Scientists have found that noisy, busy roads can affect bird behavior. How? Traffic noise impairs the animals’ ability to survive in an urban environment. The study was published in “Proceedings of the Royal Society B”. The researchers’ discovery could be of great importance to birds.
Professor Christopher Templeton of Pacific University in Oregon, USA, led the study, which he conducted in a behavioral laboratory with zebra finches. Researchers set the birds tasks both in a quiet environment and during traffic reconstruction. Traffic noise was found to reduce the birds’ ability to acquire new motor skills, remember locations of objects, control impulses, and learn by observing other birds. Specialists warn that such situations cause enormous disturbances in the life of animals and the system of their pairing. They influence how individual species will adapt to changing times.
There is growing evidence that human noise has a number of negative effects on wildlife.
