小鸟别上当！镜子里藏着“假天空”

Group 1 - A mirror tower named "Floating Soil" was recently dismantled after being identified as a deadly trap for birds at Dongting Lake, which is a significant stopover for migratory birds [3][4][5] - The tower created a deceptive reflection of the sky and surrounding environment, leading birds to collide with it, as they could not recognize it as a solid object [8][9][10] Group 2 - Birds are unable to see glass and mirrors due to their evolutionary history, as these materials have only been widely used by humans in recent times, while birds have evolved to recognize only reflective surfaces like water [8] - The positioning of birds' eyes provides a wide field of view but limits their ability to detect obstacles directly in front of them, making them susceptible to collisions with transparent barriers [9] - Solutions have been proposed to make glass more visible to birds, such as applying dots or lines on glass surfaces and using special coatings that reflect ultraviolet light, which birds can see [11][12]
