Pitohuis are brightly coloured, omnivorous birds. The skin and feathers of some pitohuis, especially the Variable and Hooded Pitohuis, contain powerful neurotoxic alkaloids of the batrachotoxin group (also secreted by the Colombian poison dart frogs, genus Phyllobates). These are believed to serve the birds as a chemical defense, either against ectoparasites or against visually guided predators such as snakes, raptors or humans.
