I find it interesting how many people here have instantly taken the same position as the Animal Rights folks. Assumed a hunter shot the bird.

What part of the article points to a hunter as the cause of death?

"The eagle was found in Clearfield County near the Penn/Pike township line, just north of the Curwensville Dam in the vicinity of Kirk Street extension, Lumber City. Dusza noted that Wildlife Conservation Officers (WCOs) Dave Stewart and Chris Ivicic are investigating this incident and is asking the public for information about the person/persons responsible.

A concerned citizen reported finding the eagle to the Game Commission on Sunday, May 15. According to WCO Stewart, a necropsy determined that the eagle was killed with a shotgun between Tuesday, May 10, and Saturday, May 14, and died where it was shot."
