Researchers from the U.K.’s University of Sheffield found that noise can interfere with nestlings’ ability to communicate that they are hungry.
This can result in them becoming malnourished compared to birds raised in more quiet environments.
Other research has indicated that a shortage of food for chicks during summer appears to be responsible for a 66 percent decline in the U.K.’s sparrow population between 1970 and 2009.
The latest study compared the weight of birds leaving the nest near a loud power generator on Lundy Island with those in quieter areas.
Birds living in quiet barns and woodlands were fed more by their parents than those around the generator, meaning they had a better chance of survival.
