Black wildebeest
The black wildebeest or white-tailed gnu ("Connochaetes gnou") is one of the two closely related wildebeest species. It is a member of the genus "Connochaetes" and family Bovidae. It was first described in 1780 by Eberhard August Wilhelm von Zimmermann. The black wildebeest is typically in head-and-body length, and the typical weight is . Males stand about at the shoulder, while the height of the females is . The black wildebeest is characterised by its white, long, horse-like tail. It also has a dark brown to black coat and long, dark-coloured hair between its forelegs and under its belly.
White-tailed jackrabbit
White-tailed jackrabbits influence the composition of the turf through their selective grazing activities. They are important prey species for various mammalian predators. Red ("Vulpes vulpes") and grey foxes ("Urocyon cinereoargenteus") occasionally capture one, though not many large adults. They are perhaps most important prey for mid-sized carnivores such as the American badger ("Taxidea taxus"), the coyote ("Canis latrans"), and the bobcat ("Lynx rufus") and small supplemental prey for larger ones such as the mountain lion ("Puma concolor") and the gray wolf ("Canis lupus"). Snakes sometimes attack them (usually young ones) and bird predators include eagles, hawks, and owls. Golden eagles ("Aquila chrysaetos") are the only avian predators large enough to regularly take full-grown white-tailed jackrabbits, though ferruginous hawks ("Buteo regalis") and great horned owls ("Bubo virginianus") may occasionally take an adult, though these latter two species and other largish raptorial birds typically attack young. They attempt to evade detection by crouching in the vegetation where their cryptic colouration makes them difficult to observe. They may slink away, but if detected, they bound away at speed, adopting a zigzag course. They can run up to 55 km/hr (34 mi/hr) and leap up to . They are also hunted and eaten by humans.
