Doves and pigeons, in general, are the same thing. The word dove usually refers to a smaller species of pigeon, and what most people call pigeons are a type of bird labeled a feral rock pigeon. The idea of pigeons as annoying and dirty is a complete contrast to the symbolism of the dove. Doves are depicted as being messengers of peace and love.
