Now you're getting somewhere. What I was thinking, actually, was that it's basically one "New Region" with spread out zones within it.
The Horse and Raptor seem obviously indicating Kul'tiras and Zandalar. The Parrot to me indicated Plunder Isle also shows up.
The ghost horse is the real mystery here. What does it mean? I doubt it's associated with the Horse/Raptor as those seem obvious to be an Alliance Mount and Horde Mount.
