Yellow-backed duiker
These forest dwelling antelope feed selectively on plants or plant parts such as shoots, roots, leaves, and buds, but their diet is mainly made up of fruits. The yellow-backed duiker is more efficient at digesting poor quality food than most other duiker species. This allows them to eat large, low quality fruits. Their diet makes them very hard to keep in captivity as most domesticated fruits are not well suited to their low fiber requirements. They are considered concentrate selectors, meaning they eat "diets relatively low in fiber, have a well developed ability to forage selectively, a rumen bypass, a rapid passage and high fermentation rate for starch, and they frequently encounter toxins."
Antelope Island State Park
Antelope Island State Park provides a habitat for a wide variety of wildlife. Despite its name, the park is most famous for its herd of bison. The size of the Antelope Island bison herd ranges from 550 to 700 animals and is controlled by an annual bison round-up. The Antelope Island bison herd is one of the oldest and largest in the United States. The park is also home to jackrabbits, pronghorn, bobcats, mule deer, coyotes, and several species of rodents. The island and Great Salt Lake attract migrating birds. The inland grasslands on the island provide habitat for chukars, burrowing owls, long-billed curlews and several species of birds of prey.
