Nestlings hatch naked and with their eyes closed and stay on the nest until fledging . Victoria’s riflebird nestlings are brooded for the first six to seven days until they open their eyes and can thermoregulate and they achieve pin-break on their primary and secondary feathers by day twelve. Nestlings are fed two to three times an hour, with the female away from the nest for longer with two nestlings. Victoria’s riflebird fledglings become independent from their parent after 74 days, while this period is unknown for the other species. It is similar in appearance to the other riflebird species, with males having similar iridescent blue-green patches and females appearing gray-brown with barred-patterned underparts.
The male is a velvet black and green bird-of-paradise with black flank plumes, black curved bill, yellow mouth, blackish feet and dark brown iris. It has an iridescent greenish blue on its crown, throat, breast shield and central tail feathers. New Guinea’s dense tropical montane forests are home to 12 of 14 tree kangaroo species. Over the past couple of decades, conservationists have leveraged these charismatic, intelligent marsupials to spearhead community development, conservation efforts, and the establishment of protected areas. In Papua New Guinea, the Torricelli mountain range is home to three species of tree kangaroo, including the critically endangered tenkile. This mountain range sits in the crosshairs of a road project threatening to encroach upon the region; however, the government is in the process of reviewing a draft proposal to have it officially declared a protected area.
More recently, they have occasionally been considered pests for damaging cultivated fruit. While riflebirds have been shown to use habitat adjacent to rainforest, their reliance on rainforest leaves them vulnerable to forest clearing. The four species of riflebird are classified as being of “Least Concern” according to the IUCN Red List of Threatened Species.

Male Riflebirds have been known to live up to 15 years in the wild. The Growling riflebird , also known as the eastern riflebird is a species medium-sized bird-of-paradise. The common name “riflebird” comes from the likeness of their black velvety plumage to the uniform of the British Army Rifle Brigade. Spanning over 4,000 kilometers and being built over the course of decades, the Trans-Papua Highway cuts across the entire length of Indonesian New Guinea’s two provinces, including 7 key protected areas. While the project is nearly complete, experts warn it will cost billions annually to maintain, and threaten to open up untouched rainforest to palm oil expansion contributing an additional 4.5 million hectares of deforestation by 2036. The Tanah Merah project sits in the heart of New Guinea covering 2,800 square kilometers .
- They detail the successes and challenges of working for nearly two decades in PNG to conserve these intelligent marsupials and the lands they inhabit.
- This tour is a comprehensive birding exploration of Papua New Guinea, the eastern half of the island of New Guinea.
- Over the past couple of decades, conservationists have leveraged these charismatic, intelligent marsupials to spearhead community development, conservation efforts, and the establishment of protected areas.
- Formerly a member of the genus Ptiloris, it has since been moved to the genus Lophorina alongside other riflebird species.
Sample the highlights of birding in Papua New Guinea, the eastern half of the island of New Guinea. Oviparous animals are female animals that lay their eggs, with little or no other embryonic development within the mother.

He also shares an update on the critically endangered Tapanuli orangutan, whose land is threatened by a controversial hydroelectric project in North Sumatra, which has also claimed the lives of 16 workers in less than two years. A podcast about the world’s unique places and species – from areas of amazing natural heritage to environmental challenges and conservation solutions – hear inspiring conversations with experts, scientists, authors, and activists on Mongabay Explores.

The genus Ptiloris consists of four allopatric species of birds in the Paradisaeidae family. These birds of paradise are commonly known as riflebirds, so named for the likeness of their black velvety plumage to the uniform of the Rifle Brigade. Alternatively, the bird’s cry is similar to a rifle being fired and hitting its target but a call like this is not commonly reported . They are distributed in the rainforests of New Guinea and Eastern Australia. During breeding season, males perform solitary displays for females, which involves moving rapidly from side to side with the head tilted back, showing off the neck plumage. The four riflebird species are separated geographically, an easy characteristic for field identification.

The central tail feathers are shortened, giving an appearance of blue over black along the tail. It has been suggested that some of the male’s feathers are super black feathers. These feathers have been modified so that their barbules structurally absorb light, unlike normal black feathers, which emphasizes a darker appearance. These specialized feathers are found adjacent to brightly colored patches, suggesting that they help create optical illusions during courtship displays by exaggerating the bright colors they are juxtaposed to.

We also speak with Nora Devoe, research program manager for a special project focused on the galip nut at the Australian Centre for International Agricultural Research . This project has been funding more than a decade of research seeking to understand the viability and potential of the galip nut to drive the canarium industry in PNG and foster new markets for entrepreneurs and locals like Dorothy to sell the crop.
Formerly a member of the genus Ptiloris, it has since been moved to the genus Lophorina alongside other riflebird species. It is found in subtropical, temperate rainforests in eastern Australia. The species is sexually dimorphic; the male is black with iridescent blue-green patches, while the female is gray-brown and white. Female riflebirds are solely responsible for nest construction, incubation and feeding nestlings.
They then open their bills, showing a bright yellow mouth, still while moving from side to side. Finally, the males will flatten out their wings, creating a flat surface that looks like a blue screaming mouth on a black background. If the female is happy with this display, she will reward him with multiple matings; the female then leaves to build her nest, while the male tries to woo more females.

Breeding occurs from August to February, during the spring to summer months in Australia. Like other birds of paradise, the paradise riflebird is polyginous. The male paradise riflebird performs a solitary display to females from perches of low-hanging, exposed canopy.
By 2025 the global, edible nut industry will be worth an estimated $2 billion. In Papua New Guinea , the traditional and plentiful staple, the galip nut , holds promise of tapping into that demand. Its relative ease of access for smallholder (non-commercial) farms means a new source of income for thousands of farmers across PNG. For this episode of Mongabay Explores, we interview Bustar Maitar, founder and CEO of the EcoNusa Foundation, and Edwin Scholes, head of the Birds-of-Paradise Project at the Cornell Lab of Ornithology. Animals that do not make seasonal movements and stay in their native home ranges all year round are called not migrants or residents.
