Summary
Conclusions: There was a significant reduction in ovenbird pairing success at compressor sites (77%) compared with noiseless wellpads (92%). These differences were apparent regardless of territory quality or individual male quality. Noise interferes with a male's song, such that females may not hear the male's song at greater distances and/or females may perceive males to be of lower quality because of distortion of song characteristics Thresholds/Learnings: Synopsis: Anthropogenic noise is rapidly increasing in wilderness areas as a result of industrial expansion. This study assessed pairing success and age distribution of male ovenbirds, Seiurus aurocapilla, in the boreal forest of Alberta, Canada, in areas around noise-generating [...]

Thresholds/Learnings:
Synopsis: Anthropogenic noise is rapidly increasing in wilderness areas as a result of industrial
expansion. This study assessed pairing success and age distribution of male ovenbirds, Seiurus
aurocapilla, in the boreal forest of Alberta, Canada, in areas around noise-generating compressor
stations compared with areas around habitat-disturbed, but noiseless, wellpads. The study found a
significant reduction in ovenbird pairing success at compressor sites (77%) compared with noiseless
wellpads (92%). These differences were apparent regardless of territory quality or individual male quality.
Significantly more inexperienced birds breeding for the first time were found near noise-generating
compressor stations than noiseless wellpads (48% vs. 30%). Noise interferes with a male's song, such
that females may not hear the male's song at greater distances and/or females may perceive males to
be of lower quality because of distortion of song characteristics
