Yellowstone park notes:

Elk “Antlers are usually symmetrical and occur on males and, only rarely, females.

•The average, healthy, mature bull has six tines on each antler, and is known in some parts of the US as a “six point” or “six by six.”

•One-year-old bulls grow 10–20-inch spikes, sometimes forked.

•Two-year-old bulls usually have slender antlers with four to five points.

•Three-year-old bulls have thicker antlers.

•Four-year-old and older bulls typically have six points; antlers are thicker and longer each year.

•Eleven- or 12-year-old bulls often grow the heaviest antlers; after that age, the size of antlers generally diminishes.”

“The antlers of a typical, healthy bull are 55–60 inches long, just under six feet wide, and weigh about 30 pounds per pair.”

(The wingspan of an eagle is also about six feet.)

Elk are not horse-sized deer, or grown up deer, they are a different animal, but both deer and elk (and moose) are in the deer family (Cervidae).

Hear elk bugling.

In A Field Guide to Mammal Tracks, Olaus Murie described an elk bugle, or as he called it “Wapiti music: … It rises with a glide to a high-pitched silvery note, then glides down again, to end in some guttural grunts.”

In his memoir Teewinot: Climbing and Contemplating the Teton Range, Jack Turner, Exum guide and corporate president writes: “The sound the bull elk makes during the rut is, everyone agrees, difficult to describe. The word bugling leaves too much to the imagination, but attempts to be more specific usually end up being humorous. The early English hunters were particularly eloquent and fanciful. Sir Price said: ‘It is a decided whistle, not unlike a soft note on a clarinet, ending with a very mild sort of grunt at the finish–a most difficult sound to describe, but one which I am happy to say we became very familiar with before the hunt was over. It is the most gentle musical sound that emanates from any animal I ever met with.’

“Not to be outdone, Baillie Grohman said: ‘It is very hard to imitate, or describe. It is neither a whistle or a bellow. Not unlike some tones produced by an Aeolian harp, it might also be compared to the higher notes produced by the flageolet, and of course it is entirely different from the red deer’s call.’

“Olaus Murie’s description in The Elk of North America is, in the best tradition of American pragmatism, more prosaic, but it rings true: ‘The call begins on a low note, glides upward until it reaches high, clear, buglelike notes, which are prolonged, then drops quickly to a grunt, followed by a series of grunts. The call may be very roughly represented thus: A-a-a-a-ai-e-eeeeeeeee-eough! e-uh! e uh!’”

Please note it is against park regulations to imitate an elk bugle or wolf/coyote howl
or use any artificial or natural audio attractants (including rattling antlers)
to attract or disturb wildlife.

Moose are the largest in the Cervidae – Deer Family, 6.5 to 7.5 feet tall, (one source says 5 1/2 to 7 1/2 feet at the shoulder) with antlers that spread 4 to 5 feet (record 6’9″) and can weigh up to 1,400 pounds (usually 1,000 male, 900 female (cow). Lives up to 20 years.

Moose calves live with their mother until the cow begins estrus (around 18 months after birth of the calf).

moose pair

male and female moose
moose fur is made up of two different layers

“Moose . . . have thick fur coats with long hollow hairs to insulate them down to temperatures of -60F. This also makes moose fur tremendously buoyant. All the air molecules trapped in moose fur do what air wants to do in water – rise to the surface. So the coat of a moose acts as a lifejacket, a constant force that tugs the moose to the surface.”
. . . moose are incredible swimmers, at least as hoofed animals go. They are capable of hitting speeds of at least six miles per hour. That sounds like no more than a jogging speed for humans, but most humans can only swim two miles per hour. High School swimmers hit three to four miles per hour. Olympic swimmers win medals above five miles per hour.” Is from https://www.tetonscience.org/can-moose-really-dive/

NPS photo pronghorn: Pronghorn Male (buck) weighs 100–125 pounds; female (doe) weighs 90–110 pounds, adult length is 45–55 inches and height is 35–40 inches at shoulder. (can run 30 mph for 15 miles with spurts up to 70 mph, another surce says can run for sustained sprints of 45–50 mph) from the Smithsonian “communicate with each other visually by raising the mane on the back of the neck into a stiff brush and erecting the white hairs on their rump”)

Newborn pronghorn fawns can walk within 30 minutes of birth and are capable of outrunning a human in a couple of days.
The park service notes that “A pronghorn buck (male) is easily distinguished from a doe (female) by his black cheek patch.”

Both male and female bison 4-5 feet tall at their shoulder, 10-12 feet long, have a small beard, but only the male has a bushy forehead. Males (2,000 lbs/900 kg) are larger than females (1,100 lbs/500 kg).

Yellowstone park says:

Q: How do you tell male from female bison?

A: A bull’s head is wider and shaped more like a triangle than the female bison; its ‘forehead’ fur is much thicker, as is the fur on its forelegs; and its beard is thicker. A cow’s horns are slightly more curved and slender than a bull’s. In addition, a cow’s shoulders are narrower than its hips while a male’s shoulders are broader than its hips.

