Sable antelope
Sable antelope live in savanna woodlands and grasslands during the dry season, where they eat mid-length grasses and leaves. They visit salt licks and have been known to chew bones to collect minerals. They are diurnal, but are less active during the heat of the day. They form herds of 10 to 30 females and calves led by a single male, called a bull. Males fight among themselves; they drop to their knees and use their horns.
Antelope Island bison herd
Antelope Island in Great Salt Lake, Utah, is part of Antelope Island State Park. On the island, a semi–free-ranging population of American bison ("Bison bison, "buffalo) has been in existence since 1893. Though the island was named for the pronghorn antelope that John C. Frémont and Kit Carson found there when they explored the Great Salt Lake, bison were later introduced and the island is now perhaps most famous for its bison herd.
