Noisy natural gas equipment harms bird reproduction

Although some songbirds will nest near noisy natural gas pipeline compressors, and even lay the normal number of eggs, their reproductive success ultimately suffers, research finds. The researchers used unceasing playback of recorded compressor noise, 80 new, never-before-used nest boxes occupied by Eastern bluebirds and tree swallows, and behavioral observations with video cameras placed within boxes. “Importantly, the birds did not preferentially select quiet boxes over noisy boxes, suggesting they do not recognize the reduction in habitat quality resulting from the noise,” says study coauthor Margaret Brittingham, professor of wildlife resources in the Penn State College of Agricultural Sciences. “But both bluebirds and tree swallows nesting in noisy boxes spent less time incubating their eggs, had fewer eggs hatch, and produced fewer young than their neighbors nesting in quiet boxes.”

Ask An Expert: Bats on the Hardwood Ecosystem Experiment | Purdue Extension Forestry & Natural Resources

Join this edition of Ask an Expert video series with Dr. Joy O’Keefe and PhD candidate Elizabeth Beilke as they share about their studies of bats on the Hardwood Ecosystem Experiment. The HEE is in its initial stages and is planned as a 100-year project. Data were collected for two years prior to the first round of timber harvests and inventories have been conducted annually since, allowing us to quantify the varied responses of plants and animals to active forest management. This data will ultimately be used to develop management prescriptions that provide for resilient and sustainable managed forest ecosystems in Indiana.
