Resident species.
The skin and feathers contain powerful neurotoxic alkaloids of the batrachotoxin group (also secreted by the Colombian poison dart frogs, genus Phyllobates). It is believed that these serve the birds as a chemical defence, either against ectoparasites or against visually guided predators such as snakes, raptors or humans. (Dumbacher, et al., 1992) The birds probably do not produce batrachotoxin themselves. It is most likely that the toxins come from the Choresine genus of beetles, part of the bird's diet. (Dumbacher, et al., 2004)
