Environmental Contaminants

Conservation Science


Contaminants biologists in Region 3 conduct studies to identify problems from exposure to pollutants in migratory birds, endangered species, anadromous fishes, and on National Wildlife Refuges. The goals of studies are to develop resource management recommendations to mitigate problems.


Partnership exams the health of Neotropical migratory birds using the Mississippi River corridor for migration A study team of scientists from Illinois Wesleyan University, Illinois State University, U.S. Fish and Wildlife Service's Environmental Contaminants Program, and others capture and test birds while on their migration route from Latin American to the Central United States.  The study objective is to determine whether the birds have accumulated harmful concentrations of pesticides.  The pesticides tested include those that have been banned from the United States, but still in use by some Latin American countries.  Seventy two birds of 11 species were tested with 66 of them containing the now banned pesticide chemicals.  Tracking the presence of harmful chemicals help scientists monitor the health of migratory bird populations.
