Avian Haven, a rehabilitation center for wild birds in Freedom, Maine, had to euthanize this eagle, the last survivor of the five lead-poisoned Bald Eagles admitted to the center in the first two weeks of January.

This bald eagle was admitted to Avian Haven on Jan. 6, after being found lying down on the ice of Flanders Pond. Its blood lead level was so high it was off the scale of the centers screening instrument, according to an Avian Haven Facebook post. It is one of five Bald Eagles with lead poisoning admitted to the rehabilitation center in the first two weeks of January. (None of them survived.) It takes only a tiny fragment of lead to debilitate or kill a Bald Eagle. Avian Haven asks hunters not to leave game meat shot with lead in the field.

The female bald eagle Jason Dolloff and his daughter, Carrigan Robinson, rescued Sunday from the Androscoggin River in Peru had a gunshot wound and elevated lead levels in its blood. The protected bird died that night.
