There are no known blue pigments in bird feathers or skin. These blues are called structural colors because they are created by the way light interacts with surfaces and spaces on a microscopic scale. Sexual dimorphism, strong physical distinctions between the sexes, is not found in all birds of paradise. All five birds in the Manucodia genus are monomorphic, with almost no plumage variation between the sexes.
Terrestrial animals are animals that live predominantly or entirely on land (e.g., cats, ants, snails), as compared with aquatic animals, which liv… Please register for an account to take part in the discussions in the forum, post your pictures in the gallery and more.

Goldie’s bird-of-paradise is a bird of the family Paradisaeidae, and inhabits a pair of islands off the coast of Papua New Guinea in the south Pacific Ocean. This is a part of the Wikipedia article used under the Creative Commons Attribution-Sharealike 3.0 Unported License (CC-BY-SA). The Goldie’s bird-of-paradise is a species of bird-of-paradise.
Their showy features are a delight to behold, but they would also make them an easy target for hungry cats and other predatory mammals — if there were any around. The absence of such predators is precisely what allowed these otherwise impractical species to evolve. Black and white are more than just the absence or presence of full-spectrum light. Each is specific, and the two are often paired to dramatic effect. Click through the gallery to see some examples of this paring. Images of Wahnes’s Parotia show hue changing rapidly across a wide spectrum, suggesting that their breast feathers use the same mechanism.
Males prefer courting females atop vertical poles or branches. More than 20 years ago, wildlife photographer Tim Laman saw his first birds of paradise, the Standardwing and the Red Bird of Paradise, while traveling in Indonesia. He started imagining a project to photograph every species of these birds in theirnatural habitatsof New Guinea and parts of Australia. Not unlike photo paper or wall paint, feathers come in a range from matte to semi-gloss and glossy.
You can tell that this is a structural color, not a pigment, since the color disappears when seen from the side. The iridescent effect can be seen best in a series of images. In the Magnificent Riflebird, the hue shifts as this male twists his head.
Birds also can discern smaller differences between colors than people can. That’s because they have oil-droplet filters that sharpen the sensitivity of each kind of cone cell. Most birds have four kinds of color receptors in their eyes. The extra kind allows them to see into the ultraviolet spectrum, where they can sense entire visual signals that are imperceptible to humans.

The face of the Long-tailed Paradigalla has skin patches of non-iridescent yellow, blue, and red. If each color is produced the usual way, this is a combination of three different mechanisms stacked into one spot. Yellow is usually a carotenoid pigment; blue skin is usually structural; and most red in skin is due to blood exposed by capillaries near the skin. But each of these colors can be made by other mechanisms and, in the birds-of-paradise, unusual is par for the course.
They may not be the most aerodynamically efficient wings, but they are beautiful to look at. Black is a result of melanin pigment, but some blacks are more pure and flat than others. This is analogous to the way normal black fabric and black velvet may use the same dye but to noticeably different effects. The Blue Bird-of-Paradise is a good example of when females look more or less like drab versions of the males.
Females are able to raise hatchlings alone, freeing up the male to court other females with his magnificent and much-needed plumage. Ribbon-tailed Astrapia females don’t have the intensely iridescent colors of the males, but they do have colored feathers of the head and neck. Wilson’s Birds-of-Paradise have the most unusual females. They are camouflaged everywhere they have feathers, but they have the male’s blue head and legs. This hints at an underlying difference in basis for color in plumage and skin.
This piece of artwork was inspired by an article I read about the Goldie’s Bird Of Paradise and how close to extinction it is. Please note that the appearance of colors varies on all monitors, and may look slightly different than the print. This print is adapted from a vintage illustration of the Goldie’s Bird of Paradise.

- Carola Parotia , Superb bird of paradise , and Blue bird of paradise all have wildly different displays they perform for their female counterparts.
- But the hues of some parts of the body appear to change with angle, sometimes even looking black, so perhaps a structural mechanism is also involved.
Jays and bluebirds of North America are more familiar examples of this color mechanism. Recent scientific research examines these mating displays and what they can tell us about the evolutionary process. According to ornithologist Edwin Scholes III, these complex courtship performances can be broken down into a series of smaller, individual movements. These building blocks of motion are combined to form a single choreographed piece.
Habitat destruction from logging is a concern, however. There is some evidence suggesting that females prefer males who are part of more coordinated crowds. But that doesn’t mean all males in that pack will get equal access to the ladies because most females tend to choose the same male. The example at right shows a range of blacks from glossy to flat. Click through the images to see the blacks from some of the least colorful birds-of-paradise. The Splendid Astrapia has a splendid example of iridescent orange on its chest and in a line on its face.
The image has been digitally enhanced and put onto a tea-stained paper background to enhance the antique tone. Goldie’s birds-of-paradise live on two or three islands on the western edge of Papua New Guinea. After all of this, it is reasonable to ask whether birds see these colors the same way we do. While no one has specifically examined the vision of a bird-of-paradise, birds have better color vision than people in two ways. Here a Victoria’s Riflebird is showing off his inner workings while calling on a cool morning.
By simply reorganizing and modifying these steps, males can create novel performances. If females prefer those new organizations, then those displays will eventually become increasingly standard within the species. Similar to their plumage, these dance moves evolved over time, based on the subtle tastes of the females in the species. If females mate exclusively with males that perform specific types of movements, eventually that display performance will become commonplace.
The Goldie’s Bird-of-Paradise lives in forest between 300 m and at least 750 m, occasionally down to near the coast . They appear to inhabit secondary regrowth and forest edge, suggesting some tolerance of logging . As of 2016, the resumption of logging in the East Fergusson Timber Rights Purchase Areas was in its second of fifth year of logging (D. Mitchell in litt. 2016).
