	abstract = {As energy development expands into Alberta{\textquoteright}s boreal forest, sources of chronic industrial noise also increase. I found that many passerine species are present in lower densities in areas impacted by chronic industrial noise; over one-third of species analysed had lower abundances in these areas. Passerines as a whole had a 37\% reduction in density near compressor stations. Male Ovenbirds ( Seirus aurocapilla ) were 15\% less likely to successfully pair with a female in noise-affected areas. There was an 18\% increase in the number of first-year breeders in noisy areas, implying that competition with older birds may be forcing younger birds out of optimal, quieter habitat. Finally, if birds learn to alter their song{\textquoteright}s frequency in areas with substantial background noise these effects may be minimised; Swainson{\textquoteright}s Thrush ( Catharus ustulatus ) appears to have this ability although the Ovenbird and Red-eyed Vireo (Vireo olivaceus ) do not.},
