A younger bald eagle has died because of to ingesting rodent poison, marking the next in 5 months in Massachusetts, MassWildlife introduced on Thursday.

A younger woman eagle was observed in “obvious distress” on the floor in Middlesex County in July and was taken to the Tufts Wildlife Clinic in Grafton, authorities mentioned. On Thursday, MassWildlife announced the eagle experienced died.

A necropsy and toxicology examination verified that the eaglet’s bring about of loss of life was owing to lethal amounts of second-technology anticoagulant rodenticide (SGAR) poisoning. It was the next ever documented case of an eagle dying from rodenticide in the point out, MassWildlife claimed. The initially involved an grownup eagle that died in March.

Analysis of liver tissue confirmed two distinctive SGARs ended up ingested by the eaglet, MassWildlife stated. Given the hunting variety of eagles, it is unattainable to establish the exact supply of this rodenticide poisoning, authorities explained.

Anticoagulant rodenticides are a type of rodent poison that kills by avoiding blood from clotting typically, ensuing in fatal interior hemorrhage or bleeding, MassWildlife said.

The poison while can not only eliminate the intended concentrate on, but also a predator or scavenger that eats the prey just after they die. Scientific studies of birds of prey in Massachusetts executed at Tufts Wildlife Clinic have revealed common exposure to SGARs, authorities reported.

The U.S. Environmental Safety Agency has imposed limits on rodenticides. SGARs aren’t be sold as a result of normal purchaser shops for use by the typical home-owner, MassWildlife stated. SGARs can nevertheless be ordered on-line in commercial use quantities for use only by certified pest specialists and agricultural consumers.

Although bald eagles mostly eat fish, they are opportunistic foragers and will scavenge or prey on a assortment of animals, MassWildlife claimed.

Extra than 80 pairs of bald eagles nest in Massachusetts.
