It’s no secret. For years, we’ve known that bird species in America’s farmlands and grasslands have been in steep decline. The assumption was that this was due to habitat removal caused by agricultural expansion and the spread of cities into land once devoted to farming. Now a new study from Canada not only confirms the bird decline but challenges the commonly held wisdom. What’s doing away with all those birds? Pesticides.
News sources both large and small have called attention to the study. You can read it here (PDF). A 2009 interview with the study’s leader, Dr. Pierre Mineau, can be found here. Take away quote: “What I find really shocking is when a company does studies that show significant impacts and then continues to market the pesticide around the world. Take granular carbofuran. The first time they did the tests for the EPA they found 799 dead birds of a single species (a lark) in a few fields. Other species were affected also but not in such numbers. Nevertheless, it took about 15 years for that product to be removed from North America – it continues to be used worldwide.” (more…)
