SALT LAKE CITY (AP) — A California condor found dead at Zion National Park is believed to have died from lead poisoning after foraging on a bullet-ridden game carcass, in another setback for the recovery project on the Utah-Arizona border, officials said Monday.

Separately, two condors found dead in northern Arizona in December were confirmed by The Peregrine Fund to have died of lead poisoning. The latest fatality involved a 9-year-old female that had been observed searching nesting cavities together with a mate at Zion, which takes out a breeding pair.
