I need something that won't disturb my neighbours' and rid my large tree
of birds. They are making a terrible mess under the tree.

Thank you.


If you knew what species the birds were, you might be able to find a
recording of their warning cry or the cry of a predator bird to play
at regular intervals which might scare them off.
