I just checked now, and over two thirds of the images tagged with “princess skystar” have her as a sea pony, or otherwise not a hippogriff.
(A round 70%, to be precise.)
Also, what @Background Pony #A0C1 said. Character tags don’t imply species tags, partly because of situations like Skystar’s, but mostly because there’s a lot of humanized and species swap art on this site.
