This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Huma (Persian)
The Huma, is a mythical bird of Iranian legends and fables, and continuing as a common motif in Sufi and Diwan poetry. Although there are many legends of the creature, common to all is that the bird is said never to alight on the ground, and instead to live its entire life flying invisibly high above the earth.
The kingship-bestowing function of the Huma bird reappear in Indian stories of the Mughal era, in which the shadow (or the alighting) of the Huma bird on a person's head or shoulder were said to bestow (or foretell) kingship. Accordingly, the feathers decorating the turbans of kings were said to be plumage of the Huma bird.
