Songbirds' reproductive success reduced by natural gas compressor noise

February 18, 2021

Some songbirds are not dissuaded by constant, loud noise emitted by natural gas pipeline compressors and will establish nests nearby. The number of eggs they lay is unaffected by the din, but their reproductive success ultimately is diminished. That’s the conclusion of a team of Penn State researchers who conducted an innovative, elaborate study.
