Tail is determinable by morphology: if it's made with the body vertebrae or a limb, it can be considered vertebral. Ovoraptor has nothing more that a bunch of feathers, which don't count as a proper tail.

Oviraptorids' wings aren't fully developed: they still end in hands and have no flight adaptations. And they're not completely bird-like: their tail is theropodal, and they aren't fully covered by feathers (neither in real life, as many species probably lived in desertic environments, where being covered in feathers would have been a problem due to the heat)
