In Australia a common nickname for redheads is “Ranga” which is an abbreviation of orang-utan. To try and draw attention to the plight of the animal the Adelaide Zoo ran an advertisement offering “Free Zoo Entry for all Rangas” during school holidays.

The campaign generated a large negative reaction to the request reports the Zoos director of conservation programs. “People are possibly more sensitive then we thought” Kevin Evans said.

The exhibit was to bring to peoples attention that since human redheads are becoming an endangered species (which is not true) we could empathize with the same plight of the orangutans being endangered.

The Zoo has since changed their policy and will not seek proof that patrons are not natural redheads.
