It's not a bird, but a ty
It's not a bird, but a type of these real-life animals with long-arms and man-eating tendencies was known as the Xiao. One of these animals accidentally kills his brother by sealing up a cave, having mistaken the blood seeping out of it for his sibling's. Prior to their transformation into these animals, two gods placed their younger half-brothers on anthills and wore loincloths; post- transformation, those relatives of the Mayan Hero Twins become patrons of the arts. Another of these animals mistook the sun for a mango and once brought back a whole mountain because an herb grew on it. That son of Vayu extinguishes his flaming tail on the sea around Lanka. For 10 points, give this animal form of Rama's ally Hanuman.
