At the first glance it´s a simple bird with bright feathers that hangs upside down. But why do those feathers have the mentioned capacity of reflecting different colors in different directions? The nest of the bird is in the shape of a circular bowl and is usually ft (4-19 m) above the ground. The materials used for building the nest include palm leaf fibers, pandanus leaves, and casuarina needles. Young blue birds-of-paradise are called hatchlings, chicks, or juveniles. Unfortunately, the blue bird-of-paradise hasn’t been studied with respect to their flying speeds.
Because the feathers have that special capacity of reflecting certain colors for certain directions, including the direction that aims for the male’s eye. It is not staring at the female, neither letting its head tilt at gravity force. It’s indeed curving its head to have his eyes in the direction of the light reflected by its feathers.
- The family is actually very varied one, but one group of species are known as ‘plume birds’.
- With regards to migration, the blue bird-of-paradise does not show any signs of doing so.
- Then we saw that we could have a a structure of eye which has evolved from an eye which was used for a function that not seeing.
- They are currently classified as Vulnerable by evaluations carried out by the IUCN in their Red List.
- And…hagfish has also its eyes covered by skin, what does not blocks the eye’s function.
- This display by males is not aimed at any particular female, but at any bird of the opposite gender that is in the vicinity.
If the display becomes successful, the female will start to build its nest made of twigs, stems, palm leaves and vines. The cup like shaped nest will now be ready for mating where the female will be laying an egg. During the breeding season, the male Blue Bird of Paradise displays their colorful and breathtaking tails to attract females. They do this while hanging upside down, showing off the black oval outline on its body. Coming back to our theme, we were thinking about pointing an intense certain wavelenght beam of light and check if it caused a lowering of blood pression.
The blue bird-of-paradise , is a beautiful, relatively large species of bird-of-paradise. It is the only species in the Paradisornis genus but was previously included in the genusParadisaea. Mostly black, this bird of paradise has a bluish-white bill, dark grey legs, and a broken white eye-ring, and bright blue wings.
The nesting and parental duties are covered only by the females; she builds her nest with stems, twigs, palm leaves, vines and other materials all by herself, usually in a flat cup-like shape. They mostly lay one egg, but two are less occasional, and the mother is very defensive of her brood. The eggs are described to be a salmon-type color, with the ends being ringed with flecks of cinnamon-rufous to tawny. A beautiful large bird with amazing plumage of blue, red, white and black. A way for discovering the role of hormones would be check if there was some one in the birds when upside down that caused lowering of pression. But this birds are indangered and so maybe the study could be taken in other animals that are also under some conditions that favor higher intracranial pressions…
So the bird of paradise can perhaps lowers it by the certain light reflected from its feathers. Depending on the angle from which the bird is being observed, the feathers reflect completely different colours. During the mating rituals, when the male hangs upside down, from the female’s point of view the feathers are yellow, but when they’re watched from the sides they reflect the colour blue.
How big is a blue bird-of-paradise?
However, it has been noticed that most males and females breed during the later half months of the year, between July and February. The nesting takes place during the winter months with the eggs laid in the spring months of April. This bird’s beautiful blue plumage is enhanced to perfection by his equally beautiful dancing in his courtship display. Even can happens that light reduces blood pression and hormones too. Light in the skin below eye could perhaps reduce the blood pression by a change in hormones levels or production of one or more.
Despite not being as colorful as the rainbow lorikeet or species of Indian peafowl, the blue bird-of-paradise is one of the most stunning birds to look at. Their striking dark colors contrasted with traces of white and red on their plumes are beautiful. Many find their courtship display to be unique and adorable. The underparts of male birds are also blackish-blue in the coloration of the plumes.

Dancing in elegance for display and fanning its beautiful plumes makes the Blue Bird of Paradise one of the most adorable large birds on the planet. These birds are one of the most beautiful large birds you can see up to this day. Though they are already vulnerable to extinction, one may still find them in certain areas in New Guinea. The Blue Bird of Paradise are slowly decreasing in number due to the rapid loss of habitat and hunting. Their colorful plumes have quite captured a lot of attention in the market, making it highly priced. And so light with a certain wavelenght pointed to subeye zone maybe causes a decrease in blood pression.
However, more recent studies have shown that the DNA evidence is enough to give this species their own genus, Paradisornis, which roughly translates to ‘paradise bird’ in Latin. Polygamy is the practice of breeding with multiple partners. When a male breeds with more than one female at the same time – it is called polygyny….

Known for their unique courtship displays, there have been plenty of photos that have created excitement on social media. However, this attention has had some harmful impacts on this species of bird. The species occurs in the eastern Central Ranges ofPapua New Guinea and, owing to ongoing habitat loss, limited range, small population size and the hunting for its highly prized plumes, it’s classified as Vulnerable. The blue bird-of-paradise is a beautiful, relatively large species of bird-of-paradise. It is the only species in the genus Paradisornis, but was previously included in the genus Paradisaea. It is often regarded as one of the most fabulous and extravagant of all birds of the world, with its glorified and fancy flank feathers present only in males and also their two long wires also only found in the males.
This bird is commonly seen in the mid montane forest that is located in the eastern part of New Guinea. It has a black head that stretches at the back and solid bright blue color for its wings and tail with split eye ring and bluish white bill. But what sets the Blue Bird of Paradise a beauty from the rest is the remarkable tail streamers that come in red and blue hues that blend into a blue violet color once it dances for display.
Second, hagfish can be an example of the kind of eye that our eyes evolved from . Beyond what was said, even lamprey, during its growing, in the larva stage, present a retina with 2 layers, no iris or crystalline, no muscle supporting eye and the eye is under the skin . Then, during metamorphosis, retina develops a 3 layer , a crystalline and an iris are formed and eye comes to the surface. First it is important to note that hagfish is almost blind, and that despite it, its eyes didn’t disappear along the time. New branches refer to groups of species which today present different characterists and which are believed evolved in a different way somewhere in the past.
Along with these is a very different bird of paradise species, one known as the Magnificent Bird . The Blue Bird-of-paradise occurs in lower montane forest, mainly at 1,400-1,800 m, but occasionally from 1,100 to 2,000 m , especially female-plumaged birds. Although displaying males usually use patches of primary forest, they have also been reported singing in the highly populous Tari valley, in areas with little remaining primary forest (B. Beehler in litt. 2012).

They typically feed alone, though females and juveniles are more likely to feed in trees in association with other birds or other species. They are shown to search high in the canopy when seeking fruits, and apparently forage at lower altitudes when in search of their animal prey. The male is also adorned with violet-blue and cinnamon-shaded flank plumes, from which emerge two long ribbon-like tail feathers. The display by hanging upside-down on a branch and spreading his feathers into a triangular shape, exposing a black oval patch surrounded by red on the breast. The oval looked like pulsating as it slowly fans its feathers and makes soft buzzing noise.
An even more interesting fact about this unique bird is that its feathers reflect the incident light in different directions and are able to generate several colors at the same time. Being omnivores, the blue bird-of-paradise is known to eat lizards, possibly skinks such as the blue-tongue skink and other animals, while also having a diet full of seeds and fruits. The litter size of this species is usually one, but in rare cases, it can go up to two.
The incubation period is around 18 days, with the mother being the sole carer for the young hatchling. Being a bird, the blue bird-of-paradise belongs to the class of Aves. The scientific name of these birds-of-paradise has two different variations. Initially, they were placed under the genus Paradisaea which currently has seven birds-of-paradise species.
