Yi Qi is generally depicted as having half-bird half-bat wings: feathers covering the arms and the brachiopatagium being devoid of feathers, naked and leathery.

However, the propatagium in birds isn't covered a naked bat like structure but also covered in feathers. Therefore, isn't it far more likely that the brachiopatagium in Yi Qi is also covered in feathers so that it doesnt have the batwings its usually depicted with?

Sorry no one seems to know the answer to your question.
