GLEN ELLYN, Ill. (CBS) -- A bald eagle found in Chicago's western suburbs has been euthanized after it was suspected of being infected with bird flu.

On Friday of last week, the eagle was spotted with its head drooping in Hinsdale. It eventually flew a short distance before handlers from Chicago Bird Collision Monitors were able to capture it.

The organization said the eagle was displaying head shaking or tremors, and was walking in circles.

The eagle was able to fly, but fell from a tree after trying to perch, Chicago Bird Collision Monitors said.

Sadly, the eagle had to be euthanized at the DuPage Wildlife Conservation Center in Glen Ellyn one day after being captured.
