A haggis is a small animal native to Scotland. Well when I say animal, actually it's a bird with vestigial wings - like the ostrich. Because the habitat of the haggis in exclusively mountainous, and because it is always found on the sides of Scottish mountains, it has evolved a rather strange gait. The poor thing has only three legs, and each leg is a different length - the result of this is that when hunting haggis, you must get them on to a flat plain - then they are very easy to catch - they can only run round in circles.
After catching your haggis, and dispatching it in time honoured fashion, it is cooked in boiling water for a period of time, then served with tatties and neeps (and before you ask, that's potatoes and turnips).
The haggis is considered a great delicacy in Scotland, and as many of your compatriots will tell you, it tastes great - many visitors from the US have been known to ask for second helpings of haggis!
The noise haggis make during the mating season gave rise to that other great Scottish invention, the bagpipes.
A little known fact about the haggis is its aquatic ability - you would think that with three legs of differing lengths, the poor wee beastie wouldn't be very good at swimming, but as some of the Scottish hillsides have rather spectacular lakes on them, over the years, the haggis has learned to swim very well. When in water, it uses its vestigial wings to propel itself forward, and this it can do at a very reasonable speed.
Haggis normally give birth to two or more young Haggis, or "wee yins", as they are called in Scotland, and from birth, their eyes are open, and they are immediately able to run around in circles, just like their parent.
The wee yins are fiercely independant, and it is only a matter of weeks before they leave the parent, and go off foraging for food on their own, although it is perhaps a two or three year period before they are themselves mature enough to give birth.
Most Haggis hunters will leave the wee yins, due simply to their size, but when attacked by other predators, they are still able to emit the bagpipe like sound, which again has the effect of very quickly clearing the surrounding area of all predators, and attracting other Haggis to the scene. This results in a very low infant mortality rate, with most wee yins actually making it to adulthood.
The lifespan of the Haggis is again an unknown quantity, but from taggings done in the Victorian era, we know that some haggis live for well over 100 years.
