Some Pokemon GO players are finding unusually rare spawns in their world maps. Pokemon GO is known for having astronomically rare spawns for legendary Pokemon such as Articuno, Moltres, Zapdos, and more. Players will usually find one of the bird trio by using their daily adventure incense. Fans hoping to have a second chance to catch the legendary birds can search in places they’ve seen them before, as they have a higher chance to spawn in those areas.
