I intentionally didn't use the phrase "Flock of Seagulls", as growing up in the 80's myself I knew that reference would be made. It was worth the laugh though.
They must not have made much of an impact on spawning as I have millions of tiny fry now visible.
For geese, red driveway reflectors have worked for me. I do need to move them and mix them with other deterents occasionally.
