Mandrill
The mandrill is an omnivore. It usually consumes plants, of which it eats over a hundred species. It prefers to eat fruits, but will also eat leaves, lianas, bark, stems, and fibers. It also consumes mushrooms and soil. Carnivorously, mandrills mostly eat invertebrates, particularly ants, beetles, termites, crickets, spiders, snails, and scorpions. It will also eat eggs, and even vertebrates such as birds, tortoises, frogs, porcupines, rats, and shrews. Mandrills likely will eat larger vertebrates when they have the opportunity, such as juvenile bay duikers and other small antelope. Large prey are likely killed with a bite to the nape with the mandrill's long canines. One study found the mandrill's diet was composed of fruit (50.7%), seeds (26.0%), leaves (8.2%), pith (6.8%), flowers (2.7%), and animal foods (4.1%), with other foods making up the remaining (1.4%).
James Bernard Harkin
The pronghorn antelope was another large Canadian mammal believed to be on the verge of extinction. In 1910, the pronghorn antelope was moved from the Banff Paddock into Wood Buffalo National Park. Harkin believed the animal would benefit in a new protected park area. In March 1912, the park reported the presence of fourteen antelope. However, the effort was unsuccessful as the pronghorn antelope population decreased due to a lack of proper diet. In 1915, Harkin continued to play an essential role in antelope preservation near the village of Nemiskam, Alberta, where about 200 starving antelope were found in a rancher near the village of Foremost. The antelope were removed and sent to a reserved area of Maple Creek, where sufficient food and resources were available . On December 18, 1915, Minister William James Roche approved the formal reservation of seven square miles of land and established the Nemiskam National Antelope Reserve. In 1917, the American Permanent Wild Life Protection Fund recognized Canada as the first country to create a fenced preserve for antelope. In 2012, the pronghorn antelope can be found in southern Saskatchewan and Alberta.
