A tip last March led investigators to Parker's property, where they discovered 159 dead animals, mostly red-tailed hawks. They also found two bobcats, a stuffed mountain lion and an owl, the Chronicle reported.
"Poaching is not a game, it's a serious crime," Attorney General Xavier Becerra said in a statement. "Richard Parker willfully and egregiously disregarded California law to kill protected wildlife, including hawks. To anyone who breaks our laws for illegal sport, know that we will prosecute and hold you accountable."
