Songbird Declines Linked to Acid Rain

A study published in August 20th issue of the Proceedings of the National Academy of Sciences by Stefan Harness and co-authors provides strong evidence that acid rain is a major factor responsible for population declines of the Wood Thrush in the eastern United States. Read the abstract and the press release issued by Cornell University. The study is significant because previous research into the causes of songbird population declines have focused on the effects of habitat fragmentation on breeding and wintering grounds.

Popular accounts of the results of this study have also been published by Robert Winkler (for National Geographic News) and Charles Seabrook (for Cox News Service).
