You can capture Zapdos from the Powerplant.
You will need Surf, And you need to go to Route 9 from Cerulean City, All the way to the PokeCenter.
Above the Center, there is some Water where you can Surf down to the Powerplant.
Just sole the Labyrinth, and get Zapdos!
Remember to save in front of it!
