Thank you for the quick response.
I’m happy to report that the female swan(?) appeared today with all 7 cygnets at the end of the creek close to the nesting area. The other 3 swans (I cannot really tell if they are adults or not, but the are full size) are still around, closer to the entrance of the creek. So far no sight of the male swan around the female.
I suppose its possible that the couple moved their nest although they were always around the same spot for at least the last 12 years since we moved in our home.
I’ll keep you posted.
