The Andean condor (Vultur gryphus) is a South American bird in the New World vulture family Cathartidae and is the only member of the genus Vultur. Found in the Andes mountains and adjacent Pacific coasts of western South America, the Andean condor has a maximum wingspan of 3.2 m (10 ft 6 in). The Andean condor was described by Swedish scientist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae and retains its original binomial name of Vultur gryphus.

The condor soars with its wings held horizontally and its primary feathers bent upwards at the tip.
There is a well-developed social structure within large groups of condors, with competition to determine a 'pecking order' by body language, competitive play behavior, and vocalizations. Generally, mature males tend to be at the top of the pecking order, with post-dispersal immature males tending to be near the bottom. @Robert Clark @thephotosociety
