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. 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 female, contrary
to the usual rule among birds of prey, is smaller than
the male. California Condor's head (adult)Sexual maturity
and breeding behavior do not appear in the condor until
5 or 6 years of age. They may live for 50 years or more,
and mate for life. The South American condor prefers roosting
and breeding at elevations of 3,000 to 5,000 m (10,000–16,000
ft). There on inaccessible ledges of rock, its nest consisting
merely of a few sticks placed around the eggs, it deposits
one or two bluish-white eggs, weighing about 10 ounces
and from 3 to 4 inches in length, during the months of
February and March every second year.
