This is a California condor video from the USA.
Recent reports and studies of a struggling California condor population indicate the persistence of DDT contamination, underscoring long-standing concerns that the chemical pesticide and its related byproduct chemicals continue to threaten animal life and affect human health: here.
June 2011: Recent episodes of lethal lead poisoning in California condors have biologists asking for more help from the public to conserve endangered condors in northern Arizona and southern Utah: here.
Three California condors will be released to the wild in the Vermilion Cliffs National Monument in northern Arizona next month: here.
Scientific paper shows California condor still threatened by human activities: here.
California condors numbers pass the 400 mark for the first time for 100 years: here.
A comprehensive study led by environmental toxicologists at the University of California, Santa Cruz, shows that California condors are continually exposed to harmful levels of lead, the principal source of that lead is ammunition, and lead poisoning from ammunition is preventing the recovery of the condor population: here.
August 2012. A Peregrine Fund biologist has provided visual confirmation that a wild-hatched California condor chick is present in a nest cave deep in Grand Canyon National Park. That brings to three the number of wild condor chicks produced by the Arizona-Utah flock this season: here.

DDT Linked to Long-Term Decline of Insect-Eating Birds in North America, Through Analysis of Bird Droppings: here.
To control pest outbreaks, airplanes sprayed more than 6,280 tons of dichlorodiphenyltrichloroethane (DDT) onto forests in New Brunswick, Canada, between 1952 and 1968, according to Environment Canada. By 1970, growing awareness of the harmful effects of DDT on wildlife led to curtailed use of the insecticide in the area. However, researchers have now shown that DDT lingers in sediments from New Brunswick lakes, where it could alter zooplankton communities: here.
Some Canadian lakes still store DDT in their mud: here.
