On the bird-poop statue question.



Rather than the expense of a coating I did think of perhaps a long thin metal rod at the back fixed to the bronze base with an expanded metal or similar bird repellent small canopy just above the head.
Then a funny thing struck me (but did not trickle down my back)...
The lower statue does not seem to have suffered as the one in the foreground. This may be because of the proximity to the building and whether there is bird-repellent mesh/spikes on the building. The birds, in the huff, may tend to stick close to where they wish to be?
More study needed? Off you pop.
