Blaustirn-Ifrita

Bestimmung

The blue-capped ifrit is 16–17 cm (6.3–6.7 in) long and weighs 34-36 g (1.2–1.3 oz). Species plumage is yellowish brown with a blue-black crown atop their broad head. It is a sexually dimorphic species, with ear streak coloration being white in males and more tawny yellow in females. Ifrits tend to have more stout body shapes with broad sternums and shallow keels. Their wings are short and rounded while their legs are booted, having feathers down to their stout and clawed feet. Additionally, blue-capped ifrits have batrachotoxin within their feathers and skin.

Verbreitung und Lebensraum

Blue-capped ifrits are endemic to New Guinea and Papua New Guinea, being found nowhere else on earth and having a distribution of 388,000 km2. Ifrits inhabit montane rainforest of New Guinea, living in altitude ranges of 1,000–4,000 meters (3,280–13,123 feet) above sea level. Typically, they are found at altitudes of 1,500 meters (4,921 feet) or above.

Zugverhalten

Resident species

Verhalten

As birds with weak flight abilities, blue-capped ifrits build nests about 1–3 meters (3–10 feet) above the ground in the branches of denser rainforest vegetation. These nests are made of plant fibers with some feathers. The parents tend to camouflage the outside of the nest with moss and liverworts. Ifrits lay small clutches with a typical nest containing only a single offspring. The nest camouflage, toxin excretion, and small clutch sizes may have derived from historically high rates of depredation and nest parasitism.

Schutzstatus

Ifrits are of least concern because they have a large range. Ifrits seem to have a stable population and are thought to have quite a large population size. Part of their range lies within conservation sites.
