Time Budgets and Consortships in Olive Baboons (Papio anubis)

Folia Primatologica, 1983
The influence of season, rank, consortships, and gender on the daily time budgets of adult free-ranging olive baboons (Papio anubis) are described. Neither season nor rank have much influence on time budgets. Females in consort reduce the time spent feeding while males in consort do not decrease feeding time, but spend more time feeding while moving ...

Consortship and Mating Success in Chacma Baboons (Papio cynocephalus ursinus)

Ethology, 2000
AbstractChacma baboons (Papio cynocephalus ursinus) show a lower consortship take‐over rate and longer consortship duration than the other savannah baboons (Bulger 1993). It has been argued that researchers have focused on atypically small troops with few adult males, resulting in low competition for access to oestrous females.

Male consortship behaviour in chacma baboons: the role of demographic factors and female conceptive probabilities

Behaviour, 2003
AbstractThere is evidence for a general relationship between male dominance rank and mating success in primates, although the strength of this relationship differs among species. In chacma baboons (Papio hamadryas ursinus) male rank is found to be of more importance than in the other savannah baboon subspecies.

Further evidence of a context-specific agonistic signal in bottlenose dolphins: the influence of consortships and group size on the pop vocalization

Behaviour, 2015
Pops are a low-frequency, pulsed vocalization produced by Indo-Pacific bottlenose dolphins (Tursiopscf.aduncus) in Shark Bay, Western Australia and are often heard when male alliances are consorting or ‘herding’ a female. Previous research indicated that pops produced in this context are an agonistic ‘come-hither’ demand produced by males and directed ...

Spatial Patterns and Peripheralisation of Yellow Baboons (Papio Cynocephalus) During Sexual Consortships

Behaviour, 1986
1. In free-ranging troops of savannah baboons, adult males form temporary pair bonds or "consortships" with females in oestrus. Consort pairs are characterized by unusually close and continued proximity and exclusive sexual interaction; such pairs are typically found on the periphery of the troop.

Social relationships between adult male and female rhesus macaques: 1. Sexual consortships

Primates, 1987
The sexual relationships of 15 adult male rhesus macaques (Macaca mulatta), of one social group in the Cayo Santiago colony, Puerto Rico, were studied during the 1981 mating season. Two criteria were used to determine whether or not a focal male was in consort in a given 20-min observational sample. One hundred and thirty-two consortships were recorded.

Sex differences in sexual partner acquisition, retention, and harassment during female homosexual consortships in Japanese macaques

American Journal of Primatology, 2004
AbstractFemale Japanese macaques (Macaca fuscata) in certain populations are unusual in that they exhibit male‐typical patterns of mounting behavior and sexual‐partner preference. The goal of this study was to determine whether female Japanese macaques, from one such population, employ male‐typical behavioral tactics to disrupt existing homosexual ...

Changes in the activity budgets of yellow baboons (Papio cynocephalus) during sexual consortships

Behavioral Ecology and Sociobiology, 1985
The energetic cost of guarding estrous females has been assumed to be a potentially major factor in limiting the duration of male consortships in a number of polygamous species. This issue has been examined in the present study by assessing changes in the usual activity budgets of 13 male and 20 female yellow baboons which occurred during their ...

Group-Living and Consortships in Two Populations of the European Rabbit (Oryctolagus cuniculus)

Journal of Mammalogy, 1987
Two populations of the European rabbit ( Oryctolagus cuniculus ) were investigated, at English sites, to determine whether polygynous, multi-adult groups formed in the absence of multi-entranced warrens. They did not. The small warrens were spread evenly across homogeneous patches and the females were dispersed.

Interventions and alliance formation between female Japanese macaques,Macaca fuscata, during homosexual consortships

Animal Behaviour, 1996
Abstract The purposes of this study were to assess whether homosexual behaviour promotes alliance formation between sexual partners and whether individuals engage in homosexual behaviour to form alliances. Data were collected during pre- and post-consortship baseline periods and during 21 of 28 different homosexual consortships observed ad libitum ...
