Condor visits Wyoming; next condor needs to find steel instead of lead
By Barb Gorges
Exciting news in the Wyoming birdwatching community: A California condor, North America’s largest raptor with 9.5-foot wingspan, was sighted July 7 west of Laramie perched on Medicine Bow Peak. The reporting birder was Nathan Pieplow. He is the author of the Peterson guide to bird sounds. Maybe he recorded it.
Wing tags printed with a big T2 declared this was a female condor hatched and raised in 2016 at the Portland, Oregon, zoo and released in March at the Vermilion Cliffs National Monument in northern Arizona.
Several people from the Laramie Audubon chapter climbed up to see the condor. Brian Waitkus got excellent photos.
Medicine Bow Peak, elevation 12,014 feet, is a popular destination for hikers who want a challenge including lightning and boulder fields. As many as a dozen hikers were congregating near the condor July 9. The condor didn’t mind people but was flushed by three dogs off leash, observed Murie Audubon president Zach Hutchinson.

T2 was one of many condors released into the wild by the Peregrine Fund working to re-establish the population of this officially endangered species. In 1982 there were only 22 birds left. Today there are 500, half flying free in Arizona, Utah, California and Baja Mexico. Some are now breeding in the wild. For more, read Condors in Canyon Country by Sophie A. H. Osborn and https://www.peregrinefund.org/.
The distance between the Arizona release site and the peak is only 440 miles as the condor flies, not difficult for a bird that can travel 200 miles a day. T2 was spotted earlier, on June 28, near Roosevelt, Utah.
The closest previous Wyoming condor sighting was 1998, in Utah at Flaming Gorge Reservoir, which spans the Utah-Wyoming line.
T2’s visit was brief. A Peregrine Fund researcher following the condor using telemetry later got the signal 30 miles away indicating the bird was not moving. By the time he arrived, the bird was dead. It’s been sent to U.S. Fish and Wildlife Service for autopsy. Foul play was not suspected.
Serendipitously, soon after the first news broke about T2, Chris Parish, director of global conservation for the Peregrine Fund, was about to drop his daughter off in Laramie. He offered to give a talk on condors sponsored by the Laramie Audubon Society and the University of Wyoming Biodiversity Institute.
In his presentation, Chris touched briefly on the history of restoring the condor population.
Condors are tough. They survived the large mammal extinction 10,000 years ago. However, they are slow to reproduce, only one chick every two years. At propagation centers, experts can get a pair to lay an extra egg to put in an incubator.
Condors live 50 to 60 years by avoiding predators and finding new habitat. A few are still being shot, despite condors being as harmless as turkey vultures, eating only carrion–already dead animals. They fly into powerlines and get hit by vehicles too.
The biggest problem for condors is poisoning from lead ammunition, Chris said. When a deer is shot, the bullet disintegrates into hundreds of fragments. Often, the fragments are in the gut pile, or offal, that hunters leave in the field. Offal is the condor’s main dish.
All those little lead fragments add up and eventually cause lead poisoning. Some of those lead fragments also find their way into game meat people eat. Researchers try to check the blood lead levels of all free-flying condors once a year and treat them if necessary before releasing them again.
Our national symbol, the bald eagle, also feeds at carcasses. In 1991 lead shot for waterfowl hunting was banned but upland animals—and birds like the eagle–are not protected.
Arizona Game and Fish Department a few years ago asked hunters on the Kaibab Plateau, where condors are released, to voluntarily use steel ammunition or to remove offal. They offered each participant two free boxes of steel ammunition. Participation is now at 87 percent. A similar program is nearly as successful in Utah. California has banned lead ammunition since 2008, said Chris.
The Peregrine Fund holds shooting trials and gives away steel ammunition for hunters to test. Chris, a lifelong hunter, spouts ballistic statistics with ease. The bottom line is that lead and steel ammunition of comparable quality are nearly the same cost. However, manufacturers need encouragement to offer more variety.
Chris also said that yes, steel ammunition takes a little practice for the hunter to become proficient with it, but practice is required any time a hunter switches to the same caliber ammunition made by a different manufacturer.
Steel bullets aren’t silver bullets for all wildlife problems. But maybe Wyoming can join the steel states. That way we’ll make it safer here for when more condors show up.
