Pigeons Damaging the Sphinx

Description:

The common Pigeon has become quite a pest on the face of the Great Sphinx in Egypt. They land in large numbers and damage the rock structure and carvings with their claws and even worse, their acidic droppings. The droppings and the birds themselves also represent a visual distraction. When startled, clouds of the birds fly around the head of the Sphinx and then land again.

Notes:

In Mexico, Pigeons have become such a problem on ancient churches and monuments that most have now been covered in fine mesh or have rows of outward facing metallic spikes placed along all the ledges and crevices.
