The swans 'divorce' to find new partners

Experts at a wildlife sanctuary in Gloucestershire, England witnessed a "rare" divorce between a pair of swans to pair up with their new lover.

This is the second couple in more than 4,000 swans of Bewick swans after they are living together, recorded by the Wildfowl and Wetlands center for 40 years.

Sarindi and Saruni swans have been together for 2 years. The Sarindi male swan - flying back from the far north - does not go with his ex-partner who is dating a new swan Sarind.

Soon after, the Saruni female also came to the flooded area and became acquainted with her new Surune friend.

Under the scrutiny of experts for a long time, the old relationship between Sarindi and Saruni has ended and each side has a new affair.

Julia Newth, the Slimbridge Wildlife Health researcher, said the special situation surprised the staff of the center.

Sister Julia Newth said: 'Usually, swans tend to be faithful to a partner throughout their lives. When both of you are still alive, they will always be together. If they change their mate, only one child can die. '

In this case, both swans and new partners live together through the winter on Lake Slimbridge and generate some problems. 'A pair of swans that once lived together had no sign of recognizing or greeting each other even though they still lived not far away on a small lake,' Newth added.

Explaining why they broke up, Newth said: 'The failure of childbirth can be the cause of divorce. Over the years, we observed, these swans still have no children. But we are not sure about this. '

Bewick swans are the smallest and rarest of the three species found in the UK and each swan has its own characteristics by a special pattern on the mine.
