The Macaroni Penguin is a very rare vagrant to
South African waters (with a handful of sightings),
and is somewhat larger than the Rockhopper Penguin (about 70 cm).
It inhabits the sub-Antarctic Islands
of the Southern Indian and Atlantic Oceans.
A set of two stamps commemorating Chile's
Territory (issued 1995), and illustrating the Macaroni Penguin.
The derivation of the name “ Macaroni” is interesting.
The Macaroni Dandies were young men of fashion in the 18th century,
who wore, among other things, feathers in their caps
(mentioned in the song “Yankee Doodle”).
The similarity must have struck the namers of the Macaroni Penguin.
This stamp, issued by F.S.A.T. in 1987,
seems to illustrate the "feather in the cap" beautifully.
