Browse Repository Browse E-Theses. Animal Behaviour, ISSN Studies of personality typically test subjects in isolation, ignoring the potential effects of the social environment, which might restrict the expression of individual behaviour via conformity, or enhance it by Invividual. The Gouldian finch, Erythrura gouldiae, exhibits polymorphism in head colour red or black which is related to different personalities: black-headed birds are bolder and less aggressive than red-headed birds.

INTRODUCTION

As Indivixual, this species provides a unique opportunity to investigate the effects of the presence of a social partner on the expression of individual behaviour. This social conformity effect was reduced, however, for black-headed birds paired with red-headed partners in the novel object test; in keeping with previous research findings, bolder individuals were less plastic in their responses. Since variation in personality can promote group cohesion and improve the functioning of social groups in a variety of contexts, we hypothesize that head colour could act as a cue, facilitating preferential associations with those of similar or dissimilar personalities in large mobile flocks of Gouldian finches.
