Thank you. I am new to swans and very keen to learn. I identified the difference between the male and female by their beak - maybe I have made a mistake. I am more concerned about the remaining cygnet. I noticed when the other cygnets were learning to fly and this one didnt join in so I think I will call the RSPCA. I have given my email address so if you have any factsheets or articles about swans I would be very grateful to receive them.
