How does the eye -catching color of birds be in danger?

China Biological Diversity Protection and Green Development Foundation (referred to as the China Green Fair, Green Association) is a partner of the Convention on Protection of Wildlife Migration Species (CMS). In -depth participation in global biological diversity governance and biological diversity mainstream. Recently, the Chinese Greenford Bird Watching Working Group learned from the international well -known journal "How to make them in danger" (how songbirds' striking colors put the risk). This article is compiled as follows, for the reference and understanding of interesting readers.

According to reporters published in "Contemporary Biology" on September 15, the bright and unique color poultry facing a higher risk of extinction, it is more likely to be regarded as a pet transaction. Researchers also predict that there are nearly 500 kinds of birds, most of which live in tropical regions. Because of their unique and ideal colors, they face the risk of future trade.

"Aesthetic value is an important part of how people evaluate nature," said the Rebecca classmate of Duoren University in the United Kingdom. them. Ming poultry is highly sought after in pet trade, especially because of their beautiful singing. However, Ming poultry can also be very colorful -this is the ideal characteristics of other common trading species such as parrots. "

In their new studies, students, including the University of Gaysville Florida's Brett Scheffers and their colleagues, explored the aesthetic value of aesthetic value in the protection of biodiversity. They use novel color measurement to evaluate the aesthetics of birds and birds in all parts of the world.

Their analysis shows that tropical areas are the center of bird colors, with 91%and 65%of the world's most diverse and most unique colors, respectively. They reported that pet trade affected 30%of birds, and its goal was in groups of related and unique colors. They continue to identify 478 birds that may face trade risks in the future based on their attractive colors.

"We are surprised to see the intensity of color latitude gradient; even if considering the more species in tropical areas, the diverse color diversity of tropical areas has made all other regions dwarfing," the classmate said.

Although people may think that bright blue, orange and yellow can make the species in danger, researchers are also surprised to find that pure white is a unique color found in many popular species, such as the endangered Bali, which is endangered in Bali. Island Eight Brother. The results of the survey generally emphasized that some people are willing to travel around the world just to see the same color characteristics of the birds through the binocular telescope and may also make them face the risk of pet transactions. These findings are of great significance to protection.

"The motivation for understanding trade may require more active protection of risk -free risk species," the classmate said. "By better understanding the content of the transaction and the location and reason for the transaction, trade can be able to be sustainable and managed. The loss of colorful species also directly erodes the aesthetic value. Bad, this value is often fundamentally inspired and funded. "

In future research, they want to solve more factors that affect the district differences of bird trade models. They also want to explore the role of colors in other animal and plant trade.
