The skin on the necks will vary in color, depending on the age of the birds. Ĭalifornia condors' wingspan measures up to 2.9 m (9 ft 6 in), and they can weigh up to 10.4 kg (22 lb 15 oz). Overall length can range from 117 to 135 cm (46 to 53 in) Measurements are usually taken from specimens reared in captivity. The female, contrary to the usual rule among birds of prey, is smaller than the male.Īlthough the California condor is, from beak to tail, about five cm (2 in) longer, the Andean condor has a wider wingspan, ranging from 274–310 cm (9 ft 0 in–10 ft 2 in) and heavier, reaching up to 11 to 15 kg (24 to 33 lb) for males and 7.5 to 11 kg (17 to 24 lb) for females. The feet are thus more adapted to walking as in their relatives the storks, and of little use as weapons or organs of prehension as in birds of prey and Old World vultures. The middle toe is greatly elongated, and the hinder one but slightly developed, while the talons of all the toes are comparatively straight and blunt.
