They go hunting at night and live in the trees. However, New Zealand's Tsarists have demonstrated since last February a totally surprising behavior in these mammals: they act as if they were drunk, come out of day and fall as if something had pushed from the trees. This strange behavior was first shown by laboratory czarices, but there has been a similar phenomenon in every corner of New Zealand.

The biologists who work at the AgResearch research center have attributed this change of attitude of the tsarguides to a virus that has appeared spontaneously and have added that the arrival of the virus has been beneficial. New Zealand's peasants are the enemies of these small mammals.

Zarigueia is a species from America and Australia that is still in the process of adaptation. Until it gets used to the new medium, it produces great slaughter in the native fauna. On the other hand, the zariguía population has grown disproportionately in recent years and all control systems have failed so far. In view of all this, we can wonder to what extent this new virus has come of itself. At the moment there is no answer.