In the NPS photo below, the female bison is on the left, the male on the right.

from a Yellowstone National Park report:
“Despite their size and seemingly slow moving habits, bison are surprisingly agile and can be quick to react.”

This photographer might have thought he was far enough away because he had a wall between him and the bison, but bison (1,000 to 2,000 pounds) are capable of hopping quickly over walls:

From a distance it can be hard to tell which small animal you see swimming. But each swims differently.

Muskrat swimming:

muskrat in water

Beaver swimming:

beaver in water

River otters undulate through the water. One source says when a beaver swims, only his head shows above the water; muskrats show both their head and part of their back. Another source says that muskrats usually swim with their thin tails “snaking in the water behind them or arched out of the water; you never see a beaver’s tail as it swims.”

Muskrats (Ondatra zibethicus) have been observed swimming underwater for up to 17 minutes, surfacing for three seconds, and then going back underwater for another 10 minutes. Adult muskrats are the size of a football, (their body 16-24 inches long, long narrow tail 7-11 inches),

Otters (Lontra canadensis), are 3 to 4 feet long,
Otters can remain submerged for several minutes, dive to 55 feet and swim up to a quarter-mile underwater.

Otter “Ears and nostrils close when underwater; whiskers aid in locating prey.”

three otters in shallow water
beavers (Castor canadensis) are four times as big as a muskrat. (Beavers reach lengths of three to four feet and weights of up to 40 pounds and can live up to 24 years in the wild.).

Beavers use their tails as rudders as they swim, to slap the water when they want to warn other beavers they see something dangerous (like you, perhaps) and to help them stand up to reach for and chew branches.

A Yellowstone study found that cougars (mountain lions) mostly eat elk, followed by mule deer, bighorn sheep, and pronghorn. They may live up to 18-20 years.

Learn about research sponsored by the Yosemite Conservancy and “follow a mountain lion’s journey on a summer morning in Yosemite.” You can see that video cameras detected mountain lions all over Yosemite Valley.
https://storymaps.arcgis.com/stories/3e36ebd9b63d4489b2254c94617887de

The lab results of scat samples “for 2019 revealed that 35 individual mountain lions were detected in Yosemite: 14 females, 10 males, and 11 cougar samples without individual or sex identified.”

Also a predator, also not commonly seen, the Pine Marten, (Martes americana) NPS notes: 18–26 inches long, is active throughout the year; hunts mostly on the ground. Rests or dens in hollow trees or stumps, in ground burrows or rock piles, in excavations under tree roots.

NPS notes: Ringtailed cats “are known to invade buildings in search of food or to hunt rodents, but they are strictly nocturnal and make every effort to avoid detection. Ringtails weigh only about two pounds and can be up to 32 inches long, adding another 12 or more inches for their fluffy, ringed tail.

Combining their small size and incredible agility, there are few spaces inaccessible to a determined ringtail. Using their semi-retractable claws they can climb most walls and perform cartwheels and other acrobatics to negotiate tight spaces.”

Below a NPS drawing showing the size comparison of a wolf, coyote and a fox.

And another National Park Service drawing comparing the size and coloration of a fox (front), coyote (center), and wolf (back), by Michael Warner from a Yellowstone Park webpage

National Park Service drawing of a fox ( front) coyote ( center) and wolf ( back), by Michael Warner from a Yellowstone Park webpage

Coyotes have a narrow, triangular shaped head. A wolf has a more square, blocky head.

Wolves can be coal black, creamy white and everything (gray, tan) in between. Coyotes are gray, tawny, buffy or reddish gray, with some orange on it’s tail and ears.

The coyote often holds his tail between his legs when running. His nose is more pointed than a wolf.

A red fox barks, but rarely howls/sings. Wolves and coyotes both sing long howls, but the wolf does not add yips/yaps. Yellowstone park notes that that wolves howl for “intrapack communication, advertising territory, coordinating social activities.” Denali park notes that “Wolves are noted for their distinctive howl, which they use as a form of communication. Biologists do not know all of the reasons why wolves howl, but they may do so before and after a hunt, to sound an alarm, and to locate other members of the pack when separated. Wolves howl more frequently in the evening and early morning, especially during winter breeding and pup rearing. Howling is also one way that packs warn other wolves to stay out of their territory.”

To print a wolf / coyote comparison go to:

http://www.nps.gov/grte/parkmgmt/guideres.htm

and click on wolf versus coyote comparison

Coyote front prints are usually 2 3/4 inches in length or less, some large dog breeds can have prints as big as a wolf, wolves are usually 3 1/2 inches in length not including the claws.

The International Wolf Center tells us that “The biting capacity of a wolf is 1,000 to 1,500 pounds of pressure per square inch… In comparison, a German Shepard has a biting pressure of 750 pounds per square inch. A human has a much lower biting pressure of 300 pounds per square inch.”

___________________________________

The coyote (Canis latrans), (25 inches tall, large ones up to 55 pounds) compares in size to a large family dog. One way to tell if what you see from a distance is a dog or a coyote is that when a coyote runs, it generally holds its tail down at an angle, and a dog runs with its tail up. We’ve read that Rocky Mountain coyotes are bigger than the ones we frequently see in Yosemite on our winter trips.

