Elk at Dawn Lower Mammoth 9996
A bull elk tasting estrus pheromones at dawn in the hills southeast of Lower Mammoth.
Estrus pheromones are produced during the estrus cycle, which only lasts a day or two, although if the female is not bred during this period she will have another cycle three to four weeks later. Bull elk taste the pheromones to determine if a particular cow is ready to mate.

Elk at Dawn Lower Mammoth 0075
A bull elk poses for a close portrait in the hills southeast of Lower Mammoth in northern Yellowstone. Elk in Yellowstone National Park are Rocky Mountain Elk, one of four subspecies in North America.
Elk are one of the largest animals in the deer family, and are only surpassed by the moose. Elk were originally named by early European explorers who thought that they resembled a moose, so they gave it the name elk which was the common name for European moose. The native Shawnee name for the animal was Wapiti (literally: white rump), and this name is used for Asian subspecies because in Eurasia the name Elk is still used for the Eurasian moose.

Elk Herd at Sunrise Lower Mammoth 0233
A bull elk drives his harem across a valley at sunrise in the hills southeast of Lower Mammoth.
During the breeding period, a mature elk can acquire a harem of up to thirty or more cows, about half of which are in prime breeding condition. There may also be a yearling bull (known as a spike for its single point antlers) or an older but less mature hanger-on, a young bull who is attracted to the herd but is subordinate to the dominant bull. This herding pattern only occurs during the rut.
During the summer, cows, calfs and yearlings usually run in large herds, and bulls are either solitary or run in small groups of two or three. In the winter, bulls congregate in bands known as bachelor groups, and the cows, calves and immature bulls run in herds numbering in the hundreds.
Elk in the Greater Yellowstone area take part in the longest elk migration in the continental US. Elk in the southern Yellowstone area migrate to Jackson Hole, WY to winter in the Elk Refuge. Elk in the northern areas of Yellowstone migrate to lower altitudes in north and west Montana.

Elk Herd at Sunrise Madison Meadow 1269
A bull elk (resting at far left) and his harem in a meadow near the Madison River at sunrise.
During the breeding period, a mature bull elk can acquire a harem of up to thirty or more cows, about half of which are in prime breeding condition. There may also be a yearling bull (known as a spike for its single point antlers) or an older but less mature hanger-on, a young bull who is attracted to the herd but is subordinate to the dominant bull.

Elk Bugling at Sunrise Madison Meadow 1312
A bull elk bugles to his harem at sunrise in a meadow along the Madison River in the west end of Yellowstone National Park. Elk bugle in different ways for several reasons: to communicate to their harem that they are in the area, to warn the cows that they are straying too far, and aggressive calls to other bulls that they are getting too close to the harem or as a challenge to the other bull elk. The sound of a bugling elk is distinctive, beginning low in the throat and rising to a whistling scream, then falling to a series of hollow grunts. The primal scream of the bugling elk is as identifiable as the sound of a howling wolf. It awakens ancient aboriginal memories and once you have heard this haunting cry you will never forget it. Female elk (cows) are attracted to bulls which bugle louder and more often, so during the fall rut the sound is omnipresent.

Elk Bugling at Sunrise Madison Meadow 1321

Elk bugle during the rutting period which occurs from late August through early October. The breeding period, or rut, occurs primarily in September, but may begin in mid-August or extend into mid-October.

Elk Gibbon River 8755c
A bull elk with an exceptionally wide rack of antlers poses at the edge of the Gibbon River below the Grand Loop Road in Yellowstone National Park.
Antlers grow from two pedicles, which are specialized bone-follicles on the head. Every spring, layers of cartilage called velvet antlers grow from the pedicles. Antlers grow faster than any other animal bone, and can grow up to an inch a day. They are covered with velvet, a vascular skin which provides blood, nutrients and growth hormone to the developing antler. Antlers grow from the tip, and the cartilage below is gradually mineralized into bone. Once the antler has reached full size, the velvet falls away or is rubbed off, and the bone dies. The mature antler retains grooves showing the path of blood vessels from the velvet, and North American Elk antlers can weigh up to 40 pounds and have a spread as wide as four feet.
Antlers differ from Horns in several ways:
Horns are a layer of Keratin (like fingernails and hair) over a living bony core. Antlers are true bone structures. Horns are slow-growing and permanent (not shed each year). Antlers are fast-growing and are shed each year. Horns are usually grown by both sexes. Antlers are usually grown only by males (except for reindeer or caribou). Horns are usually single tines, often curved or spiral, and exhibit annual growth rings indicating an animal’s age. Antlers are associated with testosterone and are often branched. The number of tines do not indicate the age.

Elk Portrait Madison River 0842
An extreme close portrait of a female elk at the Madison River.
Note the horizontal pupil. This is a common feature amongst prey animals, whose eyes are on the sides of their heads. While this eye placement gives poor depth perception, the combination of the eye placement and horizontal pupils gives prey animals an extremely wide angle view of their surroundings. Predators typically have their eyes placed in front of the head, giving them binocular vision which increases depth perception and allows them to better judge distances, and their pupils are either vertical or round. The horizontal placement of pupils in grazing species allows the pupil to be vertically oriented when grazing, increasing their depth of field when their head is lowered to graze. Predators with slit pupils have vertical pupils since they hunt with their head raised, so this gives them the best depth perception when hunting.
Round pupils permit a clearer image at night compared to slit pupils, as they are able to maximally dilate and receive light from any direction. Round pupils lack the ability to close quickly in bright light and do not block excess light as well as slit pupils. When constricted they reduce the amount of light available from the higher frequencies of the spectrum (blue light). A slit pupil allows the entire diameter of the lens to be utilized, even in bright light, and drastically reduces the amount of light during the day. Slit pupils are able to constrict more rapidly as well.

Elk Norris Junction 9177
Charger, a renowned 6 point bull elk, poses near the Norris Ranger Station in Yellowstone.
This 6 point bull elk is actually the second to carry the name. The original Charger was an 8 x 6 point bull elk in the Norris Junction area who was killed by an illegal hunter in 1993. The poacher was turned in by a taxidermist who recognized Charger’s antlers from a magazine article and contacted investigators. 6 point Charger, with his distinctive shoulder scars, was named for his habit of charging at tourists who get too close.
