You are right they do mate for life. Often a pair will take over a body of water and not let any other swans on it. That is why they run their children off in about February so that they can start the process all over again!

We have been wondering whether guineafowl are the same. Because we think it's the same pair each year. The hen has some very distinctive features.

A male and female guinea fowl are normally monogamous—which means that they pair with each other for life and mate with no other individuals.

So I think then it is the same pair you see each year 😁

Ah, you did the homework I was too lazy to do! Thank you!

Hehe my pleasure, I do like to do the odd spot of searching 😀
