We document causes of death in free-ranging California Condors (Gymnogyps californianus) from the inception of the reintroduction program in 1992 through December 2009 to identify current and historic mortality factors that might interfere with establishment of self-sustaining populations in the wild. A total of 135 deaths occurred from October 1992 (the first post-release death) through December 2009, from a maximum population-at-risk of 352 birds, for a cumulative crude mortality rate of 38… 
15–20 Viner, condor mortality
Over the past 30 years, the California condor (Gymnogyps californianus) population has rebounded from 22 individuals to more than 200 birds living in the wild. Historical impacts on the population
Characteristics of feeding sites of California Condors (Gymnogyps californianus) in the human-dominated landscape of southern California
ABSTRACT Wildlife conservation is often improved by understanding the movement ecology of species and adapting management strategies to dynamic conditions associated with movement. Despite a
Effects of Lead Exposure, Flock Behavior, and Management Actions on the Survival of California Condors (Gymnogyps californianus)
TLDR
It is found that as flocks have increased in size and age, condors are increasingly likely to range more widely and less likely to be observed feeding on proffered food, and these “wilder” behaviors were associated with lower survival.
Spatiotemporal Patterns and Risk Factors for Lead Exposure in Endangered California Condors during 15 Years of Reintroduction
TLDR
Lead exposure was a pervasive threat to California condors despite recent regulations limiting lead ammunition use and significantly increased as age and independence from intensive management increased, highlighting the challenges of restoring endangered vulture populations as they mature and become less reliant on management actions necessary to compensate for persistent threats.
Resource Selection by the California Condor (Gymnogyps californianus) Relative to Terrestrial-Based Habitats and Meteorological Conditions
TLDR
It is found that condor use of terrestrial areas did not change markedly within the annual cycle, and thatcondor use was greatest for habitats where food resources and potential predators could be detected and where terrain was amenable for taking off from the ground in flight.
ANALYSIS OF HISTORICAL MEDICAL RECORDS OF CALIFORNIA CONDORS (GYMNOGYPS CALIFORNIANUS) ADMITTED FOR LEAD EXPOSURE TO THE LOS ANGELES ZOO AND BOTANICAL GARDENS BETWEEN 1997 AND 2012: A CASE SERIES STUDY
TLDR
A better understanding of how intervention and therapeutic approaches have been essential for the recovery, release, and sustainability of these birds as a wild population is contributed to.
California condors and DDT: Examining the effects of endocrine disrupting chemicals in a critically endangered species

TLDR
Non-invasive, in vitro estrogen receptor (ESR) activation assays are conducted to characterize activation by EDCs that coastal condors encounter, highlighting the potential implications of EDC exposure on the continued recovery of the California condor.
Comment on "Terrestrial Scavenging of Marine Mammals: Cross-Ecosystem Contaminant Transfer and Potential Risks to Endangered California Condors (Gymnogyps californianus)".
TLDR
In overlooking these contaminant and reproductive data from the original wild population of condors, Kurle et al. missed evidence that condors may well be among the species that are relatively resistant to DDE effects, and suggested that DDE was the primary cause of difficulties.
Condors in space: an individual-based population model for California condor reintroduction planning
Existing demographic models of California condors have not simultaneously considered individual condor movement paths, the distribution and juxtaposition of release sites, habitat components, or

Bullet Fragments in Deer Remains: Implications for Lead Exposure in Avian Scavengers
TLDR
In radiographs of selected portions of the remains of 38 deer supplied by cooperating, licensed hunters in 2002–2004, radiographs found metal fragments broadly distributed along wound channels suggest a high potential for scavenger exposure to lead.

Feather lead concentrations and (207)Pb/(206)Pb ratios reveal lead exposure history of California Condors (Gymnogyps californianus).
TLDR
It is shown that lead concentration and stable lead isotopic composition analyses of sequential feather sections and concurrently collected blood samples provided a comprehensive history of lead exposure over the 2-4 month period of feather growth, demonstrating the utility of using sequentially sampled feathers to reconstruct lead exposure history.
Lead and lead toxicity in domestic and free living birds
TLDR
There is, therefore, no doubt that millions of birds die annually worldwide from lead poisoning (in the U.S.A., around 3’000 000), this problem being most acute in marshland.
