Adults are near the top of a food chain and are rarely preyed on. However, individuals are known to have been taken by jaguars and the much smaller ocelot Its main prey are tree - dwelling mammals and a majority of the diet has been shown to focus on sloths and monkeys. Research conducted by Aguiar - Silva between 2003 and 2005 in a nesting site in Parintins, Amazonas, Brazil, collected remains from prey offered to the nestling by its parents and after sorting them, concluded, in terms of individuals preyed upon, the harpy 's prey basis was composed in 79 % by sloths from two species: Bradypus variegatus amounting to 39 % of the individual prey base, and Choloepus didactylus to 40 %; various monkeys amounted to 11.6 % of the same prey base. In a similar research venture in Panama, where a couple of captive - bred subadults was released, 52 % of the male 's captures and 54 % of the female 's were of two sloth species (Bradypus variegatus and Choloepus hoffmanni). At one Venezuelan nest, the remains comprised sloths. Monkeys regularly taken can include capuchin monkeys, saki monkeys, howler monkeys, titi monkeys, squirrel monkeys, and spider monkeys. Smaller monkeys, such as tamarins and marmosets, are seemingly ignored as prey by this species. At several nest in Guyana, monkeys made up about 37 % of the prey remains found at the nests. Similarly, cebid monkeys made up 35 % of the remains found at 10 nests in Amazonian Ecuador. Other partially arboreal and even land mammals are also preyed on given the opportunity, including porcupines, squirrels, opossums, anteaters, armadillos, and even relatively large carnivores such as kinkajous, coatis, and tayras. In the Pantanal, a pair of nesting eagles preyed largely on the porcupine (Coendou prehensilis) and the agouti (Dasyprocta azarae). The eagle may also attack bird species such as macaws: At the Parintins research site, the red - and - green macaw made up for 0.4 % of the prey base, with other birds amounting to 4.6 %. '' Other parrots have also been preyed on, as well as cracids such as curassows and other birds like seriemas. Additional prey items reported include reptiles such as iguanas, tejus, and snakes.
