I guess they're quite same when you look to them. :).
The main difference between pigeons and doves is their size. For example, the largest species of pigeons is the Crowned Pigeon of New Guinea. They are almost 2-4 kg.
In weight; doves are smaller, for example, the New World Dove which weighs 22 gm. Most all pigeons and doves eat fruits and seeds, but some doves, like Quail Doves and Ground Doves, also feed on worms and insects. The tails of pigeons are more rounded in shape whereas the tails of doves are more pointed.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
