Storks could become poisoned by pesticides during their migration to Africa

Recommended Posts

Not all storks migrate to Africa. Many stay for the winter in the Iberian Peninsula, where landfills have become a permanent source of food. Scientists have analyzed the presence of pollutants and pesticides (some prohibited in Spain) in the blood of nestlings from three colonies, two of which are close to landfill sites. The results reveal that the main source of contamination can be due to the use of insecticides still used in African countries where the birds migrate to, who transfer their contaminated load onto their offspring through their eggs.kHMSMysuC8c
