Comments

I think that there is a man in a house on route 7 that shows you them, but I'm not sure

Answer 1

No, you must transfer them from Pokémon Dreamradar, or you must trade from Pokemon Black/white, there is no other option.

You can buy Pokémon Dreamradar on the eshop(Nintendo 3ds)

Answer 2

Yes you can. Bcorr is right. A man on route 7 shows you a picture of either Thunderus or Tornadus, depending on the game.But if you want the info in the pokedex, you must obtain them.
