Blue-capped Ifrita

The blue-capped ifrit is a species of small passerine bird in the monotypic family Ifritidae, native to the montane rainforests of New Guinea. These birds are insectivorous and are notable for their distinctive blue crown and presence of batrachotoxin, a potent neurotoxin, in their feathers and skin. This chemical defense is believed to come from their diet, particularly Choresine beetles. Blue-capped ifrits are non-aggressive and typically found in small groups within high altitude forest habitats. Although they are currently listed as of least concern by the IUCN, their population is slowly declining due to habitat disturbance and limited conservation measures.
