The Fuchskusu (Trichosurus vulpecula), in the English linguistic area as Common Brushtail Possum designation, is most frequent the largest Kusu and the marsupial mammal which can be found in Australia in cities.

Table of contents

occurrence

domestic was it in south and east Australia. It is one of the few kinds, which prospers both in cities and in variety of natural and of human being-coined/shaped landscapes well. They are considered in many places similarly as Waschbären in North America as annoying co-inhabitants. In New Zealand they occur in large number and are considered as a parasit.

Perhaps the Fuchskusu was introduced also to North America and Europe, could not settle here however because of the Raubtiere not in larger numbers.

description

of the Fuchskusu is approx. long and 25 - 40 cm long tail the male weighs up to 4 kg, the females only 1.5 - 3.5 kg have 35 -55cm.

nutrition

it eats mainly sheets, supplements its food however with fruits, eddy lots, blooms, buds and other one. In the neighbourhood of humans they prove as inventive food procuring parties with a preference for fruit trees, vegetable gardens and raids in kitchens. They avoid the plentifully existing Eukalyptusblätter contrary to other Australian Blätterfressern, apparent can them the poison materials contained in many kinds not neutralize.

way of life

of the Fuchskusu is night active. Tags sleeps the Kusu in a nest in a tree cave or at another suitable place, as rabbit-build, sheds or not reliably locked cover areas in buildings are likes. Although they are mainly tree inhabitants and do not occur in treeless areas, one finds them regularly also at the soil.

That very loud, hissing call, which the male uses to the aggressive Verteidiung of its territory, is trueful uncanny in the night. They have different stimmliche expressions, which consist mainly of Klicks. Usually they are relatively calm.

Vermehrung

of the Fuchskusu can cross with the Hundskusu and perhaps also different related Kusus.

They form groups of approximately a dozen of individuals with for dominant factors a female at the point. The males guard the group, if new generation is thereby. In the mating time both males and females pull also outside of their traditional territory around. The female throws only one young per year after 17 days. This remains further 4 months in the bag.

use

although in some areas forbidden, they deliver good domestic animals, if sufficiently tree-covered area is available. One can feed it easily with the vegetarian portion of the human food.

Kusufelle were around 1900 much like. Australia e.g. exported. 1906 4 million skins. European settlers introduced 1858-1920 more than 600 Kusus to New Zealand , in order to develop a fur industry here.

Kusus as a parasit

today gives there it because of the absence of natural Fressfeinden to about 70 million Fuchskusus. They are ecologically harmful, since they up-eat the domestic vegetation. Breitblättrige trees are particularly endangered such as Rata, it lead to the damage of the crowns of tree and possibly supplement its food with young birds. They do not have so much influence on the south beech (Nothofagus), but their presence reduce the diversity of species of south Buchwald, which they many of the other kinds occurring here dezimieren. Attempts to exterminate or at least their number reduce it, were employed with traps and poison, showed however only briefly success. The used poison, usually Kaliummonofluoroacetat or Zyanid are even environmentalharmful. In order to prevent damage to young trees, one must hold the individual number very small, perhaps 5% of the number existing without interference. The Fuchskusu seen therefore in New Zealand as large ecological threat and also environment organizations to demand their extermination. Their damage adds up with those of other imported kinds, like red deer and house goats as well as human activity such as land and forestry and mining industry.
