Birds not only to build the nests and noisy cause to bother, but also due to transfer of variety disease into human, especially when it drops any place and then this deposit dried and them particles distribution in the space. This problem is important for the investigation of environmental health and conservation aspects. Nevertheless their nests are suitable place for ectoparasite that is hazardous for humans healthy. Recent researches about the effect of biodeterioration of birds dropping showed that the rate of acid content and soluble salts of dropping is about 4% and with this interaction specialty by porous limestone rock due to damage chemicals, dissolved minerals, salts dissolved and etc. in this review article, we investigate the damage role of birds dropping on stone surfaces and considering Bird control method to eliminate or deter pest birds from landing, roosting and nesting.
