Abstract

Early Polynesians settlers were the first to introduce pigs to the Hawaiian Islands. Later Captain Cook brought European pigs during his first voyage to Hawai'i. Many other importations have followed. Animals from these introductions became feral and dispersed throughout the islands. Free-ranging pigs are now considered pests with negative impacts on some native biota. Several methods to control the ecological damage attributed to pigs have been adopted, such as fencing, hunting, live trapping and poisoning. However, the absence of behavioral knowledge in current control programs has resulted in inefficient management of this species. Therefore, the feral pig problem continues, and what before was almost strictly an agricultural and conservation concern has now become an urban problem as well. The aim of this study is to describe the state of knowledge on feral pig behavior in the Hawaiian Islands, introducing potential management approaches derived from the principles of behavioral ecology. Considering behavioral aspects of feral pig ecology, such as cognition and communication could help improve capture techniques, keep feral pigs away from urban areas and begin to resolve human-wildlife conflicts.
