Well if you go back a few episodes when Ruby first went into the forest, she hits a bird that was clearly bigger then she was. Combine that with the fact that the Emerald Forest is full of Grimm and that a large Grimm bird is in the credits, and you have one seriously dangerous monster on your hands.
