Mate choice in satin bowerbirds has been studied in detail. Males build specialised stick structures, called bowers, which they decorate with blue, yellow, and shiny objects, including berries, flowers, snail shells, and plastic items such as ballpoint pens, drinking straws and clothes pegs. As the males mature they use more blue objects than other colours. It is theorized that the preference for blue objects is due to the colour accentuating the plumage of male satin bowerbirds or that the colour blue is more familiar and the designated colour for this species. Females visit these and choose which male they will allow to mate with them. In addition to building their bowers, males carry out intense behavioural displays called dances to woo their mates, but these can be treated as threat displays by the females. Nestbuilding and incubation are carried out by the females alone. Recent research has shown that female mate choice takes place in three stages: Visits to the bowers, before nests have been built, while the males are absent Visits to the bowers, before nests have been built, while the males are present and displaying Visits to a selection of the bowers, after nests have been built, leading to copulation with (typically) a single male. Experimental manipulations of the ornaments around the bowers have shown that the choices of young females (those in their first or second year of breeding) are mainly influenced by the appearance of the bowers, and hence by the first stage of this process. Older females, which are less affected by the threatening aspect of the males' displays, make their choices more on the basis of the males' dancing displays. It has been hypothesised that as males mature their colour discrimination develops and they are able to select more blue objects for the bower. It is not yet known whether this description would also hold true for other species of bowerbird. Male satin bowerbirds are known to destroy and steal from the bowers of one another. The quality of a male's own bower does not predict how often they will destroy others. However, males who exhibit more aggression by attacking others at feeding sites tend to destro ------------------------------ End of alt.music.moxy-fruvous digest V14 #11773 ***********************************************
