As confirmed earlier this month in a Pokemon GO news update by Niantic, the Research Breakthrough rewards are rotating now that June is here. After a long month of questing to earn multiple Zapdos encounters, it’s now time to bring in the big blue bird for a few weeks.

The Articuno encounter shouldn’t come as a surprise to anyone, since Pokemon GO officially confirmed the upcoming rotation earlier this month, but it is now definitely safe to claim the Breakthrough and feel assured that Articuno will appear, along with the other item and XP rewards.

In addition to the appearance of Articuno as a Breakthrough reward, players should also start picking up some new Field Research tasks that are associated with the theme of the Gen 1 Legendary's month. Although Articuno is an Ice- and Flying- type; this month's Field Research theme is actually all about Water-types.

At this point, Niantic hasn't hinted which Legendaries will come next now that all three of the original birds have arrived. If the Research Breakthroughs follow a similar pattern as the original Legendary Battle Raids; then it is likely that Lugia will be featured in July, but that's just a theory.

We'll be sure to post an update as soon as Niantic starts dropping hints about the July Research Breakthrough Rewards. Until then, good luck out there, trainers!
