Sparrow droppings

From: Konrad Zehnder <zehnder>
Date: Friday, September 8, 2000
The painted stones of the main portal of the Berne cathedral
(Switzerland) are affected by excrements of pigeons and sparrows. A
wire fence has been installed which keeps off the pigeons, however,
it is not efficient to keep off the sparrows which are still soiling
the oil painted figures. The situation does not allow to close the
open hall adequately. Therefore, we are searching for an
installation to scare away the sparrows. Who does have such
experience and remedy?
