摘      要：Adaptive mate choice has been accepted as the leading theory to explain the colorful plumage of *** theory hypothesizes that conspicuous colors act as signals to advertise the qualities of the ***,a dilemma arises in that conspicuous colors may not only attract mates,but also alert ***private channels of communicationhypothesis proposes that some intraspecific signals may not be visible to heterospecific animals because of different visual *** better understand the evolution of plumage colors and sexual selection in birds,here we studied the chromatic difference and achromatic differences of melanin-and carotenoid-based plumage coloration in five minivet species(Pericrocotus spp.)under conspecific and predator visual *** found that either the chromatic or achromatic difference among male or female minivets’plumage was consistently higher under conspecific vision than under predator vision for all five studied species of *** result indicated that individual differences in plumage colors of minivets were visible to the conspecific receivers and hidden from potential predators as a result of evolution under predation risk and conspecific ***,males were under a higher risk of predation because they were more conspicuous than females to the vision of a nocturnal predator.
