What do the spots on the feathers of peacocks?

Type of tail feathers in male peacocks and bizarre mannerisms wooing a female is likely to have a significant impact on their success in the mating season. These two features, as shown by the results of a recent study at the University of Queens, play an important role in attracting and mating with females birds.

Rose Daikin (Roz Dakin) and Robert Montogomeri (Robert Montgomerie) found that natural variation in the number of oculate spots on the tail of a peacock little effect on mating success of males. However, according to the observations of scientists, peacocks whose tails are endowed with a limited number of spots, are less successful during mating.

Refusal of females to males with reduced greatly the number of spots on the tails oculate can have many different explanations, including the perception of the maturity of the male, the overall size of his tail or even anxiety about the health of her female potential couples.

"Females may reject some males with a few spots in the feathers of the tail, taking into account any other considerations, choosing a mate for a long time among males with typical stains tails" - explained Professor Daikin, Ph.D., a four-year experience in the field of research into the nature and values of rainbow colors of birds. "It seems that other distinctive characteristics of colors and patterns of the tail is an important condition for selecting a pair of peacocks."

Mr. Daikin and his colleague Dr. Montogomeri, a professor from the Department of Biology at the University of Queens, in the end, tried to find out what to pay attention to females during courtship males. To achieve challenging goals, the researchers observed a long time for the marriage of birds games, marking for a variety of indicators. They studied the movements of peacocks, their behavior, the visits to males in the context of the plumage of males, and where males are located geographically.

"Courtship and sexual selection in these animals is undoubtedly very complex," - said Mr. Daikin. "There are numerous indicators for research, including multi-colored body and a pen that is on their minds. Males and females also tout engaged in energetic displays and demonstration of its plumage. Males are even taking certain positions to the rays of sunlight the most of their beautiful colors" .

This study was recently published in the journal "Animal Behaviour".