Average 43 inches long.

A Gray Wolf (Canis lupus), up to 35″ tall, is much bigger than a coyote or family dog, but it can be hard to tell at a distance, which is where you will most likely see one if at all. Wolves can weight 70-120 pounds, coyotes only 25-40.

Wolves run on the average 5 mph, or up to 35 mph.

First photo below of mollie’s wolfpack in Yellowstone: (in social situations like the first photo, the height the tail is carried generally relates to the social status of that wolf).

The main differences between a grizzly Ursos arctos and a black bear Ursus americanus are:

Two photos below black bears and six of grizzlies are courtesy of NPS:

NPS webpages have noted:

grizzlies have a dished, or concave face; black bears have a straight facial profile

grizzlies have a large hump of muscle above the shoulders (used for digging and running) This hump is higher / taller than their rump.

grizzly claws (long, for digging) are visible from a distance, black bears claws (short, curved for climbing) are not

grizzlies are bigger (males 300-700 pounds, black bears 210-315 pounds) but an adult male black bear can be bigger than a female griz

coloration in both is so variable, that it isn’t a good way to tell them apart. Black bears are not just black in color, they can be light, medium or dark brown, cinnamon/reddish or blond. Grizzlies can be any of the above, sometimes with silver-tipped guard hairs that give them their grizzled gray / silver appearance.

If you have reason to report a bear sighting, try to notice the color as described above, including any colors of patches on the chest or of girth bands. Be ready to describe the size. A two year old is about 1/2 to 3/4 the size of a female, a yearling about 1/4 to 1/2 the size of a female and the cub of the year is about 1/4 the size of a female. Was there an ear tag, radio collar or paint to identify the bear?

black bears are more likely to stalk a human than grizzlies, although this is quite rare

both can climb trees

grizzly bears can run 40 miles per hour, black bears more likely run 30 miles per hour

In the Yosemite Daily Report it said: Bears can run as fast as 35 mph.
The average human athlete runs at around 15 mph,
and the fastest known human (Olympic gold medalist, Usain Bolt) runs at 27 mph.
Bears win.

both hibernate, but sometimes awake during winter and leave their dens (occasionally some black bears in Yosemite, for example, never do hibernate)

both have occasionally become too used to humans and/or human food and have had to be destroyed.

What do Grizzly bears sound like? Griz vocalizations description from Yellowstone Park “Grizzly bears sometimes vocalize when agitated or nervous.. . sounds of huffing, jaw-popping, and low growls are warnings that you’re too close.”

Grand Teton National Park rules say do not approach wildlife, stay 100 yards from bears or wolves and 25 yards from other wildlife including nesting birds. If you have an accidental, surprise or inadvertent closer encounter with wildlife you must remove yourself to those distances.

For your safety while wildlife viewing, stay 25 yards away, at least, for most wildlife, and 100 yards for bears, moose, elk, bison and wolves, whether on foot or in your car.

Keep the animal’s line of travel or escape route clear and move away if wildlife approaches you.

How far away is 100 yards? Picture the length of a football field without the end zones.

25 yards? picture four car lengths or six kayak lengths, or the width of an Olympic-sized pool like ours at the college.

NPS drawing of a human and various animals showing how far away we need to stay from wild animals

row of buses depicting distance to stay away from animals

Safe Distances from Wildlife includes reasons to stay away from even friendly seeming animals in parks, and charts and photos to better be able to determine and visualize how far away from wildlife you need to stay to be safe (and obey laws that do have penalties).

Grand Canyon National Park rangers say: “Follow the rule of thumb: if you can cover the entire wild animal with your thumb you’re at a safe distance. This distance is usually 25 yards from most wildlife and 100 yards from large wildlife . . . If you are close enough to take a selfie with an animal, you are too close. ”

Selfies can be great, OR dangerous. The use of cell phones for photography (with or without a selfie stick) has made preventable injury or even death by selfie common. They were only taking a selfie.

Parks Canada warns, along with keeping a proper distance from animals :

“If you spot the following defensive warning signals, pull back even more or leave the area:

Bears make a ‘woofing’ noise, growl and snap their jaws;
Bull elk and moose put their heads down and paw at the ground;
Cow elk flatten their ears, stare directly at you and raise their rump hair.

If you cause an animal to move, you are too close.”

This NPS photo came with this warning:
“when a moose is stressed it will lay its ears back along its head and its hackles will rise.”

moose showing agitation

• Denali National park warns: “Moose are not predatory, and they will not try to eat you.
Instead, they try to trample a perceived threat.”
   

You will really want your own binoculars.

and a telephoto lens for your camera.

Using a drone for your photography is illegal in national parks. NPS notes: “Drones can be extremely noisy, and can impact the natural soundscape. Drones can also impact the wilderness experience for other visitors creating an environment that is not conducive to wilderness travel. The use of drones also interferes with emergency rescue operations and can cause confusion and distraction for rescue personnel and other parties involved in the rescue operation. Additionally, drones can have negative impacts on wildlife nearby the area of use, especially sensitive nesting peregrine falcons on cliff walls.”
