"Ditto Observation"

#PokemonGO: I don't know if this has come up before. I am playing a level 11 account. This morning I saw a Zubat on my tracker but it wasn't a silhouette despite not having caught or hatched one yet. When I caught it, it turned into a Ditto, something I've had once already. A few minutes ago I came across another Zubat on tracker, this time it was a silhouette. So was the original Zubat not a silhouette because it was in fact a Ditto in disguise? via /r/TheSilphRoad http://ift.tt/2mMDLAH
