EASTON, Md.- Five bald eagles found dead near Easton were poisoned with carbofuran, according to recently released documents from U.S. Fish & Wildlife.

These five eagles, discovered in Jan. 2017, were killed by the same substance linked to the deaths of 13 eagles near Federalsburg in February 2016, according to U.S. Fish & Wildlife findings.

Candy Thompson of the Maryland Natural Resources Police says her agency assisted U.S. Fish & Wildlife with the removal of the dead birds.

U.S. Fish & Wildlife took possession of the dead birds for toxicology, but had not released its findings on cause of death until WNAV reporter Donna Cole submitted a Freedom of Information Act request demanding the necropsy reports.

The released reports found the eagles died of carbamate intoxication from Carbofuran, a pesticide banned on food crops by the EPA nearly a decade ago.

Eagles are protected by a Bald and Golden Eagle Protection Act and a Migratory Bird Treaty Act.
