Can't catch zapdos in sapphire
Yes, all 3 of them (Articuno, Zapdos and Moltres) will be in Pokémon HeartGold and Pokémon SoulSilver.
The legendaries on Soulsilver are as follows: Entei, Raikou, Suicune, Lugia, Ho-oh, Groudon, Latios, Rayquaza, Mewtwo, Moltres, Articuno, Zapdos. These are the legendaries found on Pokémon Soulsilver version. ~CareyPrice31FTW
Lugia,Ho-oh, Raikou, Entei, Suicune, Latios, Mewtwo, Zapdos, Moltres, Articuno, Groudon.
It's your opinion, but in HeartGold you can catch Ho-oh, Suicune, Raiku, and Entei, and in SoulSilver you can catch Lugia, Zapdos, Moltres, and Articuno. There are also more Pokemon available in HeartGold than SoulSilver. Edit: The person who last answered this question is wrong, you can catch all of the above Pokemon in both games, not in either or. I know this because I have soul silver and I have suicune, raiku, Entei, Ho-oh, Lugia, Zapdos, Moltres, and Articuno; so obviously you must be able to catch them in both.
