Royal antelope
A herbivore, the royal antelope prefers small quantities of fresh foliage and shoots; fruits and fungi may be taken occasionally. Though the antelope is considered to be nocturnal, zoologist Jonathan Kingdon holds that feeding occurs throughout the day, though some foraging may also be observed at night. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles. These features do not allow complete digestion of lignified growth. Individuals may often move into new locations foraging for fresh growth.
Andean condor
The Andean condor is a scavenger, feeding mainly on carrion. Wild condors inhabit large territories, often traveling more than a day in search of carrion. In inland areas, they prefer large carcasses. Naturally, they feed on the largest carcasses available, which can include llamas ("Lama glama"), alpacas ("Vicugna pacos"), rheas ("Rhea ssp."), guanacos ("Lama guanicoe"), deer and armadillos. Wild individuals could acquire extra carotenoids from vegetal matter contained in carcass viscera and fresh vegetation. However, most inland condors now live largely off of domestic animals, which are now more widespread in South America, such as cattle ("Bos primigenius taurus"), horses ("Equus ferus caballus"), donkeys ("Equus africanus asinus"), mules, sheep ("Ovis aries"), pigs ("Sus scrofa domesticus"), goats ("Capra aegagrus hircus") and dogs ("Canis lupus familiaris"). They also feed on the carcasses of introduced game species such as wild boars ("Sus scrofa"), rabbits ("Oryctolagus cuniculus"), foxes ("Vulpes vulpes") and red deer ("Cervus elaphus"). For condors who live around the coast, the diet consists mainly of beached carcasses of marine mammals, largely cetaceans. They will also raid the nests of smaller birds to feed on the eggs. Andean condors have been observed to do some hunting of small, live animals, such as rodents, birds and rabbits, which (given their lack of powerful, grasping feet or developed hunting technique) they usually kill by jabbing repeatedly with their bill.
