You can catch Zapdos in the Power Plant.
The easiest way is to put Zapdos to sleep, do damage with your ice or rock types. You can't catch Zapdos unless it's asleep and its HP is down to almost nothing. Use an Ultra Ball. If it wakes put it back to asleep. Change to a weaker pokemon and keep damageing. Repeat until caught. I'd go into battle with at least 20 Ultra Balls. Hope this helps.
All you have to do is go alone back through the dungeon that Zapdos is found, and battle it again. When you beat it, there is a chance that it will join you.
you might not be able to catch a zapdos in those games but if you have fire red you can catch him at the power plant once you have surf and then transfer it on to your other game.
you have to trade from red blue or yellow. zapdos is not catchable in Pokemon silver.
