You must realize though, that the Rock Dove, Diamond Dove, Ringneck Dove, and all domestic pigeon breeds have several different colors and patterns (except the Diamond, it keeps the same general pattern, as does the Ringneck unless it is pied). No two pigeons look the same really.There are also over 250 different breeds of domestic pigeons and many domestic dove breeds.Some are more common in some places while others are more common in other places. Homing pigeons, Rollers, and Fantails (all types) are probably the most common pigeons in general around the world. Almost everyone starts out with a pair of homing pigeons or rollers since they are beautiful in the sky, easy to take care of, and homers can be raced while the rollers can be in rolling competitions. Both breeds can also be shown, which adds a little extra.
