Unwanted Visitors to New Zealand

Close up of the stoat, weasel, and two ferrets. They are perfectly created to fit down rabbit burrows, keep in undergrowth and move through small gaps to find their food.

Another view including the possum, who, unfortunately, had an accident with its tail, in that it dropped off when the animal was first lifted out of its box!
You can see the difference in sizes more clearly within this shot.
