Sono due specie diverse, che forse si possono incrociare. Appartengono al 'genus' deklle columbidae, con ciorca 300 specie ! Chi non e` ornitologo (studioso degli uccelli) e` ovvio che confonde i nomi. Nel mondo animale ancora non ci sono specie puramente maschili e specie puramente femminili, anche se ci possono essere specie asessuate, nel mondo microscopico. Thererefore, please, Mr. Fungo, try use you skepticism in the right direction! Here is the dove, PROPERLY said 'colomba' o 'colombo' (male) : http://www.projectnoah.org/spottings/8614087 with one of its several scientific name (being many species very similar): Dovius cloviuntas . The pigeons abound in almost any big Italian city, and I already described a pigeon in a previous question. I also find repeating myself. The point is that Google, and other sources of information just follow common knowledge, and in this particular case 'common knowledge' is not enough for your question! Specialized knowledge is what your question requires, so that a deep research is needed. Another source of ambiguity is that the pigeon, as a species belongs to the the bird family of the Columbidae, and the pigeon's scientific name is exactly: Columba livia domestica. BUT, the scientific name is another thing from the common name!
