Urban Noise May Increase
Mortality of Songbirds, Study Finds
A new study says that urban noise may cause an increase in mortality among young sparrows
, suggesting that adult birds are less able to hear their hungry offspring above the clamor of their surrounding environment. In a long-term study conducted on a small, remote island off the UK coast, scientists from the University of Sheffield found that birds nesting in noisy areas were less effective at feeding their chicks than those living in quiet areas, and actually produced fewer offspring. Chicks that were reared in a loud barn, for instance, were lighter when they were ready for flight, a factor that could affect a young bird’s chances for survival, said Julia Schroeder, co-author of the study published in the journal PLoS ONE
. “There are lots of studies on great tits and urban noise, but these tend to focus around mate choice, where the male advertises its quality to the female,” Schroeder told BBC News. “But the idea that the communication between parents and offspring could be affected in cities is fairly new.”
