Signals in intra-sexual competition between ring-necked pheasant males
Article Abstract:
The role of male ornaments in male-male agonistic encounters was investigated. Head ornaments appeared to be the most effective sexual ornaments among female ring-necked pheasants. Head ornaments, which include ear tuffs, function as coverable signals to rival males that informs readiness to fight, fighting ability and resource-holding power. The total time spent of displaying correlated with testosterone level, physical condition and rank of the male ring-necked pheasants.

The role of bright plumage in male-male interactions in the ring-necked pheasant
Article Abstract:
Plumage brightness is used by male pheasants, Phasianus colchicus, to assess the quality of competing males. This finding goes against the traditional assumption that plumages are used by females in mate selection. It seems that male-male interactions may have played a role in the evolution of plumage brightness. The brightness and pigmentation of male plumage can be involved in intra-sexual competition for resources which is found all year round in male-male groups.

Female choice for morphological features of male ring-necked pheasants
Article Abstract:
A study of the mate selection behavior of a sample of captive female ring-necked pheasants revealed their selection of males to be based more on the males' capacity to provide them with adequate protection from predation and less on factors such as indirect genetic or territorial benefits. Tail length, length of the ear tufts and the presence of black spots in the wattle positively influenced selection patterns of females.
