Just been watching a Nat Geo show called Python Hunters. It follows three licensed python hunters capturing Burmese pythons in the Everglades. Two of them are breeders, and one is a biologist. The great thing about this show is that they go to great lengths to shoot down in flames all the hysteria surrounding these animals. For example; the Burms have no natural predators. King snakes take out a lot of hatchlings, so do birds of prey. In one show they looked into how they became a problem in the first place. Their conclusion was that there are two separate issues. There are those that are found around human habitation, these are in the minority, and are predominantly released or escaped pets. These animals aren't a threat, they always come off second best. The majority of Burms out there are in the Everglades, and the source has been attributed to the destruction of a holding facility by hurricane Andrew in 1992 that held about 1000 Burm hatchlings. The problem was recognised about ten years later, which makes sense. It would likely take that long for these snakes to mature, and breed, and reach a population saturation high enough for them to need to spread out. Fascinating show.
