California condors are one of the rarest birds in the world and the largest land bird in North America with a wingspan of 9 1/2 feet and weighing up to 22 pounds. Adults are grayish-black except for triangle-shaped patches of white underneath their wings. These patches are visible when condors are flying overhead. Males and females are identical in size and plumage. The bare heads of condors are grayish-black as juveniles and turn a dull orange as adults.
