Thanks for the comments guys. I've called them swanlings for years, don't know why. Good to know the real name. (although from the reaction i'll probably keep calling them swanlings!!)
greensurfingbear and bambodoggy, a big thank you for that info, I didn't know that. I'll be more careful and keep my distance in future. I've been wathcing this group of swans for the last two years, (at least I think its the same swans) so I would hate to be the reason for any damage to their wellbeing.:sad6:
