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%).
Verreaux's eagle-owl
Reptiles and amphibians are occasional prey for Verreaux's eagle-owls. Various snakes have been included in their diet ranging from the small, innocuous brown house snake ("Boaedon fuliginosus") at to large and venomous Egyptian cobras ("Naja haje") weighing over . Frogs were amongst the prominent prey recorded for suburban-breeding eagle-owls in South Africa, namely the African red toad ("Schismaderma carens") and the guttural toad ("Amietophrynus gutturalis"). Unidentified frogs were fairly significant in the diet from Kenya. The largest herpetological prey known is the Nile monitor ("Varanus niloticus"), at a mean mature mass of , these primarily diurnal reptiles can provide a fulfilling meal but can be hard to subdue even if ambushed unaware. Predation on fish has been reported but no fish have been observed firsthand in dietary studies. A surprisingly wide range of invertebrates have been reported in the diet for this species. In some cases, they may prey on insects as small as termites and even smaller invertebrates have been recorded in pellets such as orbatid mites and "Sarcophaga" flies, but are likely consumed incidentally while eating a larger item, either from carrion or the stomach of the prey itself. Unidentified scorpions, spiders and millipedes have also been reported in their foods. Most attacks on insects involve large ground beetles or dung beetles. Verreaux's eagle-owl has been known to feed on dung beetles among herds of African buffalo ("Syncerus caffer") by night, boldly diving below the massive bovids’ legs, and will readily feed on beetles among elephant dung when available.
