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. Despite their toxicity, blue-capped ifrits are non-aggressive and typically found in small groups within high altitude forest habitats. Although they are currently listed as Least concern by the IUCN, their population is slowly declining due to habitat disturbance and limited conservation measures.
Region
New Guinea Highlands
Typical Environment
Found across the central cordillera and outlying ranges of New Guinea, including mossy montane and subalpine forests. It prefers dense, humid interiors with abundant epiphytes, moss-covered trunks, and fallen logs. Birds forage from understory to mid-canopy, often along shaded ridges and steep gullies. It is less common at forest edge and rarely descends into lowlands.
Altitude Range
1,500–3,800 m

Ease of Keeping
Beginner friendly: 1/5
The blue-capped ifrit is one of the few known poisonous birds; its skin and feathers can contain batrachotoxins, likely acquired from a diet that includes Choresine beetles. It inhabits cool, mossy montane forests of New Guinea and forages methodically on trunks and branches. Despite its toxicity, it is shy and non-aggressive, and poses little risk unless handled. Its distinctive blue crown and dark facial mask make it uniquely identifiable in its range.

Temperament
shy and deliberate
Flight Pattern
short rapid wingbeats with brief glides
Social Behavior
Usually solitary or in pairs, occasionally joining mixed-species foraging flocks. Nests are placed low to mid-level in dense vegetation or on banks, constructed from moss and plant fibers. Clutches are small and parental care is shared.
Migratory Pattern
Resident
Song Description
Song is a soft series of thin whistles and high, sibilant notes delivered from concealed perches. Calls include sharp tseet and soft trills, often given while foraging.
Plumage
Olive-brown upperparts with warm brown wings and tail; underparts buff to yellowish with paler throat. Crown and nape show a distinctive blue sheen, contrasting with a darker facial mask. Feathers often appear slightly fluffy in the cool, damp montane environment.
Diet
Primarily small insects and other arthropods gleaned from bark, moss, and epiphytes. It probes crevices and flips leaf litter on logs to find beetles, ants, and larvae. Consumption of certain beetles (notably Choresine) is thought to provide batrachotoxins that accumulate in feathers and skin.
Preferred Environment
Feeds in cool, shaded, mossy forest interiors, from the understory to mid-canopy. Often forages along trunks, branches, and fallen logs, and may follow mixed flocks to exploit disturbed prey.
