The Roosevelt Elk have different names and purposes when it comes to their gender and what stage they are at in life. Males are called
bulls and the females are called
cows, while all offspring are called
calves. Only until calves reach maturity of about 2 years of age is when they are fully identified as either a bull or cow. During Elk
rut, the mating season of the species in the late summer and early fall, bulls attempt to outcompete each other to gain dominance among a small group of cows. While physical dominance over each other through aggression and fighting can be used, bulls commonly use the stature of their antlers, necks, and bodies to establish dominance. Since they are a large species, the elk often only reproduce a single calf once a year in the spring. Before the calf joins the herd, they stay camouflaged with spots gained from birth during the first few weeks to avoid predators until they are strong enough to forage and protect one another. The Roosevelt Elk can live up to approximately 15 years in the wild, but can reach up to 25 years under human care. In 2018, the
New York State Zoo had a Roosevelt elk named Rosie die in August of that year at the
age of 26, which means it was one of the oldest at that time. ==See also==
