Insect-eating bird populations in France appear to be making a tentative recovery after a ban on bee-harming pesticides, according to the first study to examine how wildlife is returning in Europe.
Neonicotinoids are the world’s most common class of insecticides, widely used in agriculture and for flea control in pets. By 2022, four years after the European Union banned neonicotinoid use in fields, researchers observed that France’s population of insect-eating birds had increased by 2%-3%. These included blackbirds, blackcaps and chaffinches, which feed on insects as adults and as chicks.
