We have a pair of male mute swans living in a 2 acre lake, surrounded by public gardens. I am having trouble with aggressive behavior from the two males not conducive to the peaceful garden environment we are trying to create.

We procured the male pair 6 years ago so we would not have cygnets, which would either require care or finding another home.

Would a female pair be a better option for us?

Is sterilization possible for male and female mute swans?

Is sterilization for one of the males and obtaining a female, an option?

If I introduced a female of a different age from the male, would they bond?

What would you recommend?

Thank you for your help,
