In Philippine mythology, the Tigmamanukan was believed by the Tagalog people to be an omen or augural bird. Although the behaviors of numerous birds and lizards were said to be omens, particular attention was paid to the tigmamanukan. Before Christianisation, the Tagalogs believed that the tigmamanukan was sent by Bathala to give hints to mankind whether they needed to proceed on a journey or not. In some Philippine creation myths, the tigmamanukan bird was sent by Bathala to crack open the primordial bamboo whence the first man and woman came out.
