Andean condor (female)

Description:

Although it is on average about seven to eight cm shorter from beak to tail than the California Condor, the Andean Condor is larger in wingspan, which ranges from 270 to 320 cm (8 ft 10 in to 10 ft 6 in). It is also typically heavier, reaching a weight of 11 to 15 kg (24 to 33 lb) for males and 8 to 11 kg (18 to 24 lb) for females. Overall length can range from 100 to 130 cm (3 ft 3 in to 4 ft 3 in). The adult plumage is a uniform black, with the exception of a frill of white feathers nearly surrounding the base of the neck and, especially in the male, large patches or bands of white on the wings which do not appear until the completion of the bird's first moulting. The head and neck are red to blackish-red and have few feathers. The head and neck are meticulously kept clean by the bird, and their baldness is an adaptation for hygiene, allowing the skin to be exposed to the sterilizing effects of dehydration and ultraviolet light at high altitudes. The crown of the head is flattened. In the male, the head is crowned with a dark red caruncle or comb, while the skin of his neck lies in folds, forming a wattle. The skin of the head and neck is capable of flushing noticeably in response to emotional state, which serves to communicate between individuals. Juveniles have a grayish-brown general coloration, blackish head and neck skin, and a brown ruff. (information from Wikipedia)

Notes:

This spotting took place at Oklahoma City Zoo. I threw the last image in because it shows the nictitating membrane as the bird is blinking.
