The story of the word

Named in the 1890s after European outbreaks traced to crates of imported parrots. The winter of 1929 to 1930 produced an international scare, with newspapers running parrot fever headlines, import bans in several countries and a rushed hunt for the organism that infected several of the investigators. The culprit turned out to be Chlamydia psittaci, carried by pigeons and poultry as readily as by parrots, so the disease is also called ornithosis.
