Some very interesting facts about Mute Swans, I was stunned when I read this.
Mates for life: Mute Swans usually mate for life, remaining together through the years, but “divorces” have been known, and if one of a pair dies, the survivor usually seeks out a new mate, and the pair remain devoted.
There are instances of swans "divorcing" and choosing new mates but research shows that the most successful breeders are established pairs.
A pair will normally use the same nesting site for many years.
Their life expectancy is at least 11 years with many living more than 20 years and some to 50 years.
