(Newser) – A pair of British swans has done the unthinkable for the loyal species, which usually mate for life: It split up. Sarindi and Saruni had been together for two years, but both returned to an English bird sanctuary from their annual Arctic migration with brand new partners. It's only the second time in a 40-year survey of 4,000 pairs that researchers at the center have observed a swan “divorce.”

Both new couples are co-habitating on a small lake, but the old flames have yet to acknowledge each other’s presence. Researchers find the development “bizarre.” Typically, "as long they are both still alive, they will try to stay together," one tells the BBC. As for the case of Sarindi and Saruni, "failure to breed could be a possible reason" for the split.
