California Condor

In 1805, Lewis and Clark were amazed by the largest bird they encountered: the California condor. These birds have a wing span of up to 10 feet.

The California condor’s range is British Colombia south to Baja California. These birds eat careon. Carrion is dead anamils like cattle, sheep, horses , and bison.

The California condor is a bird that almost extent. The birds decline because California condors are lead poisoning, electrocution by colliding with power poles and poaching or accidental shooting and low reproductive rate. They came back from the brink of exteention because people became aware that they were dieing out and wanted them not to die out so thet cut on the pollution and started to become awaepre how many condors there are.

The last official sighting of a condor in Oregon was in 1904. By 1987 only 27 birds existed in the world. The last wild condors were taken into captivity in 1987. There were no California condors in the wild between 1988 and 1991. Condors were released back into the wild starting in early 1992; that is still happening. The Oregon Zoo has a condor breeding facility.

There are now more than 160 wild condors California, Arizona and Mexico.
