The video in this story is from a previous report. A bald eagle was found dead from suspected bird flu in recent days in a forested area of the northwest suburbs, another signal of how serious the disease has gotten for wild creatures as well as farm animals.

Rising numbers of great-horned owls, bald eagles and red-tailed hawks have been getting sick and dying of bird flu this winter as the virus continues to mutate and circulate in North American wildlife.

A bald eagle in Massachusetts had to be euthanized after it showed signs of neurological deficits and tested positive for bird flu. In a video shared by Raptor Tales Rescue of Shrewsbury, the bird could be seen having “sudden and frequent head movements.” This was cause for concern for it having avian influenza, also known as bird flu.
