They have bright blue wings and plumes with the overall appearance of the bird, including the head and the nape, being glossy black. Female birds of this species do not have this carmine red plumage on their head. The forest is the favoured residence for the The Blue Bird-of-paradise. The elevational zone is under pressure from clearance for subsistence gardens by the increasing human population. The second major threat is hunting of adult males for their pectoral and tail feathers . Due to ongoing habitat loss, this bird has a decreasing limited range with a small population size.
- The oval looked like pulsating as it slowly fans its feathers and makes soft buzzing noise.
- Lamprey, an interesting animal who lives in water, and, lacking of a proper mouth, sucks its food intead of bitting it, is a jawless, vertebrate who caught the attention of scientists.
- The eye-ring is whitish-silver and provides a great contrast to the dark colors of the bird.
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).

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.
Illustration of two male and a female, most likely an early conception of the species. The Blue Bird-of-paradise is classified as Vulnerable , considered to be facing a high risk of extinction in the wild.

Then we saw that when bird faced itself, light was reflected into its eyes, but not only. 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. Coming back to our Rudolphi bird, we have tried to demonstrate that if in humans light is probably related with lowering/capacity to endure intracranial blood pressure, it could also happen on it. And thinking about it, the effect must be achieved by a certain wavelenght. Because it´s a certain wavelenght that is reflected by the feathers to the male, and not a random one.
Where does a blue bird-of-paradise live?
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….
They are also under threat from hunting for their highly prized plumes, thus blue birds-of-paradise are classed as Vulnerable on the IUCN Red List. The Blue Bird of Paradise, just like the other birds have differences in their looks depending on their sex. The male are more colorful with blue violet and sometimes cinnamon colored plumes with two ribbon like feathers. The females are a little bit duller in color, and are often chestnut brown. During the mating dance the bird hangs from a branch upside down. The black oval with red margin at the centre of his chest is rhythmically enlarged and contracted.
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.
During the breeding season, the male puts on a breathtaking display while hanging upside down from a branch pulsating the black oval with a rid margin on his chest, rhythmically enlarging and contracting its size. At the same time fanning out his violet-blue plumes, continuously making a soft, insect-like buzzing noise, mixed with chittering or chattering. If he is successful in his efforts the female goes on to build a nest from stems, twigs, palm leaves, and vines in a flat cup-like shape.
We already know that the male blue bird-of-paradise is primarily solitary by nature. However, during mating, the male bird is not monogamous and has a reputation of being very promiscuous. The breeding season starts when the males start to display their unique courtship ritual. Perched upside down on a thin branch of a trees, male birds expand and contract their chest fanning out their violet-blue plumes and feathers. This display by males is not aimed at any particular female, but at any bird of the opposite gender that is in the vicinity.
