Nestlings have been reported as being fed crickets, grasshoppers, spiders, cockroaches, centipedes, cicadas, woodlice, beetles and insect larvae. Males may take proportionally more easily obtained and energy-rich fruit to allow them to display for longer. The genus Ptiloris consists of four allopatric species of birds in the family Paradisaeidae. 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.
The Certificate of Authenticity which arrives with every painting provides an assurance and verifies the authenticity of the hand painted fine art reproduction you purchased. Each oil painting is created by hand using only the finest canvas and oil paints available. The four riflebird species are separated geographically, an easy characteristic for field identification. Both species are largely absent from the highlands of New Guinea.

The Victoria’s riflebird is evaluated as vulnerable on the IUCN Red List of Threatened Species. The female is attracted to the male’s display post by his raspy ‘yaars’ call, which becomes softer and more tuneful during the display.
- Victoria’s riflebirds are found on the Atherton Tablelands of Queensland, Australia, from just south of Cooktown to just south of Townsville.
- 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 .
- During the breeding season, male Victoria’s riflebirds have been reported to have home ranges of 0.6 to 2.8 ha, containing up to 5 display posts.
- While riflebirds have been shown to use habitat adjacent to rainforest, their reliance on rainforest leaves them vulnerable to forest clearing.
During the breeding season, male Victoria’s riflebirds have been reported to have home ranges of 0.6 to 2.8 ha, containing up to 5 display posts. Males can use the same display sites for many successive years. Male riflebirds appear to rigidly follow a progression of vocalisations, postures and movements when displaying to females. The first stage is to call from the display perch and expose their yellow gape to attract attention. Male paradise and Victoria’s riflebirds make a sound like “yass,” male magnificent riflebirds produce a series of low whistles, and male growling riflebirds make a growling sound .

If you would like to ensure that no cropping or adjusting is required, then we recommend that you order the painting in a size that still maintains the original aspect ratio. Check the box marked ‘Maintain original proportions’ in order to always keep the same aspect ratio as the original painting. Input your desired width or height and the other dimension will automatically adjust in keeping with the original proportions.
Our most senior artists, those who have at least 25 years experience, carefully examine each and every painting that comes out of our studio. No order is shipped before it meets our standards, which are the highest in the industry. When ordering the painting framed – allow additional 5-7 days for delivery. Ordered without a frame, it will be delivered in protective tube within business days.
At this stage, male magnificent and growling riflebirds may start hopping sideways along the display branch. A female riflebird signals her receptiveness by briefly fluttering her wings and the male hops onto her back before copulation. Immature males may attempt to display during the breeding season as well but they appear clumsy and uncoordinated, like they need to learn to display correctly. Riflebirds are stocky medium-sized passerines with a small head and a characteristic long slender decurved bill.
Distribution and habitat
The Reproduction will be hand painted by one of our talented artist. Riflebirds were one of the species I knew about even before we thought of going to Australia. I knew them from seeing videos of their incredible mating displays, and was just hoping to catch a glimpse of one on our trip. I knew they were around the tropical northeastern part of Australia where we stayed for 8 days late in the trip, so thought I had a chance to see one. Superstock offers millions of photos, videos, and stock assets to creatives around the world.
Victoria’s riflebird has been reported to feed on 19 species of fruiting trees and vines. Female riflebirds are solely responsible for nest construction, incubation and feeding nestlings. The nests of Victoria’s riflebirds may be parasitised by the Pacific koel . Victoria’s riflebird usually lays two eggs each weighing approximately 10g on consecutive days, incubated for 18 to 19 days and nestlings brooded and fed for 13 to 15 days.

He curves his rounded wings above his body and tilts his head back to expose his chin and throat to the light, and then moves from side to side in a fashion that looks almost mechanical. The Victoria’s riflebird was discovered by John Macgillivray for John Gould in 1848 and is named after Queen Victoria of the United Kingdom. The common name “riflebird” comes from the likeness of their black velvety plumage to the uniform of the British Army Rifle Brigade.

Victoria’s Riflebird (Ptiloris victoriae)
Like most other birds of paradise, riflebirds are polygynous, with promiscuous males displaying to and mating with several different females. Birds of paradise are well known for their elaborate courtship displays. Unlike some however, male riflebirds display alone and have been seen during the breeding season to territorially defend displaying sites. Otherwise, male riflebirds are generally tolerant of other riflebirds. The breeding season for riflebirds is generally considered to be from June to February.
Adults have short broad wings with rounded tips, short tails and long sturdy legs with long powerful toes and hooked claws. Like many of the birds of paradise, adult riflebirds are sexually dimorphic, with adult males being entirely velvety black and females being mostly shades of brown. Adult males are larger in P. magnifica (31 cm long, 160g; P. intercedens is similarly sized), smaller in P. paradisea , and smallest in P. victoriae . Dispersion, movements and diet of male Victoria’s Riflebirds, Ptiloris victoriae, were studied in a vegetation mosaic dominated by rainforest and regrowth. Habitat use within the mosaic was assessed by a series of point surveys along transects through each habitat. The home ranges of eight males with display areas on the study site were mapped by observation of marked males and by following unmarked males as they moved between display posts or foraged.
If you’re considering not framing your painting at all, you may opt for a Gallery Wrap. The term Gallery Wrap refers to the way the canvas is stretched, which is by wrapping it around thick stretcher bars, about 1.5 inch thick, with the canvas being secured to the back rather than the sides of those bars. You may choose to purchase your painting framed, in which case, it will arrive “ready to hang”.
