difficulties feeding swans and ducks because seagulls are in the way and get the food...

hi all

i been going to a local pond for many years, and there is usually ducks and a couple of swans there. but over the past few months it seems there are lots of seagulls there now - either flying circling or sitting in the pond almost waiting.

i try and feed the ducks who are hesitant in getting close, so i have to throw the food to them. but when doing that, the seagulls swoosh in and take everything and the ducks end up with nothing.

i try and shoo them away by opening my umbrella or swing my bag in the air which causes the seagulls to fly off, and i try again, but eventually they come back.

any ideas on what else i can do?

thanks
