Lead toxicosis remains the primary cause of death in wild populations of California condors
"I visited the [Scheid] site several years ago, and based on my opinion about the condors
' potential to collide with these structures, I recommended that Foundation Windpower do a study," Stake recalls.
Chris Goss's 2016 book "Fw 200 Condor
Units of World War 2" details the service of a little known German aircraft that might have been among the most effective of the early 1940s--if only for its damaging psychological effects on Allied morale.
THE endangered California condor
is making a comeback in the wild three decades after the giant bird nearly became extinct.
"Lead, which condors
consume when scavenging at carcasses of animals killed with lead ammunition, is the main factor limiting their recovery; lead toxicosis was responsible for 26 percent of juvenile condor
deaths and 67 percent of adult condor
deaths between 1992 and 2009," according to a statement by AOS.
Freelance writer and photographer Chuck Graham lives one mountain range away from the Condor
Trail, where he's spent much time photographing endangered California condors

In late 1984 and early 1985, six California condors

usually produce only one egg, but workers at the Idaho facility plan to remove some eggs so the breeding pairs produce a second egg.
Those fragments poison more than just condors
. Some 500 peer-reviewed studies have detailed the negative impacts of lead ammunition on 130 wildlife species worldwide, including bald eagles, golden eagles, and turkey vultures.
About 30 percent of blood samples collected annually from free-flying condors
in California show lead concentrations high enough to affect the birds' physiology, Finkelstein and her colleagues report.
