Weak Recovery of Bird Species after Neonic Ban with Exceptions in France, Persistence Cited
(Beyond Pesticides, December 5, 2025) A study published this month in Environmental Pollution analyzes the role of neonicotinoid insecticide exposure on bird populations, finding a significant negative effect of imidacloprid use on insectivorous bird abundance. In comparing the effects of the insecticide imidacloprid on bird abundance in France before and after the 2018 ban, the researchers show a weak recovery of bird populations after 2018. The persistent nature of imidacloprid, however, as well as the continued use of other petrochemical pesticides that have adverse effects on bird species, continues to impact populations of all types of birds and other wildlife, leading to cascading impacts on biodiversity.   “Our study shows that imidacloprid is a major covariate of the abundance of birds, in addition to other pesticides that are also negatively related to bird populations, and that these effects are not uniform across species,†the authors report. They continue in saying that the relationship between neonicotinoids and bird abundance varied across bird diets, as “the abundance of insectivorous birds was consistently lower under increasing pesticide use, in particular imidacloprid.†Background As shared in the study and on Beyond Pesticides’ Birds page, bird species can be exposed to pesticides directly through ingestion […]
