Most paradise birds spread light through penalties, he says

Presented as the real wonders of nature, Birds of Paradise (Paradisaeidae) is a striking group worldwide For bright and colorful feathers. These birds, mainly in the new Guinea, perform mating rituals in which they spread light during complex choreography.

Now a team of scientists from the American Museum of Natural History (Amnh) and the University of Nebraska-Lincoln found yes in the USA: 37 of the 45 Paradise Bird species have bioflorescence. In other words, they absorb light at a wavelength and often redesign at a different wavelength in blue, green or red tones.

The study, published in the Royal Society Open Science magazine, explains how some feathers or other body parts of these birds absorb ultraviolet light (UV) and spread at lower frequencies. The authors in the article, “Biofluorescent wavelengths are green and yellow-green.” Says.

Examining the light emitted by the birds of paradise

Based on amnh samples collected since 1800, the study shows that the characteristic brightness of the analyzed hairs is due to the resection of UV light. “At least, this will make bioflorescent areas brighter: A yellow feather can be green, a white feather may be brighter and light headlight green. D Rene Martin.

Only 37 bioflorescent species found, representing 14 of the 17 sexuals. Lycocorax, Manukod And Fonigamus They do not have a mild production phenomenon. To test this manifestation, the authors placed their men and women in a dark room in a blue light and recorded the wavelengths and intensity of the spread.

The results showed that 21 species showed that they were fluorescent in body penalties and facial barbarians, while the phenomenon of 16 species revealed internally in the mouth and throat. In addition, all of the 36 species and probably 37 exhibited biofloreshanes in different parts of the body, such as chest and abdomen, and some kind of eye band on the edge of the head.

Bioflorescence phenomenon in fish and birds

In recent years, the phenomenon of bioflorescence has been examined by the curator of Amn Curator John Sparks, an ichthiologist and co -worker of the current study. Mainly examining a special photo configuration with fish, UV and blue lights, the museum team caught a biofloreshane in species such as sharks, turtles and corals.

About ten years ago, he worked jointly with ornithologists to analyze the phenomenon of light production in birds. “Although there are more than 10,000 poultry types, with many studies documenting bright feathers, mating exhibitions and excellent visions, very few, very few have explored the existence of bioflorescence,” Sparks said. Says.

Although multi -colored and bright mating shows were known for their stages, construction birds and the little Malurus of Australia and the new Guinea did not show shine in their bodies. But, Sparks managed to define a bright green yellow fluorescent in some birdsHe motivated this work.

What is Bioflorescent for Birds?

According to the authors, the regiment of the men of biofloresan species will be strengthened by the phenomenon. For example, they talk about the men of Lophorin species (known as the perfect paradise bird) who opened their mouths to women during their mating performances.

“Poultry animals men are usually close to these points, completely near black feathers [ou] Darkness, so the additional effect of bioflorescence can help To make these signal areas even bright when used during views“Martin adds in a statement.

However, the phenomenon seems to play a different role for women. According to the study, location and biofloresan feather molds show that there is a possible camouflage function to be mixed with the environment. Even in a group examined as birds of paradise, Martins points out that there is a place for bir new information about vision, behavior and morphology of birds.
