As Niantic's augmented reality game, "Pokemon Go," become more challenging for trainers to achieve the ultimate goal of completing the Pokedex and dominating gyms, the game developer is rumored to start a rotation on rare Pokemon nests regularly until the end of September, which could spur more patience for players in hunting rares.
According to iDigitalTimes, nests are different from the random, regular spawns that happen in the game. Nests are places on the map where a massive amount of the same Pokemon will spawn on a consistent basis. However, if players are walking down a street and a Pidgey pops up, it is not likely that a Pidgey nest is nearby since Pokémon Go randomly drops Pokémon around the world, and some players have been able to guesstimate what will show up.
Furthermore, come this August, some players were disappointed to find that major Dratini nests, for example, suddenly became Eevee spawns instead. Heavy reported that certain nests that were commonly inhabited by rare Pokemon have moved or "migrated" elsewhere, as Niantic "felt it was too easy to catch these high-leveled species."
Now, if Niantic decides to move the rare Pokémon nests regularly, the search for rare pocket monsters will pose more difficulty to trainers. Prior to the already head-scratching way of capturing rare monsters, the rotation is believed to be make things a lot harder for "Pokémon GO" players. That is why catching Dragonite will probably be more challenging than before since it has an average spawn rate of 0.0011% which translates to about one in every 100,000 Pokémon spawned.
Meanwhile, Heavy obtained a Google Maps document where users provide major nest locations for other players to map out the specific species they want. In fact, the document is being updated regularly, and though there are not too many updates available yet, it is a good start for those who want to check on rare Pokémon nests.
Via Silph Road, a collection of Pokémon Go enthusiasts, a global map of spawn points that happened on August nest migrations is cited in Reddit, while they also continues to map out Pokemon nest changes so players know exactly where to go to find their dream Pokémon.
