The Wakwak arises from Philippine popular stories as a night predator whose name is derived from the distinctive wak-wak sound attributed to it while flying. Sources present it in two overlapping registers: as a supernatural, vampiric bird that physically preys on humans at night and as an ordinary nocturnal bird associated with witches. Ethnographic notes in the sources indicate the belief functions as a local explanation for frightening nocturnal sounds and as part of a broader set of night-dwelling monsters (manananggal, ekek, aswang). Over time the tale’s prominence has declined in some areas and now often appears in storytelling as a device to frighten children.
Traditional descriptions in the available sources are terse and variable but consistently characterize the Wakwak as bird-like and predatory. Common elements recorded are long, sharp talons and wings sometimes compared to bat wings; wings are also described in some accounts as having sharp edges. Derivative modern sources (game or fiction summaries) add details such as long legs with curved talons, bone-like ridges on wing edges, or a blood-stained beak, but these specific embellishments are identified in the record as later, non-ethnographic elaborations rather than core traditional descriptions.
Sources describe the Wakwak as a nocturnal hunter that snatches humans at night, using claws or talons to slash victims, remove hearts, and sometimes tear bodies apart. It is grouped with other Philippine nocturnal predators (manananggal, ekek, aswang) and is sometimes described as a form of vampire. An important behavioral trait in the lore is the wak-wak sound: folk belief holds that the call is heard while it hunts and that the sound paradoxically grows softer as the creature draws nearer, so a faint wak-wak is taken as indicating imminent danger. Some accounts connect sightings or sounds to witches, implying human practitioners may be linked with or control such birds in certain local interpretations.
Manananggal
A terrifying Philippine vampire who severs its own upper body from its lower half at night, sprouting bat wings to fly out and feast on sleeping pregnant women's fetuses.
Ekek
A nocturnal birdlike human predator from Philippine folklore, the Ekek (or Ek Ek) is a winged creature said to hunt at night for flesh and blood, particularly targeting sleeping pregnant women and draining fetuses with a long proboscis.
Aswang
The most feared supernatural being in Philippine folklore — a shape-shifting monster that appears human by day but transforms at night to prey on pregnant women and children.
Aguingay
Aguingay (also Agingay) is a legendary woman from the Bulusan epic of Sorsogon, Philippines. Presented as a mortal of exceptional beauty and tragic fate, her life and death are etiologically linked to local landscape features (Mt. Bulusan and two lakes) and commemorated in an annual festival.
Alan
A class of non‑human spirit-beings in Tinguian (Philipine) folklore associated with reproductive wastes and springs; said to transform discarded menstrual blood, afterbirth, or miscarried tissue into human children whom they rear, and to dwell in fine houses near springs. Key described features include wings and backward-pointing fingers and toes.
Amalanhig
Amalanhig are Visayan undead beings in Philippine folk belief, described as aswang who failed to transfer their monstrosity or power before death and who rise from graves to attack living humans. Accounts portray them as externally human in appearance with enlarged upper canines and as predators that bite, feed with a pointed tongue in some tellings, or — in an alternative variant — tickle victims to death.
Angalo
Angalo is a primordial culture-hero and giant in Ilocano mythology credited with shaping the landscape of Luzon and explaining natural phenomena; narratives present him as the first man and an ancestral figure whose bodily acts produced mountains, valleys, seas, and celestial features.
Anggitay
A Philippine folkloric female equid–human hybrid often described with the upper body of a woman and the lower body of a horse. Frequently compared to the Greek centauride and sometimes presented as a female counterpart to the tikbalang; traditionally associated with an attraction to gemstones and jewelry and with a local homeland in Santo Tomas, Batangas in some accounts.
Anito
Anito is a category of non‑human and post‑human spiritual beings in indigenous Philippine animistic worldviews, encompassing ancestor spirits, nature spirits/local deities, and sometimes carved effigies (taotao) that house or represent those spirits. They mediate relations between the living and the unseen world, functioning as household guardians, owners of places, intercessors, or occasional agents of harm when offended.
Aswang
The most feared supernatural being in Philippine folklore — a shape-shifting monster that appears human by day but transforms at night to prey on pregnant women and children.
Bakla
Bakla is a Philippine social and gender category—commonly an assigned‑male‑at‑birth person who adopts a feminine gender expression and is often treated as a third gender. Historically some bakla served as indigenous ritual specialists (babaylan, katalonan), but the term itself denotes a social identity, not a supernatural being.
Bakunawa
A dragon- or serpent-like mythic being from Philippine tradition associated with the moon and eclipses; its actions explain lunar eclipses and some natural phenomena and were integrated into ritual practice and calendrical knowledge.
Bal-Bal
A Philippine folkloric undead/monster that steals corpses from funerals and graves and feeds on them, noted for keen scent for dead bodies, sharp claws and teeth, foul breath, and reportedly leaving a banana‑tree trunk in the coffin as a substitute for the stolen corpse.
Bathalà
In pre‑colonial Tagalog religion Bathalà (also Maykapál) functions as the transcendent supreme creator-preserver — the originator and ruler of the universe. The lexeme also served as an honorific applied to lesser tutelary spirits and portentous phenomena, and was later syncretized with the Christian Dios after Spanish contact.
Batibat
The Batibat is a vengeful, tree-dwelling female spirit in Philippine (Ilocano and Tagalog) folklore associated with causing suffocative sleep afflictions, nightmares, and sleep paralysis when trees that house it are felled and used near human sleeping spaces.
