
• For animals like elk and bighorn sheep, keep back at least 75 feet, or two bus lengths.
• Harassing or feeding wildlife is illegal in all national parks.
• It is illegal to use artificial lights or calls to view or attract wildlife.

When we respect wildlife, viewing wildlife in their natural habitat is fun and rewarding!

View elk during the fall rut season.

 

North American Elk (Cervus canadensis)

Elk are one of the largest members of the deer family. Large males, called bulls, can weigh several hundred pounds and stand five feet at the shoulder. Females are called cows and are roughly half that size. A dark brown mane, light-brown bodies and white rumps characterize both sexes. They grow a thicker coat of hair each winter which they shed each spring.

Only males have antlers, which grow in the spring and drop each winter. Antlers can grow up to an inch a day. They are covered with a protective layer of velvety skin. When the antlers are fully grown, the bulls scrape this layer off.

 

Large elk herds occupy meadow valleys in autumn and winter.

Life History - Overview

Elk are highly social animals and travel in various herd sizes throughout the year. Herds can grow as large as a few hundred individuals. Elk have a large range and move according to seasonal food availability. In the summer, herds move to higher elevations to feed on tundra vegetation, while in the winter they move down to lower elevations of the park and down into the Front Range.

Large herds consist of cows, calves and young bulls (spikes). Older bulls remain in smaller groups or are solitary until the fall breeding season.

Life History - Elk Calves

Calving usually happens in tall grassy or brush areas away from the herd. Elk calves are born from late May into June and weigh about 30 pounds. Most cows give birth to one calf, but may also have two. Newborns have spots, which fade away by late summer. Calves can join the herd after two weeks and are weaned at two months old. Cows are extremely protective of their calves so use caution around elk at this time of year.

Elk primarily graze on grasses and forbs but they also browse shrubs. They feed mostly in the morning and evening, and seek sheltered areas during the middle of the day to digest. They eat an average of 20 pounds of vegetation daily.

Free roaming elk have a lifespan of 10-13 years in the wild.

Elk Rut - Mating Season

Every autumn, elk descend from the high country to montane meadows for the annual breeding season. Within the gathering herds, the larger antlered males, now weighing up to 1,100 pounds move nervously among the bands of smaller females.

In this season of excitement, bull elk compete with one another for the right to breed with a herd of females. Prime bulls, eight to nine years old, stand the best chance of mating. While competition is high among bulls, it includes little fighting, since fighting causes injury and depletes energy. Instead, mature bulls compete for cows by displaying their antlers, necks and bodies. They emit strong, musky odors and bugle. With little rest or food during the mating season, bulls enter the winter highly susceptible to the hardships of the coming months.

 

Call of the Wild - The Elk Bugle

Bull elk signal the beginning mating season with a crescendo of deep, resonant tones that rise rapidly to a high-pitched squeal before dropping to a series of grunts. The elk bugle gave rise to the term "rut" for the elk mating season.

• Fun Fact - Rut is derived from the Latin word meaning roar.

The eerie call echoes through the autumn nights and serves to intimidate rival males. Mating season is a stressful time for the animal, and the bugle may also act as a physical release of tension.

Cows and younger bulls may also bugle, but they cannot match the strength or range of the older bulls' calls.

• Moraine Park at dawn during the fall rut soundscape featuring Elk and Coyotes

  
  

  Moraine Park is a large open meadow at 8,160 feet in elevation. The Big Thompson river runs through the valley and it is home to numerous species of birds, mammals and fish. This recording, from the southwest part of the meadow, began at 5:40 AM and includes elk bugling and sparring during the rut, elk mews and coyotes barking. The first sounds can be heard at about 6 seconds into the recording.

History of Elk in Rocky Mountain National Park

North American elk, or wapiti, were once plentifulin the Rocky Mountain National Park area. As Euro-Americans settled the Estes Valley, they hunted elk intensively, sending much of the meat to market in Denver. By 1890 few, if any, elk remained.

In 1913 and 1914, before the national park's establishment, the Estes Valley Improvement Association and United States Forest Service transplanted 49 elk from Yellowstone National Park to this area. Around the same time, an all-out effort began to eliminate predators—including the gray wolf and the grizzly bear. The resulting decrease in predators and hands-off management of elk hastened the recovery of Rocky's elk population. The population grew to record high numbers in the late 1990's causing deterioration of vegetation and other wildlife communities.

The current Elk and Vegetation Management Plan addresses these issues. The plan's goal is to maintain a more natural population of 600-800 elk in the park's low-elevation valleys during the winter. Learn more about the Elk and Vegetation Management Plan.
