• Condors pair for life and breed once every two years, producing only one egg.

• Condors roost, or sleep, in large groups. They "talk" to each other with hisses, growls, grunts, and body language.

• From tip to tip, their wings can stretch up to 9 feet.

• Instead of flapping their wings, condors soar on wind currents.

• Condors are scavengers, which means they eat animals that are already dead. But they don't rely on their sense of smell. They watch for other scavengers eating dead animals.

• In 1982, there were fewer than 25 California condors left in the wild. Today, there are about 200.

• Hunting
