A field study of wild mountain gorillas was conducted to elucidate details of sexual initiation required for an interpretation of the increased frequency of copulation during the menstrual cycle, in comparison to the wild, that occurs when this species is tested in traditional laboratory pair tests. Although females in the wild played a clear role in establishing and maintaining proximity to the male and assertively presenting for copulation, all female presenting was preceded by some form of behavior by the male. Although originally described as male aggression in the laboratory tests, such behavior now appears to be male sexual initiative, elicited by female proximity. The exaggerated form and frequency of the display in the laboratory, and the increased copulation during the cycle that ensued, are likely due to 1 placing females in proximity to a male daily, rather than on 2—3 days of estrus as occurs in the wild, and 2 the inability of the female in the laboratory to withdraw from male proximity during pair tests in a single cage. In addition to clarifying the data on laboratory pair tests, the data on wild gorillas have relevance to the captive breeding of gorillas.

Studies of the behaviour of 26 12 males and 14 females captive infant and juvenile lowland gorillas showed clear sex differences. Females showed greater interest in young infants and were more active in nest building as well as in solitary and social grooming. Males were more active in locomotive, dominance, and aggressive behaviour and in social play. Hand-rearing further increased aggression. Males were more aggressive when they lived with only one partner, and they rose in rank even above older females, a pattern that has not been observed in naturally reared gorillas.

Sexual initiation in wild mountain gorillas

Female gorillas have been documented engaging in lesbian sex for the first time. The behaviour was observed by scientists during a research trip to the Rwandan section of the Virunga mountain range in central Africa. The wild mountain gorillas, observed by a team led by Dr Cyril Grueter of the University of Western Australia, are believed to gain pleasure from having sex and may do it when they have been rejected by males.
By Ewen Callaway. Female gorillas use sex as a tactic to thwart their rivals, new research suggests. Pregnant apes court their silverback male to stop other females conceiving.
