Our (modern) Explanation
One of the “exotic” birds that were introduced by Dutch sailors in the 1590s. It represents a hornbill from the Indonesian archipealago rather than a South American toucan. However, this misunderstanding is almost as old as the invention.

Early Modern Interpretation
Contemporary
As one of their first tasks in the 1920s, the newly founded International Astronomical Union (IAU) established constellation standards. The Belgian astronomer Eugène Delporte was assigned to the task to define borders of constellations parallel to lines of declination and right ascension. They were accepted by the General Assembly in 1928. The standardized names and abbreviations had already been accepted in 1922 and 1925.
