Ho-Oh is a special event Pokemon who can be caught when you obtain a Mystic Ticket and travel to Navel Rock. Of course, you can always play Pokemon Colosseum (for GameCube) and transfer Ho-Oh to LeafGreen. If you mean Hoothoot, the owl Pokemon (known as Hoho in Japanese), it cannot be caught in Pokemon LeafGreen. You must trade for one from Emerald, as it is caught there in the Safari Zone.
