  Title Learning and imitation as a function of social status in macaque monkeys (Macaca nemestrina) Type Journal Article
  Year (up) 1976 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 24 Issue 4 Pages 835-848  
  Keywords  
  Abstract Learning and imitation were examined in animals selected from two groups of sixteen pigtail monkeys. There were significant differences in performance on a cued-alternation task as a function of both social status within the stable group, and prior exposure to a social model. High status animals responded more frequently, but were less successful in acquiring appropriate response delay. Exposure to the model improved response latencies and acquisition of response delay for all subjects. However, model exposure did not improve alternation performance. Results are discussed in terms of prior social experience of the subjects, general learning strategies, and differential sensitivity to multiple reinforcement contingencies. Findings are related to ethological concepts of imitation, and field reports on primate social learning.

  Title Contrasts in social structure among black-and-white colobus monkey groups Type Journal Article
  Year (up) 1976 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 24 Issue 1 Pages 84-92  
  Keywords Agonistic Behavior; Animals; *Colobus; Copulation; Female; *Haplorhini; *Hierarchy, Social; Male; *Social Dominance  
  Abstract Three types of Colobus guereza groups may be distinguished on the bases of size and composition, namely small one-male groups, large, one-male groups and multi-male groups. The social structure of each type of group is described in terms of the distribution of non-agonistic interactions, the frequency and distribution of agonistic behaviour and the organization of the roles of vigilance, territorial defence and leadership. A number of differences are found between the group types which appear to be related to the differences in group size and composition. It is suggested that these group types represent stages in the life-cycle of colobus groups, and that such an interpretation may help to resolve some of the conflicting reports in the literature.

  Title The logic of asymmetric contests Type Journal Article
  Year (up) 1976 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 24 Issue 1 Pages 159-175  
  Keywords  
  Abstract A theoretical analysis is made of the evolution of behavioural strategies in contest situations. It is assumed that behaviour will evolve so as to maximize individual fitness. If so, a population will evolve an [`]evolutionarily stable strategy', or ESS, which can be defined as a strategy such that, if all members of a population adopt it, no [`]mutant' strategy can do better. A number of simple models of contest situations are analysed from this point of view. It is concluded that in [`]symmetric' contests the ESS is likely to be a [`]mixed' strategy; that is, either the population will be genetically polymorphic or individuals will be behaviourally variable. Most real contests are probably asymmetric, either in pay-off to the contestants, or in size or weapons, or in some [`]uncorrelated' fashion; i.e. in a fashion which does not substantially bias either the pay-offs or the likely outcome of an escalated contest. An example of an uncorrelated asymmetry is that between the [`]discoverer' of a resource and a [`]late-comer'. It is shown that the ESS in asymmetric contests will usually be to permit the asymmetric cue to settle the contest without escalation. Escalated contests will, however, occur if information to the contestants about the asymmetry is imperfect.

  Title Models of parent-offspring conflict. I. Monogamy Type Journal Article
  Year (up) 1978 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 26 Issue Pages 97-110  
  Keywords  
  Abstract Theoretical models for Trivers (1974) concept of parent-offspring conflict are examined for species in which the effects of the conflict are felt by full sibs. A rare conflictor gene will spread if Image , whereÆ’(m) is the fitness gained by a conflictor relative to a non-conflictor offspring (Æ’(m) >1), and m is the amount of parental investment taken by a conflictor relative to m = 1 for a non-conflictor. The range of m alleles which can spread against the parent optimum decreases as the cost to the parent increases until a point is reached where there is no conflict of evolutionary interests. There would be no polymorphism for conflictor: non-conflictor alleles unless special conditions prevail. The conflictor allele which spreads most rapidly as a rare mutant against the parental optimum is not an evolutionarily stable strategy (ESS). The ESS for parent-offspring conflict in monogamous species has m0 = Æ’(m0)/2[dÆ’(m0)/dm0]. The analytical solutions are confirmed throughout by simulations.

  Title The practical problems of recognizing and measuring fear and exploration behaviour in the domestic fowl Type Journal Article
  Year (up) 1978 Publication Animal Behaviour Abbreviated Journal Anim. Behav.  
  Volume 26, Part 2 Issue Pages 422-431  
  Keywords  
  Abstract In studying behaviour supposedly motivated by fear or by exploration, consideration should be given to the biological functions of these two systems and to the ways in which the experimental environment may affect the performance of ‘natural’ responses. Extreme caution is needed in comparing the effectiveness of different stimuli and the amounts of fear or exploration represented by different responses. In particular, it should never be assumed when making such comparisons that the relative intensities of different stimuli and responses are constant.

  Title The logical stag: Adaptive aspects of fighting in red deer (Cervus elaphus L.) Type Journal Article
  Year (up) 1979 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 27 Issue Part 1 Pages 211-225  
  Keywords  
  Abstract For red deer stags, fighting both has appreciable costs and yields considerable benefits. Up to 6% of rutting stags are permanently injured each year, while fighting success and reproductive success are closely related, within age groups as well as across them. Fighting behaviour is sensitive to changes in the potential benefits of fighting: stags fight most frequently and most intensely where potential benefits are high and tend to avoid fighting with individuals they are unlikely to beat. The relevance of these findings to theoretical models of fighting behaviour is discussed.

  Title The foraging efficiency of great tits (Parus major L.) in relation to light intensity Type Journal Article
  Year (up) 1979 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 27 Issue Part 1 Pages 237-241  
  Keywords  
  Abstract I report an experiment aimed at testing whether foraging efficiency of great tits is limited by light intensity at the time of the dawn chorus. Captive great tits hunting for prey under different luminance conditions were less successful in finding prey when foraging, hunted for a lower proportion of their time, and handled individual prey items for longer when luminance was under approximately 7 cd/m2. This luminance is not reached in the field until after the time of the dawn chorus, suggesting that in the early morning foraging is limited by light intensity. I suggest that a satisfactory functional explanation of the dawn chorus must take into account the comparatively low foraging opportunity early in the morning, as well as the factors affecting the opportunity for singing and other territorial activities.
