He approaches the female with his neck outstretched, revealing the inflated neck and the chest patch, hissing, then extends his wings and stands erect while clicking his tongue. During courtship displays, the skin of the male's neck flushes, changing from dull red to bright yellow, and inflates.

The irises of the male are brown, while those of the female are deep red. The beak is hooked and adapted to tear rotting meat. The feet are thus more adapted to walking and are of little use as weapons or organs of prehension as in birds of prey and Old World vultures. The middle toe of the Andean condor is greatly elongated, and the hind one is only slightly developed, while the talons of all the toes are comparatively straight and blunt. Juveniles are grayish-brown, but with a blackish head and neck, and a brown ruff.
