This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Byangoma (Bengali)
Byangoma are legendary human-faced birds of Bengali folklore, appearing notably in the fairytales of Thakurmar Jhuli, where they are portrayed as wise, fortune-telling birds that help the deserving. A magical bird found in West Bengal and Bangladesh, these creatures are born and mature completely blind, using some innate Seer ability in order to sense where they’re going and any obstacles in their path.
Every person experiences this fortune telling differently. Some claim to hear a voice, others receive visions. The most common experience is to hear the birds song, and suddenly have an intuition about a future event.
