It is often difficult, if not impossible, to tease apart the many factors making life more and more difficult for migratory birds and to determine the relative contribution of each factor to population declines. Birds that breed in the United States and Canada and winter in Latin America and the Caribbean are potentially exposed to more pesticides than are resident birds, given the great distances over which they travel.

Researchers from Belgium wanted to investigate what was killing thousands of newborn birds in Flanders and Brussels. There are lots of things you can do to help lower pesticide and herbicide exposure for wildlife and insects alike.
