First suspicions of the rare event were raised when male swan Sarindi turned up in the annual migration from Arctic Russia without his partner of two years Saruni and with a new female - newly-named Sarind - in tow.Sad and uplifting at the same time. Also, the parallel to humans is intriguing. Did they perhaps stop loving each other? I have, by the way, been blessed watching a couple of swans in Copenhagen caressing or dancing (or...?). They were necking, and I was spellbound. They looked like they were in love.
The pair's arrival led conservationists to fear the worst for Saruni.
But shortly afterwards Saruni arrived at the wetlands site - also with a new mate, Surune.
And after observing them, the experts discovered the old relationship had ended and new ones had begun.
As for why they may have split, she said: "Failure to breed could be a possible reason, as they had been together for a couple of years but had never brought back a cygnet, but it is difficult to say for sure."Not unheard of in humans, either, I suppose.
