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%).
Texas antelope squirrel
"A. interpres" nests in burrows or in crevices amongst rocks, usually close to bushes or shrubs. Within the United States they are found in western Texas, and in parts of south central New Mexico. They are also found in northern Mexico, including in the Chihuahuan Desert. Because of the wide range of their habitat, they are listed as least concern by the IUCN Red List. While they are commonly found within pockets of the United States, they are common throughout their range within Mexico. Their main threat from humans comes from accidental trapping or poisoning within the United States, although they are eaten in some parts of Mexico.
