Selecting appropriate focal species for assessing the risk to birds from newly drilled pesticide-treated winter cereal fields in France.

Identifying focal bird species appropriate to the situation in which a plant protection product is used is important for refined risk assessment (EFSA ). We analyzed the results of extensive field observations of newly drilled cereal fields in France in autumn over 2 seasons to determine real bird focal species. In 2011, birds were observed before and after drilling on wheat and barley fields drilled with imidacloprid-treated seeds (i.
