I am on the last mooring
it is like a night club for the birds
not sure what to do about them
You need a plastic owl on the boom !
A couple of lengths of light line, which you string up from mast to stern rail (under the boom worked best for me). Tie on festoons of old VHS tape every foot or so along the lengths – the tape flutters in the breeze and keeps the birds away. Total cost approximately zero. Worked for me when I had an infestation of wagtails..!
In my experience, no!
Don’t use carrier bags as a deterrent. They blow off and pollute the environment.
I use the bird deterrent in the form of the vibrating nylon line that gardeners use. If you keep it tight from say the mast to the end of the boom and works in the lightest of winds, and the birds hate the noise. It works on my boat, and you can pick it up from most garden centres.
I have a customer that hangs a fake owl with large reflective eyes in his building doorway . it really stops the sparrows flying Ito his open workshop doors in the summer.
My brother in law tried everything for his old motorboat with a cover on a mooring on Lake Erie , what finally worked was the right 2 rubber snakes positioned in just the right way on the cover. It almost completly stopped the birds landing on the cover and crapping, and they had seagulls up there too.
Good luck

When I worked at ICI Wilton we had plastic owls mounted on the top of the fabrication sheds which I thought was a pretty good idea until one day when I saw a bludy big heering gull stood on one. NOT GOOD, the wretched birds used to dive bomb anyone walking around below for fear we would scale the buildings and take their young from the giant roof gutters. As if?

You could easily make one using an expanding pole rod bought for £10, some wire coat hangers, a binliner and some sticky back plastic
