I have to concur with Grahamburglar. I've never heard of a banshee being a shapeshifter either. And if there are stories of it out there it's hardly a primary enough feature to refer to them as such, especially as the show hasn't introduced that aspect to their mythos.

Also, Wendigo are really shape shifters either.

''The Wendigo is a creature appearing in the mythology of the Algonquian people. Descriptions of the Wendigo vary across culture, but they are generally described as a large alien-like canine beast. They are malevolent and cannibalistic creatures. Wendigos are strongly associated with the winter, the north, and coldness. Human beings will transform into Wendigos if they perform cannibalism. The person will become possessed by the demonic spirit of the beast, usually in a dream. Once transformed, the individual will become violent and obsessed with eating human flesh. These monsters are the embodiments of gluttony, greed, and excess. They are never satisfied with killing and consuming one person. Wendigos are constantly searching for new victims. They have been classified as giants and upon transformation the human will grow considerably in size. They populate rural and highly forested, mountainous regions. Recently the Wendigo has become a horror entity, much like the vampire, werewolf, or zombie.''- https://m.youtube.com/watch?v=x78PnPd-V-A

Everything I've read makes it seem as if they transform into this creature, and not back out of it.
