Graceful until they walk on land .Ballets and stories feature around these 
birds and yet like all of living creatures , ( including humans) they have another  side .They can be extreme bullies .I'm enclosing a link to a video made when the family of 11 had a go at destroying a rats nest where it had a youngster .Bravo many may say .Rats and (Squirrels often referred to as cute )are very close cousins in the family Rodentia..Just watch if you wish and the rat has a rough time .Note this swan  family have territory ,raised 
nine young so rats never bothered them .In Berlin most rodents have a take away diet of  dumped  takeaways .Minus rats really awful .Young birds and and eggs are not needed :)
