I have mixed views regarding hybrids and 'unusual' colour forms. There are certainly some valid points mentioned in some of the previous posts but one aspect that I find quite interesting concerns the ability of these 'freaks' to draw the crowds. Here in the UK most collections rely solely on the gate for the income. It therefore seems logical that the amount of money a collection receives from admissions will have a direct bearing on how much cash they can release to support in situ conservation work. If a liger / tigon / white whatever can bring in extra visitors and raise extra money, shouldn't they therefore be viewed as potentially beneficial? I would hazard a guess that the average visitor does not decide to help tiger conservation (as an example) because of the colour of the tiger in front of them, or because its parents were different species. I often here the argument that these animals 'take up valuable enclosure space' that could be more appropriately used for a pure bred animal but i'm not overly sure that this is a valid argument. To my knowledge, the various tiger studbooks contain animals that are, in effect, genetically redundant, either due to age, genetic over representation, or studbook mismanagement in the past (as in the Asian Lion studbook where one of the founders was discovered to be a hybrid). Surely these animals are also taking up valuable space? Many people are quite happy to see these as they represent a (hopefully!) pure species / sub species, but will angrily denounce a money spinning hybrid. The reality of conservation is that we need money to make it happen - maybe a display of ligers with appropriate interpretation is one way of approaching the problem.
