As a native of that well know Scottish enclave called Lambeth I was realiably informed when I first came to Scotland to live (about 20 years ago) that catching haggis was fairly simple if you knew which remote highland mountains they frequented. You see a haggis (Haggi Caladonia) has legs slightly longer on one side than the other so it can run round the mountain anti-clockwise very fast to avoid capture but obviously they have trouble changing elevation so once you find one you set up a net and chase the haggis round the mountain and hey presto.

I was also told that there are different sub-species because the higher the elevation the more hair they need to keep warm so Haggi Caledonia - (Munrous baggus) is the rarest as it can only be found above 3000ft and is very difficult to find because it looks like a hairy ball. The more common is Haggi Caledonia - (jimmy wiggus) and is more easily spotted as it tends to develop bright orangey red hair as it matures.

Sorry for some reason I only described the Male of the species - it is the female that runs in the clock-wise direction but they are much much rarer and seldom seen because the gestation and nursing period lasts for about 3 years and regardless of sub-species they have very drab brown fur except for the one week they are "in-season" when they develop, almost instantaneously, a nordic blonde coat!
