"Pikachu Signaling Nest Changes?"

#PokemonGO: So with the past three migrations, I've noticed something interesting. Each time a migration happened, I discovered Pikachu spawning in the nests in the hours leading up the the migrations.The first time I noticed this, I was going to one specific nest every day after work knowing it would soon change. The day the nests actually changed, two Pikachu spawned. I thought at first that the nest was just changing to Pikachu, but realized later that night it was something else altogether.The next nest change, I happened to go to two different nests the day they changed. Both of them spawned a Pikachu in the hours prior to the changes. Last night, I was going back and forth between two nests again, and noticed Pikachu making an appearance at both.This may just be a really strange coincidence, but these are nests I frequent quite a bit and never see Pikachu spawn there. Has anyone else ever seen this? Wondering if it may be one of those little hidden game secrets. via /r/TheSilphRoad http://ift.tt/2f53WuL
