If you're catching him as a random in another game, have a fire type Pokémon with you. Legendary Pokémon will pop up from time to time, so be prepared. If you're just trading a Zapdos from another game, go to a Pokémon Center and trade the normal way (Through the Union Room or Wireless room).
You can't get it in Pokemon Black. Use PokeTransfer or Dream World.
