The use of a dove as a symbol of peace originated with early Christians, who portrayed baptism accompanied by a dove, often on their sepulchres. The New Testament compared the dove to the Spirit of God that descended on Jesus during his baptism.

We don't consider doves as pests but as pets in different parts of our continent. Eat, yes people do eat them though, and as far as poop is concerned I agree doves do that more than dogs and cats.

The symbol is rich in meaning and is the pre-eminent symbol of peace. Shown in this mosaic is a dove with an olive branch in its beak with wings outstretched for flight, and above the dove are dark menacing clouds. The bird is flying towards a brighter horizon seeking a peaceful refuge.
