Birds Birds are famous for their bright and colored brush, but it turned out to be more dazzling than previously thought.
Researchers have found that 37 out of 45 species show a vital flood – in other words, corrections from their feathers or other parts of the body absorb ultraviolet or blue light, and emitted from light at low frequencies.
“At least, it will make these biological areas brighter-may be a yellow yellow feather, and it may be a brighter and yellow feather,” said Dr. Rin Martin of the American Museum of Natural History in New. York, who was the first author of the study.
Posted in the magazine The royal society is open scienceMartin and his colleagues reported how they studied for skewers reserved for each type of aircraft, which was held in the group of flying doctors at the American Museum of Natural History.
The male and female team put out of each type under the blue light in a dark room, record the wavelengths and the severity of the light emitted. In some cases, they also shone the UV light on the leather.
The results revealed that male 21 species showed a biological mud on parts of their feathers such as their head, neck, and tail, or on fat lobes known as the face. In addition, these species in addition to 16 additional species – or likely to show – vital brilliance in their inner and throat mouth.
Females of 36 of these species showed all of them all 37, also vital brilliance. Many showed this on their chest and abdomen, or on the feathers that make up the eye tape on the side of their head.
The team said that the light emitted ranged from light blue or blue wavelengths to green and yellow.
Martin said: “It may not have an effect that makes something different, but it becomes brighter and more striking,” Martin said.
The team added that vital brilliance did not happen in species in races Lycocoraxfor Manokodia and Phonygammus. They said that this commensurate with the idea that vital brilliance was present in the joint grandfather of all birds of protrusion, but it was lost in the predecessor of these three groups.
The researchers said that the complex engagement screens showed by males from many vital types will be strengthened through the phenomenon – for example, male. Levorerina Their mouths are open to females during performance.
Male birds often have these spots next to Black Stark [or] Martin added: “The additional effect of vital flood may help make these signal areas brighter while using them during the show.”
In females, however, the phenomenon may have a different function. She said: “The site of its vital feathers in many species is more in line with its potential use as camouflage.”
Martin added that the search is the new light on the well -studied birds. She said: “Even a caricature group like the Pardis birds, which have been widely studied, can still provide new visions in the vision of birds, behavior and morphology.”
