Do pesticide coatings on agricultural seeds pose a threat to earthworms and to the birds that eat them?

Earthworms are a vital part of a healthy, functioning soil ecosystem and are also an important protein-rich food source for wildlife, including many species of birds and mammals. In an agricultural setting, the presence of earthworms can increase crop yields by 25%, but can also expose earthworms to pesticides. Seed treatment is the principal application method for neonicotinoid insecticides,...
