Annual bird mortality in tar sands tailings ponds exceeds government/industry figures: Study

Edmonton - A study in the peer-reviewed journal The Wilson Journal of Ornithology to be published in early September (online in late August) shows annual bird mortality in the bitumen tailings ponds of northeastern Alberta - an internationally significant migratory bird corridor - greatly exceeds industry estimates.

The authors investigated three types of data: government-industry reported mortalities; rates of bird deaths at tailings ponds; and rates of landing, oiling, and mortality to quantify annual bird mortality due to exposure to tailings ponds.
