1. Majestic Antler Crowns: Male elk (called bulls) grow massive, branching antlers every single year. These giant head-dresses can grow up to four feet wide and weigh over 40 pounds—that's as heavy as a medium-sized dog sitting on your head!

2. Shedding and Regrowing: Every winter, male elk drop their heavy antlers off their heads. When spring rolls around, a brand-new, velvet-covered set immediately starts growing back even bigger and stronger than before!

3. A Name with a Mix-Up: In North America, these animals are called elk, but in Europe, the exact same animal is called a wapiti, which means "white rump" in the Native American Shawnee language. (In Europe, the word "elk" is actually used for what Americans call a moose!)

4. Super Loud Bugling: During the autumn mating season, male elk make one of the wildest sounds in the wild forest. They let out a loud, echoing call called a bugle that starts as a deep roar and finishes with squeals and grunts that can be heard for miles!

5. Giant Deer Relatives: Elk belong to the deer family, and they are some of the largest deer species in the entire world. An adult bull can stand as tall as a horse at the shoulder and weigh up to 700 pounds!

6. Master Jumpers: Even though they are huge and heavy, elk are surprisingly athletic. They can easily jump over fences up to eight feet tall in a single bound if they need to escape a predator or cross a pasture.

7. Hungry Plant Eaters: Elk are herbivores, meaning they don't eat meat. They spend most of their day grazing on fresh grass, munching on tasty leaves, and stripping the soft bark off trees to get the energy they need.
