“…The animal that started the interaction, in most cases, became victorious. This result confirms those obtained in hens by Bronstein and Brain (1991), Collias (1943), Hogue et al (1997), Huntington Potter (1949), and Ligon et al (1990.…”

“…Behavioural acts evident at the onset of an encounter can also help to predict, with a high success rate, which subject will dominate. During an aggressive agonistic encounter, the animal offers the observer, in first-to-initiate or "first-to-attack" behaviour, valuable information concerning the subsequent agonistic behaviour (Bronstein and Brain, 1991). Of all the different factors observed in the present research, initiation of the encounter and the prior status of the adversaries were the best indicators of the hens' future dominance status.…”

“…In some cases, those behaviours could successfully foretell subsequent conflict issue. For instance, Bronstein and Brain (1991) have noted in the fish Cichlasoma nigrofaciatum that the future dominant always initiated the first aggressive agonistic behaviour of the meeting. Turner and Huntingford (1986), using the cichlid Oreochromis mossambicus, observed that circling-around and tail-beating behaviours could be used to predict, quite early in the encounter, which fish would win the fight.…”

Recent victory or defeat experiences and 2-hour familiarity with the meeting place were combined with size differences in order to better understand their effects on the behaviour leading to the establishment of dyadic dominance relationships between hens not previously acquainted with each other. Three kinds of encounters were videotaped: (i) a previous winner unfamiliar with the meeting place met a previous loser familiar for 2 hours with the meeting place (n = 12 dyads); (ii) as in (i) but both were unfamiliar with the meeting place (n=12); (iii) as in (i) but the previous winner was familiar with the meeting place while the previous loser was unfamiliar (n=13). The weight asymmetry was combined with these three types of encounters by selecting hens of various weight differences: in 29 dyads the recent loser was heavier than the recent winner and in 8 dyads it was the reverse. Recent experience had a major influence upon both agonistic behaviour and dominance outcome. Hens that were familiar with the meeting site initiated attacks more frequently than their unfamiliar opponent but did not win significantly more often. Recent experience and site familiarity could be used to identify 80% of future initiators. Once the first aggressive behaviour had been initiated, it led to victory of its initiator in 92% of cases. Weight was not found to influence agonistic behaviour nor dominance outcome. However, hens with superior comb and wattles areas won significantly more initial meetings than opponents with smaller ones. In the final encounters, victory also went more frequently to the bird showing larger comb and wattles, which happened also to be the previous dominant in a majority of cases. The use of higher-order partial correlations as an ex post facto control for comb and wattles indicates that they were not influential upon agonistic behaviour nor on dominance outcome, but were simply co-selected with the selection of victorious and defeated birds in the first phase of the experiment designed to let hens acquire recent victory/defeat experience.

“…Applying this model to cichlid fi ghting, lateral-display and tail-beating enable individuals to obtain information about the opponent's body size and the strength of the water current generated. When the fi ght escalates to physical contact, the fi sh that bites its opponent fi rst tends to win the fi ght ( Bronstein and Brain 1991 ) . If the fi sh recognizes that the opponent is larger and causes more powerful water current than itself, it will avoid further fi ghts to avoid injury.…”

“…It is known that separation of two convict cichlids by a transparent partition before fi ghting shortens the time spent in fi ghting rather than separation by an opaque partition (Keeley and Grant 1993 ) . When the fi ght escalates to physical contact, the fi sh that bites its opponent fi rst tends to win the fi ght ( Bronstein and Brain 1991 ) . Collectively, these results indicate that fi sh actually evaluate each other initially before involving in direct physical contact.…”

Aggression is one of the important emotional behaviors displayed by animals while acquiring and/or defending resources. Recent studies have revealed that peptide hormones modulate various social behaviors, including aggression, among vertebrates. Comparison among teleosts, birds, and rodents shows marked species differences in effects of peptides on aggression. A correlation between peptide function and social structure has been suggested to explain these differences; however, the species differences reported in part might also be due to the methodological differences among the studies. In teleosts, the action sites for peptide
