Blue-capped ifrit:

The blue-capped ifrit (Ifrita kowaldi), also known as the blue-capped ifrita, is a small insectivorous bird endemic to the rainforests of New Guinea. It measures up to 16.5 cm long and has yellowish brown plumage with a blue and black crown. The male has a white streak behind its eye, while the female's is a dull yellow. It creeps on trunks and branches in search of insects.

The blue-capped ifrit is placed as the only member of the genus Ifrita, which historically has been placed in the family Cinclosomatidae or the Monarchidae. It now appears the bird is more properly placed in its own family Ifritidae. This enigmatic bird is one of only three bird genera known to have poisonous members, the others being the genus Pitohui, also from New Guinea, and the little shrikethrush (Colluricincla).

The blue-capped ifrit, like the hooded pitohui, sequesters batrachotoxin in its skin and feathers, which causes numbness and tingling to those who handle the bird. The toxin is acquired from part of its diet, specifically Choresine spp. beetles.[2]

Widespread and common throughout its large range, the blue-capped ifrit is evaluated as least concern on the IUCN Red List of Threatened Species.

Justification

This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
