The face is not the main consideration for the wedding gift

A recent study has revealed that birds of paradise do not consider the opposite face or the face when the mating season arrives.

Birds of paradise or known in Indonesia are renowned for their beautiful feather ornaments, their complex whistling styles and their movements that change often, all evolve for one purpose, namely to attract the attention of a partner .

Research published in the journal PLOS Biology explained for the first time that female tendon preferences encourage men to modify their behavior to attract physical attractiveness.

The combination of the two is finally linked to the location of mutual "teasing" between men and women, whether on the ground or on a tree.

The researchers report that, to date, there are 40 species of cenderawasih, most of them present in Papua and Northern Australia.

The study's lead author, Russell Ligon, a researcher at Cornell Lab of Ornithology in New York, United States, explained that the bawawaw women's group was of no importance to men, but that he was more interested in whistles and dancing whistles.

The researchers summarized women's preference for attracting men's attention as a pre-badual phenotype. That is, a collection of integrated traits determined by genetics and the environment.

Ligon searched for 961 videos and 176 audio recordings of memories from the Cornell Lab Library Archives.

In addition, they also studied 399 specimens from the American Museum of Natural History in the United States.

The research team and Ligon concluded that certain behaviors and properties had a correlation.

They wrote that the behavior and nature of male tendons to attract women's attention were correlated with the number of beautiful hair.

Then they also perform complicated dances because they have a wider repertoire of sounds.

Next, the researchers also revealed that male paradise birds had a different behavior in attracting the attention of females, depending on the location.

"The ground species dance more beautifully, while the whistle is softer," said Edwin Scholes, co-author of the study and Cornell Lab's Bird of Paradise Project Leader.

"In black forests, men may need to improve their dance movements to attract women's attention," he added.

Then, a bird perched on a tree with some twigs, leaves and shrubs, the male sings a complex tone. The goal is to be better understood by women.

However, they moved a little because they feared that the branches of the trees were shaking and broken.

Dr. Scholes, in collaboration with Dr. Tim Lama, a field biologist and photographer from Harvard University (USA), also studied the uniqueness of the gift of paradise to winter.

They study the paradise species found in Papua.

A total of 43 birds of paradise are incorporated into the family Paradisaeidaethe bird of paradise necklace (Lophorina superba) which has the same fleeting stature as the Vogelkop gift.

The cendrawasih neck is mostly composed of black fur. Then, the female has the majority of reddish brown color with a touch of yellow color.

When the mating season arrives, male males have different behaviors, including developing their black feathers to show their blue feathers on the chest.

Then the male will jump and dance in front of the female bird as a sign of invitation to the wedding.

"Dances to attract couples are different, different vocalisations, women look different, even male species are different," concluded Dr. Scholes.
