	abstract = {<p>We tested the status-signaling hypothesis in two groups of same-age and same-sex Harris\&$\#$39; Sparrows (Zonotrichia querula). Unlike flocks of mixed age and sex composition, badge size did not correlate with social status of these groups; thus, status signaling does not appear to occur within age-and-sex classes of Harris\&$\#$39; Sparrows. Other predictions of the status-signaling hypothesis we tested were that (1) fighting ability and social status should be correlated, and (2) fighting ability and badge size should be correlated. We used a multi-variate assessment of body size as an indicator of fighting ability and found no support for either prediction in the flock of adult females. In the flock of adult males, large birds were more dominant (Prediction 1) but fighting ability and badge size were not correlated (contra Prediction 2)</p>},

	abstract = {<p>Two new methods for quantitatively describing behavioural processes of hierarchy formation in large groups are introduced. These methods supplement those already available with the jigsaw puzzle approach to hierarchy formation and they examine behavioural sequences in component triads, subgroups of three individuals, making up the larger group. The first method gives a new procedure for counting various kinds of attack sequences in component triads, and the second traces how relationships evolve in triads. Used together, the procedures can help explain the development of dominance structures, and in particular, what kinds of interactions produce those that are linear or near-linear. The methods are illustrated by applying them to large flocks of Harris\&$\#$39; sparrows, Zonotrichia quereula, having 12-17 members, during hierarchy formation. This application indicates that different behavioural mechanisms may be involved in hierarchy formation for large and small groups and that some configurations of interactions in triads are much more stable than others, namely, transitive ones are much more resistant to reversals than intransitive ones. These findings suggest that earlier and later interactions may not be independent and raise a number of interesting questions about individual-level mechanisms operating during hierarchy formation</p>},
