A bald eagle rescued from the Housatonic River on Saturday died this morning.

Wildlife rescue "Christine's Critters" shared the update on Facebook.

“We were preparing to administer her chelation and fluid therapy, and she simply closed her eyes and passed away peacefully,” the post says.

Boaters originally spotted the eagle near Wooster Island and called emergency officials. It was brought to the rescue by Connecticut Department of Energy and Environmental Protection crews and Shelton firefighters.

Christine's Critters says they plan to do a necropsy to learn more about the bird's cause of death.
