Swan likes adultery

Swans have long been seen as symbols of eternal love and loyalty. But in fact, Australian researchers found that they were cheating, often sneaking out of the nest to "outside the moon".

DNA testing shows that 1 in 6 swans is a product of a thief - this breaks the image of the monogamous union of the bird.

Now, researchers at the Department of Zoology, University of Melbourne are trying to figure out how the females manage to walk in front of their partners - who are famous for their ability to protect the nest - to search for "left-handed" love.

The experiment was performed with black swans. 60 males at Albert Park Lake in Melbourne were fitted with a tiny microchip into the tail feathers. In contrast, females are fitted with a mini tracking device, known as a decoder.

" When a male and a female mate, the female's decoder will recognize the microchip on the male's tail, register the code for 'guy' as well as the time of lovemaking, " said Dr. Raoul Mulder, chief The team said.

" All the mating will be recorded on the decoder. After a few weeks, we captured the swan and downloaded the perfect recording of the offspring's offspring ."

Mulder said the study looked at the black swan because their bodies were big enough to wear tracking devices, and the number was much richer than the white swans entered into the continent.

In addition to providing an overview of swans 'sexual behavior, research can reveal the female partners' complex sexual choices, Mulder said.

" Pairing with other swans is always accompanied by dangers, so this behavior must definitely have some evolutionary benefit, " he said.
