The Iban are an ethnolinguistic group that now live primarily in Sarawak, but are believed to have migrated from the Upper Kapuas region of Kalimantan within the past few hundred years. In the nineteenth century they were notorious for headhunting and resistance to colonial control. The principal Iban god was Sengalang Bulong, who manifested himself in the form of a Brahminy Kite.
