Dove love with ears

Sexy sounds emanating from male pigeons can make doves enchanting, and the effect is even higher when the girls are watching the poses.

Because males often look at the claws and raise their voices at the same time, the results suggest that the male body is superfluous, because it also has the same function as sound, to help the male approach his partner.

People who communicate often incorporate signals, such as raising an eyebrow while asking: " Do you want to dance ?". Sharpening hairs can be ignored or misunderstood, but with facial expressions and words, will show what you want to say.

The sound of male pigeons alone is enough of a stimulating dose with female pigeons.

" The sound signals are very important to birds: when the children only listen and not see the males, they respond with inviting behaviors such as walking around and tailing, but the most important thing is that they speak nape, "study author Sarah Partan at the University of South Florida said.

Partan said the nape is an important activity because it stimulates ovulation in females. Humans often do not respond to such sounds, but flavors also affect women's periods.

Partan and colleagues investigated how 6 Carneaux white doves reacted to the sound and recorded image of a male trying to " please " the girl in the next cage.

In order to flirt, he bowed his head, leaned forward, ruffled his chest and raised a crow. When the children were watching this performance without sound, some of them stopped and watched the male, but others didn't seem to mind.

However, when only the male crow's ears were heard, most of the girls noticed. They react by spreading their tails. The strongest reaction is when the females have just been seen and heard the male, so the supposedly redundant behavior of the male still plays an important role.

" Animals use those redundant signals to increase efficiency, also to ensure the message is still sent in a noisy environment ," Partan said.
