Endangered California condors still face lead poisoning threat

[zigzag3143]

It may not be the most charismatic species, but the endangered California condor, a bird with an incredible wingspan of nearly 10 feet, has received a lot of attention over the years. After dropping to a population of just 22 individuals in the early 1980s, captive breeding programs have boosted their numbers to around 400, with some 200 living in the wild. Even that small population is extremely high-maintenance, however. All the birds are tracked by radio or GPS tags, and most are caught every other year for medical examination and treatment.
