Pointless albatross

A pointless albatross is a large sea bird that doesn't think twice about flying for thousands of miles without stop. For just a can of anchovies, and the removal of an uncomfortable thing on the bird's leg, it seems to the bird that it's worth a flight of several thousand miles and, after only a short rest, the same length of flight back home. For this reason, the Agatean Empire uses pointless albatross as messenger birds (as other people might use pigeons), often as messenger birds to Ankh-Morpork.

The albatross's pointless missions can be found in: The Colour of Magic, Interesting Times, Small Gods and The Last Hero.
