Coevolution of elaborated male display traits in the spotted bowerbird: an experimental test of the threat reduction hypothesis
Article Abstract:
The features unique to the courtship behavior of male spotted bowerbird, Chlamydera maculata, were investigated and compared with the courtship behavior of other Chlamydera species. The courtship display behind a bower appears to reduce the threat associated with aggressive displays. Female spotted bowerbirds were shown to prefer males with more intense displays. Males and females consistently situated themselves on either side of the bower and the removal of a separating structure induce the reduction of the aggressiveness of the display behavior.

Mate choice in the grey partridge, Perdix perdix: role of physical and behavioural male traits
Article Abstract:
A study was conducted to determine the relationship between ornamentation and mating success in males of the grey partridge. Selected males with medium and large patches on their breasts were bleached and grouped into categories. Their mating success was determined by measuring their interaction with the females. The results showed that females preferred males with higher vocal performance. Males which had better acoustic characteristics and sound performance achieved higher mating success than males with better ornamentation.

Predation on females or males: who pays for bright male traits?
Article Abstract:
Male guppies, Poecilia reticulata, show bright color patches on their bodies in regions of low predation. The coloration is due to natural and sexual selection. The bright colored male guppies are consumed more by predators and get more matings. The female's preference for male coloration varies with local intensity of predation. The females from high predation areas prefer duller patched males.
