Pigeons at the Ramesseum

Just a bit worrying to see all these pigeons at the Ramesseum. I was told that it was the result of bird flu when many people let their pigeons, which they raised for food, go. Whatever the reason there are now a huge number and we know the damage this does to stone work. I wonder if any one is looking at this and if there is a proposed solution.
