all diurnal african monkeys weigh in excess of in adulthood. cercopithecine monkeys are on the small side. full-grown female "cercopithecus" can range in average weight from and males from depending on species. all mangabeys and most colobus monkeys weigh considerably in excess of at maturity. any monkey of a weight of up to may reportedly be hunted. as a comparison, the heaviest primate known to be successfully killed by harpy eagles was a bolivian red howler ("alouatta sara"). the crowned eagle's diet may extend to the young or even (rarely) adult females of baboons and similar species, such as adult female yellow baboons, olive baboons ("papio anubis"), chacma baboons ("p. ursinus"), drills ("mandrillus leucophaeus") and mandrills ("m. sphinx"), all falling into the above maximum primate weight bracket and all have been successfully hunted. in some cases baboons and drills may be actively avoided, as the adult males of these species, at up to twice as heavy as the female, are probably invulnerable to hunting and tend to be notoriously violent-tempered. in one case, olive baboons destroyed the nest of a crowned eagle pair after one of the eagles killed a baby in the baboon group. when experimentally exposed to an image of a crowned eagle, a dominant male mandrill reacted aggressively towards it, implying that they will keep eagles at bay to protect the more vulnerable members of their troop. the crowned eagle is considered a potential predator of infant chimpanzees ("pan troglodytes") and bonobos ("p. paniscus"), although this is unconfirmed. although rarely observed, some monkeys will "bait" crowned eagles, that is harass and provoke them. leslie brown described sykes' monkeys ("cercopithecus albogularis") as rarely baiting eagles "with the insolent impunity of an expert tolero with a bull". struhsaker and leakey found that adult male monkeys were often better represented in the diet than adult females. this may be a result of the behavior of male primates. in some species, only adult males often travel separately from social groups, only adult males take aggressive action against eagles, and only adult males have loud calls that may attract the attention of eagles. the variation in behavior of primates is illustrated so that in red colobus species, in which adult males patrol in mixed groups, the males are rarely attacked; meanwhile in the black-and-white colobus, in which adult males often patrol alone, male are regularly attacked and killed by crowned eagles. however, adult monkeys (52%) were found in almost equal measure as juvenile monkeys (at 48%) in uganda. african primates weighing under , are almost entirely arboreal and nocturnal. however, such primates, actually allies of lemurs rather than monkeys, may occasionally also be hunted by crowned eagles. potto ("perodicticus potto") are notable secondary prey in the tai forest and various galagos have been found across the range, such as in the kiwengwa/pongwe forest reserve where they made up 7.5% of the remains. although no one has seen the eagles catch these primates, it is thought pottos and galagos are likely to be taken if discovered by an eagle while sleeping in dense foliage during the day.

communication of animals in the wild has been studied extensively. calls with specific intent, such as alarm calls or mating calls has been observed in many orders of animals, including primates. a study done on east african vervet monkeys showed that in the wild this species was able to produce at least 5 acoustically different alarm calls in response to danger, and that other monkeys responded differently according to which alarm had been sounded. this indicated a clear communication that there is a predator nearby and what kind of predator it is, eliciting a specific response. a different species of monkeys, the wild campbell's monkeys have also been known to produce a sequence of vocalization that require a specific order to elicit a specific behaviour in other monkeys. changing the order of the sounds changes the resulting behaviour, or meaning, of the call. diana monkeys were studied in a habituation-dishabituation experiment that demonstrated the ability to attend to the semantic content of calls rather than simply to acoustic nature. primates have also been observed responding to alarm calls of other species. crested guinea fowl, a ground-dwelling fowl, produce a single type of alarm call for all predators it detects. diana monkeys have been observed to respond to the most likely reason for the call, typically a human or leopard, based on the situation and respond according to that. if they deem a leopard is the more likely predator in the vicinity they will produce their own leopard-specific alarm call but if they think it is a human, they will remain silent and hidden.
