Herring Gulls Diet Changes
A team from the National Wildlife Research Center in Ottawa, Canada analyzed 25 years of data on herring gulls and found that throughout the Great Lakes region, the birds were in poor health in many areas. Tests of their fatty acids showed an increase in the type of transfat that mostly comes from food produced by humans. This comes after the introduction and restoration of trout and salmon species in the Great Lakes, which compete for food at the top of the food chain.
