There were a few factors that went into the California Condor's near-extinction. One factor was the breeding habits of the condor. The condor only has one egg every other year; therefore, birth rates for this bird are naturally low. Many of the problems faced by the condor are man-made. Condors hit power lines and are electrocuted. Condors are also susceptible to pesticides used to kill rodents. Pesticides accumulate in the condor's bloodstream over several decades and cause either death or infertility. Condors also experience lead poisoning from eating dead animals.
Thanks to captive breeding programs, the California Condor has made a significant recovery, though it is still in danger. Pesticides are still a danger to its populations, as is eating lead shot. Condors must be constantly monitored in the wild and treated for lead poisoning. Baby condor chicks also eat trash. Ensuring healthy chicks is especially critical when condors only have one egg every other year. Though condors that have been raised in captivity have been able to avoid power lines, these still remain a threat to these birds.
We may find different things fascinating, but I was most impressed with the range of the condor shown on the map within the first few minutes of the video. The condor ranged from California to Mexico. I would also like to see some follow-up information on how the general public perceives the condor preservation program. I am impressed by the condor's longevity and I would like to know how the researchers determined the age of the oldest condor.
