No! Not the 4 legged type. The legless type, and not from being out on the town and boozing up. These are quiet and peaceful (depending on how big you are of course, some small animals would object to that description).
Boiga irregularis, Night Tigers, are quite common around here. Last night while on my Cane Toad patrol I came across these two prowlers. The first was just around the 1 metre mark in length. The second was about 1.5 metres long. At a quick glance they could be mistaken for Darwin Carpet Pythons which are also common around here.
Of course, in some places a sighting of Night Tigers (also called Northern Brown Tree Snakes) would ring alarm bells and cause a search and destroy mission to be initiated. Back around the WWII years while cargo was being whisked around the globe some of these snakes hitched a lift to Guam which they found very much to their liking. They settled in and with an endless supply of unwary prey bred like crazy. Of course the "endless supply" wasn't really all that endless, as far as individual species were concerned. These became extinct. But there were no natural controlling agents for the snakes. These days a lot of money is being spent trying to eradicate them.
