Paradise birds are families of small to medium-sized forest birds found in the New Guinea region. With its elaborate and colorful feathers, these birds are one of the most beautiful creatures on the planet. A new study found that ornithologists at the American Museum of Natural History and ornithologists at the University of Nebraska Lincoln University were biological fluorescents out of 45 currently recognized paradise. They suggest that this special “brightness” is important among male birds due to hierarchy and mating displays.
With colorful feathers and intricate courtship displays, the paradise bird has a special place in natural history.
They serve as examples of school books for sexual choice. This is the result of the selection of male female peers with attractive features.
The results show unparalleled radiation of species in which men exhibit extreme morphological features and behaviors, and behaviours that have no evolutionary meaning other than attracting women due to coalescence.
“The unique mating rituals and exhibitions of paradise birds fascinated scientists and promoted countless research focusing on the evolution of traits and sexual choice,” said Rene Martin, PhD, University of Nebraska, Dr. Lincoln. The doctor said.
“It seems appropriate that these flashy birds are likely signaling each other in an additional flashy way.”
Biofluorescence is a phenomenon that occurs when an organism absorbs light, converts it, and releases it as a different color.
“More than 10,000 people recorded birds and despite numerous studies that included bright feathers, elaborate mating displays and excellent vision, we surprisingly investigated the presence of biological fluorescence. There are very few people.”
“Bowerbirds and Fairy Wrens were unable to shine, but bright green yellow fluorescent light was found among the bird birds.”

Researchers discovered that when exposed to not only bird light, but also purple light, the birds also fluorescently, and that the birds emitted fluorescence.
This phenomenon is particularly prominent in men, focusing on the bright feathers and skin of the area highlighted during the exhibition: the mouth and bills of the head, neck, and belly.
In women, biological fluorescence is usually restricted to feathers in the chest and belly.
“These birds live near the equator, where bright sunlight is abundant all year round, and in forests where light complexity is heavily affected by different canopy differences, enhancing bioflaorent signals. It could be,” Emily said. Kerr, PhD student at the American Museum of Natural History.
“Studies based on closely related species found that bird eye pigments align with fluorescent peaks measured by researchers.”
“Based on this, we speculate that avian paradises can see these biological fluorescent patterns, which enhance the contrast with dark feathers and possibly play an important role in courtship and hierarchy. there is.”
