Cinnyris idenburgi
Cinnyris idenburgi, commonly known as the Mamberamo Sunbird, is a diminutive and dazzling passerine endemic to the remote montane forests of New Guinea. Measuring approximately 9-11 cm in length and weighing a mere 5-7 grams, males are instantly recognizable by their brilliant, iridescent metallic green head and upperparts, contrasting with a deep, velvety black breast band often bordered with narrow blue or violet bands, and a bright yellow to orange belly. Females are typically much plainer...
Primarily inhabits tropical and subtropical moist montane forests, forest edges, and regenerating secondary growth, typically found at elevations between 800 and 1,800 meters.
Feeds predominantly on nectar from a variety of flowering plants, supplemented by small insects and spiders gleaned from foliage and bark.
Mamberamo Sunbirds are highly active, diurnal birds, constantly flitting among flowering vegetation in search of sustenance. Foraging involves acrobatic hovering, much like hummingbirds, to extract nectar from flowers, or perching delicately to probe with their specialized bills. They also glean ...
The Mamberamo Sunbird is strictly endemic to the island of New Guinea, with its distribution confined to specific montane regions within the Indonesian province of Papua. Its primary breeding and year-round range is centered around the Mamberamo River basin, extending into adjacent montane areas ...
Least Concern
- The Mamberamo Sunbird's iridescent plumage is created by microscopic feather structures that refract light, rather than pigments. - Despite their superficial resemblance, sunbirds are not closely related to hummingbirds; their similar feeding styles are an example of convergent evolution. - The...
