text: The bowers of different species of bowerbird can be characterised by the suite of colours that they use, with particular colours being selected either due to their rarity in the local environment (Borgia et al. 1987), their similarity to colours of preferred food items (Madden and Tanner 2003) or their contrast with the visual background of the bower (Endler et al. 2005).
