Regarded as one of the rarest birds in the world, the California condor (Gymnogyps californianus) is the largest land bird in North America with a wingspan up to 9 1/2 feet and weighing up to 23 pounds. Adults are primarily black except for triangle-shaped patches of bright white underneath their wings. These patches are visible when condors are flying overhead and offer a key identification characteristic.

Males and females are identical in size and plumage. The bare heads of condors are grayish-black as juveniles and turn a dull orange-pink as adults. Condors are members of the New World vulture family and are opportunistic scavengers, feeding exclusively on dead animals such as deer, cattle, rabbits, and large rodents.
 
Using thermal updrafts, condors can soar and glide at up to 50 miles per hour and travel 100 miles or more per day searching for food while expending little energy.

When not foraging for food, condors spend most of their time perched at a roost. Cliffs, tall conifers, and snags serve as roost sites in Grand Canyon National Park.

Condors become sexually mature at about six years of age and most mate for life.

Nest sites are often found in caves and rock crevices. Condors do not build nests. Instead, an egg about 5 inches in length and weighing around 10 ounces is deposited on bare ground. Condors typically lay a single egg every other year. The egg hatches after 56 days of incubation and both parents share responsibility for incubation and for feeding the nestling. Young condors leave the nest when they are 5 to 6 months old.

There are currently 73 condors flying free in northern Arizona and southern Utah, including several that were raised in wild nest caves within or near to the Grand Canyon.


 

The rest come from the captive breeding program. Even the wild-raised birds are mostly now wearing numbered tags and transmitters. The numbers allow you to learn more specifics about any bird you get a close look at.

So look out for these magnificent birds soaring on their 9-foot (nearly 3-meter) wingspan over Grand Canyon National Park. During the warmer months they are seen regularly from the South Rim and frequently also from the North Rim. On the South Rim, try scanning the cliffs and Douglas-fir trees below the Bright Angel Lodge late in the afternoon. In this area some condors select overnight roosts from late April through July and to some degree from March through October.
