Manaul

Manaul is a bird in Philippine stories, but tellers give it different roles. In the Panay myth it is the sacred bird of the first people. The word is also a local name for the Philippine eagle and for the white-bellied sea eagle, so some stories may speak of a real bird.

Wikipedia lists at least four tales. In one Tagalog tale, the god Bathala sends an omen bird called Manaul. It pecks open a bamboo and the first man and woman, Malakas and Maganda, step out. Some sources give the credit to Amihan instead. Among the Mangyan, Manaul is a proud king who rebels against the gods. The god Kaptan throws rocks at him, the rocks miss, and they become islands. A Bisayan tale also makes Manaul a king whose war between earth and sky ends with rocks in the sea that turn into islands. A bird named Manaul also appears in the Code of Kalantiaw, where killing it is punished by death. That code is a 1913 hoax, so this detail is not old law.

The Wikipedia article uses a single source, and some claims lack citations. Treat these tales as retellings.
