"A solitary Chilean flamingo named Pink Floyd wintered at the Great Salt Lake. He escaped from Salt Lake City’s Tracy Aviary in 1987 and lived in the wild, eating brine shrimp and socializing with gulls and swans. (Pink Floyd is often referred to as a “he,” although the bird’s gender is not actually known.) A group of Utah residents suggested petitioning the state to release more flamingos in an effort to keep Floyd company and as a possible tourist attraction. Wildlife biologists resisted these efforts, saying that deliberate introduction of a non-native species would be ecologically unsound and might have detrimental consequences. Pink Floyd was last seen in Idaho (where he was known to migrate) in 2005. He has not been seen since then and is presumed not to have survived the winter of 2005-2006."
