Urban noise can be house sparrows’ declining cause
A recent study suggested that the noise in urban areas could be increasing the mortality rate among house sparrows. The UK’s population has been declining since the 1970s.
The researcher found that birds nesting in noisy areas were less effective at feeding their chicks compared with those nested in quiet places.
Noise seems to interrupt the communication between the chicks and their parents.
According to BBC the Plos One Journal published the findings of the scientists from the University of Sheffield. Co-author Julia Schroeder explained that “chick provision is strongly linked to chick survival because if they do not get fat then they die."
