Famous Boston Bald Eagle Treated for Poisoning Symptoms

A bald eagle known for frequenting the Mystic River in the Boston area was treated by staff at the New England Wildlife Center (NEWC) in Weymouth, Massachusetts; veterinarians suspect that the bird ate a poisoned rodent.

The eagle, colloquially known as MK, was found in ill health in Arlington on Monday, February 27, according to NEWC.

In a Facebook post, NEWC said that MK remains in critical condition after suspected anticoagulant rodenticide poisoning, which occurs when an animal eats a rodent that has already ingested poison.

“Our veterinary team will be by her side and monitoring her closely as we try to get her through this,” the caption read.
